    Table of Contents

    At the Boston OCEANS conference electionswere held for several officers and the results arepresented in the Secretarys write up elsewhere inthe Newsletter. My term was renewed for anothertwo years. There are several areas that I would liketo address in this issue.

    A proposal to simplify the budget process forthe IEEE and the Societies so that a more pre-dictable procedure can be followed has beendeveloped and will be voted on in mid Novemberat the TAB level for execution in 2008. It is a fun-damental change in the accounting for IndirectInfrastructure charges. The proposal will havedirect impact on our budget but in the long run it should makefor a more predicable approach to our annual budget formation.We are in good financial shape as we have about 1.5 milliondollars in reserve that has been built up over the years. If youhave any questions relative to the budget or its process pleasecontact or Treasurer, Jerry Carroll at [email protected].

    This is the second year we have run two major conferencesthe June event was detailed in the previous issue. The fall eventin Boston was well attended- about 2000- as well as having about500 papers. The society now has a set of web tools that helped toalleviate some of the time consuming tasks for the conferencecommittee. The conference had a very visible presence from ourcolleagues in Canada both in papers and organizationally. The

    numbers arent finalized as of this writing but itappears that we exceeded our budget surplus.Thanks to John Irza and his committee members.

    Our next major event will be in AberdeenScotland in June an event not to be missed. TheAberdeen Exhibition and Conference Centeralong with the banquet at Fyfie castle will be longremembered. The committee also has a surpriseevent for the attendees .In addition to OCEANS,the European Commission will hold EuroOceansin the same venue on Friday of the same week.For those who will come early the HighlandGames are scheduled for the weekend prior to the

    conference. John Watson and his committee are looking for-ward to supplying the attendees both a fine technical programand a great social event. For details see the society web pagewww.oceanicengineering.org.

    In conjunction with the Signal Processing Society , the Non-linear Statistical Signal Processing Workshop was held at Cam-bridge University in September. There were about 120 regis-tered attendees out of a total of 135. The event was alsosupported by ONR Global . Jim Candy was the spearhead andhe is hoping to make this a periodic event. Thanks to Jim andhis colleagues at Cambridge for their time and effort.

    Stan Chamberlain is leading an effort to produce a history ofthe society as we will be celebrating our 40th year in 2008. The

    Presidents Corner

    project is progressing nicely with the help of Robert Colburn ofthe IEEE History Center serving as the editor. If you have anyhappening that you feel is appropriate please contact Stan sothat it can be considered for inclusion. We are planning to havethe document ready by January of 2008.

    Over the past couple of conferences the society has developeda series of web tools for the conference committees to ease the bur-den on the volunteers. They include the following: Content Man-agement System, Abstract and Paper Management, ElectronicCopyright, and Integrated Registration Systems. Todd Morrisonand Rene Garello have been the motivating forces behind thiseffort. They were implemented by Veraprise our web developers.In addition the final copy of the CD that is sent to IEEE for inclu-sion in IEL is an output as the systems afford the proper format forthis action. Todd also has developed a training session for anyonewho is involved in the conference planning and implementation.

    The society is instituting a scholarship program for bothundergraduate and graduate students. Candidates must beenrolled full-time in an accredited collage or university in a fieldof study that will lead to a career in ocean engineering or a relat-ed ocean science.For detailed information relative to the pro-gram contact Norm Miller, our student programs coordinator.

    The society has established a Chapter in Houston onceagain. The chair is Gamal Hassan. The IEEE/OES is now amajor contributor to the OTC Technical Program Committee,(TPC) due to Gamals efforts

    At OTC 2007, OES will be responsible for the following:

    Observations is continuing and expanding. The ICEO is a focalpoint for the technical and engineering expertise that IEEE andthe member societies can bring to bear on this world wide effort.The committee is represented in several of the GEOSS areas ofinterest e,g., Architecture and Data,User Interface, CapacityBuilding, Renewable Energy , Science and Technology and Stan-dards and Interoperability. As one can readily see this is an ambi-tious undertaking and the committee could use anyone with somerevelent expertise to assist in any of this areas. This is a globaleffort and many hands are needed to accomplish the objectives.

    If you havent renewed you membership yet please do so. Infact it would be extremely helpful if you could also get a col-league to join as you can see that we have a full plate on ourtable. Any questions regarding membership should be directedto Ken Ferer or Jim Collins.

    Jim Barbera, IEEE/OES President

    The purpose of this article is to remind all IEEE members ofthe changes in the IEEE Fellow nomination process thathave taken place over the past several years, mainly in theeffort to generate more Fellow nominations from industry

    Changes were initiated in 2003 - to the Fellow process and to the appropriate IEEE By-Laws - to assure equalopportunity for election to IEEE Fellow grade of memberswith careers involving the application of technology. Thechanges actually took effect for the Fellow class of 2005.

