Connectivity among subpopulations of Norwegian Coastal cod. Impacts of physical-biological factors during egg stages.
(The University of Bergen, 2012-04-19)
Norwegian Coastal cod form a stationary population of Atlantic cod ( Gadus morhua L.) consisting of several genetically separated subpopulations. A small-scale differen- tiation in marine populations with pelagic ...
Turbulent diffusion and transport from a CO2 lake in the deep ocean
(American Geophysical Union, 2005-09-21)
If liquid CO2 is stored as a dense ‘‘lake’’ on the deep ocean floor, it is expected to dissolve in seawater. Ocean currents and turbulence can increase the net rate of CO2 release by several orders of magnitude compared ...
Eddy-resolving simulations of the Fimbul Ice Shelf cavity circulation: Basal melting and exchange with open ocean
Melting at the base of floating ice shelves is a dominant term in the overall Antarctic mass budget. This study applies a high-resolution regional ice shelf/ocean model, constrained by observations, to (i) quantify present ...
Some aspects of the work of V.W. Ekman
(Cambridge University Press, 2006-01)
The climatic conditions in theArctic, and observations of the wind-induced drift of ice made in connexion with Fridtjof Nansen’s Fram expedition, led to the discovery 100 years ago by Vilhelm Bjerknes’ pupil, V.W. Ekman, ...
Northern Hemisphere storminess in the Norwegian Earth System Model (NorESM1-M)
(Copernicus Publications, 2014-12-16)
Metrics of storm activity in Northern Hemisphere high- and midlatitudes are evaluated from historical output and future projections by the Norwegian Earth System Model (NorESM1-M) coupled global climate model. The European ...
On radar imaging of current features: 1. Model and comparison with observations
(American Geophysical Union, 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 ...
On the Influence of Small-Scale Topography on Dense Plumes, with a Special Focus on the Filchner Overflow Plume
(The University of Bergen, 2007-10-05)
Flow over a backward-facing step, a numerical study comparing a zand a σ-coordinate model
(Springer Verlag, 2011)
Homogeneous, nonrotating flow over a backward-facing rounded step is simulated using the 2D vertical version of two general circulation models, a z-coordinate model—the Massachusetts Institute of Technology general ...
Effects of simulated natural variability on Arctic temperature
(American Geophysical Union, 2005-09-23)
A five-member ensemble with a coupled atmospheresea ice-ocean model is used to examine the effects of natural variability on climate projections for the Arctic. The individual ensemble members are initialized from a 300 ...
A view on possible regime shifts in the North Atlantic subpolar gyre in the mid 1920s and 1990s
(The University of Bergen, 2014-10-22)
There is strong observational support for two significant warming episodes of the North Atlantic Subpolar Gyre (SPG), one starting in the mid 1920s the other in the mid 1990s. Possible mechanisms responsible for the two ...
