Cruise Inventory Information

Long name RRS Challenger (74CH) cruise CH7A/82
Short name CH7A/82
Objectives and Narrative The objectives of this cruise were:
(1) To service or deploy current meter moorings on 6 SMBA stations, including the long-term stations F, M and R. Four stations turned around, one (F) recovered but not re-laid.
(2) To deploy and IOS Bidston tide gauge at 57 deg 20 min N, 9 deg 54 min W. Accomplished.
(3) To work the Rockall via Anton Dohrn Seamount (Ellett Line) and other CTD sections. Worked as far as station F (between the seamount and Rockall).
(4) To recover fouling mooring from west of South Uist. Not done due to weather.
(5) To collect large-volume water samples for radiocaesium analysis with CTD profiles on stations. Accomplished.
(6) To measure chlorophyll concentrations on the shelf and over the shelf edge. Accomplished by bottle profiles and continuous underway fluorometer.
(7) To work CTD sections in the Sea of the Hebrides. No time available.