    The IEEE Bylaws were amended to clarify the eligibil-ity of Application engineers and Practitioners, and toestablish the realization of the significant value to societystandard for evaluating nominations. Fellow candidatesare now classified as Application Engineer / Practition-er, Research Engineer / Scientist, Technical Leader, orEducator.

    Another important step in modernizing the Fellow nomi-nation process is that the nomination forms and instructionsare available on the IEEE Web site and that the nomination

    forms can now be submitted electronically. See the IEEEWeb site at (www.ieee.org/fellow).

    Although electronic submittal of Fellow nominations ishighly recommended, and is the preferred method of submittal,the forms and instructions are also available in hard copy (viaE mail to [email protected]). Nomination forms are able to besubmitted in either hard copy, or electronically via the WEB.The Class of 2007 Fellow nomination

    cycle ends March 1st, 2007.All questions on the Fellow nomination process - or general

    Fellow questions should be referred to the IEEE Fellow staff E mail [email protected].

    IEEE Fellow grade membership is bestowed by the Boardof Directors on IEEE Senior Members with an extraordinaryrecord of accomplishment in any IEEE field of interest. Theaccomplishments honored shall have contributed signifi-cantly to the advancement of engineering, science and tech-nology, bringing the realization of significant value to soci-ety.Oceanic Engineering Society Scholarship Program

    BREAKING NEWS!!!

    OCEANS 07 Aberdeen & EurOCEAN 2007In conjunction in Aberdeen, Scotland from 18-22 June 2007

    First Time for either in the UK!

    These major OCEANS and MARINE Conferences will join forces to bring theworld-wide marine community of scientists, engineers, technologists andpolicy makers together in a frame-work of easy and informed discussion.

    An exhibition of oceanic industry and research institutions will run side-by-sidein the state-of-the-art Aberdeen Exhibition and Conference Centre (AECC)

    The theme of Oceans 07 Aberdeen, Marine Challenges: Coastline to Deep Sea, highlights thesignificant challenges; from the shallowest waters around our coasts to the deepest subsea trenches,which face marine and oceanic engineers in our drive to understand the complexities of the worldsoceans and our ability to utilise, explore and preserve this unique environment. Oceans will run from18-21 June 2007.

    The focus of EurOCEAN 2007 will be a consultation, discussion, and analysis of the EuropeanCommissions recently published Green Paper on a future Maritime Policy for the EU.This policy isaimed at optimising the economic value of all maritime sectors in a socially and environmentallysustainable way. EurOCEAN 2007 will take place on 22 June 2007 and will play a major role in theconsultation process with the marine RTD community.

    The Chairs of Oceans 07 Aberdeen and EurOCEAN 2007 invite you to participate in thisunique event.Aberdeen has a long and distinguished pedigree in maritime affairs stretchingback a thousand years through exploration, shipbuilding, fishing and science and engineeringto its position now as the oil and gas capital of Europe.

    It is fitting that Aberdeen is the first UK city to be chosen to host both Oceans andEurOCEAN and the first to host the joint event.

    OCEANS 2006 MTS/IEEE BostonThis was a most successful conference as reported in this issue,This conference was first recognized by RECON (OES Confer-ence Development) in 2002, a four year lead time. John Irza wasidentified as the lead person and later designated as ConferenceChair. Four years ago, our concern was focused on the BostonBig Dig massive road redirection, and will it be completed intimeand it was. RECON efforts are seldom remembered. Ifyou tell someone you helped start it four years ago, they just rolltheir eyes. In this case, John Irza paused to remember.

    Conference Development (RECON Reports)Bob Wernli continues to do a very creditable job as OESReconnaissance (RECON) Committee Chair. In Boston, atthe OES AdCom and RECON Meetings, Bob Wernli report-ed progress on Future OCEANS Conferences out to 2013.His report is summarized below.

    FUTURE OCEANS CONFERENCE STATUSOCEANS 07 Aberdeen, June 18-21, 2007 and OCEANS 07MTS/IEEE Vancouver, September 20-25, 2007 are under thecognizance of the Joint Oceans Advisory Board (JOAB).

    Chile-US Ocean Engineering Workshop/SymposiumThis has been on the radar screen since 2003. The firsteffort involved working with Prof. Victor Gallardo, Univer-sidad de Concepcion (in Concepcion, Chile) introduced tome by Sandy Williams at OCEANS 2003. A preliminaryproposal was prepared jointly with Gallardo, who, unfortu-nately was unable to obtain adequate support from his Uni-versity and resulted in cancellation. I contacted Prof. HughRudnick, former IEEE Region 9 Director and proposed thatthe IEEE Chile Section take the lead. We have only 3 OESMembers in Chile according to OES Membership ChairKen Ferer, who is participating in this effort. Prof. Rudnickprovided the E-mail addresses of the Section Chair and oth-ers, who were receptive to a cooperative effort.The IEEE Chile Section sent a Letter of Interest for aWorkshop or Symposium in Chile. The Section namedGaston Lefranc, Vice Chairman of IEEE Chile Section, asthe link between the Section, OES and the local organiza-tion. He contacted the Oceanic Group of the School of SeaSciences (Grupo de Oceanografia de la Escuela de Cien-cias del Mar), Catholic University of Valparaiso (PUCV).Dr. Sergio Salinas is in charge to organize the possibleWorkshop or Symposium and to talk with IEEE. They haveconcern about the procedure and financial issues. A jointproposal will be prepared to solicit support for grants amdservices.

