Using an omnidirectional video logger to observe the underwater life of marine animals: Humpback whale resting behaviour
(Peer reviewed; Journal article, 2021)Animal-borne video loggers are powerful tools for investigating animal behaviour because they directly record immediate and extended peripheral animal activities; however, typical video loggers capture only a limited area ... -
Using artificial neural networks to combine acoustic and trawl data in the Barents and North Seas
(ICES CM documents, Working paper, 2004)Groundfish have a wide and variable distribution making the use of trawling alone a highly inadequate sampling method. Trawl data provide species identification and numbers over a very small area and habitat type while ... -

Using correlative and mechanistic niche models to assess the sensitivity of the Antarctic echinoid Sterechinus neumayeri to climate change
(Peer reviewed; Journal article, 2021)The Southern Ocean is undergoing rapid environmental changes that are likely to have a profound impact on marine life, as organisms are adapted to sub-zero temperatures and display specific adaptations to polar conditions. ... -
Using feedforward neural networks to represent ecosystem dynamics for bioeconomic analysis
(Peer reviewed; Journal article, 2023)We applied feedforward neural networks to represent ecosystem dynamics that are vital to bioeconomic analysis, ecosystem-based management, or what-if analysis regarding the underlying natural resources. Neural networks are ... -
Using mark-recapture methods to estimate pup production of harp seals (Phoca groenlandica) in the Greenland Sea
(ICES CM documents, Working paper, 1992)During the period 1968-1991 16,917 harp seal pups have been tagged in the Greenland Sea. From 1976 until 1991, there have been 468 recoveries. 73 of these, mostly drowned in fishing gear or part of Inuit catches at Greenland, ... -
Using mixed models to combine smooth size-selection and catch-comparison curves over hauls
(Journal article; Peer reviewed, 2003)Parametric size-selection curves are often combined over hauls to estimate a mean selection curve using a mixed model in which between-haul variation in selection is treated as a random effect. This paper shows how ... -
Using multivariate autoregressive state-space models to examine stock structure of Greenland halibut in the North Atlantic
(Peer reviewed; Journal article, 2023)Accurate information on population structure is essential for effective fisheries management. Greenland halibut (Reinhardtius hippoglossoides) in the North Atlantic is managed as four separate offshore stocks. We use ... -
Using natural analogues to investigate the effects of climate change and ocean acidification on Northern ecosystems
(Peer reviewed; Journal article, 2018)Northern oceans are in a state of rapid transition. Still, our knowledge of the likely effects of climate change and ocean acidification on key species in the food web, functionally important habitats and the structure of ... -

Using Spatial Validity and Uncertainty Metrics to Determine the Relative Suitability of Alternative Suites of Oceanographic Data for Seabed Biotope Prediction. A Case Study from the Barents Sea, Norway
(Peer reviewed; Journal article, 2021)The use of habitat distribution models (HDMs) has become common in benthic habitat mapping for combining limited seabed observations with full-coverage environmental data to produce classified maps showing predicted habitat ... -
Using the best of two worlds: A bio-economic stock assessment (BESA) method using catch and price data
(Others, 2023)Reliable stock assessments are essential for successful and sustainable fisheries management. Advanced stock assessment methods are expensive, as they require age- or length-structured catch and detailed fishery-independent ... -
Using vessel acoustics to detect diving patterns of krill foraging predators automatically: development of a novel method for quantifying impact of krill fishing on seals and penguins
(;WG-EMM-15/25, Research report, 2015-06-20)The aim of this work was to assess the possibilities of automatically generating a dataset of dive behaviour of air-breathing predators, based on acoustic data from a monitoring survey and from commercial krill fishing ... -
Utarbeidelse av et program for overvåkning av eutrofitilstand og- utvikling i norske kystfarvann basert på både tradisjonelle og høyteknologiske metoder
(Fisken og havet, Research report, 1998)This report describes methods for enhancement of the curent strategy for cutrophication surveillance through a case study of the Skagerrak region. As a basis for evaluation of different methods for monitoring ... -
