BODC Cruise Metadata Report for RRS Challenger (74CH) cruise CH125A

Introduction

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

Cruise Inventory Information

Long name RRS Challenger (74CH) cruise CH125A
Short name CH125A
Objectives and Narrative Recovery and redeployment of the mooring array.
After these mooring deployment, searches and attempted recoveries, including dragging, will be made for 'lost' moorings. The highest priorities are:
1) The BPRs deployed at S1500 on Charles Darwin 91 and at N1500 on Charles Darwin 93.
2) Two S200 moorings (deployed on Charles Darwin 93 and Challenger 121A) located acoustically at 56 15'N 9 10.08'W, with ranges of 1.9 and 2.5km.
3) The S140 mooring deployed on Charles Darwin 93 located acoustically at the N140 site.
Seabed photographs will be taken near the STABLE S200 site with a bed-hopping camera.
