    • Cetacean presence on the northern Mid Atlantic Ridge revealed through passive acoustic monitoring 

      Dunning, Katherine; Ahonen, Heidi; Menze, Sebastian (Master thesis; Mastergradsoppgave, 2022-09-16)
      Cetaceans are known to utilise the Mid-Atlantic Ridge, a key topographical feature in the Atlantic Ocean, for migratory and feeding purposes. Passive acoustic monitoring was used over a one-year period (2007/2008) to identify cetacean vocalisations that occurred on a location near the Charlie Gibbs Fracture Zone. Using species-specific vocalisations that have previously been documented in the North ...

    • Is ambient light during the high Arctic polar night sufficient to act as a visual cue for zooplankton? 

      Cohen, Jonathan H.; Berge, Jørgen; Moline, Mark A.; Sørensen, Asgeir Johan; Last, Kim; Falk-Petersen, Stig; Renaud, Paul; Leu, Eva; Grenvald, Julie Cornelius; Cottier, Finlo; Cronin, Heather; Menze, Sebastian; Norgren, Petter; Varpe, Øystein; Daase, Malin; Darnis, Gérald; Johnsen, Geir (Journal article; Tidsskriftartikkel; Peer reviewed, 2015-06-03)
      The light regime is an ecologically important factor in pelagic habitats, influencing a range of biological processes. However, the availability and importance of light to these processes in high Arctic zooplankton communities during periods of 'complete' darkness (polar night) are poorly studied. Here we characterized the ambient light regime throughout the diel cycle during the high Arctic ...

    • Productive detours – Atlantic water inflow and acoustic backscatter in the major troughs along the Svalbard shelf 

      Menze, Sebastian; Ingvaldsen, Randi Brunvær; Nikolopoulos, Anna; Hattermann, Tore; Albretsen, Jon; Gjøsæter, Harald (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-09-30)
      Atlantic Water (AW) flowing along the western and northern Svalbard shelf-break extends the Atlantic domain into the Arctic and is the region’s major source of heat, nutrients and advected plankton. We investigated the inflow and recirculation of AW into four major troughs that cut into the Svalbard shelf, the Isfjorden, Kongsfjorden, Hinlopen and Kvitøya Troughs, and related the circulation patterns ...
