Introduction

This report collates information from the BODC cruise inventory and oceanographic databases. It presents

Cruise Inventory Information

Long name RRS Challenger (74CH) cruise CH2/81
Short name CH2/81
Objectives and Narrative The objectives of this cruise were:
(1) To service current meter moorings at stations M, (deep water: 57 deg 18 min N, 10 deg 23 min W) and R (shelf: 57N, 9W) and re-lay the mooring at F (deep water: 57.5N, 12.25W. Mooring at R recovered and re-laid: mooring at M recovered: no work at F.
(2) To work the DML Rockall via Anton Dohrn Seamount (Ellett Line) CTD section and other sections across the Rockall Channel. Stations R (shelf) to M (deep water between the slope and the seamount) of the primary section worked plus a section across the shelf west of South Uist.
(3) To deploy a corrosion potential current meter mooring off South Uist. Accomplished.
(4) To collect large-volume surface water samples for radiocaesium analysis, accompanied by CTD profiles, at stations across the Scottish continental shelf. Accomplished with CTD profiles at all but one station.
