PurposeResearch
ObjectivesJR228 is a combined science and logistics leg of the 2009‐10 voyage of the RRS James Clark Ross to the Antarctic. All of the science team had participated in the previous JR230 cruise in and around Marguerite Bay on the west Antarctic Peninsula. As a result mobilisation for the cruise had mainly taken place at Rothera as part of the JR230 cruise. As part of the logistics element of JR228, the ship undertook base reliefs at Signy (South Orkney Islands) and at Bird Island and King Edward Point (South Georgia). During the science part of the cruise we undertook the Western Core Box survey to determine the distribution and biomass of krill northwest of South Georgia, and refurbished the 3 biological moorings in the South Georgia region. In addition we undertook an abbreviated acoustic survey on the shelf to the south west of South Georgia and deployed a Continuous Plankton Recorder (CPR) on the long run between Signy and South Georgia. The cruise leg terminated in Stanley.