    At the beginning of 2001, Ren Garel-lo headed the Oceanic EngineeringSocietys Committee on ConferencePolicies chartered to establish Confer-ence Policies and Procedures thatensure continuity between successiveOCEANS Conferences. This commit-tee, jointly with the Marine TechnologySociety, developed the Two OCEANS

    Conferences policy adopted by both societies; One OCEANSConference each year in Northern America, and one OCEANS

    Conference every odd year in Europe or every even year in theAsia-Pacific region.

    Then, with members from both societies, Dr. Garelloformed the Joint OCEANS Advisory Board to develop uni-fied operating procedures for OCEANS Conferences.Thanks to his vision and leadership, OCEANS Conferencecommittees now have a permanent OCEANS website facil-ity with web-hosting tools, capabilities for electronic pro-gram and registration operations, and tailorable contractorsupport.

    Fred Noel Spiess, a world-renowned deep-seaocean explorer and inventor at Scripps Institu-tion of Oceanography, University of California,San Diego, died Friday, Sept. 8, 2006, in UCSan Diegos Thornton Hospital in La Jolla,Calif. The cause of death was cancer. Born inOakland, Calif. on Christmas Day, 1919, he was86 years old.

    Spiess had been affiliated with Scripps Oceanographysince 1952. He was a professor emeritus of oceanography inthe Marine Physical Laboratory (MPL) at Scripps and had along and successful scientific career that spanned more than50 years.

    Spiess was widely known for his contributions to thedevelopment of innovative ocean technology. He was tirelessin defining new ways to look at the deep ocean and seafloor.He designed and built instruments, took them to sea fordeployment and led numerous expeditions to investigate thedeepest parts of the worlds oceans. He was co-inventor of theone-of-a-kind FLIP, the Floating Instrument Platform.

    We are deeply saddened to hear of Fred Spiesss passing,said Marye Anne Fox, chancellor of UC San Diego. Fredwas a brilliant innovator in ocean science who dedicateddecades of enthusiastic leadership to the development of UCSan Diego and to the University of California. Through hisparticipation on numerous committees over the years, he hashelped UC San Diego become a national academic and scien-tific leader. Today, our hearts go out to his family as wemourn his loss and express our deep appreciation for hisdevoted years of service.

    Fred Spiess was the embodiment of an oceanography pio-neer and his influence in marine science will be rememberedforever, said Charles Kennel, director of Scripps Oceanogra-phy. On the Scripps campus he will be celebrated as some-one who made the type of pivotal contributions that made thisinstitution a world leader in its first 100 years. Everyone atScripps will miss his academic eminence, his personalintegrity and his friendly demeanor and smiling face.

    Spiess received his A.B. degree in physics from UC Berke-ley in 1941, and received a U.S. Navy commission at thesame time. During World War II he completed 13 war patrolsin submarines in the Pacific Ocean and won the Silver Starand Bronze Star. He held the rank of captain (retired) in theU.S. Naval Reserve until his death.

    After the war, Spiess attended Harvard University, receiv-ing his M.S. degree in communication engineering in 1946.He then returned to UC Berkeley for graduate study inphysics, where he conducted research under Emilio Segr inthe area of short-lived alpha decay problems and high-energyparticle scattering and absorption.

    He completed his Ph.D. degree in 1951, then workedbriefly for General Electrics Knolls Atomic Power Laborato-ry in Schenectady, NY. In 1952 he joined the Marine Physical

    Laboratory (MPL) at Scripps and was director of MPL from1958 to 1980.

    He spent the year 1962-63 as acting director of Scrippsand was director for the academic year 1964-65, followingRoger Revelles resignation and preceding the appointment ofWilliam A. Nierenberg. He was then an associate director ofScripps until 1980. He also served as chairman of the ScrippsGraduate Department in 1963-64 and 1976-77. During 1974-75, while on leave from Scripps, he was a scientific liaisonofficer for the Office of Naval Research in London.

    From 1980 to 1988 he was director of UCs Institute ofMarine Resources (IMR), headquartered at UC San Diego,retaining his faculty association with Scripps and continuinghis research in MPL. As director of IMR, the universitys onlystatewide marine science unit, Spiess coordinated a diversityof research interests at the inter-disciplinary institute con-cerned with research, education and public service in relationto societys uses of the resources of the sea.

