PurposeResearch
ObjectivesCruise JR 177 was conducted within the Scotia Sea, Southern Ocean. Three transects were run as follows:
1. from Port Stanley (Falkland Islands) to the ice edge, close to South Orkneys Islands,
2. from the ice edge to the Polar Front, north of South Georgia, and
3. from South Georgia to Port Stanley. A few days were spent in the vicinity of South Georgia before undertaking transect 3

There were nine main sampling stations along transect 2. Supplementary sampling was carried out at 2 further stations, 1 on transect 1 and 1 in the vicinity of South Georgia. The time spent at each station varied between 1 and 4 days depending on scheduled activities, which was a mixture of CTD, netting, acoustic surveying and mooring deployments. At each station we took samples and measurements to characterise the oceanography, micro- and macronutrients, phytoplankton, zooplankton, krill and myctophid fish. Observations for higher predators were maintained for the majority of daytime hours throughout the cruise. Moorings were recovered and redeployed at 2 stations and contained oceanographic and acoustic instruments and a sediment trap. Whale acoustic buoys were deployed at a supplementary station in vicinity of South Georgia

The sampling was undertaken as part of the DISCOVERY 2010 BAS programme, with its remit to investigate and describe the response of the Southern Ocean ecosystem to climate variability, climate change and commercial exploitation.
