Introduction

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

Cruise Inventory Information

Long name RRS Challenger (74CH) cruise CH105
Short name CH105
Objectives and Narrative 1. To make CTD profiles and to collect water samples for nutrient and phytoplanktonic analysis at standard positions between the Sound of Mull and the shelf edge West of Barra.
2. To maintain the DML current meter mooring in the Tiree Passage.
3. To deploy an RDI broadband acoustic Doppler profiler (ADCP) on a trial mooring prior to its eventual deployment in the Agulhas Current as part of WOCE.
4. To collect a suite of physical, biological and chemical profiles and sea-bed samples (multicorer and Craib corers) at the shelf edge as part of the LOIS studies.
5. To recover and redeploy a temperature and salinity recorder with thermistor chain at station M of the Anton Dohrn section.
6. To work the CTD stations of the Anton Dohrn Seamount (Ellett Line) section between the shelf-edge and Rockall to continue the Rockall Trough times series as a UK contribution to WOCE goal . To collect nuitrient and phytoplankton samples along this line.
7. To work CTD, nutrient and phytoplankton sections in the Clyde Sea area as a part of the MAST 2 "PROFILE" project.
8. To launch POL satellite tracked drogues in the North Channel in preparation for "Challenger" cruise 106.
9. To measure water column and sea surface conditions on the continental shelf in the swath of ERS-1 satellite overpasses on the 12th and 13th of September.
10. To collect material from the core of the Scottish Continental Slope Current, adjacent shelf waters and the Rockall Trough to study zooplankton indicator species there.
11. To collect live copepods, Plueromamma robusta (Giesbrecht, 1889).
