Pacific circulation response to eastern Arctic sea ice reduction in seasonal forecast simulations
(Journal article; Peer reviewed, 2021)Recent studies point to the sensitivity of mid-latitude winter climate to Arctic sea ice variability. However, there remain contradictory results in terms of character and timing of Northern Hemisphere large-scale circulation ... -
Pacific contribution to decadal surface temperature trends in the Arctic during the twentieth century
(Journal article; Peer reviewed, 2021)Instrumental records suggest multidecadal variability in Arctic surface temperature throughout the twentieth century. This variability is caused by a combination of external forcing and internal variability, but their ... -
Pacific contribution to the early twentieth-century warming in the Arctic
(Journal article; Peer reviewed, 2018)Arctic surface temperature warmed more than twice as fast as global temperature during the early twentieth century, similar to that during the recent global warming. This Arctic warming has been attributed to both external ... -
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 processes of summer extreme rainfall interannual variability in eastern China: Part I—observational analysis
(Journal article; Peer reviewed, 2022)Extreme precipitation can have catastrophic effects in China by triggering floods, landslides, and other natural disasters. We measure extreme precipitation over eastern China by the maximum of five-day precipitation amount ... -
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 ... -
Polycyclic aromatic hydrocarbons (PAHs) and their nitrated and oxygenated derivatives in the Arctic boundary layer: Seasonal trends and local anthropogenic influence
(Journal article; Peer reviewed, 2021)A total of 22 polycyclic aromatic hydrocarbons (PAHs), 29 oxy-PAHs, and 35 nitro-PAHs (polycyclic aromatic compounds, PACs) were measured in gaseous and particulate phases in the ambient air of Longyearbyen, the most ... -
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, ... -
