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.
