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 ... -
The effects of wildfire on the water chemistry of dilute, acidic lakes in southern Norway
(Journal article; Peer reviewed, 2014)Changes in lake water chemistry were studied for >4 years following a large wildfire in a boreal forest area in Mykland, southern Norway, an area characterized by thin and patchy, base-poor and slow-weathering soils and ... -
The Flow of IWRM in SADC: The Role of Regional Dynamics, Advocacy Networks and External Actors
(Journal article; Peer reviewed, 2016)This article explores the entry and spread of IWRM in the Southern African Development Community (SADC) region. It traces how the idea of IWRM was pro moted and sustained throughout the region by mapping key events, actors ... -
The future Dutch Environment and Planning Act in light of the ecosystem approach
(Journal article; Peer reviewed, 2018)This paper discusses whether the future Dutch Environment and Planning Act has embraced the ecosystem approach as a leading paradigm. -
The impact of an abandoned mercury mine on the environment in the Xiushan region, Chongqing, southwestern China
(Journal article; Peer reviewed, 2018)Mercury contamination is a serious problem in the Hg mining area of Xiushan County, Chongqing, southwestern China. The concentrations of total mercury (THg) and methylmercury (MeHg) in paddy soil, surface water, and rice ... -
The importance of year-to-year variation in meteorological and runoff forcing for water quality of a temperate, dimictic lake
(Journal article; Peer reviewed, 2015)Natural stochasticity can pose challenges in managing the quality of the environment, or hinder understanding of the system structure. It is problematic because unfavourable stochastic events cancel management efforts and ... -
The influence of a submerged meadow on uptake and trophic transfer of legacy mercury from contaminated sediment in the food web in a brackish Norwegian fjord
(Journal article; Peer reviewed, 2019)There are contradicting results on the importance of legacy mercury (Hg) contaminated sediments to Hg fish tissue concentrations. Still, sediment remediation actions often aim at minimizing ecosystem exposure and human ... -
The influence of permanently submerged macrophytes on sediment mercury distribution, mobility and methylation potential in a brackish Norwegian fjord
(Journal article; Peer reviewed, 2018)Macrophytes are shown to affect the microbial activity in different aqueous environments, with an altering of the sediment cycling of mercury (Hg) as a potential effect. Here, we investigated how a meadow with permanently ... -
