Add-on data catalog

Quantarctica can be better if more data are added. Following datasets are developed in accordance with "how to make Quantarctica-friendy datasets". These datasets are easy to be imported to Quantarctica and, in most cases, include style settings (QLR file) as well. We apprecaite all data controbutors to make their data in a Quantarctica-frinedly manner, and wish that many people will follow them. You can find all instructions in the manual, and if you have any further questions please contact us at quantarctica@npolar.no.

Weddell Sea 1 km ice thickness and bed topography

Jeofry et al., 2018 [Publication link] [Data link]

We present a new ice thickness digital elevation model (DEM) of the Weddell Sea sector, West Antarctica. The DEM consists a total area of ~125,000 km2 covering the Institute, Möller and Foundation ice streams and the Bungenstock Ice Rise with a 1 km spatial resolution. Ice thickness DEM was formed from the available radio-echo sounding (RES) data using the 'Topo to Raster' function in ArcGIS. The RES data used in this study were compiled from four main sources which are (1) Scott Polar Research Institute (SPRI) survey collected during several campaigns in the 1970s (Drewry, 1983), (2) British Antarctic Survey (BAS) airborne radar survey conducted during the austal summer 2006/07 (GRADES/IMAGE) (Ashmore et al., 2014), (3) BAS airborne survey accomplished during the Institute and Möller Antarctic Funding Initiative (IMAFI) in 2010/2011 (Ross et al., 2012) and (4) Center for the Remote Sensing of Ice Sheet (CReSIS) data during the NASA Operation IceBridge (OIB) programme in 2012, 2014 and 2016 (Gogineni, 2012). The ice thickness picks were gridded at a uniform 1-km spacing using the Nearest Neighbour interpolation within the Topo to Raster.
