USGS Coastal and Marine Geology Program

Field Activity Details for field activity 2000-022-FA

Other ID: MK-0100; IB S-22-00-HW

Status: Completed

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

Funding Program(s):

Principal Investigator(s): Michael Bothner

Affiliate Investigator(s): Mike Field, CMGP-Menlo Park

Information Specialist(s): Michael Casso

Data Type(s): Location-Elevation: Navigation

Scientific Purpose/Goals: Two one-day trips were conducted to recover sediment cores using a modified USGS gravity corer and a slide hammer corer. Two sediment traps were deployed near depressions in the reef platform. Scientific objective is to assess the impact of soil erosion from Molokai on the health of the adjacent coral reef.


Start Port/Location: Kaunakaki, HI

End Port/Location: Kaunakaki, HI

Start Date: 2000-01-27

End Date: 2000-01-29

Equipment Used: DGPS, Corer - gravity

Information to be Derived:

Summary of Activity and Data Gathered: SCUBA diving was under the direction of the Menlo Park Dive Team. Sediment traps were deployed in <2 m water near the USGS tripod off Hotel Molokai. Other sediment traps were deployed by the west coast team after Feb. 1 along CRAMP transects.
