ABSTRACT A scientist's record of scholarly publications serves as a lasting
testament to their interests, commitments and passions. Dr J. Mark
Erickson has over 45 scholarly publications demonstrating his
longstanding commitment to undergraduate research, his exceptional
scholarship, and his interest in the regional geology of both the North
Country and North Dakota. Dr. Erickson's commitment to
undergraduate research started long before it was fashionable, as
seen by his first publications in The Compass, the journal of Sigma
Gamma Epsilon. His bibliography includes publications in prestigious
journals like Nature and the Journal of Paleontology, illustrating the
high quality of his scholarship. Smaller organizations like the New
York State Geological Association and the North Dakota Academy of
Sciences also benefitted from his contributions. Dr. Erickson often
chose to work with current and former students, co-authoring with
them on many publications. In addition to Dr. Erickson's bibliography,
his other vital contribution to the geological sciences is the group of
scholars and students he taught and mentored during his time at St.
Lawrence. Many of these students have gone on to have illustrious
careers as geoscience scholars, thanks largely to the education they
received from Dr. Erickson and St. Lawrence University.

THE PUBLICATION RECORD OF DR. J MARK ERICKSON Dr. Erickson has a broad and interesting publication history. His first peer reviewed paper was published in the Compass of Sigma Gamma Epsilon (Erickson, 1969) prior to the completion of his PhD dissertation in 1971. Over the next 41 years, his publication history was remarkably consistent (see figure 1), averaging at least one publication a year, not including national and regional conference presentations (of which there were many). While many researchers hit a peak in their 50s (Gingras et al., 2008), Dr. Erickson has continued his research at a similar rate although his co-authors have shifted from his mentors to his students and former students over time.
Dr. Erickson has published in a wide range of journals. Depending on the topic, he has published in high impact publications such as Nature and the Journal of Paleontology, as well as local and regional publications (see table 1). He has contributed to local conferences and field trips, writing for the New

York Geological Association Guidebooks and submitting papers to regional conferences about the Great Lakes, the North Country and the Grass River.
Dr. Erickson has published on a wide range of topics in paleontology, stratigraphy and biology. He has concentrated his work in three main geographical regions: the North Country of New York, North Dakota and South West Ohio. Additional locations include Glovers Pond, New Jersey and the Holocene Hiscock site in Western New York.
He has worked on rock units in those areas familiar to his paleontology students: The Fox Hills formation of North Dakota, the Potsdam Sandstone of Northern New York, and the formations that make up the Cincinnati Arch.
Dr. Erickson has published research on a wide variety of extinct and modern invertebrate species including snails, clams, mites and bryozoan. He has even found the time to publish and present research about vertebrate species and plant fossils found in his study areas.
A basic topic analysis of this publications can be done by creating a word cloud out of his publication titles, emphasizing his major interests in the Fox Hills Formation of North Dakota and topics associated with it (see figure 2).
Exclusive of conference presentations, Dr. Erickson has collaborated with others on 27 of his 45 publications. Most commonly he works with one other collaborator but has written 8 papers with three authors, 2 papers with 4 authors and is listed among the 27 authors in a recent paper by St. Lawrence University geology alumnus Dan Peppe ’03 (Peppe et al., 2011). Dr. Erickson has published fewer single author papers in the last 10 years, but continues to collaborate closely with one or two co-authors for each publication.
Of these co-authors, many were current or former students. This commitment to undergraduate research started long before the 1998 Boyer Commission report on undergraduate research made it fashionable (Katkin, 2003). Early publications with students often appeared in The Compass of Sigma Gamma Epsilon or regional publications (e.g. Klett & Erickson, 1974), but latter student (and former student) publications have appeared in a wide variety of journals.

CITATIONS TO DR. ERICKSON’S PUBLICATIONS The impact of Dr. Erickson on the geological literature extends beyond his own publications to those researchers who have found Dr. Erickson’s research useful and cited them in their own work. Citations to these publications can be found in multiple databases including Web of Science (Thomson), Scopus (Elsevier) and Google Scholar.
Scopus and Web of Science list 120 publications that have cited Dr. Erickson’s work over time. This can be considered a minimum possible number for two reasons. First, only a quarter of Dr. Erickson’s publications are listed in Web of Science or Scopus, since he chose to publish in many small or regional journals. While these works may have received the most citations due to their ease of discovery other cited works exist. Second, many of the works that might cite Dr. Erickson’s work may not be listed in the two citation databases.
The first citation to Dr. Erickson’s work appeared in an article in the Journal of Sedimentary Petrology in 1977 (KELLING and MOSHRIF, 1977) and was followed by a relatively quiet period until his work started to be cited more in the late 1980s. The lag between Dr. Erickson’s early publication record and his citation record may be the result of the relatively low circulation of the first journals he published in (i.e. The Compass of Sigma Gamma Epsilon, the North Dakota Academy of Science Proceedings, etc.).
Citations to Dr. Erickson’s work have increased exponentially since the early 1980s (figure 3). Early citations came mostly from The Journal of Sedimentary Petrology, Sedimentary Geology and Geology. In recent years, Dr. Erickson’s work has been cited by international journals including publications from India, Canada, Britain, France, Denmark, Poland, and New Zealand.

