Ocean abyssal carbon experiments at 0.7 and 4 km depth
(Journal article, 2005)Observations from small-scale (20 to 90 litres) CO2 experiments conducted off the coast of California at 684 m depth and at 3942 m depth are discussed. In both experiments, when the seawater velocity was sufficiently strong, ... -
Convective chimneys and plumes in the Northern Greenland Sea
(Geophysical Monograph Series;30, Chapter, 2005)In the Boreas Basin in the northern Greenland Sea, convection has been observed to be localized as narrow structures - chimneys - in which the water masses may be homogeneous from the surface through great depths. An ... -
The red-sky enigma over Svalbard in December 2002
(Peer reviewed; Journal article, 2005)On 6 December 2002, during winter darkness, an extraordinary event occurred in the sky, as viewed from Longyearbyen (78° N, 15° E), Svalbard, Norway. At 07:30 UT the southeast sky was surprisingly lit up in a deep red ... -

Large-Scale Atmospheric Circulation Variability and its Impacts on the Nordic Seas Ocean Climate - a Review. In: The Nordic Seas: An Integrated Perspective
(Geophysical Monograph Series;158, Chapter, 2005)The large-scale atmospheric circulation and its impacts on the Nordic Seas ocean climate are reviewed. The dominant factors for the atmospheric variability are the Icelandic low and the Azores high, determining the strength ... -
Deep ocean experiments with fossil fuel carbon dioxide: creation and sensing of a controlled plume at 4 km depth
(Peer reviewed; Journal article, 2005-01)The rapidly rising levels of atmospheric and oceanic CO2 from the burning of fossil fuels has lead to well-established international concerns over dangerous anthropogenic interference with climate. Disposal of captured ... -
Intermediate water from the Greenland Sea in the Faroe Bank Channel : spreading of released sulphur hexafluoride
(Journal article, 2005-02)The Faroe Bank Channel is the deepest passage for dense water leaving the Nordic Seas into the North Atlantic. The contribution to this part of the Greenland-Scotland Overflow by intermediate water from the Greenland Sea ... -
The North Atlantic Oscillation and greenhouse-gas forcing
(Peer reviewed; Journal article, 2005-02-17)The results of 12 coupled climate models participating in the Coupled Model Intercomparison Project (CMIP2) are compared together with observational data in order to investigate: 1) How the current generation of climate ... -
The East Greenland Current studied with CFCs and released sulphur hexafluoride
(Journal article, 2005-03)The distribution and evolution of water masses along the East Greenland Current (EGC) from south of the Fram Strait to the Denmark Strait were investigated using chlorofluorocarbons (CFCs) and the released tracer sulphur ... -
Atmospheric boundary layers in storms: advanced theory and modelling applications
(Peer reviewed; Journal article, 2005-03-29)Turbulent planetary boundary layers (PBLs) control the exchange processes between the atmosphere and the ocean/land. The key problems of PBL physics are to determine the PBL height, the momentum, energy and matter fluxes ... -
Diurnal Circulation of the Bolivan Altiplano. Part I: Observations
(Journal article, 2005-04)In July and August 2003 a field campaign was conducted to explore the diurnal circulation of the Bolivian Altiplano. Vertical soundings by remote-controlled aircraft yielded profiles of temperature, pressure, and humidity ... -
Measured volume, heat, and salt fluxes from the Atlantic to the Arctic Mediterranean
(Journal article, 2005-04-07)The flow of warm and saline Atlantic water towards the Arctic crosses the Greenland-Scotland Ridge in three current branches. Since the mid 1990's, extensive monitoring with quasi-permanent moorings and regular CTD cruises ... -
Atmospheric icing and meteorological variables: Full scale experiment and testing of models

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 ... -
Numerical sensitivity studies on the variability of climate-relevant processes in the Barents Sea
(Peer reviewed; Journal article, 2005-06-03)The Barents Sea is a key region in the North Atlantic/Arctic Ocean climate system because of the intense ocean-atmosphere heat exchange and the formation of sea ice. The latter process is connected with salt input, so-called ... -
Estimating global radiation at ground level from satellite images

Direct measurements of the mean flow and eddy kinetic energy structure of the upper ocean circuletion in the NE Atlantic
(Journal article, 2005-07-19)The upper ocean circulation in the sub-polar northeast Atlantic has been a challenge to quantify due to strong and variable wind-forcing, and strong and variable deep currents that lead to large uncertainties in the use ... -

On radar imaging of current features: 1. Model and comparison with observations
(Journal article, 2005-07-22)A new radar imaging model of ocean current features is proposed. The simulated normalized radar cross section (NRCS) takes into account scattering from ‘‘regular’’ surfaces (by means of resonant Bragg scattering and specular ...
