    • Swimming performance of subarctic Calanus spp. facing downward currents 

      Weidberg, Nicholas; DiBacco, Claudio; Pezzola, Caterina; Rebiffe, Etienne; Basedow, Sünnje Linnéa (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-04-29)
      Calanoid copepods dominate mesozooplankton communities in temperate and Nordic seas. The ability of copepods to remain and feed in productive surface waters depends on their ability to overcome downward flows. In this study, we assessed the swimming performance of subarctic Calanus spp. and tested how the copepods can retain their vertical position in a representative range of downward currents ...

    • Temporal dynamics in zooplankton δ13C and δ15N isoscapes for the North Atlantic Ocean: Decadal cycles, seasonality, and implications for predator ecology 

      Espinasse, Boris Dristan; Sturbois, Anthony; Basedow, Sünnje Linnéa; Hélaouët, Pierre; Johns, David G.; Newton, Jason; Trueman, Clive N. (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-10-17)
      The limited amount of ecological data covering offshore parts of the ocean impedes our ability to understand and anticipate the impact of anthropogenic stressors on pelagic marine ecosystems. Isoscapes, i.e., spatial models of the distribution of stable isotope ratios, have been employed in the recent years to investigate spatio-temporal patterns in biogeochemical process and ecological responses. ...

    • Transport Barriers and the Retention of Calanus finmarchicus on the Lofoten Shelf in Early Spring 

      Dong, Huizi; Zhou, Meng; Hu, Ziyuan; Zhang, Zhaoru; Zhong, Yisen; Basedow, Sünnje Linnéa; Smith Jr., Walker O. (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-08-02)
      Large aggregations of the copepod Calanus finmarchicus occur each spring in the shelf-slope-oceanic regions off the Lofoten-Vesterålen Islands where productive fisheries have traditionally supported local economies. The retention and off-shelf transport of populations of C. finmarchicus populations were studied by analyzing ocean color remote sensing, satellite altimetry data, and Lagrangian Coherent ...

    • Trophic positions of mesozooplankton across the North Atlantic: estimates derived from biovolume spectrum theories and stable isotope analyses theories and stable isotope analyses 

      Basedow, Sünnje Linnéa; da Silva, Nuwan Alexandrio Lawrence; Bode, Antonio; van Beusekorn, Justus (Journal article; Tidsskriftartikkel; Peer reviewed, 2016-10-03)
      The structure of marine pelagic food webs determines the fate of organic carbon and productivity, but it is difficult to measure. We compared two common methods (stable isotope analyses, SIAs, and biovolume spectrum theories, BSTs) of estimating trophic positions (TPs) of mesozooplankton. Two sets of stations across the North Atlantic (Iceland Basin, Irminger Basin, Labrador Sea) were clearly ...

    • Water column distribution of zooplanktonic size classes derived from in-situ plankton profilers: Potential use to contextualize contaminant loads in plankton 

      Espinasse, Boris Dristan; Pagano, M.; Basedow, Sünnje Linnéa; Chevalier, C.; Malengros, D.; Carlotti, F. (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-09-29)
      Pollution is one of the main anthropogenic threats to marine ecosystems. Studies analysing the accumulation and transfer of contaminants in planktonic food webs tend to rely on samples collected in discrete water bodies. Here, we assessed the representativeness of measurements at the chlorophyll-a maximum layer during the MERITEHIPPOCAMPE cruise for the entire water column by investigating the ...
