Cruise Inventory Information

Long name RRS Challenger (74CH) cruise CH2/82
Short name CH2/82
Objectives and Narrative The objectives of this cruise were:
(1) To service current meter moorings at stations R (57N, 9W), M (57 deg 18 min N, 10 deg 23 min W), F (57.5N, 12.25W), A1 (52.5N, 14 deg 46 min W) and A2 (52.5 N, 14 deg 56 min W), to lay a mooring at Y (Tiree Passage: 56 deg 37 min N, 6 deg 24 min W) and deploy the corrosion potential current meter off South Uist). Moorings R and F recovered and re-laid: Tiree Passage mooring deployed.
(2) To service MAFF current meter moorings at A3 (52.5N, 15 deg 16 min W) and A4 (52.5 N, 15 deg 26 min W) and IOS Bidston pressure gauge at 56 deg 41 min N, 11 deg 32 min W). Check Bidston pressure gauge at 57 deg 10 min N, 10 deg 6 min W. No time to service A3/A4 due to poor weather. Pressure gauge destroyed in an accident during recovery. Other gauge confirmed in position.
(3) To work the Rockall via Anton Dohrn Seamount CTD section and other sections across the southern Rockall Channel. Not done due to winch problems and poor weather.
(4) To collect large-volume surface and sub-surface water samples for radiocaesium analysis with CTD profiles on stations. Surface samples at all 10 stations plus Tiree Passage site with sub-surface samples on 6. CTD profiles were possible on 4.
(5) To make Agassiz trawl and benthic sledge hauls to the east of the Anton Dohrn Seamount and at the SMBA permanent benthos station (54.5N). One sledge haul on the seamount possible producing a good catch.
(6) To work CTD sections in the Sea of the Hebrides. Not possible due to poor weather.
(7) To collect underway surface temperature and salinity samples along track. Accomplished.
