SITE SUMMARIES

Site: 1040R-D

Priority: 2
Position: 9°39.85'N, 86°10.95'W
Water Depth: 4125 mbsf
Sediment Thickness: 660 m
Target Drilling Depth: 410 mbsf
Approved Maximum Penetration: NOT YET APPROVED BY PPSP. WOULD REQUIRE SEISMIC SURVEY AND PPSP REVIEW AND APPROVAL BEFORE OCCUPYING.
Seismic Coverage: Position of site ~500 m NW of Site 1040 projected onto shotpoint 3130 on seismic line BGR-99-44 (C. Ranero, pers. comm., GEOMAR, Kiel, Germany and C. Reichert, pers. comm., BGR, Hannover, Germany, 2001).



Objectives: The objectives of Site 1040R are to:

1. Investigate the décollement.

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

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



Drilling Program: Core with RCB from ~180 to 410 mbsf. Install modified CORK for monitoring fluid flow, pressure, and temperature in the uppermost underthrust sediments.


Logging and Downhole: Formation temperature measurements (~5 DVTP); no downhole logging is planned at this site.


Nature of Rock Anticipated: Deformed claystones and hemipelagics
