Site summaries (continued)

Site MAL-06B

Priority: Alternate
Position: 4.771096N, 73.066848E
Jurisdiction: Maldives
Water depth (m): 379
Target drilling depth (mbsf): 604
Approved maximum penetration (mbsf): 604
Survey coverage (track map; seismic profile): Location map (Fig. F13)
Primary line(s): Line 59 (Fig. F15)
Objective(s): 1. Analyze cyclostratigraphy of drift deposits, providing reconstructions of changes in the current regime and monsoon cyclicity
2. Provide a detailed reconstruction of the predrowning, drowning, and postdrowning evolution of the carbonate bank by linking the seismic stratigraphic record to the sedimentary record
3. Constrain the timing of this evolution, allowing age assignments of unconformities, sedimentary interruptions, sedimentary turnovers, and onset of drift deposition
4. Reconstruct and date bank to drift turnover
Drilling program: Triple APC to 200 mbsf
Hole C: XCB to 604 mbsf
Logging and downhole measurement program: Wireline log with triple combo and FMS-sonic
Nature of rock anticipated: Calcareous ooze, chalk (drifts)
