Equipment Used
|
|
|
Purpose
|
|
Sub-sample cores of opportunity provided by the US Navy
|
|
|
Information to be Derived
|
|
Fossil coral species composition, fossil coral ages, and coral/sediment
|
|
accretion histories. Sediment grain size.
|
|
|
Summary
|
|
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 Navy’s 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.

Got Help?
|
For W-1-03-HW, we would appreciate any information on -- contract, days at sea, dive count, funding, kms of navigation, national plan, NGDC Info, notes, owner, platform, ports, project number, publications, scanned materials, seismic description, station count, station description, submersible, tabulated info.
