Final Workshop

ArcticBiomass Final Workshop, 20-23 October 2015 Longyearbyen

""

Background: ArcticBiomass is a Norway-USA network project funded by the Research Council of Norway. The objectives of this project are to:

  • Establish a joint American-Norwegian research team dealing with research on the combination of field and satellite remote sensing based above-ground plant biomass,vegetation productivity and growing season mapping in northern Alaska and in Svalbard, as well as on a circumpolar scale.
  • Compile existing plant biomass and productivity data from the North Slope of Alaska and from Svalbard, and to evaluate existing remote sensing data and remote sensing based biomass products throughout the Arctic.

Workshop themes: phenology, climate and productivity, biomass estimation and monitoring from plot scale to satellite.