His most cited paper is from the Journal of Sedimentary Petrology (now the Journal of Sedimentary Research) and was co-authored with a former student, Scott Carpenter, ’85 (Carpenter et al., 1988). It has been cited 20 times in Scopus, 35 times in Web of Science, and 57 times in Google Scholar (see Yang and Meho, 2006, for a description of the differences between the resources).
Dr. Erickson’s research has been useful to a wider variety of subjects than he perhaps originally envisioned. Biological journals such as New Phytologist, Marine Ecology and the American Journal of Botany now make up a large portion his citing references (table 2).
In addition to citations, some researchers are also beginning to examine other uses of a scholars work. Known as altmetrics (Priem et al., 2011), these tools allow researchers to see how

their works are being read or shared with others by examining article downloads, mentions in news stories or elsewhere on the web, or how often an article is saved to a citation network such as Mendeley (http://www.mendeley.com) or CiteULike (http://www.citeulike.org). The altmetrics analytical tool ImpactStory tells us that several of Dr. Erickson’s works have been saved to these citation networks, and at least one of his works has been cited on Wikipedia. The brief entry about Ischyodus (http://en.wikipedia.org/wiki/ischyodus) cites a 2005 publication from Palaeontology (Hoganson and Erickson, 2005). The complete ImpactStory analysis of Dr. Erickson’s publications (only those that have a DOI are included) is available online here: http://impactstory.it/collection/nxvs5l
A word cloud created from article titles that cite Dr. Erickson’s research demonstrate the usefulness of this work beyond his primary study areas. Researchers studying paleoclimates, modern invertebrates and geochemistry have cited Dr. Erickson’s work (figure 4).
WORK OF DR. ERICKSON’S STUDENTS Although Dr. Erickson’s publications will continue to be read and cited for years to come, his greatest influence on the field of geology may be the group of students he taught during his tenure at St. Lawrence University. This influence is seen in the contributions of these students to their chosen fields. Many St. Lawrence University geology alumni have gone on to pursue academic careers and their own record of scholarly publication. Some have co-authored with Dr. Erickson during their time at St. Lawrence or long after their graduation.

During his time at St. Lawrence University, Dr. Erickson supervised at least 63 senior theses, starting in 1974.
Working from the list of Geology department theses, I was able to identify 91 publications by former students who completed senior theses supervised by Dr. Erickson. While some have continued to work in paleontology or stratigraphy, others have expanded their interests into igneous petrology, paleoclimatology, botany and physical anthropology. An online bibliography of these publications is available at the website of Mendeley, the citation manager and discovery tool.
Certainly, this list of 91 publications is a gross underestimate of the work done by Dr. Erickson’s students. Some alumni didn’t complete a thesis but went on publish extensively. Others (including this author) completed a thesis with another advisor but consider Dr. Erickson an important influence in their professional careers.
In order to add to this list of 91 publications, a public bibliography has been created using Mendeley. The Mendeley group, Publications of former students of Dr. J. Mark Erickson is open to the public and can be found online at http://www.mendeley.com/groups/2638941/publications-of-former-students-of-dr-j-mark-erickson/. Alumni are invited to join Mendeley and add their publications to this list. Alternatively, contact Bonnie Swoger ’99 ([email protected]) with details of your publications to be added to this list.
TOTAL IMPACT By combining the publications from Dr. Erickson, his students and the articles that cite Dr. Erickson, we can get a more complete picture of Dr. Erickson’s impact on the scientific literature. We can compare the journals on this list of publications to the map of scientific fields created by analyzing citation patterns in the journal literature from Web of Science (Börner et al., 2012). Using the Sci2 analysis tool (Sci2 Team, 2009), we can visualize the fields that have been influenced by Dr. Erickson and his students (figure 5).
While much of his influence is concentrated in the Earth Sciences (as expected), his work is almost as influential in biology, with some topical coverage in chemistry. Small circles in unexpected disciplines (brain research, health professions) are artifacts of publications in general topic journals such a Nature, PLOS ONE, and the American Journal of Science.
