Seasonal Cycle of Sea Surface Salinity in the Angola Upwelling System
(Peer reviewed; Journal article, 2022)The seasonal cycle of sea surface salinity (SSS) along the Angolan coast is investigated using observations and a regional ocean model. The model reproduces the main characteristic of the seasonal cycle of SSS along the ... -
Seasonal dynamics and life histories of three sympatric species of Pseudocalanus in two Svalbard fjords
(Peer reviewed; Journal article, 2021)Small copepods are the most diverse and numerous group in high-latitude zooplankton, yet our knowledge of important species remains poor because of the difficulties involved in correct species identification. In this study, ... -
Seasonal Dynamics of Atlantic Herring (Clupea harengus L.) Populations Spawning in the Vicinity of Marginal Habitats
(Journal article; Peer reviewed, 2014-11-05)Gillnet sampling and analyses of otolith shape, vertebral count and growth indicated the presence of three putative Atlantic herring (Clupea harengus L.) populations mixing together over the spawning season February–June ... -
Seasonal dynamics of carbonate chemistry, nutrients and CO2 uptake in a sub-Arctic fjord
(Peer reviewed; Journal article, 2020)Environmental change can have a significant impact on biogeochemical cycles at high latitudes and be particularly important in ecologically valuable fjord ecosystems. Seasonality in biogeochemical cycling in a sub-Arctic ... -
Seasonal dynamics of spatial distributions and overlap between Northeast Arctic cod (Gadus morhua) and capelin (Mallotus villosus) in the Barents Sea
(Journal article; Peer reviewed, 2018)The trophic link between cod (Gadus sp.) and capelin (Mallotus sp.) is important in many panarctic ecosystems. Since the early 2000s, the Northeast Arctic cod stock (G. morhua) in the Barents Sea has increased greatly, and ... -
Seasonal dynamics of the marine CO2 system in Adventfjorden, a West Spitsbergen fjord
(Journal article; Peer reviewed, 2019)Time series of the marine CO2 system and related parameters at the IsA Station, by Adventfjorden, Svalbard, were investigated between March 2015 and November 2017. The physical and biogeochemical processes that govern ... -
Seasonal ecology in ice-covered Arctic seas - Considerations for spill response decision making
(Peer reviewed; Journal article, 2018)Due to retreating sea ice and predictions of undiscovered oil and gas resources, increased activity in Arctic shelf sea areas associated with shipping and oil and gas exploration is expected. Such activities may accidentally ... -
Seasonal Patterns of Sporophyte Growth, Fertility, Fouling, and Mortality of Saccharina latissima in Skagerrak, Norway: Implications for Forest Recovery
(Journal article; Peer reviewed, 2011-07-10)On the Skagerrak coast the kelp Saccharina latissima has suffered severe stand reductions over the last decade, resulting in loss of important habitats. In the present study, healthy kelp plants were transplanted into four ... -
Seasonal patterns of vertical flux in the northwestern Barents Sea under Atlantic Water influence and sea-ice decline
(Peer reviewed; Journal article, 2023)The northern Barents Sea is a productive Arctic inflow shelf with a seasonal ice cover and as such, a location with an efficient downward export of particulate organic matter through the biological carbon pump. The region ... -
Seasonal phytoplankton blooms in the North Atlantic linked to the overwintering strategies of copepods
(Journal article; Peer reviewed, 2016)The North Atlantic Ocean contains diverse patterns of seasonal phytoplankton blooms with distinct internal dynamics. We analyzed blooms using remotely-sensed chlorophyll a concentration data and change point statistics. ... -
Seasonal plankton dynamics along a cross-shelf gradient
(Journal article; Peer reviewed, 2006-08-08)Much interest has recently been devoted to reconstructing the dynamic structure of ecological systems on the basis of time-series data. Using 10 years of monthly data on phyto- and zooplankton abundance from the Bay of ... -
Seasonal plankton dynamics in Kongsfjorden during two years of contrasting environmental conditions
(Peer reviewed; Journal article, 2023)Seasonal plankton time-series data are presented from Kongsfjorden from two years with contrasting environmental conditions. Kongsfjorden (west coast of Spitsbergen – 79°N) integrates inputs from Atlantic and Arctic waters, ... -
Seasonal temperature regulates network connectivity of salmon louse
(Peer reviewed; Journal article, 2022)Chronically high infestation of salmon louse (Lepeophtheirus salmonis) questions the sustainability of the Norwegian Atlantic salmon (Salmo salar) aquaculture industry. The confinement of millions of hosts, within hundreds ... -
Seasonal variability in nutrient regeneration by mussel Mytilus edulis rope culture in oligotrophic systems
(Journal article; Peer reviewed, 2011-06-09)Blue mussel Mytilus edulis cultures contribute to nutrient cycling in coastal ecosystems. Mussel populations filter particulate nutrients from the water column and inorganic nutrients are regenerated by excretion of metabolic ... -
Seasonal Variability in the Zooplankton Community Structure in a Sub-Arctic Fjord as Revealed by Morphological and Molecular Approaches
(Peer reviewed; Journal article, 2021)Phyto- and zooplankton in Arctic and sub-Arctic seas show very strong seasonal changes in diversity and biomass. Here we document the seasonal variability in the mesozooplankton community structure in a sub-Arctic fjord ... -
Seasonal variation in marine C:N:P stoichiometry: can the composition of seston explain stable Redfield ratios?
(Journal article; Peer reviewed, 2011)Seston is suspended particulate organic matter, comprising a mixture of autotrophic, heterotrophic and detrital material. Despite variable proportions of these components, marine seston often exhibits relatively small ... -
