Harbour seal Phoca vitulina movement patterns in the high-Arctic archipelago of Svalbard, Norway
(Journal article; Tidsskriftartikkel; Peer reviewed, 2014-09-03)
Harbour seals Phoca vitulina are mainly considered a temperate species, but the world’s northernmost population resides year-round in the high-Arctic archipelago of Svalbard. In this study we document post-moulting at-sea movements of 30 individuals from this population using satellite relay data loggers deployed in the autumns of 2009 and 2010. All of the seals showed a strong preference for ...
Seasonal, oceanographic and atmospheric drivers of diving behaviour in a temperate seal species living in the high arctic
(Journal article; Tidsskriftartikkel; Peer reviewed, 2015-07-21)
The harbour seal (Phoca vitulina) population in Svalbard marks the northernmost limit of the species’ range. This small population experiences environmental extremes in sea and air temperatures, sea ice cover and also in light regime for this normally temperate species. This study deployed Conductivity Temperature Depth Satellite Relay Data Loggers (CTDSRDLs) on 30 adult and juvenile harbour ...
Haul-out behaviour of the world's northernmost population of harbour seals (Phoca vitulina) throughout the year

An Arctic predator–prey system in flux: climate change impacts on coastal space use by polar bears and ringed seals
(Journal article; Tidsskriftartikkel; Peer reviewed, 2017-04-17)
<p>1. Climate change is impacting different species at different rates, leading to alterations in biological interactions with ramifications for wider ecosystem functioning. Understanding these alterations can help improve predictive capacity and inform management efforts designed to mitigate against negative impacts.</p> <p>2. We investigated how the movement and space use patterns of polar bears ...
Haul-out behaviour of Arctic ringed seals (Pusa hispida): inter-annual patterns and impacts of current environmental change
(Journal article; Tidsskriftartikkel; Peer reviewed, 2018-01-27)
Hauling out onto a solid substrate is an integral part of most pinnipeds’ activity budgets. Ringed seals (<i>Pusa hispida</i>) are an Arctic species that hauls out on sea ice routinely throughout the year. In 2006, a sudden change in the sea-ice regime occurred in Svalbard (Norway). Amongst other changes, the amount of land-fast ice declined sharply. This study examined the intra- and inter-annual ...
Habitats and movement patterns of white whales Delphinapterus leucas in Svalbard, Norway in a changing climate
(Journal article; Tidsskriftartikkel; Peer reviewed, 2018-10-24)
Background: The Arctic is experiencing rapid reductions in sea ice and in some areas tidal glaciers are melting and retracting onto land. These changes are occurring at extremely rapid rates in the Northeast Atlantic Arctic. The aim of this study was to investigate the impacts of these environmental changes on space use by white whales (Delphinapterus leucas) in Svalbard, Norway. Using a unique ...
