  • Medium resolution dataset of rock outcrop in Antarctica. Data have been prepared from various map and remotely sensed datasets ranging from 1960s-2019. This dataset has been generalised from the high resolution version. The large majority of data was compiled in 1993 and the quality and accuracy is uncertain. The automatically extracted rock outcrop layer provides a more accurate dataset in most locations.

  • Microclimate data collected hourly at Coal Nunatak, for 10 climatic variables via automatic data loggers, 2006-2019. Data is not available across the entire temporal range for all variables. NERC funded under the British Antarctic Survey National Capability programme, Polar Science for Planet Earth. **Please be advised to use Version 2.0 of this dataset, which has undergone additional quality control, found here:**

  • This dataset presents the relative diatom abundances of 55 species/groups from the 132-120 ka interval in marine sediment core TPC288 (-59.14 degN, -37.96 degE). This age interval corresponds to the peak of Marine Isotope Stage 5e (130- 116 ka). Microscope slides were prepared using a method adapted from Scherer (1994) and 300+ diatom valves were counted for each depth sample to produce the relative percentage abundance of each diatom species/group. This project was funded by the UK Natural Environment Research Council Grant NE/L002531/1

  • Two consecutive cruises in the Weddell Sea, Antarctica, in winter/spring 2013 provided the first direct observations of sea salt aerosol (SSA) production from blowing snow above sea ice, thereby validating a model hypothesis to account for winter time SSA maxima in polar regions not explained otherwise. Concentration, size distribution and chemical composition of airborne snow particles, sea salt aerosol and snow on sea ice where measured on board RV Polarstern as well as on the sea ice during ice stations. Funding was provided by NERC projects NE/J023051/1 and NE/J020303/1.

  • This dataset contains the annual ice front position shapefiles of the Thwaites Glacier Ice Tongue between 2000 and 2018 as shown in the Miles et al. (2020) paper. Each shapefile was mapped manually from MODIS imagery in the March of each year. The dataset details the retreat of the ice tongue and transition from a tabular calving regime to a disintegration type calving. This work was funded by NERC grant NE/R000824/1.

  • Datasets from a shallow water mooring deployed in the Southern Ocean, north of South Georgia in January 2004 during the marine cruise JR96 and recovered in March 2004 by the marine cruise JR100.

  • Datasets from a deep water mooring deployed in the Southern Ocean, north of South Georgia in April 2005 during the marine cruise JR121 and recovered in December 2005 by the marine cruise JR140.

  • Geological analyses were conducted on rock samples collected in Dronning-Maud Land during the 2007-2008 field season. Analyses included grain-size determination, dating, whole rock and inclusion mineralogy, and geochemical analyses. All of the samples taken were of rocks that were found cropping out as nunataks. The investigation took place entirely within the the Dronning-Maud Land area of East Antarctica (Norwegian Sector).

  • The number of Fur and Elephant seals around the base on Signy Island have been counted daily between January and March since 1992. Details of the area counted are given in the 1992 Seal Mammal report (AD6/2H/1992/NM3).

  • An airborne radar survey was flown over the Institute and Moller ice streams in the Weddell Sea sector of West Antarctica in the austral summer of 2010/11 as part of the Institute-Moller Antarctic Funding Initiative (IMAFI) project (grant reference number: NE/G013071/1). This project was a NERC Antarctic Funding Initiative (AFI) collaborative project between the British Antarctic Survey and the Universities of Edinburgh, York, Aberdeen and Exeter with the aim to test the hypothesis that the Institute and Moller ice streams are underlain by weak marine sediments which control the flow of the overlying ice. Operating from two static field camps close to the ice divide between the Institute and Moller ice streams and Patriot Hills, we collected ~25,000 km of airborne radio-echo sounding data across 28 survey lines. Our aircraft was equipped with dual-frequency carrier-phase GPS for navigation, radar altimeter for surface mapping, wing-tip magnetometers, a LaCoste and Romberg air-sea gravimeter, and an ice-sounding radar system (PASIN). We present here the full radar dataset consisting of the deep-sounding chirp and shallow-sounding pulse-acquired data in their processed form, as well as the navigational information of each trace, the surface and bed elevation picks, ice thickness, and calculated absolute surface and bed elevations. This dataset comes primarily in the form of NetCDF and georeferenced SEGY files. To interactively engage with this newly-published dataset, we also created segmented quicklook PDF files of the radar data.
