Evaluation of ocean carbon cycle models with data-based metrics
(American Geophysical Union, 2004-04-02)
New radiocarbon and chlorofluorocarbon-11 data from the World Ocean Circulation Experiment are used to assess a suite of 19 ocean carbon cycle models. We use the distributions and inventories of these tracers as quantitative ...
Using the Extended Kalman Filter with a Multilayer Quasi-Geostrophic Ocean Model
(American Geophysical Union, 1992-11-15)
The formulation of the extended Kalman filter for a multilayer nonlinear quasi-geostrophic ocean circulation model is discussed. The nonlinearity in the ocean model leads to an approximative equation for error covariance ...
Evaluating Global Ocean Carbon Models: The Importance of Realistic Physics
(American Geophysical Union, 2004-09-15)
A suite of standard ocean hydrographic and circulation metrics are applied to the equilibrium physical solutions from 13 global carbon models participating in phase 2 of the Ocean Carbon-cycle Model Intercomparison Project ...
Arctic sea ice and climate change - will the sea ice disappear in this century?
(Blackwell Scientific Publications, 2000)
Cover ERS-1/2 SAR monitoring of dangerous ice phenomena along the western part of Northern Sea Route
(Taylor & Francis, 1997-08-01)
High-frequency internal wave observations in the marginal ice zone
(American Geophysical Union, 1987-06-30)
Open Boundary Conditions for the Extended Kalman Filter With a Quasi-Geostrophic Ocean Model
(American Geophysical Union, 1993-05-18)
The formulation of consistent boundary conditions for the quasi-geostrophic (QG) model with an extended Kaiman filter in a data assimilation scheme is discussed. To form a well-posed boundary value problem for the QG model, ...
The greater Agulhas Current system: an integrated study of its mesoscale variability
(The Institute of Marine Engineering, Science & Technology (IMarEST), 2008-02)
For the purpose of developing an operational oceanography system for the greater Agulhas Current regime, a high resolution Hybrid Coordinate Ocean Model (HYCOM) has been set in a nested configuration. The intense and complex ...
Ocean data assimilation systems for GODAE
(The Oceanography Society, 2009-09)
Ocean data assimilation has matured to the point that observations are now routinely combined with model forecasts to produce a variety of ocean products. Approaches to ocean data assimilation vary widely both in terms ...
Annual cycles of sea level and sea surface temperature in the western Mediterranean Sea
(American Geophysical Union, 2003-03-01)
In the western Mediterranean Sea, sea level variations are the result of seasonal steric effect, atmospheric forcing and mesoscale circulation activity, particularly in the Alboran and Algerian basins, as well as water ...
