The goal of this initiative is to develop a digital data base that contains all available bathymetric data north of 64 degrees -200 North, for use by mapmakers, researchers, and others whose work requires a detailed and acurate knowledge of the depth and the shape of the Arctic seabed. Initiated in 1997, this undertaking has so far engaged the volunteer efforts of investigators who are affiliated with -250 eleven institutions in eight countries: Canada, Denmark, Germany, Iceland, Norway, Russia, Quest Channel Quest B Sweden, and the USA. The activity has also been endorsed and/or supported financially by Lena Trough -300 the Intergovernmental Oceanographic Commission (IOC), the International Arctic Science 80Ê Kvitùyra Committee (IASC), the International Hydrographic Organization (IHO), the US Office of Naval 80Ê A Research (ONR), and the US National Geophysical Data Center (NGDC).

Based on data from R/V Polarstern multibeam sonar surveys between 1984 and 1997 we produced a high resolution bathymetry Spitsbergen Trough* -500 Y of the central Fram Strait. The area insonified covers approx. 36,500 km2 between 78oN - 80 o o o Norske Bank N and 0 E - 7.5 E. Basic outcome of the investigation is a raster Digital Terrain Model -1000 M (DTM) with 100 m grid spacing. Martin Klenke, Alfred Wegener Institute for Polar and Marine GUSTAV V Research 2003.

GSHHS is a high-resolution shoreline data set amalgamated from two data bases in the Freemansundet ISFJORDEN SABINE LAND -5500 public domain. The data have undergone extensive processing and are free of internal inconsistencies such as erratic points and crossing segments. The shorelines are constructed entirely from hierarchically arranged closed polygons. The data can be used to NORDENSKIOLD LAND -6500 simplify data searches and data selections, or to study the statistical characteristics of Isfjord Bank shorelines and land-masses. It comes with access software and routines to facilitate STORFJORDEN Edgeùya decimation based on a standard line-reduction algorithm. http://www.ngdc.noaa.gov/mgg/shorelines/gshhs.html NATHORST LAND VAN MIJENFJORDEN VAN KEULENF.

The setting up of SCUFN arose from the need for a uniform policy for the handling of geographical names and standardization of undersea feature names, in order to achieve consisten naming on Knipovich Ridge bathymetric maps and nautical charts. All names selected by SCUFN are contained in the GEBCO Gazetteer of Undersea Feature Names. The most recent Gazetteer is that of Storfjord Channel December 2002. http://www.ngdc.noaa.gov/mgg/gebco/underseafeatures.html Fram Strait feature names: 75Ê 75Ê These names marked with * have been proposed in April 2003 by Alfred Wegener Institute for Polar and Marine Research and accepted by SCUFN.
