Spatial patterns and key drivers of zooplankton in the north central Indian Ocean
(Peer reviewed; Journal article, 2021)Zooplankton is a vital component in the pelagic marine ecosystems, linking lower to higher trophic levels. A survey was conducted with R/V Dr. Fridtjof Nansen in Sri Lankan waters in summer 2018 to explore zooplankton ... -
Spatial patterns of the temporal dynamics of three gadoid species along the Norwegian Skagerrak coast
(Journal article; Peer reviewed, 1997-08-28)Time series from an extensive research survey of juveniles of cod Gadus morhua, pollack Pollachius pollachius and whiting Merlangius merlangus sampled from 1919 to 1994 at 38 stations along the Norwegian Skagerrak coast ... -
Spatial response of hard- and mixed-bottom benthic epifauna to organic enrichment from salmon aquaculture in northern Norway
(Peer reviewed; Journal article, 2021)Norwegian Atlantic salmon aquaculture is continuing to expand in northern regions dominated by hard- and mixed-bottom substrates. Such habitats contain rich benthic epifaunal communities, including sponges and other sessile ... -
Spatial scale of genetic structuring in coastal cod Gadus morhua and geographic extent of local populations
(Journal article; Peer reviewed, 2007-08-07)We estimated the spatial scale of genetically distinguishable populations of coastal Atlantic cod Gadus morhua using microsatellite DNA markers. Significant overall heterogeneity in allele frequencies was found among 5 cod ... -
Spatial scaling of population synchrony in marine fish depends on their life history
(Peer reviewed; Journal article, 2019)The synchrony of population dynamics in space has important implications for ecological processes, for example affecting the spread of diseases, spatial distributions and risk of extinction. Here, we studied the relationship ... -
Spatial shifts in spawning habitats of Arcto-Norwegian cod related to multidecadal climate oscillations and climate change
(Journal article; Peer reviewed, 2008-06-02)Arcto-Norwegian cod tend to produce strong year classes in warm years and poor year classes in cold years. This work shows that spawning intensity at various spawning sites along 1500 km of Norwegian coast is also influenced ... -
Spatial structuring in early life stage fish diversity in the Scotia Sea region of the Southern Ocean
(Peer reviewed; Journal article, 2023)The fish community of the Scotia Sea is diverse and plays key roles in Antarctic food webs and biogeochemical cycling. However, knowledge of the spatial and community structure of their early life stages is limited, ... -
Spatial variability of the plankton trophic interaction in the North Sea: a new feature after the early 1970s
(Journal article; Peer reviewed, 2011-08-24)Traditionally, marine ecosystem structure was thought to be bottom-up controlled. In recent years, a number of studies have highlighted the importance of top-down regulation. Evidence is accumulating that the type of trophic ... -
Spatially explicit estimates of stock sizes, structure and biomass of herring and blue whiting, and catch data of bluefin tuna
(Journal article; Peer reviewed, 2015) -
Spatially explicit stock assessment uncovers sequential depletion of northern shrimp stock components in the North Sea
(Others, 2023)Space is a critical component of fisheries management. Despite this, very few of the world's fish and shellfish stocks are currently assessed using methods that are spatially structured. In the Northeast Atlantic, northern ... -
Spatially structured interactions between lobsters and lobster fishers in a coastal habitat: fine-scale behaviour and survival estimated from acoustic telemetry
(Journal article; Peer reviewed, 2013-07-18)Fishing can have profound impacts on the ecology and evolution of marine populations. Understanding population-level changes ultimately depends on knowledge about individual survival and how it varies in time and space. ... -
Spatio-temporal dynamics in the dissolved nutrient waste plume from Norwegian salmon cage aquaculture
(Peer reviewed; Journal article, 2018)The aim of this study was to define the waste plume dynamics around a salmon farm in Norway. Systematic water sampling and numerical modeling were implemented to define nutrient concentrations in the upper water column at ... -

Spatio-temporal patterns in diversity of a fish assemblage along the Norwegian Skagerrak coast
(Journal article; Peer reviewed, 1999-03-17)Time series from 1953 to 1997 of 34 fish species sampled by beach seine at 69 stations along the Norwegian Skagerrak coast were analysed to describe spatial patterns of temporal variation in species richness and diversity. ... -
Spatio-temporal turnover and drivers of bentho-demersal community and food web structure in a high-latitude marine ecosystem
(Peer reviewed; Journal article, 2022)Assess the spatial and temporal turnover of bentho-demersal marine fauna by integrating ecological metrics at the community and food web levels and evaluate their main environmental and anthropogenic drivers. -
Spatiotemporal variability of barium in arctic sea-ice and seawater
(Journal article; Peer reviewed, 2018)Freshwater export from the Arctic is critical in determining the density of water at sites of North Atlantic deep water formation, which in turn influences the global flux of oceanic heat and nutrients. We need geochemical ... -
Spatiotemporal variation in climatic conditions across ecosystems
(Peer reviewed; Journal article, 2021)Environmental variation in time and space affects biological processes such as extinction risk and speed of adaptation to environmental change. The spatial structure of environmental variation may vary among ecosystems, ... -

Spawning Atlantic cod (Gadus morhua L.) exposed to noise from seismic airguns do not abandon their spawning site
(Peer reviewed; Journal article, 2022)Seismic airgun surveys may disturb and displace fish at large ranges. If such displacement causes fish to abandon spawning grounds, reproductive success could be impacted. To investigate whether airgun sound causes cod ... -
Spawning energetics and otolith microchemistry provide insights into the stock structure of bonga shad Ethmalosa fimbriata
(Journal article; Peer reviewed, 2019)The gross energy content of spawning batches and the microchemistry of sagittal otoliths in individual female bonga shad Ethmalosa fimbriata were compared between contrasting sampling sites at the Senegalese southern coast ...
