The Norwegian River Monitoring Programme 2023 – water quality status and trends
Kaste, Øyvind; Gundersen, Cathrine Brecke; Sample, James Edward; Mcgovern, Maeve; Skancke, Liv Bente; Allan, Ian; Jenssen, Marthe Torunn Solhaug; Bæk, Kine; Skogan, Odd Arne Segtnan (NIVA-rapport;8007-2024, Research report, 2024)Twenty rivers along the Norwegian coast are monitored for physical and chemical parameters as part of the Norwegian River Monitoring Programme. This report presents the current status (2023) and long-term (1990-2023) trends ... -
Seasonal pollutant levels in littoral high-Arctic amphipods in relation to food sources and terrestrial run-off
Skogsberg, Stina Linnea Emelie; Mcgovern, Maeve; Poste, Amanda; Jonsson, Sofi; Arts, Michael T.; Varpe, Øystein; Borgå, Katrine (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 riverine inputs may affect diet and mercury bioaccumulation in Arctic coastal zooplankton
Carrasco, Nathalie; Mcgovern, Maeve; Evenset, Anita; Søreide, Janne E.; Arts, Michael T.; Jonsson, Sofi; Poste, Amanda Elizabeth (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 ... -
Seasonality in land–ocean connectivity and local processes control sediment bacterial community structure and function in a High Arctic tidal flat
Handler, Eleanor R.; Andersen, Sebastian; Gradinger, Rolf Rudolf; Mcgovern, Maeve; Vader, Anna; Poste, Amanda Elizabeth (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 ... -
Small Arctic rivers transport legacy contaminants from thawing catchments to coastal areas in Kongsfjorden, Svalbard
Mcgovern, Maeve; Borgå, Katrine; Heimstad, Eldbjørg Sofie; Ruus, Anders; Christensen, Guttorm; Evenset, Anita (Peer reviewed; Journal article, 2022)Decades of atmospheric and oceanic long-range transport from lower latitudes have resulted in deposition and storage of persistent organic pollutants (POPs) in Arctic regions. With increased temperatures, melting glaciers ... -
Strong macrobenthic community differentiation among sub-Arctic deep fjords on small spatial scales
Kokarev, Valentin; Tachon, Mathieu; Austad, Marthe; Mcgovern, Maeve; Reiss, Henning (Peer reviewed; Journal article, 2021)Fjords play an important role in carbon cycling and sequestration, but the burial of organic matter in sediments strongly depends on the composition of macrobenthic communities. We studied three deep, sub-Arctic fjords ... -
Terrestrial Inputs Drive Seasonality in Organic Matter and Nutrient Biogeochemistry in a High Arctic Fjord System (Isfjorden, Svalbard)
Mcgovern, Maeve; Pavlov, Alexey K.; Deininger, Anne; Granskog, Mats; Leu, Eva Susanne; Søreide, Janne; Poste, Amanda (Peer reviewed; Journal article, 2020)Climate-change driven increases in temperature and precipitation are leading to increased discharge of freshwater and terrestrial material to Arctic coastal ecosystems. These inputs bring sediments, nutrients and organic ... -
Terrestrial Inputs Shape Coastal Bacterial and Archaeal Communities in a High Arctic Fjord (Isfjorden, Svalbard)
Delpech, Lisa-Marie; Vonnahme, Tobias; Mcgovern, Maeve; Gradinger, Rolf; Præbel, Kim; Poste, Amanda (Peer reviewed; Journal article, 2021)The Arctic is experiencing dramatic changes including increases in precipitation, glacial melt, and permafrost thaw, resulting in increasing freshwater runoff to coastal waters. During the melt season, terrestrial runoff ... -
Three decades of change in the Skagerrak coastal ecosystem, shaped by eutrophication and coastal darkening
