    • Accounting for Uncertainties in Biodiversity Estimations: A New Methodology and Its Application to the Mesopelagic Sound Scattering Layer of the High Arctic 

      Herrmann, Bent; Cerbule, Kristine; Brčić, Jure; Grimaldo Vela, Eduardo Enrique; Geoffroy, Maxime; Daase, Malin; Berge, Jørgen (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-04-27)
      Measures of biological diversity (biodiversity) are important for monitoring the state of ecosystems. Several indices and methods are used to describe biodiversity from field observations. Marine faunal biodiversity is often quantified based on analysis of samples collected using a trawl during research surveys. To monitor spatial and temporal changes in biodiversity between surveys, samples are ...

    • Aspects of the life history of the Atlantic poacher, Leptagonus decagonus, in Svalbard waters 

      Heggland, Kristin N.; Ottesen, Camilla; Berge, Jørgen (Journal article; Tidsskriftartikkel; Peer reviewed, 2015-03-25)
      The aim of the study is to describe aspects of the life history of the Atlantic poacher (Leptagonus decagonus) obtained during early October 2010 and late September 2011 from the Hinlopen Strait, located between Nordaustlandet and the Spitsbergen Archipelago. Length was measured for 142 individuals, and 82 out of these were weighed, sexed and the age in years determined. The sex distribution in the ...

    • Seasonal variability of meio- and macrobenthic standing stocks and diversity in an Arctic fjord (Adventfjorden, Spitsbergen) 

      Pawlowska, J.; Wlodarska-Kowalczuk, Maria; Zajaczkowski, Marek; Nygård, Henrik Andreas; Berge, Jørgen (Journal article; Tidsskriftartikkel; Peer reviewed, 2011)
      Strong environmental seasonality is a basic feature of the Arctic system, still there are few published records of the seasonal variability of the Arctic marine biota. This study examined the year-round seasonal changes of soft bottom macro- and meiobenthic standing stocks and diversity on a station located in an Arctic fjord (Adventfjorden, Spitsbergen). The seasonality observed in benthic biota ...
