What Is MARS?The Undersea Cable Observatory
• Allows scientists to monitor their instruments in real time
• Connects
equipment to a power supply
• Sends data
instantaneously to researchers' computers

Eye-In-The-Sea
• Sensitive camera that records bioluminescent sea creatures
• Uses only red light for
illumination • Lures animals into
visibility

ALOHA Mooring
• Buoy, half-mile long cable, vertical profiler
• Other instruments can be
attached to float • Constantly measures
salinity, temperature, oxygen, and backscatter in water column

Seafloor Seismometer
• Part of 880 seismometer network
• Sits West of San
Gregorio Fault, monitors Pacific plate
• Gathers valuable
information about the earth's interior

Benthic Rover• Mobile lab that charts
deep-sea carbon cycles
• Measures oxygen
levels in sediment • Can function up to a
year

Deep-Sea Environmental Sample Processor
• Robotic DNA lab that tests for new life forms
• Contains all the chemicals,
computers, and containers of a full-size laboratory
• Has to deal with the cold and
extreme pressure of the deep sea

History• MBARI put team together: University of
Washington, NASA, Woods Hole Oceanographic Institute
• NSA approved grant in September 2002
• First Obstacle: drilling permits
• Second Obstacle: the medium voltage power system
• Finally put together on site in February 2008
• Power connector on TRF failed after 20 minutes
• Fully operational November 2008
