OVERVIEW FACS

Topic	Information
Activity ID: 01RCE02	USGS CMG FACS Overview Log
USGS Activity ID	01RCE02 (River Contaminant Evaluation)
Other ID (if any)
Organization	USGS
Project	Evaluate basin/shelf effects in the delivery of sediment-hosted contaminants in the lower Atchafalaya and Mississippi rivers.
Area of Operation	Mississippi Delta (South Pass & Garden Bay), Atchafalaya River, Atchafalaya Delta
Chief Scientist(s)	James Flocks
Information Specialist(s)	Gina Peery
Activity Type	Hi-Res Seismic, Chirp, Sidescan & Vibracores
Scientific Purpose/Goals	To evaluate the storage and transport of particle reactive, environmentally relevant contaminants through the Mississippi River and Atchafalaya River delta complexes to the near-shore Gulf of Mexico.
Platform	R/V G. K. Gilbert
Starting Date	April 25, 2001, JD115
Starting Port	Venice, Louisiana
Ending Date	May 5, 2001, JD125
Ending Port	Morgan City, Louisiana
Equipment Used	Boomer Chirp Sidescan Vibracore
Information to be Derived (e.g., Grain Size, Depth to Basement)	Geophysical data are being used to determine sediment distribution and thickness and to locate sample sites. Sediment cores will be used to evaluate the distribution and concentrations of key contaminants.
Summary of Activity and Data Gathered	Collected 10 single-channel boomer seismic lines and 6 chirp lines in the Mississippi River delta. Collected 5 boomer seismic-lines and 5 chirp lines in the Atchafalaya River delta. 7 Vibracore samples were also taken from the Atchafalaya delta.
