Estimerte bidrag fra atmosfæriske avsetninger til nitrogeninnhold i elver
(NIVA-rapport;7678, Research report, 2021)Hovedmålet med prosjektet har vært å estimere hvor stor andel av nitrogenet i vassdragene som kommer fra langtransporterte forurensninger. Arbeidet må betraktes som et forprosjekt basert på utprøving av en forenklet metodikk ... -
Et litteraturstudium over forurenset snø fra bynære områder: stoffer, kilder, effekter og håndtering
(NIVA-rapport;6968, Research report, 2016)Et litteraturstudium ble gjennomført for å utarbeide en oversikt over konsentrasjoner av organiske miljøgifter og metaller i urban snø. I tillegg ble noe litteratur i forhold til veisalting inkludert. Det ble også søkt ... -
Etablering av et demonstrasjonsanlegg for integrert produksjon av fisk og planter på Akvariet i Bergen
(NIVA-rapport;7227, Research report, 2018)Det ble etablert et aquaponics-anlegg på Akvariet i Bergen og samtidig ble konseptet; integrert multitrofisk akvakultur (IMTA) presentert. Systemet ble designet for å ivareta de biologiske kravene så godt det lot seg gjøre, ... -
Ethics of assisted evolution in marine conservation
(Journal article; Peer reviewed, 2019)Climate change is outpacing existing rates of evolution and adaptation for many marine organisms. Human societies are pushing hard to find new solutions to save and protect marine ecosystems, generating research on ... -
Etterundersøkelser av makrovegetasjon og vannkjemi i Børselva 2016
(NIVA-rapport;7148, Research report, 2017)Børselva er regulert og det er foretatt en rekke restaureringstiltak i vassdraget. Formålet med den foreliggende undersøkelsen har vært å undersøke makrovegetasjonen i Børselva og vurdere endringer etter restaureringen. ... -
EuroGOOS roadmap for operational coastal downstream services
(Peer reviewed; Journal article, 2023)The EuroGOOS Coastal working group examines the entire coastal value chain from coastal observations to services for coastal users. The main objective of the working group is to review the status quo, identify gaps and ... -
European Approaches Support an Essential Definition of Ecosystem-Based Management and Demonstrate Its Implementation for the Oceans
(Peer reviewed; Journal article, 2024)Unclear, contested definitions and high complexity have been used to explain why ecosystem-based management (EBM) has been hard to implement. This still seems to be a problem, judging from the unspecific references to it ... -
European policies and legislation targeting ocean acidification in european waters - Current state
(Peer reviewed; Journal article, 2020)Ocean acidification (OA) is a global problem with profoundly negative environmental, social and economic consequences. From a governance perspective, there is a need to ensure a coordinated effort to directly address it. ... -
