Parameterization of drag and dissolution of rising CO2 drops in seawater
(Journal article, 2005-05-24)In this work the dynamics and dissolution of a hydratecovered CO2 drop were studied, using a numeric model and data from one of very few CO2 experiments performed in the real ocean. A theory including the standard drag ... -
Particle aggregation at the edges of anticyclonic eddies and implications for distribution of biomass
(Peer reviewed; Journal article, 2012-06-14)Acoustic measurements show that the biomass of zooplankton and mesopelagic fish is redistributed by mesoscale variability and that the signal extends over several hundred meters depth. The mechanisms governing this ... -
Past climate variability: model analysis and proxy intercomparison
(Doctoral thesis, 2010-10-22)This thesis investigates the climate variability of the late Quaternary (21 000 yrs BP to present day) using model simulations and proxy data. The thesis consists of four manuscripts and one appendix. In the first two ... -
Pathways and export of Greenland Sea Water. In: The Nordic Seas: an integrated perspective
(Geophysical Monograph Series;158, Chapter, 2005) -
Pathways and Water Mass Transformation Along and Across the Mohn‐Knipovich Ridge in the Nordic Seas
(Journal article; Peer reviewed, 2020)Atlantic Water takes various pathways through the Nordic Seas, and its transformation to denser waters forms a crucial connection to the lower limb of the Atlantic Meridional Overturning Circulation. Circulation maps often ... -
Peak-summer energy and carbon fluxes on a thawing permafrost site
(Master thesis, 2018-12-13)We present measurements of surface fluxes taken between 7 July and 6 August 2017, on a palsa mire near the Iškoras mountain in Finnmark, northern Norway. Palsa mires are a particular landform found at the edge of the ... -
Permeability of young sea ice from microtomographic images
(Master thesis, 2011-02)The permeability of sea ice controls the transport of substances through the ice and thereby its surface properties as well as the exchange of heat, salt and gas between ice, ocean and atmosphere. More observations and ... -
Perturbation in the atmospheric acoustic field from a large offshore wind farm in the presence of surface gravity waves
(Peer reviewed; Journal article, 2013)In this study a quantitatively reliable approximation of atmospheric sound wave propagation is given in the presence of a large wind farm. Rough sea surface is used as lower boundary condition at the sea surface, and an ... -
Physical-Biogeochemical Couplings in the Land-Ocean Transition Zone
(Master thesis, 2014-06-03)A significant fraction of global primary production takes place on continental shelves. Due to their interactions with the open oceans, they are highly relevant for the cycling of nutrients, oxygen, and carbon, not only ... -
Polar low le Cygne: Satellite observations and numerical simulations
(Journal article, 2004)A polar low (PL) which occurred in October 1993 over the Norwegian Sea is investigated from an observational and a numerical point of view. This PL has several unique features: it developed early in the season, it lasted ... -

Polar lows – moist-baroclinic cyclones developing in four different vertical wind shear environments
(Journal article; Peer reviewed, 2021)Polar lows are intense mesoscale cyclones that develop in polar marine air masses. Motivated by the large variety of their proposed intensification mechanisms, cloud structure, and ambient sub-synoptic environment, we use ... -
A Possible Feedback Mechanism Involving the Arctic Freshwater, the Arctic Sea Ice, and the North Atlantic Drift
(Advances in Atmospheric Sciences;21( 5), Journal article, 2004-03-15)Model studies point to enhanced warming and to increased freshwater fluxes to high northern latitudes in response to global warming. In order to address possible feedbacks in the ice-ocean system in response to such changes, ... -

Potential and challenges of wind measurements using met-masts in complex topography for bridge design: Part I - Integral flow characteristics
(Journal article; Peer reviewed, 2021-03-10)The paper investigates the local topographic effect on the mean and integral flow characteristics recorded by sonic anemometers mounted on tall masts near the shoreline of three different Norwegian fjords. Two years of ... -
Potential and challenges of wind measurements using met-masts in complex topography for bridge design: Part II – Spectral flow characteristics
(Journal article; Peer reviewed, 2021)This study quantifies the influence of the local topography on sonic anemometer measurements mounted on tall met-masts deployed in Norwegian fjords. This assessment is done by analysing the second-order structure of ... -
Potential and limitations in estimating sensible-heat-flux profiles from consecutive temperature profiles using remotely-piloted aircraft systems
(Peer reviewed; Journal article, 2020)Profiles of the sensible heat flux are key to understanding atmospheric-boundary-layer (ABL) structure and development. Based on temperature profiling by a remotely-piloted aircraft system (RPAS), the Small Unmanned ... -
Potential changes in the connectivity of marine protected areas driven by extreme ocean warming
(Journal article; Peer reviewed, 2021)Projected future climate scenarios anticipate a warmer tropical ocean and changes in surface currents that will likely influence the survival of marine organisms and the connectivity of marine protected areas (MPAs) networks. ... -
Pre-bloom dynamics of the Subpolar North Atlantic microbial food web
(Master thesis, 2013-02-18)The aim of this study was to investigate the microbial planktonic food web in the pre- bloom period of the Subpolar North Atlantic Ocean. Through repeated visits to the Icelandic Basin, Norwegian Basin, and on the Shetland ...
