Acidification of the Nordic Seas
(Peer reviewed; Journal article, 2022)Due to low calcium carbonate saturation states, and winter mixing that brings anthropogenic carbon to the deep ocean, the Nordic Seas and their cold-water corals are vulnerable to ocean acidification. Here, we present a ... -
Acoustic classification in multifrequency echosounder data using deep convolutional neural networks
(Peer reviewed; Journal article, 2020)Acoustic target classification is the process of assigning observed acoustic backscattering intensity to an acoustic category. A deep learning strategy for acoustic target classification using a convolutional network is ... -
Acoustic detection of the Greenland shark (Somniosus microcephalus) using multifrequency split beam echosounder in Svalbard waters
(Peer reviewed; Journal article, 2022)The conservation status of the long-lived Greenland shark (Somniosus microcephalus) is unknown, and methods for non-invasively estimating local or regional abundances are wanted. Using a multifrequency split beam echosounder ... -
Acoustic manual for the krill synoptic survey in 2019
(CCAMLR;WG-EMM-18/12, Research report, 2018)The previously presented document at the 2018 ASAM WG meeting (ASAM-18-07) described a design and plans for a synoptic krill acoustic survey in CCAMLR area 48 in 2019. The survey involves the collaborative efforts of Norway, ... -
Acoustic micronektonic distribution and density is structured by macroscale oceanographic processes across 17–48° N latitudes in the North Atlantic Ocean
(Peer reviewed; Journal article, 2023)This study investigates the large-scale distribution patterns of the acoustic scattering layers and micronekton density across the Northeast Atlantic Ocean during daylight hours. A research cruise on board R/V “Kronprins ... -
Acoustic scattering layers reveal a faunal connection across the Fram Strait
(Peer reviewed; Journal article, 2020)Acoustic scattering layers (SL) at various depths are common phenomena in most oceans, but the organisms that make up these layers vary and so does their density, and hence the backscattered energy. During two crossings ... -
The Acute and Delayed Mortality of the Northern Krill (Meganyctiphanes norvegica) When Exposed to Hydrogen Peroxide
(Peer reviewed; Journal article, 2020)Bath treatment pharmaceuticals used to control sea lice infestations in the salmonid industry, such as hydrogen peroxide (H2O2), are released directly into the environment where non-target organisms are at risk of exposure. ... -
Acute stress response on Atlantic salmon: a time-course study of the effects on plasma metabolites, mucus cortisol levels, and head kidney transcriptome profile
(Peer reviewed; Journal article, 2022)Farmed Atlantic salmon (Salmo salar) welfare and performance can be strongly influenced by stress episodes caused by handling during farming practices. To better understand the changes occurring after an acute stress ... -
Acute toxic effects of hydrogen peroxide, used for salmon lice treatment, on the survival of polychaetes (Capitella sp. and Ophryotrocha spp.)
(Journal article; Peer reviewed, 2018)The amount of hydrogen peroxide (H2O2) used in the treatment of salmon lice in Norwegian salmon farming increased from 308 tons in 2009 to 43246 tons in 2015. For 2016 and 2017, however, the consumption was reduced to 26597 ... -
'Adaptation science' is needed to inform the sustainable management of the world's oceans in the face of climate change
(Peer reviewed; Journal article, 2022)The global response to the challenge of increasingly rapid and severe climate change is shifting from a focus on mitigation and remediation of impacts to a pragmatic adaptation framework. Innovative adaptive solutions that ... -
Adaptation to Low Salinity Promotes Genomic Divergence in Atlantic Cod (Gadus morhua L.)
(Journal article; Peer reviewed, 2015-05-20)How genomic selection enables species to adapt to divergent environments is a fundamental question in ecology and evolution. We investigated the genomic signatures of local adaptation in Atlantic cod (Gadus morhua L.) along ... -
Adaptive and plastic variation in growth and maturation of the cutlassfish Trichiurus japonicus in the subtropical Pacific Ocean
(Peer reviewed; Journal article, 2018) -
Adaptive photoperiod interpretation modulates phenological timing in Atlantic salmon
(Peer reviewed; Journal article, 2023)Photoperiod, the portion of 24-h cycle during which an organism is exposed to illumination, is an important phenological cue in many animals. However, despite its influence on critical biological processes, there remain ... -
Adding fish waste to the diet of Iceland scallop Chlamys islandica: effects on feeding and reproductive ability
(Peer reviewed; Journal article, 2023)Organic enrichment from fish farming may impact benthic species and habitats in adjacent areas. Norwegian salmon farming is continuously growing, but, due to area conflicts and severe sea-lice problems in the western areas, ... -
Additive Models Reveal Sources of Metals and Organic Pollutants in Norwegian Marine Sediments
(Peer reviewed; Journal article, 2017) -
Addressing class imbalance in deep learning for acoustic target classification
(Peer reviewed; Journal article, 2023)Acoustic surveys provide important data for fisheries management. During the surveys, ship-mounted echo sounders send acoustic signals into the water and measure the strength of the reflection, so-called backscatter. ... -
Adipose MDM2 regulates systemic insulin sensitivity
(Peer reviewed; Journal article, 2021)The intimate association between obesity and type II diabetes urges for a deeper understanding of adipocyte function. We and others have previously delineated a role for the tumor suppressor p53 in adipocyte biology. Here, ... -
