Further work and plans for 2017

The participants in the ArcticBiomass network have published three new articles in 2016, and we will still publish a few in 2017. The most of them are published in the Focus Issue, Focus on Recent, Present and Future Arctic and Boreal Productivity and Biomass Changes in IOP Environmental Research Letters.

Altogether, 19 articles have been published so far in this Focus Issue and there are still manuscripts that are under revision.

We have also applied for a new workshop in Svalbard which will, if funded, be arranged in August 2017.

The main purpose is 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. 

A sub-objective is to 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. This will provide a bench market to measure improvements in remote sensing based plant biomass and productivity mapping and monitoring. 

Of particular interest are areas where there has not been a positive NDVI trend. There are various explanations for this, including drought and increased winter perturbation, but there has not been an overall study of the relationship between potential stress factors and non-increasing NDVI trends. 
 
A key question is whether areas with a positive trend will experience declines in NDVI due to increased frequency of perturbations in the next decades.

To achieve the main aim of the project the work will be carried out in different work packages. 

The ArcticBiomass project will continue the mapping of vegetation and extraction of vegetation parameters in already established research regions. 

At general level the project will establishment of a joint American-Norwegian research team dealing with research on the combination of field and satellite remote sensing based plant biomass and plant productivity mapping in northern Alaska and in Svalbard, as well as on a circumpolar scale. The project will perform exchange of remote sensing data, climatic data and field data, arrange workshops and joint field campaigns on Svalbard (Ny-Ålesund and Nordenskiøldland) and in Alaska, and promote exchange of students and researchers.
