Minutes of the Advisory Committee on the Marine Environment [Oslo, Norway ASC, September, 2001]
(ICES CM Documents;2001/A:7, Working paper, 2001) -
Missing the marine forest for the trees
(Journal article; Peer reviewed, 2019)Seascapes dominated by large, structurally complex seaweeds are ubiquitous. These critical ecosystems are under increasing pressure from human activities, and conceiving successful management strategies to ensure their ... -
Mitigating the effects of escaped farmed Atlantic salmon: Combining single nucleotide polymorphisms, lipid acid profiling, and statistical methods to trace escaped salmon back to origin
(Rapport fra Havforskningen;Nr. 18-2013, Working paper, 2013-06)Comparisons between 300 polymorphic SNPs and 14 short tandem repeats (STRs) were conducted on a data set consisting of approximately 500 Atlantic salmon arranged in 10 samples/populations. Global FST ranged from 0.033-0.115 ... -
Mixed origin of juvenile Atlantic cod (Gadus morhua) along the Swedish west coast
(Peer reviewed; Journal article, 2022)Cryptic population structure in exploited fishes poses a major challenge for fisheries management. In Atlantic cod, sympatric ecotypes are well-known, for instance off the coast of northern Norway. Recently, two sympatric ... -
Mixed-stock analysis of Atlantic herring (Clupea harengus): a tool for identifying management units and complex migration dynamics
(Peer reviewed; Journal article, 2023) -
Mixture toxicity of chlorpyrifos-methyl, pirimiphos-methyl, and nonylphenol in Atlantic salmon (Salmo salar) hepatocytes
(Peer reviewed; Journal article, 2020)Pesticide formulations typically contain adjuvants added to enhance the performance of the active ingredient. Adjuvants may modify the bioavailability and toxicity of pesticides. In this study, the aim was to examine to ... -
MMP-13 (Matrix MetalloProteinase 13) expression might be an indicator for increased ECM remodeling and early signs of vertebral compression in farmed Atlantic salmon (Salmo salar L.)
(Journal article; Peer reviewed, 2010-04)Vertebral body compression is a common problem in commercial farming of Atlantic salmon. Although risk factors, such as vaccination and alnutrition, have been identified, the etiology is largely unknown. Histological studies ... -
Mock samples resolve biases in diversity estimates and quantitative interpretation of zooplankton metabarcoding data
(Peer reviewed; Journal article, 2023)Metabarcoding is a rapidly developing tool in marine zooplankton ecology, although most zooplankton surveys continue to rely on visual identification for monitoring purposes. We attempted to resolve some of the biases ... -
A model for incorporating changes in distribution of fishing effort in assessment of the effects of changes in trawl mesh size
(Fiskeridirektoratets skrifter, Serie Havundersøkelser, Research report, 1983)Factors invalidating traditional mesh assessments are discussed with special emphasis on changes in distribution of fishing effort between areas inhabited by small and large fish. A model for studying the effects of such ... -
A model for the fate of carbon dioxide from a simulated carbon storage seep
(Peer reviewed; Journal article, 2021)Offshore geological carbon storage (GCS) is a rapidly developing technology essential for meeting international climate goals. While the likelihood of leakage from a properly planned geological sequestration site is low, ... -
A model of Black Sea circulation with strait exchange (2008–2018)
(Peer reviewed; Journal article, 2020)The Bosphorus exchange is of critical importance for hydrodynamics and hydroclimatology of the Black Sea. In this study, we report on the development of a medium-resolution circulation model of the Black Sea, making use ... -
A model of estimating biological attachment of fish stocks to exclusive economic zones
(ICES CM Documents;1993/D:43, Working paper, 1993)The paper describes a model of calculating indices of attachment of fish stock to fisheries zones based on biological parameters. Input data are weight by age, mortality rate and the percentage area distribution of an ... -
A model of vertical distribution of pelagic eggs. A computer realization [HELP 17]
(help, Research report, 1988)The presented mathematical model and it's realization in an interactive computer program describes the vertical distribution of pelagic fish and plankton eggs. The water column has a density gradient and the vertical ... -
Model-informed classification of broadband acoustic backscatter from zooplankton in an in situ mesocosm
(Peer reviewed; Journal article, 2023)Classification of zooplankton to species with broadband echosounder data could increase the taxonomic resolution of acoustic surveys and reduce the dependence on net and trawl samples for ‘ground truthing’. Supervised ... -
Modeling emergent life histories of copepods
(Journal article; Peer reviewed, 2018)The distribution and population dynamics of zooplankton are affected by the interplay between currents, behavior, and selective growth, mortality, and reproduction. Here, we present an individual based model for a copepod ... -
Modeling fish reaction to vessel noise, the significance of the reaction thresholds
(ICES CM documents, Working paper, 2001)A simple model of fish reaction to vessel noise is made. The fish are assumed to swim directly away from the noise source. The main noise source is assumed to be the propeller. Parameters for endurance and swimming speed ... -
Modeling fitness changes in wild Atlantic salmon populations faced by spawning intrusion of domesticated escapees
(Journal article; Peer reviewed, 2018)Genetic interaction between domesticated escapees and wild conspecifics represents a persistent challenge to an environmentally sustainable Atlantic salmon aquaculture industry. We used a recently developed eco‐genetic ... -
Modeling key processes affecting Al speciation and transport in estuaries
(Journal article; Peer reviewed, 2019)Assessments of the impacts of aluminium (Al) to aquatic organisms in estuarine waters have suffered from the lack of available models that can accurately predict the presence of toxic physico-chemical forms (species) of ...
