Principal Investigator(s): Eric Grossman

Affiliate Investigator(s):

Information Specialist(s): Bruce Richmond

Data Type(s): Sampling: Geology

Scientific Purpose/Goals: Sub-sample cores of opportunity provided by the US Navy

Vehicle(s):

End Port/Location:

Start Date: 2003-04-30

End Date: 2003-05-02

Equipment Used: pushcore

Information to be Derived: Fossil coral species composition, fossil coral ages, and coral/sediment accretion histories. Sediment grain size.

Summary of Activity and Data Gathered: Five 80-ft (20-inch diameter) pilings filled with 4 to 20 m of fossil coral reef and sediment from the Pearl Harbor shelf were subsampled for their contents. Pilings were driven into shelf in water depths of 60 ft to 150 ft as part of a US Navyís characterization of substrate integrity for outfall project. Twenty meters of 2-in diameter, lined core samples and 25 bag samples of branching and massive corals were collected from pilings. Sample lithology, coral species composition, and radiometric ages will be used to determine reef and sediment accumulation history and depositional environments during the Holocene sea-level transgression.
