PurposeResearch
ObjectivesJR274 was conducted within the Scotia Sea and Weddell Sea in the Atlantic Sector of the Southern Ocean. The transects were run as follows
1. Falkland Islands to Elephant Island (following the NOC Drake's Passage transect)
2. Elephant Island to South Orkneys (in three transects heading NE and SE)
3. South Orkneys to NW South Georgia (following the DISCOVERY 2010 transect and beyond the Polar Front)
4. South Georgia to South Sandwich Islands (initially heading E and then SE)
5. South Sandwich Islands to Weddell Sea
6. Weddell Sea to South Georgia
7. South Georgia to Falkland Islands.

A total of 48 sampling stations were undertaken, while samples were also taken between every 2 and 4 hours en route from the underway non toxic pumped sea water supply. The sampling stations were mainly to sample the carbonate chemistry system and the accompanying biotic communities (microplankton, phytoplankton and zooplankton). Carbon and carbonate chemistry was also measured as well as trace metals and trace gasses. The majority of measurements were limited to the upper 300 m of the water column although there were 5 full depth CTD deployments during Legs 5 and 6.

The sampling was carried out as part of the UK Ocean Acidification Sea Surface Consortium with a remit to investigate the influence pH and carbonate chemistry on pelagic communities and upper ocean chemical processes.
