Abyssal fauna of polymetallic nodule exploration areas, eastern Clarion-Clipperton Zone, central Pacific Ocean: Annelida: Spionidae and Poecilochaetidae
(Journal article; Peer reviewed, 2022)This paper represents a continuation of taxonomic publications on the benthic fauna of polymetallic nodule fields in the eastern ClarionClipperton Zone (CCZ) using material collected during baseline environmental survey ... -
Assessment of the risk of negative impact on biodiversity from import and release of eggs or live fish from landlocked Atlantic salmon from Klarälven in Sweden to Trysilelva in Norway. Scientific Opinion of the Panel on Alien Organisms and Trade in Endangered Species of the Norwegian Scientific Committee for Food and Environment
(VKM Report, Research report, 2021) -
Assimilation of multiple linearly dependent data vectors
(Peer reviewed; Journal article, 2019)Assimilation of a sequence of linearly dependent data vectors, {dl}Ll=1 such that dl=BldLL−1l=1 , is considered for a parameter estimation problem. Such a data sequence can occur, for example, in the context of multilevel ... -
Decomposing oceanic temperature and salinity change using ocean carbon change
(Peer reviewed; Journal article, 2022)As the planet warms due to the accumulation of anthropogenic CO2 in the atmosphere, the interaction of surface ocean carbonate chemistry and the radiative forcing of atmospheric CO2 leads to the global ocean sequestering ... -
Exploring time series of hyperspectral images for cold water coral stress response analysis
(Peer reviewed; Journal article, 2022)Hyperspectral imaging (HSI) is a promising technology for environmental monitoring with a lot of undeveloped potential due to the high dimensionality and complexity of the data. If temporal effects are studied, such as in ... -
Hydropower: gas supersaturation and the role of aquatic plant photosynthesis for fish health
(NIVA-rapport, Research report, 2021)Fish and invertebrates breathing in water supersaturated with gas (total dissolved gas; TDG), e.g. at the outlet of hydropower plants, may develop gas bubble disease (analogous to the bends in humans). Aquatic plants also ... -
Limited role of climate change in extreme low rainfall associated with southern Madagascar food insecurity, 2019-21
(Peer reviewed; Journal article, 2022)Southern Madagascar recently experienced a severe food security crisis, made significantly worse by well below average rainfall from July 2019 to June 2021. This exceptional drought has affected a region with high pre-existing ... -
Neutralisation of hydrogen peroxide after delousing events; technology development and environmental risk assessment
(NIVA-rapport, Research report, 2021)The present project has conducted experiments in laboratory and pilot scale with chemical neutralisation of hydrogen peroxide, which, in combination with technological treatment pose a possible solution for onboard well ... -
Observation-based Sea surface temperature trends in Atlantic large marine ecosystems
(Peer reviewed; Journal article, 2022)Variations in Sea Surface Temperature (SST) are an important driver of marine species abundance in Large Marine Ecosystems (LMEs). Studies concerned with climate change induced SST trends within these LMEs have so far been ... -
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 ... -
A ShK-like Domain from Steinernema carpocapsae with Bioinsecticidal Potential
(Peer reviewed; Journal article, 2022)Entomopathogenic nematodes are used as biological control agents against a broad range of insect pests. We ascribed the pathogenicity of these organisms to the excretory/secretory products (ESP) released by the infective ... -
A Stochastic Covariance Shrinkage Approach in Ensemble Transform Kalman Filtering
(Peer reviewed; Journal article, 2023)The Ensemble Kalman Filters (EnKF) employ a Monte-Carlo approach to represent covariance information, and are affected by sampling errors in operational settings where the number of model realizations is much smaller than ... -
Taxon-rich transcriptomics supports higher-level phylogeny and major evolutionary trends in Foraminifera
(Peer reviewed; Journal article, 2022)Foraminifera, classified in the supergroup Rhizaria, are a common and highly diverse group of mainly marine protists. Despite their evolutionary and ecological importance, only limited genomic data (one partial genome and ...
