Nathaniel (Ben) Cohen Nathaniel (Ben) Cohen
Computer Technician
Scripps Institution of Oceanography

Ben Cohen is a Scripps computer technician. While an undergrad studying computer science, Ben Cohen was fortunate enough to parlay an on-campus student job with the Scripps Institution of Oceanography into summer voyages on two different scientific research expeditions — traveling by sea from Japan to Hawaii to San Diego while collecting data to help model large scale climate variability. After graduating from the University of California - San Diego, Ben signed up with Scripps Institution of Oceanography full-time where he has spent the last seven years as part of a group of scientific technical staff applying his knowledge of obscure digital domains to support a myriad of operations on Scripps research voyages.  When not at sea, find Ben clinging for life on a remote rock-face or enjoying an espresso as part of a never ending quest to discover the world’s best coffee shop.

Ben vividly remembers attending an auditorium full of thousands of students in middle-America one otherwise normal school day for what turned out to be a live-video tele-conference with cutting edge scientists at sea and their powerful instrument of exploration: the Jason ROV.  He remembers being fascinated by all the technical wizardry needed to make that event happen (and remembers also feeling some small amount of jealousy toward the lucky student allowed to remotely operate one of the ROVs cameras).  It’s not without a sense of childish excitement that after all these years he is now going to see the modern version of Jason in action firsthand from the deck of the R/V Revelle.

Bob (Jason) Elder Bob (Jason) Elder
Research Engineer, retired
Woods Hole Oceanographic Institution

Bob Elder has been working in Oceanographic Engineering for about 33 years.  After getting a degree in electrical and electronic engineering from San Diego State University, he began his oceanographic career with Scripps working on the Deep Tow project under the direction of Dr. Fred Spiess. Deep Tow was one on the first towed underwater instrument platforms supporting a slow scan TV, film cameras, and an assortment of sonars for gathering science data as well as navigation data. A few years later, Bob relocated his family from sunny California to historic New England when he was offered an opportunity to work with Woods Hole Oceanographic Institution in the Deep Submergence Lab. There he was instrumental in the development, design, and construction of the ROV Jason, one of the first underwater robots that used a fiber optic cable for communication. Jason has continued to evolve and currently supports over 10 TV cameras, 2 manipulators, as well as a host of purpose-built scientific sensors for gathering data and samples.  After about 25 years as a Jason engineer, Bob left the tethered vehicles behind and joined the REMUS group, working on autonomous underwater robots. These robots are completely self contained and will run for 24 hours collecting data before returning to the surface for recovery, allowing researchers to gather data that was previously unattainable. Throughout his career, Bob has racked up well over 100 sea trips, proof that the sea is in his blood. As if that weren’t enough time at sea, he and his wife have recently acquired a 42-foot trawler and plan to write the next chapter in their life, starting in the summer of 2015, cruising the Eastern seaboard and Bahamas in their new home away from home.


Dave Emerson Dave Emerson
Senior Research Scientist
Bigelow Laboratory for Ocean Sciences

David Emerson has been interested in the microbial iron cycle for over 20 years in both marine and terrestrial environments. His work focuses on understanding the natural history of iron-utilizing microbes in their environment. This knowledge is applied to learning more about the ecological relationships among bacteria within iron-cycling communities and to laboratory studies aimed at isolating new iron-oxidizing microbes and understanding how they can live on iron. He has been involved in numerous research cruises to active volcanic seamounts and deep-ocean ridge systems using either human or robotic deep-sea submersibles. Along with Craig Moyer, he discovered the Zetaproteobacteria, a novel class of Proteobacteria that are involved in iron oxidation and are dominant members of the microbial iron mats that are a focus of this expedition. These bacteria produce novel biomineral structures in the form of filamentous sheaths and stalks that can become fossilized, thus are interesting bacterial biosignatures for investigating life in ancient environments on Earth, and in the search for life on other worlds. Emerson is a Senior Research Scientist at Bigelow Laboratory for Ocean Sciences in East Boothbay, Maine. He is the Principal Investigator for the National Science Foundation proposal that led to this expedition. He is a graduate of the College of the Atlantic and received a Ph.D in Microbiology from Cornell University.

Sheryl MurdockSheryl Murdock
Graduate Student
University of Victoria

Sheryl Murdock has recently transitioned into graduate school at the University of Victoria in Canada after 18 years as a research technician at both the University of Washington and University of Victoria. Her primary experience has been in studying the microbial ecology of prokaryotes (bacteria and archaea) in diffuse fluids and microbial mats associated with hydrothermal vents and oxygen minimum zones. This has included culturing of high-temperature organisms as well as molecular techniques to assess microbial community diversity and functional gene abundances. A project which has been an interest of hers for over a decade has now become the focus of her graduate studies working with Dr. Kim Juniper. On the current cruise, she will be investigating the roles that microbial eukaryotes (protists) play in ecosystem functioning at hydrothermal vents and in surrounding waters. These single-celled organisms, which reside in the same domain of life as more complex multicellular organisms, are not well understood in many areas of the deep ocean and may play a vital role in the oases for life in the deep that occur at hydrothermal vents.
