Processed airborne radio-echo sounding data from the GRADES-IMAGE survey covering the Evans and Rutford Ice Streams, and ice rises in the Ronne Ice Shelf, West Antarctica (2006/2007)

Hugh Corr
An airborne radar survey was flown as part of the GRADES-IMAGE project funded by BAS over the Antarctic Peninsula, Ellsworth Mountains and Filchner-Ronne Ice Shelf (also including the Evans Ice stream and Carson Inlet) mainly to image englacial layers and bedrock topography during the 2006/07 field season. Operating from temporary field camps at Sky Blu, Partiot Hills and out of RABID depot (Rutford Ice Stream), we collected ~27,550 km of airborne radio-echo sounding data over...

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...

Gridded bathymetric compilation of Tristan da Cunha from multibeam echosounder data collected by multiple vessels (1996-2019)

Alice Fremand, Alison Pettafor, Daniel Evans, Floyd Howard, Simon Morley & James Bell
We present a new gridded bathymetric compilation around Tristan da Cunha here defined by the following bounding box: 5 to 16.8W, 33 to 43.5S. This bathymetry grid was compiled from a variety of multibeam swath bathymetry data acquired during 7 different cruises (see lineage). The data is available as a grid of 0.001 degrees resolution in three different formats: NetCDF, ArcView ASCII and GeoTIFF formats using geographic coordinates on the WGS84 datum. This grid is...

Coastal change data for the Antarctic Peninsula region, 1843 to 2008

Alison Cook, Adrian Fox & Janet Thomson
The dataset records ice coast and ice shelf front positions and hence change for the period 1843 to 2008. Archival maps, aerial photographs and satellite images of the Antarctic Peninsula were used to reveal the past shape of the ice coastline. The coastlines were mapped in a GIS (ESRI Arc/Info) using a mosaic of Landsat TM imagery as a common reference. Over 2000 aerial photographs and over 100 satellite images were used to compile the...

Population size and breeding success of Southern giant petrels (Macronectes giganteus), at Signy Island, South Orkney Islands, 1996 to 2019

Michael Dunn, Stacey Adlard, Amanda Lynnes, Dirk Briggs, Derren Fox & Richard Philips
The colony size and breeding success of Southern giant petrels (Macronectus giganteus) on Signy Island has been monitored annually since 1996. The data presented here includes the number of breeding pairs (occupied nests) and the number of chicks present in their nests prior to fledging. Breeding pairs and chicks are monitored by direct counts at nine sites on the west coast of the island. The nest surveys are undertaken from December to January, with chick...

Macrobenthic Mollusca from Prince Gustav Channel and Duse Bay, Eastern Antarctic Peninsula collected by epibenthic sledge in March 2018

Katrin Linse & Madeline Anderson
In 2018 RRS James Clark Ross investigated the marine benthic biodiversity of the Prince Gustav Channel area and the macrobenthic molluscan fauna collected by epibenthic sledge (EBS) has been assessed for species richness, abundance and assemblage composition as well as for functional traits. In total 20,307 mollusc specimens assigned to 50 morphospecies and 4 classes (Solenogastres, Bivalvia, Gastropoda and Scaphopoda) were identified. Assemblage analyses across the Prince Gustav Channel area did not show apparent pattern...

Data supplement to: Defratyka et al (2021); Ethane measurement by Picarro CRDS G2201-i in laboratory and field conditions: potential and limitations. https://doi.org/10.5194/amt-2020-410

Ethane can be used as a tracer gas to distinguish methane sources, both at the local and global scale. Currently, ethane can be successfully measured using flasks or dedicated in-situ analyzers. In our study, we consider the possibility of using the CRDS Picarro G2201-i instrument, dedicated to isotopic CH4 and CO2, for suitable measurements of ethane:methane ratio in mobile field, near-source conditions. Our work was divided into three steps. First, laboratory tests were run to...

Polarimetric ApRES data on a profile across Dome C, East Antarctica, 2013-2014

Hugh Corr, Catherine Ritz & Carlos Martin
The radar data collected in 2013-2014 at Dome C, East Antarctica, aims to understand bulk preferred crystal orientation fabric near a dome. We measure changes in englacial birefringence and anisotropic scattering in 21 sites along a 36 km long profile across Dome C. These optical properties are obtained by analysing radar returns for different antenna orientations. More details can be found in Ershadi et al, 2021. Funding was provided by BAS National Capability and IPEV...

Feeding activity in shallow water marine benthos at Ryder Bay, Antarctica, 1997-2005

Andrew Clarke, Helen Peat, Alice Chapman, Jennifer Beaumont, Raynor Piper, Andrew Miller & Paul Mann
Measures of feeding activity in 17 species of shallow water marine benthos, as assessed visually by SCUBA divers. The aim of the study was to determine the seasonal and interannual variability in feeding activity. Data were taken once or twice a month over the period from October 1997 to May 2005. Not all species were monitored for the entire duration of the study, and the number of observations per species ranged from 21 to 133.

Forecasts, neural networks, and results from the paper: 'Seasonal Arctic sea ice forecasting with probabilistic deep learning'

Tom R. Andersson & J. Scott Hosking
This dataset encompasses data produced in the study 'Seasonal Arctic sea ice forecasting with probabilistic deep learning', published in Nature Communications. The study introduces a new Arctic sea ice forecasting AI system, IceNet, which predicts monthly-averaged sea ice probability (SIP; probability of sea ice concentration > 15%) up to 6 months ahead at 25 km resolution. The study demonstrated IceNet's superior seasonal forecasting skill over a state-of-the-art physics-based sea ice forecasting system, ECMWF SEAS5, and...
