Introduction

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

Cruise Inventory Information

Long name RRS Challenger (74CH) cruise CH81
Short name CH81
Objectives and Narrative 1. To collect CTD profiles and large-volume water samples at standard positions between the Sound of Mull and the shelf-edge west of Barra for radiocaesium studies.
2. To service the DML current meter mooring in the Tiree Passage.
3. To work the CTD stations of the Anton Dohrn Seamount (Ellett Line) section, between the shelf-edge and Rockall, to continue the Rockall Trough time-series as a UK contribution to WOCE Goal 3.
4. To work the Rockall - Malin Head CTD section for further investigation of recent water mass changes west of Britain.
5. To collect Craib cores for microbiological enrichment studies at 3-4 sites.
6. To work shelf CTD sections in the Sea of the Hebrides and North Channel as time permits.
7. To collect wave data for POL using the ship's radar.
