    • Choose your poison – Space-use strategy influences pollutant exposure in Barents Sea polar bears 

      Tartu, Sabrina; Aars, Jon; Andersen, Magnus; Polder, Anuschka; Bourgeon, Sophie; Merkel, Benjamin; Lowther, Andrew D.; Bytingsvik, Jenny; Welker, Jeffrey Martin; Derocher, Andrew E.; Jenssen, Bjørn Munro; Routti, Heli (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-01-24)
      Variation in space-use is common within mammal populations. In polar bears, Ursus maritimus, some individuals follow the sea ice (offshore bears) whereas others remain nearshore yearlong (coastal bears). We studied pollutant exposure in relation to space-use patterns (offshore vs coastal) in adult female polar bears from the Barents Sea equipped with satellite collars (2000–2014, n = 152). First, ...

    • Drones and marine mammals in Svalbard, Norway 

      Palomino-González, Albert; Kovacs, Kit M.; Lydersen, Christian; Ims, Rolf Anker; Lowther, Andrew D. (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-03-14)
      The impact of remotely piloted aircraft systems (RPAS) on marine mammals remains poorly documented despite their increasing use. In the high-Arctic Archipelago of Svalbard, where marine mammals face increasing pressure from climate change and expanding tourism, the use of RPAS remains largely unregulated. In this study we assessed the impacts of RPAS across a range of species to provide ...

    • Harbour seal Phoca vitulina movement patterns in the high-Arctic archipelago of Svalbard, Norway 

      Blanchet, Marie-Anne Ermeline; Lydersen, Christian; Ims, Rolf Anker; Lowther, Andrew D.; Kovacs, Kit (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 ...

(Journal article; Tidsskriftartikkel; Peer reviewed, 2020-03-18)
      The Retrospective Analysis of Antarctic Tracking Data (RAATD) is a Scientific Committee for Antarctic Research project led jointly by the Expert Groups on Birds and Marine Mammals and Antarctic Biodiversity Informatics, and endorsed by the Commission for the Conservation of Antarctic Marine Living Resources. RAATD consolidated tracking data for multiple species of Antarctic meso- and top-predators ...
