Site: PAT-8C
Seismic line
Site location map

Priority: 1
Position: 8°53.089´N, 135°21.992´W
Water Depth: 4817 m (uncorrected)
Sediment Thickness: 283 m (0.344 s TWTT)
Target Drilling Depth: 281 m
Approved Maximum Penetration: 400 m
Seismic Coverage: EW9709 PAT-8 seismic survey

Objectives: The objectives of Site PAT-8C are to:

1. Determine the nature of sediments deposited at the late Eocene equator

2. Determine the paleolatitude of the drill site

3. Determine the rate of accumulation and types of biogenic sediments

4. Collect an Eocene/Oligocene boundary section above the CCD

Drilling Program: One APC/XCB to basement; second and third APC/XCB to basement if time is available.

Logging and Downhole: Triple combo, MGT, FMS-sonic. WSTP check shots if time is available.

Nature of Rock Anticipated: Soft sediments except perhaps some chert-chalk in basal layers. Basement is midocean ridge basalt.
