(Peer reviewed; Journal article, 2017)This study was conducted to simultaneously investigate the spatial and temporal dynamics of diatom communities inhabiting two microhabitat types (Sphagnum periphyton and epipelon) in a peatland area of the Czech Republic. ... -
TEOTIL Metals: Development report - 2021
(NIVA-rapport;7569, Research report, 2021)The model TEOTIL has been widely used in Norway for simulating nutrient fluxes at national scale. This report describes extending TEOTIL to incorporate metals. A review of metal behaviours is presented and the requirements ... -
Terrengkalking som alternativ til silikatdosering i Litleåna, Lygna i Vest-Agder
(NIVA-rapport;6837, Research report, 2015)Laksevassdraget Lygnas sidevassdrag Litleåna har vært avgiftet med silikatlut (vannglass) siden 2011. Basert på en del tekniske utfordringer og ikke minst høye priser på silikatlut, vil man vurdere om terrengkalking kan ... -
Terrestrial Inputs Drive Seasonality in Organic Matter and Nutrient Biogeochemistry in a High Arctic Fjord System (Isfjorden, Svalbard)
(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 govern spatial distribution of polychlorinated biphenyls (PCBs) and hexachlorobenzene (HCB) in an Arctic fjord system (Isfjorden, Svalbard)
(Peer reviewed; Journal article, 2021)Considerable amounts of previously deposited persistent organic pollutants (POPs) are stored in the Arctic cryosphere. Transport of freshwater and terrestrial material to the Arctic Ocean is increasing due to ongoing climate ... -
Terrestrial Inputs Shape Coastal Bacterial and Archaeal Communities in a High Arctic Fjord (Isfjorden, Svalbard)
(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 ... -
Terrestrial organic matter increases zooplankton methylmercury accumulation in a brown-water boreal lake
(Journal article; Peer reviewed, 2019)Increases in terrestrial organic matter (tOM) transport from catchments to boreal lakes can affect methylmercury (MeHg) accumulation in aquatic biota both directly by increasing concentrations of aqueous MeHg, and indirectly ... -
The 'trickle down' of IWRM: A case study of local-level realities in the Inkomati Water Management Area, South Africa
(Journal article; Peer reviewed, 2016)The historical legacy in South Africa of apartheid and the resulting discriminatory policies and power imbalances are critical to understanding how water is managed and allocated, and how people participate in designated ... -
The abundance of kelp is modified by the combined impact of depth, waves and currents
(Journal article; Peer reviewed, 2019)This study analyses the combined impact of two types of ocean water flow, wave exposure and ocean currents, on kelp Laminaria hyperborea abundance, taking other environmental co-variables into account. The dataset covers ... -
The advective origin of an under-ice spring bloom in the Arctic Ocean using multiple observational platforms
(Journal article; Peer reviewed, 2018)Under-ice blooms of phytoplankton in the Chukchi Sea have been observed, with strong implications for our understanding of the production regimes in the Arctic Ocean. Using a combination of satellite remote sensing of ... -
The distribution of the Mussel Mytilus species along the Norwegian coast
(Journal article; Peer reviewed, 2013)Mussels (Mytilus spp.) are used frequently in biological effects studies and biomonitoring programs either as transplanted groups or native populations. However, as a result of the similarities in the external morphology ... -
The Effect of Extraction Methodology on the Recovery and Distribution of Naphthenic Acids of oilfield Produced Water
(Journal article; Peer reviewed, 2019)Comprehensive chemical characterization of naphthenic acids (NAs) in oilfield produced water is a challenging task due to sample complexity. The recovery of NAs from produced water, and the corresponding distribution of ... -
The Effect of Optical Properties on Secchi Depth and Implications for Eutrophication Management
(Journal article; Peer reviewed, 2019)Successful management of coastal environments requires reliable monitoring methods and indicators. Besides Chlorophyll-a concentration (Chl-a), water transparency measured as Secchi Depth (ZSD) is widely used in Baltic Sea ... -