    Spiess was the co-designer, along with Fred Fisher andPhillip Rudnick, of FLIP, a 355-foot long, non-propelledresearch vessel. This unique research craft flips from a hori-zontal to a vertical position to form a steady platform for

    research at sea. In 2002, FLIPmarked 40 years in active serv-ice at Scripps. At the time ofhis death, Spiess was involvedin arranging for the use ofFLIP as a testing and demon-stration platform for researchand engineering systems to bedeployed in ORION (OceanResearch Interactive Observa-tory Networks), a new oceanobservations program.

    Spiess was a seagoing scientist, leading an average of twoexpeditions a year for more than 40 years. His research inter-ests included studies of long-range propagation of sound andrelated underwater communication systems, ocean-going sta-ble platforms and deep-towed instrument systems, fine-scaleproperties of the deep seafloor, phenomena associated withplate tectonics and seafloor spreading and seafloor geodesy.

    In 1989 he led the development of a wireline re-entry sys-tem to carry research instruments from the deck of a shipthrough 5,000 meters of seawater and into seafloor boreholespreviously drilled as part of deep-sea scientific drilling pro-grams. He conducted the first, highly successful use of thesystem off Florida during a cruise of the Scripps research ves-sel Melville. He continued to lead the refinement and use ofthis capability, with a 2001 expedition on R/V Revelle mak-ing the first wireline installation of thermistor strings in drillholes to study the circulation of fluids in the earths crust.

    Spiess was principal investigator for several programs atthe East Pacific Rise (EPR) and the Mid-Atlantic Ridge. He

  • led an international expedition to the EPR at 21 degrees northin 1979, when hot springs, oases of unusual marine life andrare mineral sulfide deposits were discovered at depths of2,600 meters.

    Spiess worked on the development of seafloor search tech-nology and in 1971 led a successful deep-sea expedition thatlocated and mapped the wreckage of five ships previouslyscuttled by the U.S. Navy. He also carried out National Sci-ence Foundation-supported manganese nodule surveys,Navy-sponsored studies of the acoustic properties of the deepseafloor and a variety of geological and geophysical expedi-tions in the Pacific, Atlantic and Mediterranean oceans. Hepioneered the development of seafloor geodesy, developingand proving techniques for measuring positions on the deepseafloor with centimeter repeatability.

    Spiess wrote numerous technical articles on subjects inmarine physics and ocean engineering. He served on a varietyof advisory committees and study groups, including the NavalResearch Advisory Committee; the Defense Science Board; theNational Academy of Sciences committees on undersea war-fare, oceanography and geodesy; the steering committee for theNSF RIDGE program; and advisory committees for marineprograms at UC Santa Cruz, UC Santa Barbara, the Universityof Miami and Woods Hole Oceanographic Institution.

    He was chair or co-chair for more than 20 successful Ph.D.candidates, four of whom are now full professors in the Uni-versity of California system.

    He was a fellow of the American Geophysical Union, theAcoustical Society of America and the Marine TechnologySociety, and a member of the Maritime Historical Society, theSociety for Industrial Archeology, Sigma Xi and Phi BetaKappa. During 1990-92 he was president of the Ocean Sci-ences section of the American Geophysical Union andchaired its Fellows Committee in 1994-96. He was also anactive member of the Scholia Club of San Diego.

    In 1965 he was awarded the Franklin Institutes WetherillMedal for his role in the development of FLIP. He received theMarine Technology Societys Distinguished Achievement Awardin 1971. He was presented the U.S. Navys highest award for sci-entific achievement, the Captain Robert Dexter Conrad Award,in 1974 for outstanding achievement in planning, conductingand administration of research and development.

    In 1980 the American Association for the Advancement ofScience awarded Spiess and his coauthors the NewcombCleveland Prize for the outstanding paper published in Sci-ence that year. In 1983 he received the Maurice Ewing medalfrom the American Geophysical Union and the U.S. Navy foroutstanding contributions to marine geophysics. In 1985 hewas awarded the Acoustical Society of Americas Pioneers ofUnderwater Acoustics medal and the Lockheed Award forOcean Science and Engineering from the Marine TechnologySociety.

    In 1985 he was elected a member of the National Acade-my of Engineering for significant breakthroughs in oceanengineering, including the development of FLIP, Deep Towand precision benthic navigation. In 1990 he received theNavy Distinguished Service Award for leadership in oceantechnology. Most recently, he was awarded the 2006 Distin-

    guished Technical Achieve-ment Award from the OceanicEngineering Society of theInstitute of Electrical andElectronics Engineers for sixdecades of advances in oceanengineering while developingsea-going research tools. Hisdaughter Kathy Dallaire willaccept the award on his behalfon September 20.

    Spiess served the University of California Academic Senateboth locally and UC-wide. At UC San Diego, he was chair ofthe Committee on Planning and Budget during 1986-88, theGraduate Council in 1983-84, the Committee on Privilege andTenure in the 1970s and chair of the San Diego Division in1985-86. He served as vice chair and chair of the UC-wide Aca-demic Council and Assembly in 1988-89 and 89-90, respective-ly, including acting as one of the two faculty representatives onthe UC Board of Regents during that period. From 1998 to 2001he chaired the UC Academic Senate Task Force for the startupof UCs new campus at Merced. His contributions in this arenawere recognized in 2000 with the Oliver Johnson Award for out-standing service to the Academic Senate.

