Other ID: A-1-03-PW

Status: Completed

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

Funding Program(s): Oxidation of Sulfides (MU223)

Principal Investigator(s): Randy Koski, Pat Shanks

Affiliate Investigator(s):

Information Specialist(s): Randy Koski

Data Type(s): Sampling: Geology, Imagery: Photo

Scientific Purpose/Goals: Determine extent of Acid and Metal Flux into Intertidal Zone

Vehicle(s):

Start Port/Location: Valdez, AK

End Port/Location: Valdez, AK

Start Date: 2003-06-03

End Date: 2003-06-08

Equipment Used: VanVeengrab, gravitycore, underwatercamera

Information to be Derived: Distribution of mine wastes along the shoreline; extent of sulfide oxidation and resulting flux of acid and metals into the intertidal and subtidal zones.

Summary of Activity and Data Gathered: Collected about 50 samples of fresh surface water, pore water, and seawater (pH, alkalinity, conductivity, and dissolved oxygen analyzed in the field, IC and ICP-MS analyses in USGS labs); collected about 30 rock (sulfides), 15 sediment (mud), and 8 precipitate samples (analyzed by ICP-MS in USGS labs).
