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. |