    At Scripps he served on and chaired many committees,including Scripps Staff Council (1962-64). He was a leader inthe restoration of the historic Old Scripps Building, includingserving on the Building Restoration Committee (1976-87).He was awarded the UC San Diego Campus Ministry Awardfor academic leadership in 1989.

    Perfect autumn weather pro-vided the ideal setting for theOceans06 Conference andExhibition in Boston this pastSeptember. The event washosted at the Hynes Conven-tion Center in the fashionableBack Bay section of downtownBoston. With over 2100 atten-dees, more than 350 technicalpresentations, and 190 exhibi-tion booths sold, Oceans06was unquestionably successfulbeyond our predictions.

    The conference began onMonday September 21 with aday filled with tutorials andworkshops. This event markedthe first time that ContinuingEducation Units (CEUs) wereawarded for participation incertain tutorials.

    The traditional Mondayevening ice breaker reception

    had a sell-out crowd of people renewing friendships andgetting caught up on the latest news of whos doing what.

    Tuesday morning officially marked the beginning of theOceans06 Technical Program and debut of the expansiveExhibition Hall. The kickoff plenary was introduced byAndy Clark of Oceans.US, and focused on Ocean Observ-ing Systems and featured Dr. Margaret Leinen, the Assis-tant Director for Geosciences at the National ScienceFoundation; Dr. Richard Spinrad, the Assistant Adminis-trator of the National Oceanic and Atmospheric Adminis-tration; and Dr. Jose Achache, the Group on Earth Obser-vations (GEO Secretariat Director).

    Tuesday also marked the reprise of the Exhibitor Prod-uct Showcase, first implemented at Oceans 2000 in Provi-dence, Rhode Island. This year the Exhibitor ProductShowcase offered over twenty technology-oriented presen-tations given by exhibiting companies.

    Wednesdays plenary started the days events with apresentation by Rear Admiral Timothy McGee, the Com-mander of the Naval Meteorology and OceanographyCommand. The MTS awards luncheon was popular as ever,

    with a standing room only crowd of attendees.Wednesday evening the attendees were treated to a

    reception at the Boston Museum of Science, sponsored bythe Canadian Consulate of Boston, followed by theOceans06 banquet and gala. The entire Blue Wing of themuseum was reserved for our use as well as the Theatreof Electricity which offered the opportunity for hardysouls to travel up in the air in a wire cage and have life-sized lightning bolts discharged at them! The eveningsactivities concluded with a side-splitting performance bynationally known comedian Jimmy Tingle.

    Thursday, the final day of Oceans06 was opened with aplenary by RADM Brad Mooney (ret), who was the Chiefof Naval Research until 1987. The traditional IEEE OESluncheon featured the elevation of Rene Garello to Fellowof the IEEE.

    In closing, I would like to state my deepest gratitude toeveryone who has participated in the planning and execu-tion of this event including the Conference Committee,IEEE Conference Management Services, and most impor-tantly the spouses and families of everyone who spent theiravailable time organizing this Conference.

    The nineteenth Student Poster Program was held at OCEANS06 MTS/IEEE Boston. Once again there was a very fine displayof student posters located in the center of the exhibits area at the Hynes Convention Center inBoston, MA. The posters were prominently displayed and werewidely viewed by the conference attendees. The Student PosterSession was organized by Dr. Alexandra Techet from MIT. 49poster abstracts were received and 24 were selected for presen-tation. Poster abstracts were obtained from students in the US,Canada, France, Italy, Russia, China, Venezuela, and the UK.The program was supported by funding from the Office ofNaval Research and from the National Science Foundation.A new event was the addition of a Poster Precis prior to thebeginning of the poster display. Each student gave a brief con-cise overview of the project in 2-3 slides to the judges panel, fel-low students and guests. This introduction gave the judges agreat overview of the work as well as an opportunity to the stu-dent to give an oral presentation. The awards for the winningposters were presented at the Wednesday evening Gala at theMuseum of Science. Two level of awards were given. First toGraduate Students and second to undergraduate students.

    Abstract - Recent interest in ocean exploration has broughtabout a desire for developing wireless communication tech-niques in this challenging environment. Due to its high attenu-ation in water, a radio frequency (RF) carrier is not the opti-mum choice. Acoustic techniques have made tremendousprogress in establishing wireless underwater links, but they areultimately limited in bandwidth. A third option is optical radia-tion, which is discussed in this paper. One drawback of under-water wireless optical communications is that the transmissionof the optical carrier is highly dependent on water type. Thisstudy examines some of the challenges in implementing an opti-cal link in turbid water environments and attempts to answerhow water clarity affects the overall link.

