Position: 45°23.5'N; 44°45.5'W
Water Depth: 4563 m
Sediment Thickness: 2180 m, from stacking and wide-angle velocity models
Target Drilling Depth: 2280 mbsf
Approved Maximum Penetration: 2600 mbsf; drill without coring to 800 mbsf
Seismic Coverage: Ewing 00-07 line 2 MCS; SP 28486 (CMP 228893) (see Figs. F3, F5, F7)
Operational Program: Same as at proposed Site NNB-01A, but with a three-casing string. See "Alternate Sites: Proposed Site NNB-01B" section and Table T2.
Logging and Downhole: Three logging runs (1) triple combo tool string, (2) FMS-sonic tool string, and (3) checkshot with WST. Core orientation and temperature tools if alternate plan for shallow coring occurs.
Nature of Rock Anticipated: From top to base: clays, silty clays, and claystones (equivalent to Blake Ridge formation); siliceous and/or cherty claystones (equivalent to Bermuda Rise formation); multicolored claysontes (equivalent to Hatteras formation); possible limestone beds (?Blake-Bahama formation).
