Cruise Inventory Information
| Long name | RRS James Clark Ross (74JC) cruise JR20080221 (JR179) |
|---|---|
| Short name | JR20080221 (JR179) |
| Objectives and Narrative |
On cruise JR179 a multidisciplinary programme was carried out in the Amundsen and Bellingshausen Seas, including benthic marine biological studies and marine geological and geophysical investigations. RRS James Clark Ross became the first UK vessel to reach Pine Island Bay, and also ventured further west the ever before. In view of the large amount of passage required to reach some of the remote study sites it was clear that many days of ship time could be saved by combining different activities into a single multidisciplinary cruise. The different science teams worked well together and some interesting discussions resulted.
The data and samples collected on the cruise will provide new insights into the distribution and diversity of benthic marine fauna on the Pacific margin of Antarctica, the stability (or instability) of the West Antarctic Ice Sheet during the late Quaternary, and variations in palaeoclimatic and palaeoceanographic conditions in the region during the Holocene. The work carried out on the cruise will contribute to several International Polar Year programmes. |
