AKA: none

Other ID: Escanaba 2022; TN-403

Status: Pending

Organization(s): USGS, Pacific Coastal and Marine Science Center

Funding Program(s): Other (Other)

Principal Investigator(s): Amy Gartman

Affiliate Investigator(s): Amanda Demopoulos (USGS); Nancy Prouty (USGS); Kiana Frank (University of Hawaii); Isobel Yeo (Southampton); John Jamieson (Memorial University); Joe Resing (NOAA)

Information Specialist(s):

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.

Vehicle(s):

Start Port/Location: Newport, OR

End Port/Location: Newport, OR

Start Date: 2022-05-24

End Date: 2022-06-13

Equipment Used: Push corer, Hand-grab sample, Gravity Core, High Temperature Major Samplers, High Temperature Gas Tight Samplers, Magnetometer, Camera-video, Side-scan sonar, CTD - FSI, niskinbottle, PMEL MAPR

Information to be Derived: Mineral distribution; metal sulfide geochemistry; species distribution; microbiology distribution; water column chemistry; hydrothermal fluid chemistry; sediment geochemistry; organic geochemistry
