Environmental impacts of produced water and drilling waste discharges from the Norwegian offshore petroleum industry
(Journal article; Peer reviewed, 2013)Operational discharges of produced water and drill cuttings from offshore oil and gas platforms are a continuous source of contaminants to continental shelf ecosystems. This paper reviews recent research on the biological ... -
Environmental impacts of the diver operated C disc to harvest sea urchins and for kelp restoration
(NIVA-rapport;7737-2022, Research report, 2022)NIVA did a 2-day environmental evaluation of the diver operated suction device “C disc” constructed by C robotics. Because the C disc uses suction from a water pump to suck sea urchins from the seafloor, it will collect ... -

(NIVA-rapport;7271, Research report, 2018)This report is a deliverable of the project, IWRM, Institutional Building and Training, a collaborative effort by the Ministry of Natural Resources and Environmental Conservation (MONREC) and the Norwegian Institute for ... -
Environmental Optima for Seven Strains of Pseudochattonella (Dictyochophyceae, Heterokonta)
(Journal article; Peer reviewed, 2013)The ichthyotoxic flagellate Pseudochattonella has formed recurrent blooms in the North Sea, Skagerrak and Kattegat since 1998. Five strains of Pseudochattonella farcimen and two strains of P. verruculosa were examined in ... -
Environmental risk assessment of combined effects in aquatic ecotoxicology: A discussion paper
(Journal article; Peer reviewed, 2014)Environmental regulatory edicts within the EU, such as the regulatory framework for chemicals REACH (Registration, Evaluation, Authorisation and Restriction of Chemicals), the Water Framework Directive (WFD), and the Marine ... -
Environmental risk assessment of veterinary medicinal products intended for use in aquaculture in Europe: the need for developing a harmonised approach
(Peer reviewed; Journal article, 2021)The current and future expansion of aquaculture production appears to be only manageable by using veterinary medicinal products (VMPs) to prevent and reduce disease outbreaks. However, only a very low number of VMPs are ... -
Environmental, social and economic sustainability considerations of aquaponics. The case of an aquaponic system at a Norwegian high school
(NIVA-rapport;7980-2024, Research report, 2024)This report covers how aquaponics contributes to the sustainability transition by discussing some of the main positive and negative environmental, social and economic aspects. It does this by taking a closer look into how ... -
Epifaunal and infaunal responses to submarine mine tailings in a Norwegian fjord
(Journal article; Peer reviewed, 2019)Disposal of mine tailings in marine shallow water ecosystems represents an environmental challenge, and the present paper reports results from a field study in Frænfjorden, Norway, which is subject to such disposal. ... -
Epigenetic, transcriptional and phenotypic responses in Daphnia magna exposed to low-level ionizing radiation
(Peer reviewed; Journal article, 2020)Ionizing radiation is known to induce oxidative stress and DNA damage as well as epigenetic effects in aquatic organisms. Epigenetic changes can be part of the adaptive responses to protect organisms from radiation-induced ... -
