资源简介：
Cruise JR04 occupied 48 days from 3 February 1993 to 23 March 1993, to
and from Port Stanley, Falkland Islands.
The main objectives of the cruise were:
1. Coring in the Falkland Trough, Central Scotia Sea and NW Weddell
Sea, to study glacial/interglacial circulation changes.
2. Marine geophysical investigation of the Bellingshausen Sea basin
around Peter I Island.
3. Dredging along the axis of Bransfield Strait, for geochemical
analysis
A total of 110m of core was recovered from 29 stations, which should
reveal the variation of Antarctic Circumpolar Current flow through the
last glacial cycle.
The Bellingshausen Sea study collected 1520km of high quality
multichannel seismic profile, plus a greater amount of magnetic and
gravity data also some single channel seismic data.
