Artificial light during the polar night disrupts Arctic fish and zooplankton behavior down to 200 m depth
Berge, Jørgen; Geoffroy, Maxime; Daase, Malin; Cottier, Finlo Robert; Priou, Pierre; Cohen, Jonathan H.; Johnsen, Geir; McKee, David; Kostakis, I; Renaud, Paul E.; Vogedes, Daniel Ludwig; Anderson, Philip J.; Last, Kim; Gauthier, Stephane (Peer reviewed; Journal article, 2020)For organisms that remain active in one of the last undisturbed and pristine dark environments on the planet—the Arctic Polar Night—the moon, stars and aurora borealis may provide important cues to guide distribution and ... -
Development of a bio-optical model for the Barents Sea to quantitatively link glider and satellite observations: A bio-optical model for the Barents Sea
Kostakis, I.; Röttgers, R.; Orkney, A.; Bouman, H.A.; Porter, M.; Cottier, Finlo Robert; Berge, Jørgen; Mckee, David (Peer reviewed; Journal article, 2020)A bio-optical model for the Barents Sea is determined from a set of in situ observations of inherent optical properties (IOPs) and associated biogeochemical analyses. The bio-optical model provides a pathway to convert ... -
Eat or sleep: Availability of winter prey explains mid-winter and spring activity in an Arctic Calanus population
Hobbs, Laura; Banas, Neil S.; Cottier, Finlo Robert; Berge, Jørgen; Daase, Malin (Peer reviewed; Journal article, 2020)Copepods of the genus Calanus have adapted to high levels of seasonality in prey availability by entering a period of hibernation during winter known as diapause, but repeated observations of active Calanus spp. have been ... -
A marine zooplankton community vertically structured by light across diel to interannual timescales
Hobbs, Laura; Banas, Neil S.; Cohen, Jonathan H.; Cottier, Finlo Robert; Berge, Jørgen; Varpe, Øystein (Journal article; Peer reviewed, 2021)The predation risk of many aquatic taxa is dominated by visually searching predators, commonly a function of ambient light. Several studies propose that changes in visual predation will become a major climate-change impact ... -
Phytoplankton community succession and dynamics using optical approaches
Fragoso, Glaucia Moreira; Johnsen, Geir; Chauton, Matilde Skogen; Cottier, Finlo Robert; Ellingsen, Ingrid H. (Peer reviewed; Journal article, 2020)The phytoplankton in coastal regions are responding to constant environmental changes, thus the use of proxies derived from in situ frequent time-series observations and validated from traditional microscopic or pigment ... -
Sensor-Carrying Platforms
Sørensen, Asgeir Johan; Ludvigsen, Martin; Norgren, Petter; Ødegård, Øyvind; Cottier, Finlo Robert (Chapter, 2020)Information and communication technology, autonomy, and miniaturization in terms of, for example, microelectromechanical systems are enabling technologies with significant impact on the development of sensors, sensor-carrying ... -
The advective origin of an under-ice spring bloom in the Arctic Ocean using multiple observational platforms
Johnsen, Geir; Norli, Marit; Moline, Mark A.; Robbins, Ian; Quillfeldt, Cecilie von; Sørensen, Kai; Cottier, Finlo Robert; Berge, Jørgen (Journal article; Peer reviewed, 2018)Under-ice blooms of phytoplankton in the Chukchi Sea have been observed, with strong implications for our understanding of the production regimes in the Arctic Ocean. Using a combination of satellite remote sensing of ... -
Zooplankton and sediment fluxes in two contrasting fjords reveal Atlantification of the Arctic
Weydmann-Zwolicka, Agata; Prątnicka, Paula; Łącka, Magdalena; Majaneva, Sanna; Cottier, Finlo Robert; Berge, Jørgen (Peer reviewed; Journal article, 2021)Svalbard fjords are facing a significant increase in Atlantic water inflow, which influences all ecosystem components, thus the objective of this study was to assess how recent Atlantification impacts the functioning of ...