    I. IntroductionNow more than ever, wireless radio frequency (RF) communi-cations are an essential part of military and civilian activities.Land-to-land and land-to-air systems are vital for transmittingdata over large distances without the need for a cable connec-tion. Underwater vehicles and devices may also benefit from awireless link. Military platforms like submarines and unmannedunderwater vehicles (UUVs) would gain the ability to coordi-nate missions and pass data between platforms while at speedand depth. Commercial oceanographic applications stand toprofit as well. Data logging sensors such as seismometers ortemperature sensing devices obtain the capability to transmittheir data without the need to be recovered or unmoored. It iswell known however, that while radio frequencies have enjoyedrelatively large success in free space, they experience highattenuation in water, and are typically not used for communica-tion between subsurface vehicles and devices.

    Acoustic radiation has managed to overcome this issue tosome extent. Typically, data rates of >100kHz have beenreported for links

  • niques and hardware from the radar community. The main dif-ference is that the carrier is in the form of optical energy, ratherthan radio waves.

    Radar and communication systems are characteristicallysimilar systems. The foundation of many of the digital modu-lation schemes used in terrestrial links are related to basic radardetection techniques and use similar hardware components. Assuch, we can use the modulation that FAMIS provides to cre-ate an underwater wireless optical communications link.

    Specifically in this work, a Phase Shift Keying (PSK) linkis examined. In PSK, digital data is represented as changes ina sinusoidal phase. For a k-bit system, the number of symbolsis m=2k where a PSK symbol is defined as

    For simplicity, a binary phase shift keying (BPSK) link isimplemented here (k=1, m=2).

    III. Implications Of Establishing Optical Links in WaterThe main challenge of implementing an optical link underwateris that the optical signal is highly variable with water opticalproperties. An optical signal is attenuated in water by twoprocesses, absorption and scattering. The absorption and scat-tering coefficients, and respectively, are wavelength depend-ent. Absorption losses occur as photon energies are lost due tothermal processes. Scattering losses occur when the interactionwith particulates causes photons to scatter out of the main beampath. It is often more convenient to represent these lossestogether as the total attenuation. The attenuation coefficient, , isdefined as,

    For an incident optical source with power, , the receivedpower, at some point d meters away is,

    Table 1 shows some representative absorption, scattering,and attenuation coefficients for various water types [12].

    When the receiver is viewing the optical signal off-axis(which is a likely operational scenario), the received power is afunction of the attenuation coefficient and the volume scatter-ing function,. The volume scattering function describes theangular dependence of scattered light. The received power isthen defined as,

    The impact of water clarity on an underwater optical com-munications link should now be apparent, as both absorptionand scattering have different effects depending on the environ-ment. For example, in pure sea water, absorption will ultimate-ly be the limiting factor with increasing distance. In this case,

    we can choose a laser source whose wavelength is optimized sothat it experiences a minimum amount of absorption. Thisranges from blue to green wavelengths depending on waterclarity. Furthermore, the fact that the beam remains relativelycollimated over a given path length in clean water imposesextra pointing requirements on the system since the transmitterand receiver would have to be well aligned. It is plausible thatbeam divergence (whether natural due to range, or imposed viaoptics) may relax this requirement, however the operationalenvironment (on a submarine or UUV) may prohibit makingphysical changes on the fly.

    On the other hand, in turbid harbor waters, scattering maybe the limiting factor. Here, the well-collimated nature of laserlight is virtually destroyed as photons begin to scatter out of themain beam path. From a system standpoint, this may be a ben-efit in that we are able to relax the pointing requirements sincethe optical signal now starts to approach that of an isotropicsource. However, scattering may have a similar adverse effecton optical signals that multipath reflections have on acousticsignals. Several studies have investigated the

In the case of amodulated carrier, such as the BPSK link examined here, wewish to examine how water clarity, particularly the off-axisscattering of photons, affects the transmitted modulated RFsubcarrier.

    To this end, we define a modulation depth,

    where is the incoming modulated component of the opticalsignal and is the non-modulated, or DC, component. Ideally,the modulation depth is unity. However, depending on trans-mitter/receiver alignment, link range, RF modulation wave-length, and water turbidity, the possibility exists that loss ofmodulation could occur. From a communications perspective,loss of modulation depth translates directly into received sig-nal-to-noise loss, and therefore a higher probability of bit error.As such, it is important to understand what role scattering hason the modulated optical signal.

    IV. Experimental Setup and ProcedureA block diagram for the laboratory BPSK link is shown in Fig-ure 2. Experiments were conducted in a 1m x 1m x 3.66m watertank with windows on each end. Maalox antacid was used as a

  • scattering agent [14] and a transmissometer was used to direct-ly measure the attenuation coefficient in the testing tank. Thetransmitter and receiver are located outside the tank on oppositesides. At the transmitter end, a frequency-doubled diode-pumped solid-state laser (532nm) is used as the optical source.While this laser has a maximum adjustable output power of 5W,an output setting of 3W is used in this study. The CW opticalsignal enters an electro-optic modulator that has a modulationbandwidth of approximately 10-100Mhz. A carrier frequency of70Mhz was chosen for these experiments. A programmable fre-quency synthesizer was used to generate the RF carrier signal.This source can be programmed to store the PSK symbols inmemory. In the case of the BPSK link implemented here and asdefined by (1), two 70Mhz sinusoids 180 degrees apart fromeach other are stored. After losses through the modulator andother optical elements, the optical power entering the tank isapproximately 500mW.

