The dataset comprises a derived freshwater flux field for the Southern Ocean. This flux field is the rate of freshwater (m^-3 s^-1) entering each point of a grid covering the Southern Ocean, divided by the surface area (m^-2) represented by each grid point, which gives a flux (m s^-1) at each grid point. It was produced using up-to-date freshwater data from ice shelves, icebergs, and rivers over the period 2010-2015 and integrated over a surface encompassing Antarctica and surrounding waters. These data are intended for use in the Southern Ocean State Estimate (SOSE) iteration of the MIT General Circulation Model (MITgcm), but can be adapted for use on a different grid or model. The flux data are in units of m yr-1, on a 2160x320 grid. MATLAB scripts and tables of runoff data are available and show how the field was produced, how the data can be used and how different data can produce the field for a different grid. The field was created to update the accuracy of the freshwater input to a model based on SOSE, and to stabilise it with respect to the formation of open-ocean polynyas. This field was produced by Mark Hammond under the supervision of Dr Dan Jones at the British Antarctic Survey.

This dataset comprises a time series of measurements of water current, temperature, conductivity, and pressure from instruments deployed at various depths in the Orkney Passage from 2007 onwards. The instruments were deployed in sub surface oceanographic moorings at fixed locations, in order to monitor the transport of Weddell Sea Deep Water (ESDW), a precursor to Antarctic Bottom Water (AABW), flowing northward from the Weddell Sea into the Scotia Sea. For 2007-2011 data are typically at hourly resolution; in subsequent years, most instruments are sampling at 10 minutes' resolution. The moorings are deployed in water depths ranging between approx. 1750 and 3670 metres, with instrument depths between 1250 and 3660 metres. This time series originally started out as part of the British Antarctic Survey's Long-Term Monitoring and Survey (LTMS) programme, led by Keith Nicholls; from 2016 it is continuing as part of the Ocean Regulation of Climate by Heat and Carbon Sequestration and Transports (ORCHESTRA) project, led by Emily Shuckburgh (British Antarctic Survey) and Dynamics of the Orkney Passage Outflow (DyNOPO) led by Alberto Naveira Garabato (National Oceanography Centre). Additional support for mooring instrumentation has come from NOAA through their Ocean Climate Observation Program, Weddell Sea Moorings project, PI's Bruce Huber and Arnold Gordon, Lamont-Doherty Earth Observatory, Columbia University. The mooring work is currently led and coordinated by Povl Abrahamsen at the British Antarctic Survey. The data are subject to a two year organisational moratorium from collection after which they become publically available.

The Western Core Box dataset comprises measurements of physical oceanographic parameters and complementary meteorological data collected as part of the British Antarctic Survey Long Term and Monitoring Survey Program. Data collection covers the sea area around South Georgia Island and spans from 2006 to the present day. Data collection has a roughly annual frequency and is done through hydrographic surveys with a Conductivity-Temperature-Depth (CTD) and via the ships' underway monitoring system. Measurements include water temperature, conductivity, photosynthetically active radiation (PAR), transmittance, fluorescence and oxygen concentrations, as well as air temperature, humidity, atmospheric pressure, total incidence radiation (TIR), wind speed and direction. The Western Core Box survey has been implemented to measure the change and variability in the Earth system and monitoring of long-term processes. It also provides valuable information on the status of the marine ecosystem in this area. All data are collected by the British Antarctic Survey. The data are subject to a two year organisational moratorium from collection after which they become publicaly available.

This dataset consists of physical oceanographic and meteorological data collected in the South Orkney Islands, Southern Ocean, onboard the RRS James Clark Ross during the period of 25 February 2016 until 25 March 2016 on JR15005 a South Orkney State of the Antarctic Ecosystem (SO-AntEco) cruise. Measurements were taken using conductivity-temperature-depth (CTD) profilers with attached auxiliary sensors, expendable bathythermographs (XBTs) and the ships underway monitoring system. Hydrographic profiles provide measurements of the water column, temperature, salinity, depth, conductivity, transmittance, fluorescence, irradiance, altimetry and dissolved oxygen. Underway measurements include meteorological, surface hydrography and navigational data. The data have been collected as part of the SO-AntEco project, a British Antarctic Survey (BAS) funded programme from 20 August 2015 to 24 August 2016 lead by Dr Huw Griffiths (BAS). This involved international collaboration with scientists from BAS, Scientific Committee for Antarctic Research (SCAR), Universities (Bristol, Hull, Liverpool and Oxford) and the Natural History Museum (NHM), London. This project was part of the wider SCAR biological research programme - State of the Antarctic Ecosystem (AntEco). The British Oceanographic Data Centre (BODC) hold CTD, XBT, navigation, meteorological and surface hydrographic data. The Polar Data Centre (PDC) at BAS are responsible for the long-term management of other datasets collected on cruise JR15005.
