Cruise Inventory Information
| Long name | RRS James Clark Ross (74JC) cruise JR20051226 (JR151) |
|---|---|
| Short name | JR20051226 (JR151) |
| Objectives and Narrative | The purpose of cruise JR151 was to deploy three moorings across Orkney Passage, to monitor the outflow of Weddell Sea Deep Water from the Weddell Sea into the Scotia Sea. BAS had entered an agreement with Lamont-Doherty Earth Observatory of Columbia University to cooperate on these moorings, in which we were to retrieve an LDEO mooring, M4, from Orkney Passage, refurbish the instruments, download the data, and then redeploy the instruments on the new moorings, extending from the middle of Orkney Passage and onto the slope towards the west. One day of ship time was allocated to this work. This planning was all made under the assumption that Orkney Passage would be ice free. However, at the time of the cruise, late December 2005, the whole area south and east of the South Orkneys was filled with ice, largely multiyear, that had blown up from the Weddell Sea, making Orkney Passage inaccessible within the allocated time for the cruise. A decision was therefore made to go to the area north of Coronation Island instead, and to do a CTD survey of the slope here, and, if moorings were deemed useful in this location, two moorings could be deployed here. The ship entered a lead around 7:00 on 26/12/2005, and was able to proceed to the first CTD station at around 4000 m depth at 08:37. Three more CTDs were taken at around 3500, 3000, and 2500 m depth along a course of 200°. Based on the preliminary processing of these CTDs, two moorings were deployed at approx. 4000 and 3500 m depth. These moorings are referred to as CI1 and CI2, respectively. The mooring deployments were completed at midnight on 27/12/2005, and after verifying that the mooring had landed on the seabed and the acoustic release was communicating with the deck unit, the ship proceeded toward Bird Island to commence JR140. |
