(LFI – Laboratorium for ferskvannsøkologi og innlandsfiske, Research report, 2018)Rapporten består av tre deler: resultater fra gassmetningsovervåking i 2016 og 2017, en analyse av utgassing i Otra nedenfor Brokke, samt en modellering av tiltak til økt lufting av gassovermettet vann. -
Gassmetning i Otra nedenfor Brokke 2018 - 2019
(LFI - Laboratorium for ferskvannsøkologi og innlandsfiske, Research report, 2019)Gassovermetning fra Brokke kraftverk har ligget over 110 % i 35-36 % av tiden i perioden 2018-2019. Toppverdien var 176 % (2018). Årsgangene og intensitet samsvarte med årene før og var preget av 8 uker lange overmetningsperioder ... -
Gassmetning i Otra nedenfor Brokke kraftverk
(LFI - Laboratorium for ferskvannsøkologi og innlandsfiske, Research report, 2016)Overvåking av gassovermetning i Otra nedenfor Brokke kraftverk (2011-2015) har vist at det fantes gassovermetningsbølger opptil 172 % TGP (total gass pressure). I mer enn 45 % av tiden 2013–2015 var gassovermetningen over ... -

Historiske målinger av gassmetning i kraftverksutløpet viste maksnivåer mellom 106 og 184 % TDG i en periode mellom ... -
Gassovermetning i vassdrag – en kunnskapsoppsummering
(LFI - Laboratorium for ferskvannsøkologi og innlandsfiske, Research report, 2018)Denne publikasjonen sammenfatter internasjonal kunnskap om gassovermetning og dens miljøeffekter i vassdrag. Dessuten presenterer vi resultater fra egen overvåking av gassmetning i ti norske elver og tåleforsøk med Atlantisk ... -
Gassovermetning nedstrøms småkraftverk med installert omløpsventil
(LFI - Laboratorium for ferskvannsøkologi og innlandsfiske, Research report, 2015)2014 til 2015 ble gassmetning overvåket nedenfor tre småkraftverk på Vestlandet. Det ble funnet gassovermetning ved alle de tre undersøkte småkraftverkene. Verdiene var lave til moderate. Normalt lå gassmetningen mellom ... -
Generation of the Internal Pycnocline in the Subpolar Southern Ocean by Wintertime Sea Ice Melting
(Peer reviewed; Journal article, 2023)The ocean's internal pycnocline is a layer of elevated stratification that separates the well-ventilated upper ocean from the more slowly renewed deep ocean. Despite its pivotal role in organizing ocean circulation, the ... -
Genetic characterization of AmpC and extended-spectrum beta-lactamase (ESBL) phenotypes in Escherichia coli and Salmonella from Alberta poultry
(Journal article; Peer reviewed, 2021)Horizontal gene transfer is an important mechanism which facilitates bacterial populations in overcoming antimicrobial treatment. In this study, a total of 120 Escherichia coli and 62 Salmonella enterica subsp. enterica ... -
Genetic diversity, gene flow and hybridization in fan-shaped sponges (Phakellia spp.) in the North-East Atlantic deep sea
(Peer reviewed; Journal article, 2022)Deep-sea North Atlantic sponge grounds are crucial components of the marine fauna providing a key role in ecosystem functioning. To properly develop effective conservation and management plans, it is crucial to understand ... -
Glacial-interglacial Circumpolar Deep Water temperatures during the last 800 000 years: estimates from a synthesis of bottom water temperature reconstructions
(Peer reviewed; Journal article, 2024)Future climate and sea level projections depend sensitively on the response of the Antarctic Ice Sheet to ocean-driven melting and the resulting freshwater fluxes into the Southern Ocean. Circumpolar Deep Water (CDW) ... -
Global carbon budget 2019
(Peer reviewed; Journal article, 2019)Accurate assessment of anthropogenic carbon dioxide (CO2) emissions and their redistribution among the atmosphere, ocean, and terrestrial biosphere – the “global carbon budget” – is important to better understand the global ... -
