Seasonal and spatial variations in biomarker baseline levels within Arctic populations of mussels (Mytilus spp.)
(Journal article; Peer reviewed, 2019)Climate change and pollution resulting from human activities in the Arctic require reliable monitoring systems in sentinel species. Mytilus spp. are used as sentinel species all around the world. The use of Mytilus spp. ... -
Seasonal and year-to-year variation of mercury concentration in perch (Perca fluviatilis) in boreal lakes
(Journal article; Peer reviewed, 2014)The authors examined the seasonal and year‐to‐year variations of mercury (Hg) concentrations in populations of perch (Perca fluviatilis) from 2 boreal freshwater lakes in southeast Norway. Fish Hg concentrations were ... -
Seasonal diversity and dynamics of haptophytes in the Skagerrak, Norway, explored by high-throughput sequencing
(Journal article, 2015)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 ... -
Seasonal forecasting of lake water quality and algal bloom risk using a continuous Gaussian Bayesian network
(Peer reviewed; Journal article, 2022)Freshwater management is challenging, and advance warning that poor water quality was likely, a season ahead, could allow for preventative measures to be put in place. To this end, we developed a Bayesian network (BN) for ... -
Seasonal pollutant levels in littoral high-Arctic amphipods in relation to food sources and terrestrial run-off
(Peer reviewed; Journal article, 2022)Increasing terrestrial run-off from melting glaciers and thawing permafrost to Arctic coastal areas is expected to facilitate re-mobilization of stored legacy persistent organic pollutants (POPs) and mercury (Hg), potentially ... -
Seasonal rainfall affects occurrence of organohalogen contaminants in tropical marine fishes and prawns from Zanzibar, Tanzania
(Peer reviewed; Journal article, 2021)Seasonal differences in precipitation may affect contaminant dynamics in tropical coastal regions due to terrestrial runoff of contaminants to the marine environment after the rainy seasons. To assess the effect of seasonal ... -
Seasonal riverine inputs may affect diet and mercury bioaccumulation in Arctic coastal zooplankton
(Peer reviewed; Journal article, 2023)Climate change driven increases in permafrost thaw and terrestrial runoff are expected to facilitate the mobilization and transport of mercury (Hg) from catchment soils to coastal areas in the Arctic, potentially increasing ... -
Seasonal turnover in community composition of stream-associated macroinvertebrates inferred from freshwater environmental DNA metabarcoding
(Peer reviewed; Journal article, 2021)Macroinvertebrate communities are crucial for biodiversity monitoring and assessment of ecological status in stream ecosystems. However, traditional monitoring approaches require intensive sampling and rely on invasive ... -
Seasonal Variability of the Carbonate System and Air–Sea CO2 Flux in the Outer Changjiang Estuary, East China Sea
(Peer reviewed; Journal article, 2022)Three field surveys were conducted in the outer Changjiang Estuary on the inner shelf of the East China Sea in March, July, and October, 2018. Observations of total-scale pH (pHT), total alkalinity (AT), and calculated ... -
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 ... -
Seasonal variation of mercury and δ15N in fish from Lake Heddalsvatn, southern Norway
(Peer reviewed; Journal article, 2014)Seasonal variations of mercury (Hg) concentration in muscle tissue of northern pike (Esox lucius L), European whitefish (Coregonus lavaretus L) and European perch (Perca fluviatilis L) have been investigated in Lake ... -
Seasonality in land–ocean connectivity and local processes control sediment bacterial community structure and function in a High Arctic tidal flat
(Peer reviewed; Journal article, 2023)Climate change is altering patterns of precipitation, cryosphere thaw, and land–ocean influxes, affecting understudied Arctic estuarine tidal flats. These transitional zones between terrestrial and marine systems are ... -
Seaweed forests are carbon sinks that may help mitigate CO2 emissions: a comment on Gallagher et al. (2022)
(Peer reviewed; Journal article, 2023)Recently, Gallagher et al. (2022) suggested that seaweed ecosystems are net heterotrophic carbon sources due to CO2 released from the consumption of external subsidies. Here we outline several flaws in their argument, which ... -
Secchi depth in the Oslofjord-Skagerrak area: theory, experiments and relationships to other quantities
(Journal article; Peer reviewed, 2014)The Secchi depth and its relationships to other properties of the sea water in the Oslofjord–Skagerrak area have been investigated. White and black disks of different sizes have been applied, and the Secchi depth has been ... -
Sediment toxicity assessment using zebrafish (Danio rerio) as a model system: Historical review, research gaps and trends
(Peer reviewed; Journal article, 2021)Sediment is an important compartment in aquatic environments and acts as a sink for environmental pollutants. Sediment toxicity tests have been suggested as critical components in environmental risk assessment. Since the ... -
Selection of indicator contaminants of emerging concern when reusing reclaimed water for irrigation — A proposed methodology
(Peer reviewed; Journal article, 2023)Organic and microbial contaminants of emerging concern (CECs), even though not yet regulated, are of great concern in reclaimed water reuse projects. Due to the large number of CECs and their different characteristics, it ... -
Selection of the optimal extraction protocol to investigate the interaction between trace elements and environmental plastic
(Peer reviewed; Journal article, 2023)The interaction between environmental plastic and trace elements is an issue of concern. Understanding their interaction mechanisms is key to evaluate the potential threats for the environment. To this regard, consolidating ... -
Self Adjusting Algorithm for the Nontargeted Feature Detection of High Resolution Mass Spectrometry Coupled with Liquid Chromatography Profile Data
(Journal article; Peer reviewed, 2019)Nontargeted feature detection in data from high resolution mass spectrometry is a challenging task, due to the complex and noisy nature of data sets. Numerous feature detection and preprocessing strategies have been developed ... -
Self-reports of consumption of amphetamines, cocaine and heroin in a survey among marginalized drug users
