Introduction

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

Cruise Inventory Information

Long name RRS Charles Darwin (74AB) cruise CD177
Short name CD177
Objectives and Narrative The goal of this cruise was to recover and redeploy some RAPID-MOC moorings near the Eastern Boundary as part of our six-month turnaround programme. Specific cruise objectives were to:
1. Recover moorings EB1 (24 microcats) and EB2 (MMP profiling from 50m to 2500m with microcats and current meters below), two principal tall eastern boundary moorings, sited on a Topex crossover point near 24N, 24W.
2. Redeploy EB1 (24 inductive microcats plus the telemetry system) and EB2 (MMP mooring).
3. Deploy EBADCP to replace the instrument deployed in April but trawled after 10days and recovered by the R/V Poseidon.
4. Deploy two URI Pressure Inverted Echo Sounders. One deployed in 1000m and one in 5000m next to the BPR lander at mooring EB1.
5. CTD stations for pre and post deployment calibrations of all mooring instrumentation.
6. Search for and if possible recover MMP mooring EB2 deployed in April 2004 and located 100km north south of Gomorra in October 2004.
