Priority: 1 (Alternate to BT-4)
Position: 24°33.34'N; 79°22.05'W
Water Depth: 680 m
Sediment Thickness: >8000 m
Total Penetration: 732 mbsf (approved to a depth of 932 mbsf)
Seismic Coverage: High-resolution MCS survey
Objectives: The objectives of BT-41 are to:
1. obtain a record of the facies of the basinal deposits associated with the prograding sequence, and
2. assess and date the deposition and erosional gaps associated with the Florida Current.
Hole A: APC/XCB to a depth refusal or a depth of 732 of mbsf.
Hole B: APC to refusal.
Hole C: RCB to 732 m, if target depth not reached by XCB and only if time permits.
Logging and downhole: ADARA heatflow measurements will be made on the first eight APC cores below Core 3 and one every third core thereafter. WSTP will be performed on every fifth XCB core. The hole will be logged using the three standard logging strings (Quad-Combination, GLT), FMS).
Nature of rock anticipated: Periplatform ooze occasionally mixed with coarser grained units.
