Precipitation over southern Africa: is there consensus among global climate models (GCMs), regional climate models (RCMs) and observational data?
(Peer reviewed; Journal article, 2022)The region of southern Africa (SAF) is highly vulnerable to the impacts of climate change and is projected to experience severe precipitation shortages in the coming decades. Ensuring that our modeling tools are fit for ... -
Predation by Eurasian otters on adult Atlantic salmon
(Master thesis, 2022)The return of the Eurasian otter to western Norway has sparked human-predator conflicts as otters prey on vulnerable Atlantic salmon populations. Although predation may not be the direct cause of salmon population declines, ... -
Predation research with electronic tagging
(Peer reviewed; Journal article, 2022)Predation is a fundamental aspect of ecology that drives ecosystem structure and function. A better understanding of predation can be facilitated by using electronic tags that log or transmit positions of predator or prey ... -
Predicting biomass and hydrocarbon productivities and colony size in continuous cultures of Botryococcus braunii showa
(Peer reviewed; Journal article, 2021)Mathematical models were developed to predict biomass and hydrocarbon productivities and colony size (ouputs) of Botryococcus braunii showa cultures based on light intensity, temperature and dilution rate (inputs). These ... -
Predicting the nationwide outmigration timing of Atlantic salmon (Salmo salar) smolts along 12 degrees of latitude in Norway
(Journal article; Peer reviewed, 2021)Aim Accurate predictions about transition timing of salmon smolts between freshwater and marine environments are key to effective management. We aimed to use available data on Atlantic salmon smolt migration to predict ... -
Predictors and prediction skill for marine cold air outbreaks over the Barents Sea
(Peer reviewed; Journal article, 2021)Marine cold air outbreaks (MCAOs) create conditions for hazardous maritime mesocyclones (polar lows) posing risks to marine infrastructure. For marine management, skilful predictions of MCAOs would be highly beneficial. ... -
Preformed properties for marine organic matter and carbonate mineral cycling quantification
(Peer reviewed; Journal article, 2021)We estimate preformed ocean phosphate, nitrate, oxygen, silicate, and alkalinity by combining a reconstruction of ventilation pathways in the ocean interior with estimates of submixed layer properties. These new preformed ... -
Process-based estimate of global-mean sea-level changes in the Common Era
(Journal article; Peer reviewed, 2022)Although the global-mean sea level (GMSL) rose over the twentieth century with a positive contribution from thermosteric and barystatic (ice sheets and glaciers) sources, the driving processes of GMSL changes during the ... -
Processes Driving Global Interior Ocean pH Distribution
(Peer reviewed; Journal article, 2020)Ocean acidification evolves on the background of a natural ocean pH gradient that is the result of the interplay between ocean mixing, biological production and remineralization, calcium carbonate cycling, and temperature ... -
Projecting circum-Arctic excess-ground-ice melt with a sub-grid representation in the Community Land Model
(Journal article; Peer reviewed, 2020)To address the long-standing underrepresentation of the influences of highly variable ground ice content on the trajectory of permafrost conditions simulated in Earth system models under a warming climate, we implement a ... -
Proteomics and lipidomics analyses reveal modulation of lipid metabolism by perfluoroalkyl substances in liver of Atlantic cod (Gadus morhua)
(Journal article; Peer reviewed, 2020)The aim of the present study was to investigate effects of defined mixtures of polycyclic aromatic hydrocarbons (PAHs) and perfluoroalkyl substances (PFASs), at low, environmentally relevant (1× = L), or high (20× = H) ... -
Prøvefiske etter regnbueaure i Herdlefjorden ett år etter rømmingen ved Angelskår
(LFI – Laboratorium for ferskvannsøkologi og innlandsfiske, Research report, 2016)Under stormen «NINA» 10-11. januar 2015 rømte det omlag 69 000 regnbueaure fra Sjøtroll Havbruk AS sitt anlegg Angelskår i Sørfjorden ved Osterøy. Gjenfangstfiske etter rømmingen resulterte i en gjenfangst av rundt 62 000 ... -
Prøvefiske i Bergsvatnet i Vaksdal kommune 2007
(LFI – Laboratorium for ferskvannsøkologi og innlandsfiske, Research report, 2009)Ved prøvefiske i Bergsvatnet i Vaksdal kommune i august 2007 ble det fanget aure i bunngarn og flytegarn. Aurebestanden i Bergsvatnet var over middels tett. Veksten til auren så ut til å avta når den var eldre enn 5 år og ... -
Prøvefiske i Langavatnet og Håvardsvatnet for AS Tyssefaldene, august 2006
(LFI – Laboratorium for ferskvannsøkologi og innlandsfiske, Research report, 2007)Hensikten med prøvefisket i Langavatnet og Håvardsvatnet i 2006, var å få oppdatert bestandsstatus for aure etter omleggingen av fiskeutsettingene, kontrollere om det var innslag av naturlig rekruttering av aure til ... -
Prøvefiske i magasiner i Tyssedalsfjellene for AS Tyssefaldene, august 2010. Undersøkelse av bestandsstatus for aure
(LFI – Laboratorium for ferskvannsøkologi og innlandsfiske, Research report, 2011)Målsettinger for fiskeundersøkelsene i Tyssedal i 2010 var å oppdatere bestandsstatus for aure, undersøke innslag av naturlig rekruttering, vurdere tiltak for å styrke naturlig rekruttering og tilslag på utsatt fisk, og å ... -
Prøvefiske i Torfinnsvatnet, august 2009
(LFI – Laboratorium for ferskvannsøkologi og innlandsfiske, Research report, 2010)Grunneiere har rapportert at fisken i Torfinnsvatnet var i ferd med å få dårligere kondisjon. Magasinet ble derfor prøvefisket på oppdrag fra BKK i august 2009 for å vurdere aurebestanden og størrelsen på det årlige ... -
The pseudo-global-warming (PGW) approach: Methodology, software package PGW4ERA5 v1.1, validation, and sensitivity analyses
