PurposeResearch
ObjectivesThe archipelago of South Georgia is a large, isolated land and continental shelf area in the Atlantic sector of the Southern Ocean. South Georgia has been identified as a key source of regional biodiversity, potentially supporting anomalously high levels of endemic and range-edge species and intense phytoplankton blooms supporting a rich food web that includes zooplankton, in particular large densities of Antarctic krill (Euphausia superba), and vertebrate predators (penguins, seals and whales). Yet the near surface waters of South Georgia are some of the fastest warming on the planet.
Since 1981 BAS have undertaken cruises to monitor Antarctic 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 series, is part of the Ecosystem Programme contribution to BAS LTMS National Capability. In addition to the acoustic survey, which covers a wide area but has limited temporal coverage, it deploys moorings in the Western Core Box and South Georgia region to complement the annual surveys by providing year round temporal sampling of environmental conditions and acoustic backscatter.
This cruise undertook the regular Western Core Box survey; an acoustic grid survey of 8 transects each 80 km in length, together with associated net and oceanographic sampling that consisted of regulare CTD and XBT deployments, continuous underway data logging and RTM8 net sampling in day and time stations. In addition, net sampling for zooplankton, micro- and nano-plastics were performed and followed up by incubation experiments. Furthermore, two long term moorings in the South Georgia region, at the P3 and WCB site, were successfully refurbished and the P2 site mooring recovered.
17 days of a science program on the vessel RRS James Clark Ross were flanked by logistics visits of the Mare Harbour, Falkland Islands, at the beginnig of the survey and the Rothera UK Antarctic Research Station at the end of the leg.
