Site: 1040R-A

Position: 9°39.7838'N, 86°10.6778'W
Water Depth: 4100 mbsf
Sediment Thickness: 730 m
Target Drilling Depth: 410 mbsf
Approved Maximum Penetration: 920 mbsf; approved to drill without coring to 660 mbsf
Seismic Coverage: Position of site at shotpoint 3122 on seismic line BGR-99-44 (C. Ranero, pers. comm., GEOMAR, Kiel, Germany and C. Reichert, pers. comm., BGR, Hannover, Germany, 2001).
See the track line, seismic BGR-99-44, and seismic CR-20.

Objectives: The objectives of Site 1040R-A are to:

1. Install modified CORKs to monitor pressure and temperature and to sample fluids within the uppermost underthrust sediments.

2. Investigate the décollement.

3.Investigate fluid flow within the décollement and underthrust sediments.

Drilling Program: Install a modified CORK for monitoring fluid flow, pressure, and temperature in the uppermost underthrust sediments (~400 mbsf). No coring planned; if time permits will core 320-410 mbsf.

Logging and Downhole: No downhole logging is planned at this site.

Nature of Rock Anticipated: Deformed claystones and hemipelagics
