A mechanical energy budget for the North Sea
(Pergamon, 2004-06-29)A three-dimensional baroclinic numerical model is used to quantify the components of the mechanical energy budget for a semi-enclosed sea, the North Sea. As anticipated, tidal energy is the largest supplier of mechanical ...Journal article -
Mechanisms affecting the transport of early stages of Norwegian Coastal Cod - a fjord study
(The University of Bergen, 2008-05-30)The fjord system of Sørfolda and Nordfolda situated in northern Norway is used in a model study. Particularly to explore the mechanisms causing separation and mixing of eggs from Arcto-Norwegian Cod (ANC) and Norwegian Coastal ...Master thesis -
Mechanisms for decadal scale variability in a simulated Atlantic Meridional Overturning Circulation
(Springer Verlag, 2011-06-25)Variability in the Atlantic Meridional Overturning Circulation (AMOC) has been analysed using a 600-year pre-industrial control simulation with the Bergen Climate Model. The typical AMOC variability has amplitudes of 1 ...Peer reviewedJournal article -
Mesoscale Eddies Are Oases for Higher Trophic Marine Life
(Public Library of Science, 2012-01-17)Mesoscale eddies stimulate biological production in the ocean, but knowledge of energy transfers to higher trophic levels within eddies remains fragmented and not quantified. Increasing the knowledge base is constrained ...Peer reviewedJournal article -
Mesoscale variability study of the Agulhas Current from satellite radar altimetry and a high resolution model
(The University of Bergen, 2006-06)Towards understanding the dynamics and eddy evolving processes in the greater Agulhas Current system, a Hybrid Coordinate Ocean Model (HYCOM) system has been set up to simulation the ocean circulation around Southern ...Master thesis -
Metrics to assess the mitigation of global warming by carbon capture and storage in the ocean and in geological reservoirs
(American Geophysical Union, 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 ...Journal articlePeer reviewed -
Mg/Ca ratios in the planktonic foraminifer Neogloboquadrina pachyderma (sinistral) in the northern North Atlantic/Nordic Seas
(American Geophysical Union, 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 ...Journal articlePeer reviewed -
Microstructure Measurements from an Underwater Glider in the Turbulent Faroe Bank Channel Overflow
(American Meteorological Society, 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 ...Journal article -
Microstructure measurements using a glider in the Faroe Bank Channel Overflow
(The University of Bergen, 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 ...Master thesis -
Mixing in the stratified interface of the Faroe Bank Channel overflow: the role of transverse circulation and internal waves
(Wiley, 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 ...Journal article -
Mixing of the Storfjorden overflow (Svalbard Archipelago) inferred from denstity overturns
(American Geophysical Union, 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 ...Journal article -
Mixing processes in the changing Arctic Ocean
(The University of Bergen, 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, ...Doctoral thesis -
Mixing rates and vertical heat fluxes north of Svalbard from Arctic winter to spring
(Wiley, 2017-06)Mixing and heat flux rates collected in the Eurasian Basin north of Svalbard during the N-ICE2015 drift expedition are presented. The observations cover the deep Nansen Basin, the Svalbard continental slope, and the shallow ...Journal article -
A model study of the seasonal and long-term North Atlantic surface pCO(2) variability
(Copernicus Publications, 2012-03-05)A coupled biogeochemical-physical ocean model is used to study the seasonal and long–term variations of surface pCO2 in the North Atlantic Ocean. The model agrees well with recent underway pCO2 observations from the Surface ...Journal article -
Modeling coastal circulation in Norway using a high-resolution 4D-Var ocean assimilation system
(The University of Bergen, 2017-06-23)The circulation along the Norwegian coast is characterized by many transient smallscale features such as eddies and meanders that are challenging to reproduce by means of numerical modeling. In this thesis I investigate ...Doctoral thesis -
Modeling ocean processes below Fimbulisen, Antarctica
(American Geophysical Union, 2006-01-18)Model simulations of circulation and melting beneath Fimbulisen, Antarctica, obtained using an isopycnic coordinate ocean model, are presented. Model results compare well with available observations of currents and hydrography ...Journal articlePeer reviewed -
