Data Type(s): Environmental Data: ORP, Environmental Data: CTD, Sonar: Sidescan, Sonar: Multibeam, Imagery: Video, Electro-Magnetic: Magnetics, Sampling: Geology, Sampling: Biology, Sampling: Chemistry
Scientific Purpose/Goals: We will be studying the Escanaba Trough to characterize the sulfide minerals and hydrothermal fluids in Escanaba Trough in order to investigate the continuity of both through time; to characterize the ecosystem, including microbes and megafauna inhabiting the trough; and to explore interactions between marine life, the metal sulfide deposits, and the hydrothermal and oceanic environment enveloping both. We will also be doing AUV based mapping.
