Cruise Inventory Information
| Long name | RRS Challenger (74CH) cruise CH3/83 |
|---|---|
| Short name | CH3/83 |
| Objectives and Narrative |
The objectives of this cruise were:
(1) To re-lay the SMBA mooring at site M (57 deg 18 min N, 10 deg 23 min W) and service mooring F (57.5N, 12.25W). Accomplished. (2) To recover the CONSLEX moorings from four sections across the Hebridean Slope. Accomplished. (3) To work the four CONSLEX CTD sections. One of the four sections worked. (4) To make Agassiz trawl hauls plus other benthos sampling in the vicinity of mooring M. Not possible. (5) To deploy a UCNW mooring at 56 deg 11 min N, 7W and service the mooring at 57 deg 26 min N, 6 deg 58 min W. Mooring deployed, but no time for service. (6) To grapple for missing moorings at station R (57N, 9W) and Y (56 deg 37 min N, 6 deg 25 min W) and re-lay Y if possible. Y partially recovered. (7) To collect large-volume samples for radiocaesium analysis with CTD profiles on stations across the Scottish shelf from the Sound of Mull. Water samples collected, but only one CTD profile possible. |
