Dr. Les Watling
Chief Scientist, Benthic Ecologist
Dr. Les Watling (Ph.D., University of Delaware) currently is a professor of oceanography at the University of Maine. His research interests have principally spanned two areascrustacean taxonomy and phylogeny, and benthic (seafloor) oceanography. His benthic interests are focused on impacts of humans on benthic environments, with an emphasis on organic enrichment and habitat disruption. Recently, he was the co-sponsor of two symposia dealing with impacts of mobile fishing gear on ocean communities, such as the coral beds in the Georges Bank Canyons, and his research projects have focused on the potential loss of marine biodiversity associated with fishing activities. He has conducted much of his current work using research submersibles like Alvin.
Dr. Peter Auster
Dr. Peter Auster (Ph.D., University of Wales) is the science director of the National Undersea Research Center at the University of Connecticut. His research in fish habitat conservation has earned him national recognition. For example, NOAA named him an Environmental Hero for the Year 2000 for his ecologic research at the Stellwagen Bank National Marine Sanctuary. His diving interests and research span three decades and span the globe from the deep lakes of Africa to the reefs of Bonaire, and have included hundreds of dives using occupied submersibles and remotely operated vehicles. Often with Dr. Les Watling, he investigates the impacts of mobile fishing gear on benthic communities off the coast of New England.
Dr. Kevin Eckelbarger
Dr. Kevin Eckelbarger (Ph.D., Northeastern University) is a professor of marine science at the University of Maine. He studies the factors that control reproductive cycles in marine invertebrates, particularly those in deep-water habitats using research submersibles. Through the use of electron microscopy, his research has helped explain how food supply drives egg production in deep water invertebrates, which often have access to limited food supplies. Of particular interest to him are the factors that determine whether a deep-sea species undergoes annual or continuous reproduction, often in the absence of environmental cues (light, food, temperature change) that influence the reproductive cycles of shallow water species.
Dr. Barbara Hecker
Deep Sea Biologist
Dr. Barbara Hecker (Ph.D., State University of New York, Stony Brook) runs her own consulting business, Hecker Environmental Consulting, and is associated with the Boston University Marine Program in Woods Hole, Mass. Her research interests focus on understanding offshore, marine benthic communities and factors that control the distribution of deep-sea megafauna (animals larger than a few centimeters). Since these organisms live on and within the sea floor, much of her work focuses on faunal/geological interactions. Possessing a better understanding of how organisms interact with their environment allows us to better predict possible impacts to the environment from human activities such as fishing and waste disposal. Because the deep-sea habitats she studies are relatively inaccessible, her research also involves devising methodologies (field and mathematical) for conducting large-scale benthic surveys using whatever works best, e.g., trawling, box-coring, dredging, photo-surveys using towed camera sleds, submersibles, remotely operated vehicles and laser line scanners.

Dr. Peter Rona
Dr. Peter Rona (Ph.D., Yale University) is a geology professor at Rutgers University. His research interests include sea-floor hydrothermal systems, ocean ridge processes, the geology of Atlantic continental margins, and the genesis of sea-floor mineral and energy resources. His research program on sea-floor hydrothermal systems involves the development and application of innovative sonar techniques to image the plumes and deep-diving research submersibles, including Alvin. He now is part of a Rutgers research program to determine processes involved in the transfer of natural and anthropogenic materials between the continent and the deep ocean basin. The focus of this program is the continental margin of New Jersey near the Hudson Canyon. He is an expert on the formation of large-scale sea-floor features, such as continental slope slumps and canyons, and is working on the hypothesis that a massive slump feature near the Hudson Canyon was created by the meltdown of a massive gas hydrate bed under the slope during a previous low-sea-level stand.

Dr. Mary Scranton
Dr. Mary Scranton (Ph.D., Massachusetts Institute of Technology / Woods Hole Oceanographic Institution) is a professor in marine sciences at the State University of New YorkStony Brook. Her research focuses on the aquatic cycling of organic compounds in sediments and in the water column. One of her current research programs is examining the importance of bacterial decomposition of organic material in the Hudson River. This seasonal study of bacterial activity in the Hudson River estuary and Western Long Island Sound will determine whether bacteria in the saline portions of the system also use a large component of terrestrially produced carbon. Results of this study will be of interest to managers who are trying to predict the impact of carbon loading on oxygen concentration in the harbor system. She will apply similar work to the Hudson Canyon.

Leg 3Blake Ridge
Dr. Cindy Lee Van Dover
Chief Scientist, Benthic Ecologist
Dr. Cindy Lee Van Dover (Ph.D., Massachusetts Institute of Technology / Woods Hole Oceanographic Institution) is a biology professor at the College of William and Mary. She is a deep-sea biologist with a special interest in the biology of hydrothermal vents and other chemosynthetic communities (ecosystems fed primarily by chemicals as opposed to light). Her numerous expeditions and published papers cover diverse topics such as reproductive strategies and recruitment of vent invertebrates, vent food webs, and taxonomic descriptions of new species. She is the only certified female pilot for Alvin. She qualified in 1990 and was pilot-in- command for 48 dives. Her subsequent research work with Alvin has taken her to nearly all of the known vent fields in the Atlantic and Pacific, as well as to deep-water sea mounts, cold seeps and many other significant deep sea-floor features. These studies contributed to her popular book about the deep sea and her experiences as an Alvin pilot (Deep-Ocean Journeys; Addison-Wesley, 1997) and the first textbook on hydrothermal vents (The Ecology of Deep-Sea Hydrothermal Vents; Princeton University Press, 2000). She will compare the newly discovered chemosynthetic mussel bed on the Blake Ridge with similar beds around the world.

Dr. Joan Bernhard
Dr. Joan Bernhard (Ph.D., Scripps Institution of Oceanography, University of California, San Diego) is a professor in environmental health sciences at the University of South Carolina. Cellular exposure to the lack of oxygen is common at both the organismal (within the body) and environmental level (in aquatic organically-polluted areas). A major focus of Dr. Bernhards work is to establish the effects of little to no oxygen on the survival, behavior and physiology of obligate aerobic cells, using foraminiferans as a model system. This basic scientific investigation is relevant to public health because the occurrence of environmental anoxia is increasing worldwide. Severe pollution pressure in the form of sewage dumping as well as from other anthropogenic activities (e.g., fertilizer runoff) is common, particularly in coastal areas. Oil and gas seeps, such as above the Blake Ridge hydrate bed, are natural settings for high organic input, low oxygen and her studies of such conditions on unicellular life.
