Department of Estuarine and Oceans Sciences - SMAST Seminar
The School for Marine Science and Technology Department of Estuarine and Ocean Sciences Seminar Announcement "Activities and productivity of the Sub-Seafloor Biosphere at Deep-Sea Hydrothermal Vents" Dr. Stefan Sievert Associate Scientist Woods Hole Oceanographic Institute Wednesday, April 25, 2018 12:30 pm to 1:30 pm SMAST East, Rooms 101/102 836 S. Rodney French Blvd, New Bedford Abstract: Despite 40 years of research, knowledge of in situ metabolism of microbes carrying out carbon fixation in marine hydrothermal systems is still very limited. Particularly lacking are studies identifying the chemosynthetically active microbes and measuring rates of CO2 fixation in situ. Here, I present data from innovative incubations that maintained seafloor pressure and temperature for assessing chemoautotrophic production in deep-sea vent systems. Overall, our data provide a comprehensive view of the sub-seafloor biosphere underlying the studied vent site and its biogeochemical significance for the surrounding deep ocean.

Department of Fisheries Oceanography / SMAST seminar - April 25, 2018 - Dr. Hollie Putnam
Department of Fisheries Oceanography Avenues of Marine Invertebrate Acclimatization in Response to Rapid Environmental Change Dr. Hollie Putnam Assistant Professor Department of Biological Sciences University of Rhode Island Wednesday, April 25, 2018 2:30 pm - 3:30 pm SMAST-E rm. 101/102 836 South Rodney French Boulevard, New Bedford, MA Abstract: The swiftly changing climate presents a challenge to organismal fitness by creating a mismatch between the current environment and phenotypes adapted to historic conditions. Rapid compensatory response to environmental change generated by epigenetic mechanisms and the emergent properties of symbiosis can provide a temporal buffer for genetic adaptation. My research focuses on these acclimatory mechanisms that may be especially crucial for sessile benthic marine systems, such as reef-building corals and bivalve mollusks, where climate change factors including ocean acidification and increasing temperature elicit strong negative physiological responses including bleaching, disease, and mortality. By integrating across biological scales from molecular to ecological in a series of preconditioning experiments to future temperature and ocean acidification, we documented evidence of intra and trans-generational acclimatization and parental effects in geoduck clams and corals. Furthermore, our findings support a role for Symbiodinium shuffling in coral holobiont performance and DNA methylation in phenotypic plasticity in corals. Induction of potentially heritable phenotypic plasticity via preconditioning or parental effects may provide mechanisms with significant implications for sessile marine organism persistence under rapid climate change.

Department of Fisheries Oceanography - PhD Dissertation Proposal Defense
The School for Marine Science and Technology Department of Fisheries Oceanography PhD Dissertation Proposal Defense "Standardized Catch Rates to Support Data-limited Stock Assessment and Fishery Management" by Alexander C. Hansell advisor Dr. Steven Cadrin Monday, May 7, 2018 11:00 am SMAST East, Rooms 101/102 836 S. Rodney French Blvd, New Bedford, MA Abstract Understanding population dynamics is essential for implementing effective conservation and management of coastal sharks. Fisheries-independent surveys can offer valuable information for such data-limited situations. A12-year (2004–2015) standardized, shallow water longline survey was conducted monthly in the coastal waters of Bimini, Bahamas. Each monthly survey comprised five longline sets, totaling 75 hooks, with a soak time of 24 h. A total of 770 sharks from nine species were caught over the course of the study, with tiger (Galeocerdo cuvier), nurse (Ginglymostoma cirratum), blacktip (Carcharhinus limbatus) and lemon (Negaprion brevirostris) sharks comprising 95% of the catch. Most tiger (87%), nurse (62%), blacktip (67%), and lemon (82%) sharks were of immature lengths. A greater number of captured tiger (77%) and blacktip (66%) sharks were female, while nurse (55%) and lemon sharks (73%) were predominantly male. Poisson generalized additive models were used to analyze local abundance trends and examine how catch rates were influenced by year, month, location, tide, hour of capture, and lunar cycle. Seasonal trends indicate greater catches of the nurse, blacktip and lemon sharks during the summer months. Annual trends indicated relatively stable catch rates for the tiger, blacktip and lemon shark. Nurse shark catch rates were highly variable during the survey. Results from this study improve our understanding of the coastal shark assemblage in Bimini, Bahamas, and provide important local abundance trend information that could be beneficial for conservation and regional assessments.
