Priority: 2
Position: 20°04.45'S, 151°47.08'E
Water Depth: 360 m
Sediment Thickness: 500 m
Target Depth: 245 mbsf
Approved Maximum Penetration: 650 mbsf
Seismic Coverage: Regional Line MAR-20, shotpoint 7551, CDP 15110

Objectives: The objectives of Site CS-12A are the following.

1. Determine the water depth of the shallowest part of the MP2 platform
2. Determine the age of the MP2 platform drowning
3. Determine the age and duration of unconformities that can be carried into the platform.
4. Calibrate the seismic sequence stratigraphy.

Drilling Program: Single APC/XCB or RCB to 245 mbsf; possibly ADCB of reefal carbonates

Logging and Downhole Operations: None

Nature of Rock Anticipated: Approximately 32 m of hemipelagic ooze overlying 213 m of periplatform ooze and dolomitized reefal carbonates
