Tim ShankDr. Timothy Shank

Dr. Timothy Shank, an Associate Scientist in the Biology Department at the Woods Hole Oceanographic Institution, will oversee data collection and analysis, including molecular phylogenetic, phylogeographic, and population genetic analyses, as well as interpretations and publications on the connectivity of invertebrate coral associates across hard-bottom habitats.  Dr. Shank is one of very few people who combines multiple molecular genetic approaches and ecological field studies to understand the conditions and adaptations that allow various species to migrate, evolve, and thrive in deep-sea habitats, including chemosynthetic, seamount, and cold-water coral ecosystems. Dr. Shank received his undergraduate degree in Biology and German from the University of North Carolina at Chapel Hill, worked two years with award-winning papers in genetic toxicology at the Environmental Protection Agency, and received a PhD in Ecology and Evolution from Rutgers University in 1998.  Over the past 10 years, he has published more than 50 peer-reviewed papers with a specific focus on understanding the ecological and evolutionary factors that affect the structure and evolution of populations of diverse deep-sea species.  His expertise in marine phylogenetics and phylogeography have shaped our views on how deep-sea fauna have radiated and evolved in relation to geologic history and chemosynthetic habitat availability on mid-ocean ridges and continental margins. As a Fellow of the Deep Ocean Exploration Institute, his genetic approaches to understanding evolutionary processes that drive patterns of diversity and connectivity in coral ecosystems have led to burgeoning insights on the co-evolution and co-dispersal of coral hosts and their invertebrate associates.  This research has been driven both by the model system that coral hosts and associates provide for fundamental evolutionary biology and by the need to understand the impacts and sustainability of deep-sea fisheries and increasing mineral exploration activities on these deep-water faunas.  Tim was also co-lead investigator and science advisor to the construction of the hybrid remotely-operated vehicle Nereus.  He was integrally involved in developing the scientific capabilities and readiness of the full ocean depth (11km) hybrid ROV/AUV Nereus. Beginning with participating in the initial field programs (May 2009) to the Mariana, Tim will conduct research exploring the extent to which hadal and trench depths and topography promote the formation of species.

Dr. Paul H. YanceyDr. Paul H. Yancey

Dr. Paul H. Yancey is Professor and the Carl E. Peterson Endowed Chair of Sciences at Whitman College (Walla Walla, Washington, USA), where he teaches undergraduate courses in marine biology (for both biology and non-science majors), animal physiology, bioethics (including environmental ethics), and directed research. He has also worked during summers and sabbaticals at Scripps Institution of Oceanography, Oregon State University’s Hatfield Marine Science Center, the National Institutes of Health [medical research], the Mount Desert Island Biological Laboratory (Maine), Stanford University’s Hopkins Marine Station, Louisiana State University, the University of Otago (New Zealand), University of Hawaii’s Oceanography Dept. and Institute of Marine Biology, and the Monterey Bay Aquarium Research Institute. Paul studies biochemical and physiological adaptations of marine animals to physical and chemical factors, specifically water and osmosis, pH, temperature, hydrogen sulfide and hydrostatic pressure. Since 1983, he has gone on numerous deep-sea expeditions using nets, ROVs and the Alvin submersible to collect animals. His specific deep-sea research includes tissue compositions and buoyancy of midwater and bathypelagic fishes, and organic osmolytes in shallow, bathyal and abyssal fishes (hagfish, sharks and their relatives, and bony fish), corals, crustaceans, annelids and echinoderms. Organic osmolytes were originally discovered as small cellular solutes that prevent osmotic shrinkage in most marine organisms, which are faced with the high–and thus potentially dehydrating–salt content of seawater. Paul and other physiologists have found that many of these (and related) compounds have other protective roles. One of these discovered by Paul and his students is the protection of proteins from the inhibitory effects of high hydrostatic pressure in the deep sea. This new mechanism to explain how life can cope with pressure will be tested at extreme depths in the HADES project. Related projects include potential protective roles of osmolytes with respect to sulfide and temperature stresses at cold seeps and hydrothermal vents. Finally, his work on osmolytes in sharks led to i) the use of certain osmolytes in biotechnology for stabilizing biomolecules, and ii) the discovery that mammalian kidneys use the same kind of solutes to protect their cells from the stresses of processing salts and waste products; and as a result, Paul has also worked extensively with medical researchers.
