During the austral summer of 2005/06 a collaborative UK/Italian field campaign collected ~61,000 line km of aerogeophysical data over the previously poorly surveyed Wilkes subglacial basin, Dome C, Transantarctic Mountains, George V Land and Northern Victoria Land using airborne survey systems mounted in a Twin Otter aircraft. 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.

The ICEBERGS project aimed to understand the impact of retreating coastal glaciers upon benthic marine ecosystems along the West Antarctic Peninsula (WAP). This was a collaboration project between University of Exeter, the British Antarctic Survey, Universidad Catololica de Santiago de Concepcion and Bangor University. During three research cruises (JR17001, JR18003 and JR19002) between 2017 and 2020, biological specimens along with other scientific data and samples were collected from three coastal fjords (i.e. Marian Cove, Borgen Bay and Sheldon Cove). The biological samples were collected using mainly a benthic Agassiz trawl and some using a Hamon grab and they were either preserved in ethanol or dry. Funding: The funding for this grant was provided from NERC and from CONICYT Chile (NERC-CONICYT; NE/P003087/1).
