Cruise Inventory Information
| Long name | RRS Challenger (74CH) cruise CH13/80 |
|---|---|
| Short name | CH13/80 |
| Objectives and Narrative |
The objectives of this cruise were:
(1) To service current meter moorings on the shelf at 57N, 9W and in deep water at 57 deg 32 min N, 12 deg 17 min W. The shelf mooring was successfully recovered an redeployed, but the deep water mooring was found collapsed on the sea-bed and left to await dragging at a later date. (2) To work the western half of the Rockall via Anton Dohrn seamount CTD section. No time available. (3) To work E-W CTD sections on the shelf from St Kilda southwards with water sampling for oxygen and nutrients. One section to the west of South Uist worked. (4) To measure chlorophyll concentration over the continental shelf and shelf-edge. Continuous along-track measurements were made with bottle samples at the CTD stations. (5) To collect large volume surface water samples for radiocaesium analysis at standard stations across the Scottish shelf. Accomplished with CTD profiles on two of the ten sites. (6) To tow standard and fast plankton recorders for comparative tests. Accomplished. |
