      Effective ocean management requires integrated and sustainable ocean observing systems enabling us to map and understand ecosystem properties and the effects of human activities. Autonomous subsurface and surface vehicles, here collectively referred to as “gliders”, are part of such ocean observing systems providing high spatiotemporal resolution. In this paper, we present some of the results achieved ...

    • Mid-summer vertical behavior of a high-latitude oceanic zooplankton community 

      Bandara, Kanchana; Basedow, Sünnje Linnéa; Pedersen, Geir; Tverberg, Vigdis (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-03-18)
      Vertical behavior, such as diel vertical migration (DVM) and swarming are widespread among zooplankton. At higher latitudes, synchronized DVM is mostly absent during summer and predominantly herbivorous copepods tend to form large near-surface swarms. This behavior is risky because it can make them vulnerable to visual predators. Here, we used ca. 12 days of mid-summer (28 June to 10 July 2018) ...

    • Seasonal vertical strategies in a high-Arctic coastal zooplankton community 

      Bandara, Kanchana; Varpe, Øystein; Søreide, Janne; Wallenschus, Jago; Berge, Jørgen; Eiane, Ketil (Journal article; Tidsskriftartikkel; Peer reviewed, 2016-08-18)
      We studied the larger (>1000 µm) size fraction of zooplankton in an Arctic coastal water community in Billefjorden, Svalbard (78°40’ N), Norway, in order to describe seasonal vertical distributions of the dominant taxa in relation to environmental variability. Calanus spp. numerically dominated the herbivores; Aglantha digitale, Mertensia ovum, Beroë cucumis, and Parasagitta elegans were the ...

    • Two hundred years of zooplankton vertical migration research 

      Bandara, Kanchana; Varpe, Øystein; Wijewardene, Lishani; Tverberg, Vigdis; Eiane, Ketil (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-05-04)
      Vertical migration is a geographically and taxonomically widespread behaviour among zooplankton that spans across diel and seasonal timescales. The shorter-term diel vertical migration (DVM) has a periodicity of up to 1 day and was first described by the French naturalist Georges Cuvier in 1817. In 1888, the German marine biologist Carl Chun described the longer-term seasonal vertical migration ...
