It is occupied annually to detect changes in the Antarctic Circumpolar Current (ACC) and variability of the ocean transport. The standard section includes measurements of the physical properties of the ocean, i.e. temperature, salinity and currents. The Drake Passage section lies on a satellite ground track with the northern end on the south side of Burdwood Bank, south of the Falkland Islands, and the southern end off Elephant Island at the tip of the Antarctic Peninsula. The data have been collected in months between November and February, since 1993 (with the exception of 1995/96 and 1998/99). Measurements were taken using conductivity temperature depth (CTD) profilers and Acoustic Doppler Current Profilers (ADCPs). The Drake Passage provides the link between the Pacific and Atlantic Oceans, as it constricts the ACC to a narrow geographical region, which makes this the best place to measure its properties. The Drake Passage is a series of sustained observations which are taken to identify small changes in the ACC. The work was initially led by scientists from the Institute of Oceanographic Sciences at Wormley, and more recently by teams from the National Oceanography Centre at Southampton. The main partners have been from NERC's British Antarctic Survey. Data, from the section, are held at the British Oceanographic Data Centre.", "includedInDataCatalog": { "@id": "http://portal.medin.org.uk/portal/json-ld/catalog.jsonld" }, "conditionsOfAccess": [ "access: No limitations apply", "access: Data are freely available for teaching and research, providing due acknowledgment in any publication produced, following agreement to the terms and conditions of the British Oceanographic Data Centre Data Licence.
