BODC Cruise Metadata Report for RRS Challenger (74CH) cruise CH120

Introduction

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

Cruise Inventory Information

Long name RRS Challenger (74CH) cruise CH120
Short name CH120
Objectives and Narrative 1) To service the DML LOIS Shelf Edge Study (SES) current mooring Y in the Tiree Passage.
2) To work the Anton Dohrn to Rockall Seamount CTD/nutrient/chlorophyll section (Ellett Line).
3) To recover the DML WOCE current meter mooring at station M (57 deg 18' N, 10 deg 23' W). This was not achieved.
4) To work CTD and water sampling sections along the SES lines N and S.
5) To measure rates of nitrogen fixation in the euphotic zone west of Scotland.
6) To collect large water samples over the shelf for Cs and Th isotope analysis.
7) To recover SES moorings from the shelf and slope regions.
8) To obtain multi-cores, gravity cores and box cores at SES stations S700, R1000, N1500 and N2000.
9) To trawl with an Agassiz trawl at deep and slope stations.
10) To obtain epibenthic sledge samples at station M in the Rockall Trough.
