Field Activity Details for field activity 2022-647-FA

AKA: none

Other ID: Mud 1n

Status: Pending

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

Funding Program(s): Other (Other), Subtidal-intertidal sediment exchange (MU281)

Principal Investigator(s): Nancy Prouty

Affiliate Investigator(s): Amanda Demopoulos Wetland and Aquatic Research Center; Jill Bourque Wetland and Aquatic Research Center

Information Specialist(s): Joanne Thede

Data Type(s): Seismics: Sub Bottom Profiler, Environmental Data: CTD, Sampling: Geology

Scientific Purpose/Goals: Between 5-27 Sept, 2022, we will conduct multicore deployments, subbottom profiling, and CTD operations within impact zones and reference areas in the northern Gulf of America (Gulf of Mexico) in response to the 2010 DWH Oil Spill.

Vehicle(s):

Start Port/Location: Gulfport, MS

End Port/Location: Gulfport, MS

Start Date: 2022-09-05

End Date: 2022-09-26

Equipment Used: 0.5-16 kHz receiver, 0.5-16 kHz, CTD - FSI, multicore

Information to be Derived: Summary of Objectives: Deploy multicore for quantitative sediment sampling of the expanded sediment impacted zone and reference sites. Conduct subbottom profiling over survey areas to groundtruth seafloor multibeam mapping efforts. These data allow surficial sediment thickness to be quantitatively measured, can reveal information about sub-surface controls on seep localization and hard-bottom occurrence, and provides important constraints on interpreting surficial sedimentary processes. Define water column oceanographic and nutrient properties using CTD rosette casts and water sampling at priority sites.Collect eDNA samples from CTD casts at select locations.
