Cruise Inventory Information

Long name RRS James Clark Ross (74JC) cruise JR20140308 (JR293 Leg1, JR299 Leg1, UKD-5)
Short name JR20140308 (JR293 Leg1, JR299 Leg1, UKD-5)
Objectives and Narrative The voyage JR299 on the RRS James Clark Ross was an amalgamation of the following cruises: JR293, JR272C and JR273B. It also included a three day extension in which to turn around two Lamont-Doherty Earth Observatory (LDEO) moorings in the Weddell Sea. JR299 also represents the final voyage of the Diapycnal and Isopycnal Mixing Experiment in the Southern Ocean (DIMES) project that began in 2009. The major field work component of DIMES consisting of five voyages by US collaborators and five (and a half) UK led voyages investigating the spread of a chemical tracer dye release through Drake Passage and other observations of internal ocean mixing in the South East Pacific and Scotia Sea. Because of this JR299 is also designated DIMES UK5.

Due to logistical constraints the cruise was split into two parts. The first was a leg from the BAS Rothera base on Adelaide Island on the Antarctic Peninsula that departed on the 9th of March and proceeded north along the coastline, undertook a CTD and VMP transect of SR1b (JR293) across Drake Passage from Elephant Island to Burdwood Bank, and finished at Punta Arenas on the 24th of March. Personnel disembarked here, notably all those associated with the VMP, and the ship resupplied and refuelled.

SR1 Transect - Drake Passage Repeat Hydrography (JR293): 30 stations across Drake Passage from Elephant Island to Burdwood Bank at the same positions as occupied in previous cruises (15 of the last 18 seasons). Increased to 34 stations to achieve high resolution sampling across the SAF/PF. The VMP and tethered VMP and technicians were only available for this part of the cruise.
