Cruise Inventory Information

Long name	RRS Challenger (74CH) cruise CH7A/83
Short name	CH7A/83
Objectives and Narrative	The objectives of this cruise were: (1) To service current meter moorings on the Porcupine Bank Slope, at sites F and M in the Rockall Channel and site Y in the Tiree Passage. One (of 2) Porcupine Bank moorings could not be located. Otherwise accomplished. CTD section worked along Porcupine mooring line. (2) To deploy four current meter moorings on a line across the Hebridean Slope west of South Uist. Two moorings deployed. (3) To deploy three satellite-tracked drogues at the southern entrance to the Rockall Channel. Accomplished. (4) To make Agassiz trawl, benthic sledge and midwater trawl hauls at the 54N benthos station and station M. Accomplished. (5) To work CTD sections with radiochemical sampling across the Scottish continental shelf. Four sections worked between the Mull of Galloway and Islay. (6) To deploy IOS Bidston tide gauges in the Porcupine Sea Bight and the Rockall Channel. Accomplished.
