SPRI Time-and Position-Tagged Radio Echo Profiles for Severnaya Zemlya (SZ), 1997, plus derived Ice Thickness point data and Digital Elevation Models (DEMs)

This data set contains radar sounder echo strength profiles from the SPRI 100 MHz ice penetrating radar instrument deployed over Severnaya Zemlya (SZ), Russian Arctic, in 1997 as well as ice thickness and related products generated from these data. The data were collected during survey flights between 9 and 24 April 1997 under funding from: U.K. Natural Environment Research Council (NERC) grants GR3/9958 and GST/02/2195; EU Environment Programme grants ENV4CT97-0490 and 0426; Alfred-Wegener-Institut, Germany; and Russian Fund for Fundamental Studies. Participants from the Scott Polar Research Institute (SPRI)/Bristol Glaciology Centre were J. A. Dowdeswell, M. R. Gorman and R. P. Bassford. The project was a collaboration between UK scientists and those from Russian institutions, principally the Institute of Geography at the Russian Academy of Sciences, Moscow (Drs A.F Glazovsky and Y.Y. Macheret).

Software / Usage instructions

The following links provide access to software for reading and viewing NetCDF data files. Please be sure to review instructions on installing and running the programs. • See the NetCDF Resources at NSIDC page (nsidc.org/data/netcdf/tools.html, as at 6 Dec 2017) for tools to work with NetCDF files. • HDFView: Visual tool for browsing and editing HDF4, HDF5, and NetCDF files, available from The HDF Group (www.hdfgroup.org, as at 6th Dec 2017). • ncBrowse (www.pmel.noaa.gov/epic/java/ncBrowse/, as at 6th Dec 2017) • Panoply (www.giss.nasa.gov/tools/panoply/, as at 2 March 2020)) NetCDF files were generated from CDL text files, using utility program ncgen. In order to generate the CDL files, raw waveform data files were firstly re-formatted using a simple bespoke command-line utility to give complete waveform records on a single line of tab-delimited ASCII text each, and with Latitude and Longitude converted to decimal degrees, waveform sample values de-inverted. The original datafile name was given for each record, to ensure traceability back to original data. The intermediate ASCII text files were then converted to CDL text files using a second bespoke command-line utility. For further details of this process, see the README file (README_ArchivalSoftware_SZ) in the ArchivalSoftware folder within the archive. ESRI Shapefiles, and other coverages and grid data can be read by ESRI products such as ArcMap, and by other GIS software, such as QGIS. Excel Spreadsheet and Word documents may be read by the relevant Microsoft products, or alternatives such as OpenOffice or LibreOffice. PDF browse files can be displayed by any software capable of reading PDF format.