    At the receiver end, a photomultiplier tube was used torecover the RF modulation envelope. A PMT was chosenbecause of its low noise/high gain characteristics. In addition,the PMT chosen has a 2in. aperture (approximately 18 degreesFOV when housed with biasing electronics). The large activearea was chosen in order to collect as much of the scatteredlight possible.

    The signal is then passed through a custom bias-T to sepa-rate the RF and DC components. The DC side is lowpass fil-tered and digitized. The RF is bandpass filtered at 70Mhz andamplified by a 30dB low noise amplifier and a 50dB variablegain amplifier. The carrier is then demodulated via an IQdemodulator. The I and Q samples are lowpass filtered and dig-itized. Digitization is done with a National Instruments DAQcard which performs simultaneous sampling of the I, Q, andDC signals.

    The RF source has two channels. While these two channelscan be tuned separately in frequency and phase, they share thesame internal oscillator, and are therefore phase-locked. In thislaboratory implementation, one channel serves as phase modu-lation for the transmitter, while the other serves as the localoscillator reference for the demodulator. While having a sharedphase locked source between the transmitter and receiver isnever likely to happen in a real situation, it does provide a fre-quency and phase locked signal on both ends of the link. Bymaking the link inherently coherent the experiment can focussolely on the effects of the water channel.

    On the receiver end of the tank, the PMT is placed on amotorized rail. Once the transmitter and receiver are aligned,the PMT was moved at 1cm increments off axis. The windowof the tank allows for approximately 30 cm of motion, whichgives a pointing mismatch of roughly 5 degrees half angle rel-ative to the laser source. At each position, 1ms (5000 samplesat 5MS/s) of I and Q data was taken for one of the BPSK phasestates. The phase state is changed (180 degrees as per BPSK),and another 1ms of data was taken. The process is essentiallyequivalent to transmitting a single binary 1 and binary 0 at1kHz. In post processing, smaller integration times can beexamined. In this way, multiple data rates can be examinedfrom one data acquisition measurement. This process isrepeated for increasing water turbidities (increasing Maaloxconcentration).

    V. Experimental Results Part IIt is often useful to describe the undersea environment in termsof attenuation lengths, i.e. the attenuation coefficient multipliedby the physical range at which the system is operating. Figure 3shows the normalized beam spread vs. position for increasingattenuation lengths (water turbidities). This is simply the DCaverage of the modulated signal as measured directly from theDC side of the receivers bias T. Position 0 on the x-axis is theposition where the transmitter and receiver are preciselyaligned. For the cleanest water types (c = ~0.8/m, cd = ~3), wenotice a prominent forward peak that falls off rapidly uponmoving off axis, indicating that little scattering is occurring. Aswater turbidity increases (c = ~24/m, cd = 88) it is easy to noticethe influence that multiple scattering has on the optical signal.At the higher water turbidities, the optical signal becomes large-ly diffuse over the 5-degree measurement range. Furthermore,we observe a slight peak that occurs towards the middle of theacquisition range. Here, photons scattered into the near forwardangles are greater than the non-scattered photons. While thisprovides a clear understanding of the effect of forward scatter-ing on the optical signal, it does not yet answer how the RF partof the signal is influenced.

  • The following data is shown for an integration time equal toa 100kHz signaling rate. Figure 4 shows modulation depth asdefined in equation (4) as a function of position. Here, itappears that even at the highest water turbidities there is no sig-nificant loss of modulation with increasing turbidity or point-ing mismatch. (The EO modulator typically achieves 90-100%modulation depth with fine alignment). It should be noted how-ever, that increasing the range of the link, increasing the RFsubcarrier frequency (decreasing the wavelength), or increas-ing the pointing inaccuracy beyond 5 degrees, may in fact showthat modulation loss can occur. This will be discussed later.

    We can also examine the affect of water clarity by examin-ing the phase of the incoming modulated optical signal. As pre-viously mentioned, the link is implemented coherently sincethe receiver and transmitter signals are derived from the samedigital oscillator. The detection, however, is done in a differen-tial sense. In this case, decisions are made not on the absolutephase of the incoming signal but the phase difference betweenadjacent bit periods. As such, differential detection offers areduced system complexity. While differential detection ofcoherent PSK isnt necessarily a common technique, it allowsus to observe some interesting phenomena.

