Marine biodiversity is under pressure from different anthropogenic sources, and resource- and conservation management needs information on the spatial and temporal distribution of marine animals. Such information about seabirds has been scarce, but new technology has now enabled tracking of a wide range of seabird species. In this project we will use this technology to map non-breeding habitat use and migration of seabirds from Svalbard and North Norway. Our work will be linked to a network of field sites in the Arctic and Sub-arctic, which enable multi-colony comparisons and a large-scale perspective over several years. First, by uncovering the spatial and temporal distribution we can better understand the environmental factors and anthropogenic threats (e.g. climate change, pollution, fisheries) seabirds are exposed to. Second, we may better understand how sensitive are migration and distribution to climate change, and consequently assess different seabirds’ ability to respond to climate change. A crucial point, with high relevance for conservation management, is to get several years of tracking data to evaluate whether long-distance migrants have consistent or flexible migratory strategies. Here we apply for funding for the second year of the project period 2018-2010.
