Cruise Inventory Information
| Long name | RRS Challenger (74CH) cruise CH7/79 |
|---|---|
| Short name | CH7/79 |
| Objectives and Narrative |
The objectives of this cruise were:
(1) Service the current meter mooring at 57N, 9W and deploy moorings at three stations on the Rockall via Anton Dohrn Seamount section. Accomplished, but one recovered current meter has failed due to leakage. (2) Service IOS moorings in the Rockall Channel. Two of four moorings were recovered. (3) Work the Rockall via Anton Dohrn Seamount (Ellett Line) CTD section. Only part of the section from the seamount eastwards could be worked due to time lost through mooring recovery problems. (4) Work additional CTD sections in the northern Rockall Channel. A section across the Cirolana Deep was started but not finished due to technical problems with the CTD. (5) Collect large-volume surface water sample for radiocaesium analysis from Scottish shelf stations. Accomplished with CTD profiles on all but one station. (6) Obtain epibenthic sled samples at the SMBA permanent station (54 deg 40 min N, 12 deg 16 min W). Not possible due to poor weather and time lost through mooring recovery problems. (7) Obtain deep plankton samples at the SMBA permanent section using the rectangular mid-water trawl. Not possible due to poor weather and time lost through mooring recovery problems. (8) Obtain Assagiz trawl samples between the Anton Dohrn Seamount and the St Kilda continental slope. One good sample was obtained. |
