On effect of wave breaking on short wind waves
(Peer reviewed; Journal article, 2004-10)The paper presents an attempt to estimate short wave generation by wave breaking. A breaking wave crest disturbs the surface and generates sub-surface turbulence. The locally disturbed area further disperses and feeds short ... -

Pathways and export of Greenland Sea Water. In: The Nordic Seas: an integrated perspective
(Geophysical Monograph Series;158, Chapter, 2005) -
A quantitative description of the West Spitsbergen Current by combining hydrography, altimetry and in-situ current meters
(Master thesis, 2014-06-02)In a warming Arctic Ocean (AO) it is important to study its main source of oceanic heat and salt. Here, seasonal climatological sections of the West Spitsbergen Current (WSC) across 78.83°N have been constructed using ... -
Relation between the wind stress curl in the North Atlantic and the Atlantic inflow to the Nordic Seas
(Journal of Geophysical Research: Oceans, Journal article, 2008-06-27)In this study an isopycnic coordinate ocean model has been used to investigate the relationships between the North Atlantic wind stress curl (WSC) and the inflow of Atlantic water to the Nordic Seas. For the period 1995–2001, ... -
Sensitivity of remote sensing – derived phytoplankton productivity to mixed layer depth: Lessons from the carbon-based productivity model
(Peer reviewed; Journal article, 2009-10-01)Mixed layer depth (MLD) has long been recognized as having an important influence on underwater light budget and, thus, net primary productivity (NPP) of phytoplankton. The depth- and wavelength-integrated carbon-based ... -
Sensitivity of simulated wintertime Arctic atmosphere to vertical resolution in the ARPEGE/IFS model
(Journal article, 2008)The current state of the art general circulation models, including several of those used by the IPCC, show considerable disagreement in simulating present day high latitude climate. This is of major concern and reduces the ... -
The sensitivity of the present day Atlantic meriodinal overturning circulation to freshwater forcing
(Peer reviewed; Journal article, 2003-09-09)Mounting evidence indicates that the Atlantic Meridional Overturning Circulation (AMOC) was strongly reduced during cold climate episodes in the past, possible due to freshwater influx from glacial melting. It is also ... -
Simulated North Atlantic-Nordic Seas water mass exchanges in an isopycnic coordinate OGCM
(Journal article, 2003-05-29)The variability in the volume exchanges between the North Atlantic and the Nordic Seas during the last 50 years is investigated using a synoptic forced, global version of the Miami Isopycnic Coordinate Ocean Model (MICOM). ... -
Sources and upstream pathways of the densest overflow water in the Nordic Seas
(Journal article; Peer reviewed, 2020)Overflow water from the Nordic Seas comprises the deepest limb of the Atlantic Meridional Overturning Circulation, yet questions remain as to where it is ventilated and how it reaches the Greenland-Scotland Ridge. Here we ... -
Structure and drivers of ocean mixing north of Svalbard in summer and fall 2018
(Journal article; Peer reviewed, 2021)The Arctic Ocean is a major sink for heat and salt for the global ocean. Ocean mixing contributes to this sink by mixing the Atlantic- and Pacific-origin waters with surrounding waters. We investigate the drivers of ocean ... -
A surface ocean CO2 reference network, SOCONET and associated marine boundary layer CO2 measurements
(Peer reviewed; Journal article, 2019-07-12)The Surface Ocean CO2 NETwork (SOCONET) and atmospheric Marine Boundary Layer (MBL) CO2 measurements from ships and buoys focus on the operational aspects of measurements of CO2 in both the ocean surface and atmospheric ... -
Temporal and spatial variability of the sea surface salinity in the Nordic Seas
(Peer reviewed; Journal article, 2002-11-02)In this paper, the temporal and spatial variability of the sea surface salinity (SSS) in the Nordic Seas is investigated. The data include a Russian hydrographical database for the Nordic Seas and daily to weekly observations ... -
Thermodynamic controls of the Atlantic Niño
(Peer reviewed; Journal article, 2015-11-26)Prevailing theories on the equatorial Atlantic Niño are based on the dynamical interaction between atmosphere and ocean. However, dynamical coupled ocean-atmosphere models poorly simulate and predict equatorial Atlantic ... -
Toward an ice-free Barents Sea
(Peer reviewed; Journal article, 2017)Arctic winter sea ice loss is most pronounced in the Barents Sea. Here we combine observations since 1850 with climate model simulations to examine the recent record low winter Barents Sea ice extent. We find that the ... -
Variations of Mixed Layer Depth and Water Properties in the Norwegian Sea for the period 1949-1999
(Peer reviewed; Journal article, 2006-06-08)The mixed layer of the ocean and the processes therein affect the ocean’s biological production, the exchanges with the atmosphere, and the water modification processes important in a climate change per- spective. To provide ... -
Vertical structure and seasonal variability of the inflow to the Lofoten Basin inferred from high resolution Lagrangian simulations
(Peer reviewed; Journal article, 2019-11-13)The Lofoten Basin in the eastern Nordic Seas plays a central role in modifying the warm Atlantic Water inflow toward the Arctic Ocean. Here, the Atlantic Water experiences increased residence times, cooling, and substantial ...
