"Determining the Resistance of Marine Animals to Environmental Chemicals"

Dr. Mark Hahn, WHOI, Biology Department

Dr. Hahn’s major research interests include receptor-mediated mechanisms of toxicity, and means of adaptation and acquired resistance to exposure to persistent organic pollutants. This presentation centered on looking at toxins in the marine environment, particularly dioxins, PCBs, POPs: the mechanisms of toxicity, what makes animals resistant, genetic markers for resistance.

"Marine Magnetotactic Bacteria"

Dr. Katrina Edwards, WHOI, Marine Chemistry and Geochemistry Department

Dr. Edwards’ research interests include the role of microorganisms in mediating the rates and mechanisms of rock, mineral, and organic matter transformations, and in particular the effects of bacterial films on rocks. This talk was about the discovery of bacteria responsive to the earth’s magnetic field, their abundance and behavior, their ecological niches and importance. Included was a demonstration of how to isolate magnetotactic bacteria from a local marsh and stimulate them to move directionally in response to an external magnetic field.

Mr. Martin Bowen, WHOI, Applied Ocean Physics and Engineering Department

As a Sr. Research Associate in the Deep Submergence Laboratory, Mr. Bowen has been a long-time pilot of the remotely-operated vehicle Jason, and was present when the Titanic was discovered and explored. This presentation was about the history of the development of technology for deep sea exploration, including the ROVs Jason and Medea, the versatility of this type of equipment for undersea work, and the engineering problems and solutions on the way to the current and next-generation ROVs and AUVs (remotely-operated vehicles and autonomous underwater vehicles).

"A New Look at an Old Oil Spill"

Dr. Christopher Reddy, WHOI, Marine Chemistry and Geochemistry Department

Dr. Reddy’s research is concerned with understanding the source, transport, and fate of organic contaminants in the marine environment, using novel analytical techniques. This talk profiled original, current, and ongoing research into a devastating oil spill in a nearby marsh environment, relaying over 25 years of tracking of the hydrocarbon pollution in the marsh, the depth of penetration and the amount of retention and change of the hydrocarbons. Dr.Reddy emphasized that the oil hasn’t gone away in 25 years, that it still can be found in the marsh, and that the effects on the marine community are ongoing.
