Priority: 1
Position: 3331.7255S, 12715.8565E
Water Depth: 704 m
Sediment Thickness: ‰2830 m
Approved Maximum Penetration: 550 m
Seismic Coverage: Intersection at SPs 1668.5 and 4696 on AGSO Line 169/01

Objectives: The objectives of GAB-03B are to

  1. Collect a detailed record of Paleogene-early Neogene temperate to subtropical, mid latitude sediments deposited as lowstand sediment lobes in an upper slope environment.
  2. Contribute to the upper slope component of the shelf-to-basin paleoceanographic transect.
  3. Evaluate sea-level control on Neogene facies within an upper slope setting; in particular, to evaluate stratigraphic response to eustatic oscillations by comparison with equivalent time intervals in shelf and deep oceanic settings.
  4. Determine diagenetic history and processes within Neogene upper slope facies.

Drilling Program: Double APC, XCB

Logging and Downhole Operations: Triple combo, FMS/Sonic, WST

Nature of Rock Anticipated: Nanno-foram ooze and chalk with minor wackestone (320 m); sandy calcareous mudstone (190 m)
