Measurement of fish target strength with a split-beam echo sounder
(Journal article; Peer reviewed, 1986)Data derived with a 38-kHz split-beam echo sounder have been analyzed to yield target strengths suitable for use with echo integrators. This has required compensation for both thresholding and saturation, since these ... -
Measurements of underwater noise radiated by commercial ships at a cabled ocean observatory
(Journal article; Peer reviewed, 2020)Measurements of underwater noise radiated under ship normal operations are presented. The acoustic data, from the cabled ocean observatory, are analyzed under each identified ship passage, which was obtained by the Automatic ... -
Measuring Adversarial Robustness using a Voronoi-Epsilon Adversary
(Peer reviewed; Journal article, 2023)Previous studies on robustness have argued that there is a tradeoff between accuracy and adversarial accuracy. The tradeoff can be inevitable even when we neglect generalization. We argue that the tradeoff is inherent to ... -
Mechanisms of Ocean Heat Anomalies in the Norwegian Sea
(Journal article; Peer reviewed, 2019)Ocean heat content in the Norwegian Sea exhibits pronounced variability on interannual to decadal time scales. These ocean heat anomalies are known to influence Arctic sea ice extent, marine ecosystems, and continental ... -
Mechanisms regulating oocyte recruitment and skippedspawning in Northeast Arctic cod (Gadus morhua L.)
(Journal article; Peer reviewed, 2009-09)To examine mechanisms that affect fecundity, atresia and skipped spawning in Northeast Arctic cod (Gadus morhua L.), we conducted an experiment where wild-caught cod (>60 cm) kept under restricted food regimes were subjected ... -
Mechanisms underlying recent Arctic atlantification
(Peer reviewed; Journal article, 2020)Recent warming and reduced sea ice concentrations in the Atlantic sector of the Arctic Ocean are the main signatures of ongoing Arctic “Atlantification.” The mechanisms driving the warming trends are nevertheless still ... -
Mercury bioaccumulation pathways in tusk (Brosme brosme) from Sognefjord, Norway: Insights from C and N isotopes
(Peer reviewed; Journal article, 2020)Seafood is the main source of methylmercury (MeHg) exposure for humans and elevated total mercury (Hg) concentrations have been reported in marine fish from Norwegian fjords compared with offshore areas. Hg in tusk fillets ... -
The mercury science-policy interface: History, evolution and progress of the Minamata Convention
(Peer reviewed; Journal article, 2020)Mercury (Hg) pollution is an important environmental and public health issue that has garnered significant interest from policy makers and the global regulatory community. Consumption of seafood is the primary mechanism ... -
Meroplankton Diversity, Seasonality and Life-History Traits Across the Barents Sea Polar Front Revealed by High-Throughput DNA Barcoding
(Peer reviewed; Journal article, 2021)In many species of marine benthic invertebrates, a planktonic larval phase plays a critical role in dispersal. Very little is known about the larval biology of most species, however, in part because species identification ... -
Mesopelagic fish gas bladder elongation, as estimated from wideband acoustic backscattering measurements
(Peer reviewed; Journal article, 2022)Backscattered acoustic energy from a target varies with frequency and carries information about its material properties, size, shape, and orientation. Gas-bearing organisms are strong reflectors of acoustic energy at the ... -
Mesopelagic flesh shear viscosity estimation from in situ broadband backscattering measurements by a viscous–elastic model inversion
(Peer reviewed; Journal article, 2021)In fisheries acoustics, target strength (TS) is a key parameter in converting acoustic measurements to biological information such as biomass. Modelling is a versatile tool to estimate TS of marine organisms. For swimbladdered ... -
Mesopelagic Species and Their Poential Contribution to Food and Feed Security - A Case Study from Norway
(Peer reviewed; Journal article, 2020)The projected increase in global population will demand a major increase in global food production. There is a need for more biomass from the ocean as future food and feed, preferentially from lower trophic levels. In this ... -
Mesoscale Eddies Are Oases for Higher Trophic Marine Life
(Journal article; Peer reviewed, 2012-01-07) -
A meta-analysis on the nutritional value of insects in aquafeeds
(Peer reviewed; Journal article, 2021)A major challenge for development of sustainable aquafeeds is its dependence on fish meal and fish oil. Similarly, it is unwanted to include more plant ingredients which adds more pressure on resources like arable land, ... -
Metabarcoding as a tool to enhance marine surveillance of nonindigenous species in tropical harbors: A case study in Tahiti
(Peer reviewed; Journal article, 2021)Globalization has increased connectivity between countries enhancing the spread of marine nonindigenous species (NIS). The establishment of marine NIS shows substantial negative effects on the structure and functioning of ... -
Metabolic and molecular signatures of improved growth in Atlantic salmon (Salmo salar) fed surplus levels of methionine, folic acid, vitamin B6 and B12 throughout smoltification.
(Peer reviewed; Journal article, 2021)A moderate surplus of the 1C nutrients methionine, folic acid, vitamin B6 and B12 above dietary recommendations for Atlantic salmon has shown to improve growth and reduce hepatosomatic index in the on-growing salt water ... -
Metabolic effects of diet containing blue mussel (Mytilus edulis) and blue mussel-fed salmon in a mouse model of obesity
(Peer reviewed; Journal article, 2023)Alternative feed ingredients for farmed salmon are warranted due to increasing pressure on wild fish stocks. As locally farmed blue mussels may represent an environmentally sustainable substitute with a lower carbon ... -
The metabolic rate response to feed withdrawal in Atlantic salmon post-smolts
(Peer reviewed; Journal article, 2020)Feed withdrawal is a widespread practice in Atlantic salmon (Salmo salar) aquaculture to empty the gut prior to major farming operations, while certain pathogens and suboptimal environmental conditions in production cages ... -
