Other ID: 91

Status: Completed

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

Funding Program(s):

Principal Investigator(s): Bradford Butman

Affiliate Investigator(s):

Information Specialist(s):

Data Type(s): Environmental Data: CTD, Environmental Data: Temperature, Imagery: Photo, Location-Elevation: Navigation, Sampling: Biology, Sampling: Chemistry, Sampling: Geology, Sonar: Single Beam, Time Series: Mooring (physical oceanography)

Scientific Purpose/Goals: Collect CTD and suspended matter samples and deploy two moorings in Lydonia Canyon. Collect surface grab samples near Lease Block 312 (for analysis of texture, trace metals, petroleum hydrocarbons, and benthos). Collect grab samples at four long-term stations for benthic seasonal and transport changes. Collect grab samples to map surficial sediment in Lydonia Canyon.
