Nuisance growth of Juncus bulbosus: the roles of genetics and environmental drivers tested in a large-scale survey
(Journal article; Peer reviewed, 2013)1. Invasive species can transform aquatic ecosystems, and the nuisance growth of the freshwater macrophyte Juncus bulbosus has become a problem in many lakes and rivers in northern Europe. It affects biodiversity strongly ... -
Nutrient criteria for surface waters under the European Water Framework Directive: Current state-of-the-art, challenges and future outlook
(Peer reviewed; Journal article, 2019)The aim of European water policy is to achieve good ecological status in all rivers, lakes, coastal and transitional waters by 2027. Currently, more than half of water bodies are in a degraded condition and nutrient ... -
Nutrient retention by the littoral vegetation of a large lake: Can Lake Ohrid cope with current and future loading?
(Peer reviewed; Journal article, 2020)Nitrogen and phosphorus budgets were compiled for the littoral (29 km2) and pelagic (329 km2) of ancient, deep, clear, and hard water Lake Ohrid (Albania and North Macedonia), to assess the importance of the littoral in ... -

Ny kalkingsstrategi for laks i Sokndalsvassdraget
(NIVA-rapport;7145, Research report, 2017-04)Sokndalsvassdraget er et av de sørligste laksevassdragene i Norge. Det ble tidlig sterkt rammet av forsuring, og laksen var utryddet allerede i 1880-årene. Kalking ble påbegynt i 1987, og laksen har nå kommet tilbake til ... -

(NIVA-rapport;6795, Research report, 2015)Næringsnett og miljøgifter i organismer er undersøkt i Gunneklevfjorden i 2013. Det er samlet inn zooplankton, bunndyr og fisk for kjemiske analyser av kvikksølv og klorerte forbindelser. Kartlegging av næringsnettet er ... -
Observation of Floating Inorganic Macro-debris in The Downstream Citarum River using Manual Counting
(Peer reviewed; Journal article, 2022)Inorganic Macro-debris (IMD) such as plastics can negatively affect aquatic life and human wellbeing. Information about IMD transport in river systems is required to optimize prevention, mitigation, and reduction strategies. ... -
Observations of turbulence caused by a combination of tides and mean baroclinic flow over a fjord sill
(Journal article; Peer reviewed, 2015)This study investigates the dissipation rates and flow conditions at the Drøbak Sill in the Oslofjord. The area was transected 13 times with a free-falling microstructure shear probe during 4 days in June 2011. At the same ... -
Observing Temporally Varying Synoptic-Scale Total Alkalinity and Dissolved Inorganic Carbon in the Arctic Ocean
(Peer reviewed; Journal article, 2023)The long-term absorption by the oceans of atmospheric carbon dioxide is leading to the slow decline of ocean pH, a process termed ocean acidification (OA). The Arctic is a challenging region to gather enough data to examine ... -
