Metrics of the Hadley circulation strength and associated circulation trends
(Journal article; Peer reviewed, 2022)This study compares trends in the Hadley cell (HC) strength using different metrics applied to the ECMWF ERA5 and ERA-Interim reanalyses for the period 1979–2018. The HC strength is commonly evaluated by metrics derived ... -
Metrics to assess the mitigation of global warming by carbon capture and storage in the ocean and in geological reservoirs
(Peer reviewed; Journal article, 2004-09-18)Different metrics to assess mitigation of global warming by carbon capture and storage are discussed. The climatic impact of capturing 30% of the anthropogenic carbon emission and its storage in the ocean or in geological ... -
Mg/Ca ratios in the planktonic foraminifer Neogloboquadrina pachyderma (sinistral) in the northern North Atlantic/Nordic Seas
(Peer reviewed; Journal article, 2006-06-15)In core top samples in the Nordic Seas, Mg/Ca ratios of N. pachyderma (sin.) are generally consistent with previous high-latitude calibration data but do not reflect the modern calcification temperature gradient from 2ºC ... -
Microbial behavior and hydrogen consumption of Oleidesulfovibrio alaskensis - Implications for subsurface hydrogen storage
(Master thesis, 2023-06-01)To reduce global warming an energy transition going from fossil fuel to renewable energy is required and energy storage opportunities to store surplus electricity are needed. Hydrogen gas (H2) is an energy carrier and can ... -
Microstructure Measurements from an Underwater Glider in the Turbulent Faroe Bank Channel Overflow
(Peer reviewed; Journal article, 2014-05)Measurements of ocean microstructure are made in the turbulent Faroe Bank Channel overflow using a turbulence instrument attached to an underwater glider. Dissipation rate of turbulent kinetic energy « is measured using ... -
Microstructure measurements using a glider in the Faroe Bank Channel Overflow
(Master thesis, 2013-05-30)The application of turbulence instrumentation on underwater gliders is addressed, and two methods for glider-inferred dissipation rates of turbulent kinetic energy are evaluated against a ship-based vertical microstructure ... -
Miljøpåvirkninger fra produksjon og bruk av hydrogen i maritim transport
(Master thesis, 2020-07-01)I denne studien er hydrogen foreslått som et alternativt drivstoff for maritim transport. Miljøpåvirkninger fra å erstatte konvensjonelle fossile brensler i sjøtransport med hydrogen vurderes ved å utføre en livssyklusvurdering ... -
Mind the gap – Relevant design for laboratory oil exposure of fish as informed by a numerical impact assessment model
(Journal article; Peer reviewed, 2023)Laboratory experiments provide knowledge of species-specific effects thresholds that are used to parameterize impact assessment models of oil contamination on marine ecosystems. Such experiments typically place individuals ... -
Mitigating climate biases in the midlatitude North Atlantic by increasing model resolution: SST gradients and their relation to blocking and the jet
(Journal article; Peer reviewed, 2022)Starting to resolve the oceanic mesoscale in climate models is a step change in model fidelity. This study examines how certain obstinate biases in the midlatitude North Atlantic respond to increasing resolution (from 1° ... -
Mitigation of offshore wind power intermittency by interconnection of production sites
(Journal article; Peer reviewed, 2020)This study uses a unique set of hourly wind speed data observed over a period of 16 years to quantify the potential of collective offshore wind power production. We address the well-known intermittency problem of wind power ... -
Mixing in the stratified interface of the Faroe Bank Channel overflow: the role of transverse circulation and internal waves
(Peer reviewed; Journal article, 2011-07)The overflow of cold water across the Faroe Bank Channel sill is a significant volume flux of dense water to the North Atlantic Ocean. Using observations of hydrography, current and microstructure from a 1 week cruise and ... -
Mixing of the Storfjorden overflow (Svalbard Archipelago) inferred from denstity overturns
(Journal article, 2004-01-03)Observations were made of the dense overflow from Storfjorden from a survey conducted at closely spaced stations in August 2002. The field data set consists of conventional conductivity-temperature-depth profiles and ... -
Mixing processes in the changing Arctic Ocean
(Doctoral thesis, 2017-08-11)The Arctic has undergone tremendous changes the last decades, including a strong decline in sea ice extent and thickness. The rapid pace of Arctic changes relative to the global changes are known as Arctic amplification, ... -
Mixing rates and vertical heat fluxes north of Svalbard from Arctic winter to spring
