|---|---|
| Short name | JR20121114 (JR280) |
| Objectives and Narrative |
JR280 is a 16 day science cruise to the South Georgia region nested inside a combined logistic and science leg during voyage 22 of the RRS James Clark Ross. As part of the logistics element the ship undertook base reliefs at Bird Island and King Edward Point (South Georgia), and Signy (South Orkney Islands). 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, refurbished the biological moorings in the South Georgia region and deployed a new biological mooring near Signy. In addition collaborators from the Max Planck Institute in Bremen investigated the N2O emission potential of the Antarctic krill Euphausia superba.
Since 1981 BAS have undertaken cruises to determine krill biomass as part of the ongoing assessment of the status of the marine ecosystem in the region of South Georgia. This unique time series, known as the Western Core Box, is part of the Ecosystem Programme contribution to BAS national capability. It comprises an acoustic grid survey of 8 transects each of 80 km in length, together with associated net and oceanographic sampling and the calibration of the acoustic instrumentation. Net sampling to catch live krill for experiments and observations was also undertaken at night. In addition to the acoustic survey, which covers a wide area but has limited temporal coverage, there are three moorings (one in the Western Core Box, one southwest and one northwest of South Georgia) to provide a temporal context. These moorings are recovered during the cruise, refurbished and data downloaded, and then redeployed later in the cruise. |
