The impact of ensemble filter definition on the assimilation of temperature profiles in the tropical Pacific
(Royal Meteorological Society, 2005-10)
The traditional analysis scheme in the Ensemble Kalman Filter (EnKF) uses a stochastic perturbation or randomization of the measurements which ensures a correct variance in the updated ensemble. An alternative so called ...
Two-phase, near-field modeling of purposefully released CO2 in the ocean
(American Geophysical Union, 2001-01-15)
Tracer-derived transit time of the waters in the eastern Nordic Seas
(Blackwell Munksgaard, 2005-08-25)
The spatial-temporal distribution of the anthropogenic radionuclide 137Cs originating from nuclear bomb testing and the Sellafield reprocessing plant in the Irish Sea is simulated using a global version of the Miami Isopycnic ...
Inception of the Northern European Ice Sheet due to contrasting ocean and insolation forcing
About 115,000 years ago the last interglacial reached its terminus and nucleation of new ice sheet growth was initiated. Evidence from the northernmost Nordic Seas indicate that the inception of the last glacial was ...
Mesoscale Eddies Are Oases for Higher Trophic Marine Life
(Public Library of Science, 2012-01-17)
<p>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 ...
Arctic/Atlantic exchanges via the Subpolar Gyre
(American Meteorological Society, 2012)
In the present study we investigate the decadal variability in the strength and shape of the Subpolar Gyre (SPG) in a 600-year pre-industrial simulation using the Bergen Climate Model. The atmospheric influence on the ...
A Possible Feedback Mechanism Involving the Arctic Freshwater, the Arctic Sea Ice, and the North Atlantic Drift
(Science Press, 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 ...
Arctic sea ice and climate change - will the sea ice disappear in this century?
(Blackwell Scientific Publications, 2000)
Gas exploration beyond the shelf break : an oceanographic challenge
<p>Norway's second largest gas field, Ormen Lange, is located 140 km west off Kristiansund at an unprecedented depth when it comes to exploration. It will be the first Norwegian project beyond the shelf break. Exploration ...
Direct ocean surface velocity measurements from space: Improved quantitative interpretation of Envisat ASAR observations
(American Geophysical Union, 2008-11-29)
Previous analysis of Advanced Synthetic Aperture Radar (ASAR) signals collected by ESA’s Envisat has demonstrated a very valuable source of high-resolution information, namely, the line-of-sight velocity of the moving ...
