Cruise Inventory Information

Long name RRS James Clark Ross (74JC) cruise JR20141115 (JR304)
Short name JR20141115 (JR304)
Objectives and Narrative JR304 was a 19 day science cruise to the South Georgia region nested inside a combined logistic and science leg during voyage 24 of the RRS James Clark Ross. As part of the logistics element the ship undertook base reliefs at Signy (South Orkney Islands), and 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, refurbished the biological moorings in the South Georgia region and carried out a series of time stations across the Scotia Sea. BAS scientists were joined by collaborators from Sir Hardy Foundation for Ocean Science (SAHFOS), National Oceanography Centre (NOC) in addition to PhD students from the DTP's EnvEast, Spitfire and GW4+.

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 covered a wide area but had limited temporal coverage, there were three moorings (one in the Western Core Box, one southwest and one northwest of South Georgia) to provide a temporal context. These moorings were recovered during the cruise, refurbished and data downloaded, then redeployed later in the cruise.
