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) ... -
The pseudo-global-warming (PGW) approach: Methodology, software package PGW4ERA5 v1.1, validation, and sensitivity analyses
(Journal article; Peer reviewed, 2023)The term “pseudo-global warming” (PGW) refers to a simulation strategy in regional climate modeling. The strategy consists of directly imposing large-scale changes in the climate system on a control regional climate ... -
Quantification of eDNA to map the distribution of cold-water coral reefs
(Peer reviewed; Journal article, 2020)Marine litter harms marine life, human wellbeing and the provision of clean seafood. In the Barents Sea, a high portion of this source of pollution derives from fisheries. However, there remains a knowledge gap between ... -
Quantifying stratospheric biases and identifying their potential sources in subseasonal forecast systems
(Peer reviewed; Journal article, 2022)The stratosphere can be a source of predictability for surface weather on timescales of several weeks to months. However, the potential predictive skill gained from stratospheric variability can be limited by biases in the ... -
Quantifying the Intra-Habitat Variation of Seagrass Beds with Unoccupied Aerial Vehicles (UAVs)
(Peer reviewed; Journal article, 2022)Accurate knowledge of the spatial extent of seagrass habitats is essential for monitoring and management purposes given their ecological and economic significance. Extent data are typically presented in binary (presence/absence) ... -
Quantitative molecular detection of larval Atlantic herring (Clupea harengus) in stomach contents of Atlantic mackerel (Scomber scombrus) marks regions of predation pressure
(Journal article; Peer reviewed, 2021)Mortality rates in the early life-history stages of fishes are generally high yet identifying the causes remain unclear. Faltering recruitment rates of Atlantic herring (Clupea harengus) in the Norwegian Sea indicate a ... -
The quest for successful Atlantic salmon restoration: perspectives, priorities, and maxims
(Peer reviewed; Journal article, 2021)Atlantic salmon is often a focal species of restoration efforts throughout the north Atlantic and it is therefore an excellent case study for how best to design programmes to address and mitigate threats and correct ... -
Rapid development and persistence of efficient subglacial drainage under 900 m-thick ice in Greenland
(Journal article; Peer reviewed, 2021)Intensive study of the Greenland Ice Sheet's (GrIS) subglacial drainage has been motivated by its importance for ice dynamics and for nutrient/sediment export to coastal ecosystems. This has revealed consistent seasonal ... -
Rapid landscape changes in plastic bays along the Norwegian coastline
(Peer reviewed; Journal article, 2021)The Norwegian Coastal Current transports natural debris and plastic waste along the Norwegian coastline. Deposition occurs in so-called wreck-bays and includes floating debris, such as seaweed, driftwood and volcanic pumice, ... -
Recent Water Mass Changes Reveal Mechanisms of Ocean Warming
(Peer reviewed; Journal article, 2021)Over 90% of the buildup of additional heat in the Earth system over recent decades is contained in the ocean. Since 2006, new observational programs have revealed heterogeneous patterns of ocean heat content change. It is ... -
Reconciling and Improving Formulations for Thermodynamics and Conservation Principles in Earth System Models (ESMs)
(Peer reviewed; Journal article, 2022)Earth System Models (ESMs) have numerous total energy budget errors. This article establishes the governing total energy equations for large-scale ESMs and assesses the energy budget errors in real-world simulations in a ... -
Reconciling Observation and Model Trends in North Atlantic Surface CO2
(Peer reviewed; Journal article, 2019)The North Atlantic Ocean is a region of intense uptake of atmospheric CO2. To assess how this CO2 sink has evolved over recent decades, various approaches have been used to estimate basin‐wide uptake from the irregularly ...
