Site summaries (continued)

Site MAL-01A

Priority: Primary
Position: 4.933109N, 73.011323E
Jurisdiction: Maldives
Water depth (m): 512
Target drilling depth (mbsf): 1060
Approved maximum penetration (mbsf): 1060
Survey coverage (track map; seismic profile): Location map (Fig. F19)
Primary line(s): Line 65 (Fig. F21)
Objective(s): 1. Provide detailed reconstruction of the predrowning, drowning, and postdrowning evolution of the carbonate bank by linking the seismic stratigraphic record to the sedimentary record
2. Constrain the timing of this evolution, allowing age assignments of unconformities, sedimentary interruptions, sedimentary turnovers, and onset of drift deposition
3. Reconstruct and date bank to drift turnover
Drilling program: Hole A: APC to 80 mbsf.
Hole B: drill/wash to 80 mbsf, RCB to 1060 mbsf
Logging and downhole measurement program: Wireline log with triple combo and FMS-sonic.
Nature of rock anticipated: Calcareous ooze, chalk, limestone
