Atmospheric deposition effects on plankton communities in the Eastern Mediterranean: A mesocosm experimental approach
(Peer reviewed; Journal article, 2017-07-04)The effects of atmospheric deposition on plankton community structure were examined during a mesocosm experiment using water from the Cretan Sea (Eastern Mediterranean), an area with a high frequency of atmospheric aerosol ... -
Centennial decline in North Sea water clarity causes strong delay in phytoplankton bloom timing
(Peer reviewed; Journal article, 2019-08-23)With climate warming, a widespread expectation is that events in spring, such as flowering, bird migrations, and insect bursts, will occur earlier because of increasing temperature. At high latitudes, increased ocean ... -
Drivers of spatial variability in spring bloom onset and magnitude along a latitudinal gradient in the Nordic Seas
(Master thesis, 2018-06-21)Spring phytoplankton blooms in the Nordic Seas contribute a large proportion of global primary production, and their timing and magnitude heavily impacts higher trophic levels. Two key drivers of bloom development, ... -
Ice-algal carbon supports harp and ringed seal diets in the European Arctic: evidence from fatty acid and stable isotope markers
(Journal article; Peer reviewed, 2021)Sea-ice declines in the European Arctic have led to substantial changes in marine food webs. To better understand the biological implications of these changes, we quantified the contributions of ice-associated and pelagic ... -
Microbial winter and spring bloom dynamics in a high Arctic fjord
(Master thesis, 2014-06-02)Knowledge of the seasonal dynamics within the Arctic marine microbial network is scarce, particularly during the polar night period. The abundances of different microbial groups in Adventfjorden, Svalbard were investigated ... -
Phenology and Environmental Control of Phytoplankton Blooms in the Kong Håkon VII Hav in the Southern Ocean
(Journal article; Peer reviewed, 2021)Knowing the magnitude and timing of pelagic primary production is important for ecosystem and carbon sequestration studies, in addition to providing basic understanding of phytoplankton functioning. In this study we use ... -
Scaling laws in phytoplankton nutrient uptake affinity
(Peer reviewed; Journal article, 2016-03-11)Nutrient uptake affinity affects the competitive ability of microbial organisms at low nutrient concentrations. From the theory of diffusion limitation it follows that uptake affinity scales linearly with the cell radius. ... -
Seasonal diversity and dynamics of haptophytes in the Skagerrak, Norway, explored by high-throughput sequencing
(Peer reviewed; Journal article, 2015-06)Microalgae in the division Haptophyta play key roles in the marine ecosystem and in global biogeochemical processes. Despite their ecological importance, knowledge on seasonal dynamics, community composition and abundance ...