    Figure 5 shows the phase difference between binary statesversus position for increasing water turbidities. The figureclearly illustrates that even at the highest water turbidities, thephase difference between symbols remains 180 degrees, con-sistent with BSPK signaling. These are promising results, as itsuggests that even in the most challenging underwater environ-ments, the phase modulation is largely unaffected.

    As alluded to earlier, an investigation of the absolute phaseprovides some insight into the effect of scattering on the RFsubcarrier. Figure 6 shows absolute received phase vs. positionfor increasing water turbidity for one of the two BPSK binarystates. We notice that from the cleanest water type investigated(c = 0.8 /m, cd = ~3) to the most turbid (c = ~24/m, cd = ~88),the absolute phase shifts approximately 70-80 degrees. This isevidence that multiple scattering is in fact occurring.

    As water turbidity increases, more scattering events occur,and modulated photons take slightly longer path lengths before

    they reach the receiver. This in turn manifests itself as changesin the absolute phase of the carrier. At 70Mhz, in water, the 70-80 degree shift corresponds to a path length difference ofapproximately 0.5m-0.7m (~2ft) between the cleanest and dirt-iest waters examined here. This distance is certainly plausibleover the 3.66m path length given the highly diffuse nature ofthe light observed at those high turbidities.

    VI. Experimental Results Part IIIn the previous section, we examined the influence of waterclarity on a modulated optical signal. In this section, wedescribe an experiment to investigate bit error vs. water turbid-ity and pointing accuracy. Since a bit error generator was notavailable in the lab, one was made in software via LabView. Apattern generator was used to create a 1024 bit pseudorandombit sequence (PRBS) at the rate of 1Mbps. The TTL pattern isfed to the RF synthesizer. The card is programmed so that thechannel driving the EO modulator changes phases based on the

  • pattern generator sequence. The output of the pattern generatoris also digitized by the National Instruments A/D so that com-parisons between the transmitted and received message can beperformed.

    At the other end of the link, the PMT is aligned so that it isoff-axis with the transmitted optical signal (5 degrees, asbefore), giving what should be the worst-case scenario interms of pointing for this particular experimental setup. I andQ samples are then acquired at a sampling rate of 5MHz.Maalox is again added to increase water turbidity. Relativelyclean water is examined first (c= 0.35/m, cd= ~1.26). Figure 7ashows approximately the first 80 bits of the TTL signal gener-ated by the pattern generator and figure 7b the correspondingreceived signal (as changes in phase). Bit decisions were madebased on the incoming changes in phase, and the detectedsequence was compared to the generated sequence. For thiswater type, all 1024 bits were detected error free at a data rateof 1Mbps. Figure 8 shows the resultant polar plot. The tightclustering also shows error free transmission.

    More turbid waters were examined as well (c = 21/m, cd =~71). The 1024 bit sequence was again detected error free. Thepolar plot is shown in figure 9. Both show that the highly scat-tering environment had little appreciable effect on closing thelink. Data rates higher than 1Mbps should be attainable, as thelimiting factor in this work was the available COTS hardwareand not the environment.

    VII. ConclusionsThis work investigated the effects of multiple scattering in tur-bid environments on a modulated optical signal for establishingwireless underwater communication links. Preliminary experi-ments showed that recovery of the RF sub-carrier was largelyunaffected by water clarity. Changes in the absolute phase of therecovered RF envelope vs. increasing water turbidity confirmthat multiple scattering is occurring, however it appears thatunlike acoustic systems, the multipath effects are static duringthe acquisition time. This was supported when short data burstswere detected error free at a rate of 1Mbps.

    While these are positive results, it is important to keep inmind a few limiting factors of the experimental setup. First,while extremely high water turbidities were examined, thegeometry of the tank provided only for a limited range (3m)and limited pointing inaccuracies (5 degrees). While the linkwas successfully established at large attenuation lengths (highwater turbidities at short ranges), it may be unwise at this pointto extrapolate these results to posit on the link quality at longranges (100m and beyond). It is imperative that pointing accu-racy, water clarity, and link range are all considered together.

    To further investigate these three factors, additional experi-ments will be performed in a larger tank facility. The authors atPatuxent River are outfitting an 8m diameter sonobouy tankwith windows. This will allow researchers to investigate theeffect water turbidity has on longer ranges and wider pointinginaccuracies. As mentioned, the observation that scattering hadlittle effect on the modulated RF sub-carrier may simply be dueto the long carrier wavelengths (~3.2m) relative to the shortlink range (3.66m). Likewise, carrier degradation may occurfor pointing mismatches greater than the 5 degrees investigat-

    ed here. This bigger test geometry should give more insightinto the operational limitations of an optical system.

    Future plans also include modeling the optical signal in tur-bid environments. The authors currently possess a beam spreadmodel for investigating the spatial dependence of scatteredphotons. Such a model will allow researchers to obtain a clear-er picture of what kind of pointing accuracies may be neces-sary for a given water clarity. Future upgrades to this modelinclude the addition of time dependence so that metrics relatedto the modulated RF sub-carrier may be investigated.
