Priority: 1
Position: 42°54.82´S, 8°53.99´E
Water Depth: 3718 m
Sediment Thickness: 800 m
Approved Maximum Penetration: 200 m
Seismic Coverage: TN057/TSO3, shot point TN1850
Objectives: Recover a continuous Pliocene-Pleistocene composite section at moderate
sedimentation rates to study
1. past migrations in the position of the PFZ;
2. changes in the mixing ratios of lower NADW and CPDW in the Southern Ocean and its
relation to high-latitude climate change;
3. the response of the Southern Ocean to orbital forcing and the phase relationships (leads and
lags) to climatic changes in the high-latitude Northern Hemisphere;
4. the stability of the Antarctic cryosphere during "warmer-than-present" climate during the
Pliocene prior to the initiation of Northern Hemisphere glaciation;
5. the response to orbital forcing and the phase relationships of proxy records to climatic records in low and northern high latitudes.
Drilling Program: Triple APC/XCB to 200 m
Logging and Downhole: None
Nature of Rock Anticipated: Foram-nannofossil ooze
