Position:
|
66°24.8′S, 140°25.7′E
|
Water depth (m):
|
1010
|
Target drilling depth (mbsf):
|
190
|
Approved maximum penetration (mbsf):
|
• 250 (approved by TAMU safety panels based on EPSP Dec 2005 recommendation)
• Limit penetration to Holocene drift
• Terminate when drilling encounters glacial diamict but no more than 250 mbsf
|
Survey coverage:
|
• Site survey data outlined in Proposal 638-APL2 (available at
iodp.tamu.edu/scienceops/expeditions/wilkes_land.html)
• Track map (Fig. AF1)
• Seismic profile (Fig. AF2)
|
Objective
(see text for full details):
|
Ultrahigh resolution of Holocene climate
|
Drilling, coring, and downhole measurement program:
|
See "Proposed Site ADEL-01B"
|
Anticipated lithology:
|
• 0–200 mbsf: very soft Holocene diatom ooze
• >200 mbsf: glacial diamict
