Day / night variation in fish directivity in the trawl opening
(ICES CM Documents;1994/B:18, Working paper, 1994)Still photographs of fish in the mouth area of a bottom trawl were taken by a downwards-oriented automated strobe camera mounted near the headrope. Fish angles relative to the towing direction were measured. Fish were ... -
Day and night fish distribution pattern in the net mouth area of the Norwegian bottom-sampling trawl
(Journal article; Peer reviewed, 1990)A high-frequency scanning sonar, mounted as a net sonde, was used to study fish behaviour in the mouth area of the Norwegian bottom-sampling trawl. Fish distribution patterns were significantly different by day and night. ... -
DDT i blåskjel frå fruktområde i vestnorske fjordar 2021 — Prøvar frå Hardangerfjorden og Sognefjorden med vekt på Sørfjorden
(Rapport fra havforskningen;2022 - 29, Research report, 2022)Sidan Sørfjorden i Hardanger er eitt av dei mest konsentrerte fruktdyrkingsområda i Norge, vart det tidlegare brukt mykje DDT til bekjemping av skadedyr. Fjorden har derfor historisk hatt særleg mykje DDT-forureining, og ... -

Decadal trends in ocean acidification from the Ocean Weather Station M in the Norwegian Sea
(Peer reviewed; Journal article, 2022)The Ocean Weather Station M (OWSM) is situated at a fixed position in the Norwegian Sea, one of the major basins of the Nordic Seas, which represents an important area for uptake of atmospheric CO2 as well as deep water ... -

Decline and Recovery of Atlantic Cod (Gadus morhua) Stocks throughout the North Atlantic
(Chapter, 2008)Many stocks of Atlantic cod (Gadus morhua) on both sides of the North Atlantic are currently at much reduced levels of biomass, but this situation is not in all instances the result of long, continuous decline. Most Northwest ... -

Declining size-at-harvest in Norwegian salmon aquaculture: Lice, disease, and the role of stunboats
(Peer reviewed; Journal article, 2022)Sea cages used for fish farming are typically open to the environment, making the grow-out phase a race against the accumulation of infections. In Norway, farmed Atlantic salmon (Salmo salar) suffer outbreaks of salmon ... -
A deep learning-based method to identify and count pelagic and mesopelagic fishes from trawl camera images
(Peer reviewed; Journal article, 2021)Fish counts and species information can be obtained from images taken within trawls, which enables trawl surveys to operate without extracting fish from their habitat, yields distribution data at fine scale for better ... -
A deep scattering layer under the North Pole pack ice
(Peer reviewed; Journal article, 2021)The 3.3 million km2 marine ecosystem around the North Pole, defined as the Central Arctic Ocean (CAO), is a blind spot on the map of the world’s fish stocks. The CAO essentially comprises the permanently ice-covered deep ... -
Deep Semi-Supervised Semantic Segmentation in Multi-Frequency Echosounder Data
(Peer reviewed; Journal article, 2023)Multi-frequency echosounder data can provide a broad understanding of the underwater environment in a non-invasive manner. The analysis of echosounder data is, hence, a topic of great importance for the marine ecosystem. ... -

Deep towed vehicle for fish abundance estimation concept and testing
(ICES CM Documents;1991/B:53, Working paper, 1991)A research program was initiated in Norway in 1988 for measuring the abundance of fish resources at depth from 500 to 1000 metres. It was decided to develope a deep towed vehicle, to bring acoustic transducers down to ... -
