Proposed Site GOA16-2A

Priority: Alternate
Position: 58°46.3476′N, 144°30.1200′W
Water depth (mbrf): 3701
Target drilling depth (mbsf): 962
Approved maximum penetration (mbsf): 1100
Survey coverage: Inline GOA3201 (CDP 535), STEEP07 (CDP 3478), Xline STEEP13 (CDP 21728) (navigation and bathymetric maps Figs. AF12, AF13; seismic profiles Figs. AF14, AF16, AF17)
Objective: • Tectonic and climate history of upper Surveyor Fan and origin of Surveyor Fan sequence boundaries
• Provenance of unroofed sediments
Drilling and coring program: • Hole A: APC to ~200 mbsf with non-magnetic core barrels and core orientation
• Hole B: APC to ~200 mbsf with non-magnetic core barrels
• Hole C: APC to ~200 mbsf with non-magnetic core barrels
• Hole D: APC/XCB to 962 mbsf
• See “Drilling and coring strategy” and Table T3
Downhole measurements program: • Hole A: APCT-3 (SET if needed) formation temperature measurements
• Hole D: wireline logging with triple combo, FMS-sonic, VSI, and Magnetic Properties tool strings
• See “Downhole measurements strategy” and Table T3
Anticipated lithology: Mud (possibly diatom rich), silt, fine sand, volcanic ash, ice-rafted debris
