Introduction

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

Cruise Inventory Information

Long name RRS Challenger (74CH) cruise CH12/82
Short name CH12/82
Objectives and Narrative The objectives of this cruise were:
(1) To deploy current meter, pressure gauge and thermistor chain moorings along four sections across the Scottish Continental Slope between 57N and 59N. Acomplished with the exception of one mooring.
(2) To work CTD profiles along these four sections. Accomplished, but salinity data are reported as noisy due to a faulty counter.
(3) To measure bathymetric profiles along these sections. Accomplished.
(4) To service SMBA moorings at M and the Tiree Passage and recover moorings from stations P and R. Not possible due to bad weather.
(5) To collect large-volume samples for radiocaesium analysis on stations across the Scottish shelf from the Sound of Mull. Seven of ten stations sampled.
