Work package 2: Regional risk assessment and development of guidelines
Assessments of threats to archaeological sites in the Nuuk region will be made using a desk-based environmental model that analyses existing digital data-sets in a dynamic GIS environment. The GIS model include the sensitivity for coastal erosion, fluvial erosion, periglacial processes, changes in vegetation, soil temperatures and soil moisture content. The GIS model will be linked with an updated version of the Heritage Database at The Greenlandic National Museum to locate vulnerable hotspots and to make risk assessments, which will be used as a tool to prioritize future surveys and excavations.
The impact of threats will be quantified and the likely degree, pattern and rates at which climate change may impact particular areas/sites estimated. Assessments will be made for current conditions and a selection of future climate scenarios. The results will be tested/validated using the collected data from field sites. The REMAINS concept of studying sites located along an East-West transect secure a robust validation process because sites located within very contrasting environments will be included (ex. from no to sporadic permafrost or from sparse vegetation to meter high willow).
