Hydrodynamic modelling of recreational water quality using Escherichia coli as an indicator of microbial contamination
(Journal article; Peer reviewed, 2018)Microbial contamination of recreational beaches is often at its worst after heavy rainfall events due to storm floods that carry fecal matter and other pollutants from the watershed. Similarly, overflows of untreated sewage ... -
Hydrogen sulphide dynamics in recirculating aquaculture systems with moving or fixed bed biofilters: A case study in two commercial salmon smolt producing farms in Norway
(Peer reviewed; Journal article, 2024)Sudden mass mortalities of fish reared in recirculating aquaculture systems (RAS) have occurred in recent years. High total dissolved sulphide (H2S + HS- + S2-) levels in the rearing water have been suggested as an underlaying ... -
Hydrological pulses and burning of dissolved organic carbon by stream respiration
(Journal article; Peer reviewed, 2019)Stream metabolism plays a significant role in the global carbon cycle. Storm events can lower stream metabolic activities by removing standing biomass and river bed stock of organic matter. However, hydrological events ... -

Hydropower-induced selection of behavioural traits in Atlantic salmon (Salmo salar)
(Peer reviewed; Journal article, 2021)Renewable energy projects such as hydropower facilities contribute towards meeting the world`s growing energy demands and urgent need for mitigating climate change. However, such infrastructure has the potential to ... -
Hydropower: gas supersaturation and the role of aquatic plant photosynthesis for fish health
(NIVA-rapport;7633, Research report, 2021)Fish and invertebrates breathing in water supersaturated with gas (total dissolved gas; TDG), e.g. at the outlet of hydropower plants, may develop gas bubble disease (analogous to the bends in humans). Aquatic plants also ... -
Hypoxia tolerance and responses to hypoxic stress during heart and skeletal muscle inflammation in Atlantic salmon (Salmo salar)
(Journal article; Peer reviewed, 2017)Heart and skeletal muscle inflammation (HSMI) is associated with Piscine orthoreovirus (PRV) infection and is an important disease in Atlantic salmon (Salmo salar) aquaculture. Since PRV infects erythrocytes and farmed ... -
Identification and quantification of selected plastics in biosolids by pressurized liquid extraction combined with double-shot pyrolysis gas chromatography–mass spectrometry
(Peer reviewed; Journal article, 2020)The identification and quantification of selected plastics (polystyrene (PS), polycarbonate (PC), poly-(methyl methacrylate) (PMMA), polypropylene (PP), polyethylene terephthalate (PET), polyethylene (PE) and polyvinyl ... -
Identification of 24-O-β-d-Glycosides and 7-Deoxy-Analogues of Okadaic Acid and Dinophysistoxin-1 and -2 in Extracts from Dinophysis Blooms, Dinophysis and Prorocentrum Cultures, and Shellfish in Europe, North America and Australasia
(Peer reviewed; Journal article, 2021)Two high-mass polar compounds were observed in aqueous side-fractions from the purification of okadaic acid (1) and dinophysistoxin-2 (2) from Dinophysis blooms in Spain and Norway. These were isolated and shown to be ... -
Identifikation af potentielt velegnede områder for genetablering af stenrev i de sydøstlige dele af Storebælt
(NIVA-rapport;6913, Research report, 2015)Formålet med denne rapport og de gennemførte analyser har været at udpege områder i det sydøstlige Storbælt, hvor der potentielt kan etableres stenrev. Baggrund for arbejdet har været et ønske fra Slagelse Kommune om på ... -
Identifying discontinuities of flood frequency curves
(Peer reviewed; Journal article, 2023)Discontinuities in flood frequency curves, here referred to as flood divides, hinder the estimation of rare floods. In this paper we develop an automated methodology for the detection of flood divides from observations and ... -
Ikke-hjemmehørende arter i marine områder
(NIVA-rapport;7658, Research report, 2021)Denne rapport omhandler ikke-hjemmehørende arter i de danske farvande og består af to dele. Den første vedrører en opdate-ring af den nationale liste over ikke-hjemmhørende arter i de danske farvande – også kaldet NIS-listen. ... -
Immunohistochemical localization of inflammatory cells and cell cycle proteins in the gills og Loma salmonae infected rainbow trout (Oncorhynchus mykiss)
(Journal article; Peer reviewed, 2014)Microsporidial gill diseases particularly those caused by Loma salmonae incur significant economic losses to the salmonid aquaculture industry. The gill responses to infection include the formation of xenomas and the acute ... -
Impact of an icy winter on the Pacific oyster (Crassostrea gigas Thunberg, 1793) populations in Scandinavia
