Macronutrient biogeochemistry in Antarctic land-fast sea ice: Insights from a circumpolar data compilation
(Peer reviewed; Journal article, 2023)Antarctic sea ice plays an important role in Southern Ocean biogeochemistry and mediating Earth's climate system. Yet our understanding of biogeochemical cycling in sea ice is limited by the availability of relevant data ... -
Macrophytes as habitat for fish
(Peer reviewed; Journal article, 2022)As different macrophyte habitats house different distributions of invertebrates, we questioned if differences in the composition of fish in these habitats also could be identified. Additionally, we addressed the question ... -
Magnetic Compass Orientation in the European Eel
(Journal article; Peer reviewed, 2013-03-15)European eel migrate from freshwater or coastal habitats throughout Europe to their spawning grounds in the Sargasso Sea. However, their route (~ 6000 km) and orientation mechanisms are unknown. Several attempts have been ... -

Magnetic fields generated by submarine power cables have a negligible effect on the swimming behavior of Atlantic lumpfish (Cyclopterus lumpus) juveniles
(Peer reviewed; Journal article, 2023)Submarine power cables carry electricity over long distances. Their geographic distribution, number, and areal coverage are increasing rapidly with the development of, for example, offshore wind facilities. The flow of ... -
Magnetic fields generated by the DC cables of offshore wind farms have no effect on spatial distribution or swimming behavior of lesser sandeel larvae (Ammodytes marinus)
(Peer reviewed; Journal article, 2022)In the North Sea, the number and size of offshore wind (OW) turbines, together with the associated network of High Voltage Direct Current (HVDC) subsea cables, will increase rapidly over the coming years. HVDC cables produce ... -
Maintaining precision calibrations with optimal copper spheres
(Journal article; Peer reviewed, 1983)Effects of variations in quantities influencing the backscattering cross sections of solid elastic spheres are studied through a particular case. This is that of the 60-mm-diam copper sphere, which is being used worldwide ... -
Maintenance of genetic diversity: challenges for management of marine resources
(ICES CM documents, Working paper, 2002)There are three general classes of threat to biodiversity at the gene level: 1) extinction, which results in complete and irreversible loss of genes; 2) hybridization, which may cause re-arrangement of co-adapted genes and ... -
Major fine-scale spatial heterogeneity in accumulation of gelatinous carbon fluxes on the deep seabed
(Peer reviewed; Journal article, 2023)Abyssal plain communities rely on the overlying water column for a settling flux of organic matter. The origin and rate of this flux as well as the controls on its fine-scale spatial distribution following seafloor settlement ... -
Major histocompatibility complex (MHC) variation and susceptibility to the sea louse Lepeophtheirus salmonis in Atlantic salmon Salmo salar
(Journal article; Peer reviewed, 2007-06-07)The relationship between genetic variation in major histocompatibility complex (MHC) Class I and II genes and susceptibility to sea lice Lepeophtheirus salmonis (Krøyer) in Atlantic salmon Salmo salar (L.) was studied ... -
Makevalg hos homarid hummer; kan de gjenkjenne sin egen art?
(Fisken og havet, Research report, 2003)As European and American lobsters are so similar that it is difficult to spot the difference, and as they have so many similarities in behaviour and life history, this study was initiated to test if they could make ... -
Making the best of lousy circumstances: The impact of salmon louse Lepeophtheirus salmonis on depth preference of sea trout Salmo trutta
(Peer reviewed; Journal article, 2020)Sea trout are known for seeking out sources of freshwater to rid themselves of salmon lice. However, the effect of natural haloclines in fjords on parasite dynamics is not well understood. We tagged 48 naturally infested ... -
Making use of Johan Hjort's “unknown” legacy: reconstruction of a 150-year coastal time-series on northeast Arctic cod (Gadus morhua) liver data reveals long-term trends in energy
(Journal article; Peer reviewed, 2014-03-11)Hidden within the seminal 1914 publication by Johan Hjort, we find what is probably one of the first comprehensive teleost time-series ever published. The series is liver size and fat content of northeast Arctic (NEA) cod ... -

Makrellen ”kokes” til døde på åpent hav
(Havforskningsnytt, Working paper, 2007)Stor makrell betales langt bedre enn mindre makrell. Når båtene i notflåten skal avgjøre kvantum og størrelsen på fisken i et kast, vil mange tørke nota så mye opp at fisken blir trengt og begynner å ”koke” før det tas ... -
