Evaluating two numerical advection schemes in HYCOM for eddy-resolving modelling of the Agulhas Current
(Copernicus Publications on behalf of the European Geosciences Union, 2009-06-02)
A 4th order advection scheme is applied in a nested eddy-resolving Hybrid Coordinate Ocean Model (HYCOM) of the greater Agulhas Current system for the purpose of testing advanced numerics as a means for improving the model ...
The European gravity field and steady-state ocean circulation explorer satellite mission: its impact on geophysics
(Kluwer Academic Publishers, 2003-07)
Current knowledge of the Earth’s gravity field and its geoid, as derived from various observing techniques and sources, is incomplete. Within a reasonable time, substantial improvement will come by exploiting new approaches ...
The Atlantic Water flow along the Vøring Plateau: Detecting frontal structures in oceanic station time series
The topographic steering of the baroclinic western branch of the Norwegian Atlantic Current (NwAC) determines the extent of Atlantic Water and location of the Arctic Front in the Nordic Seas. In this paper the geographical ...
Climate change in the North – past, present and future
(International Union of Geological Sciences (IUGS), 2008-03)
The Nordic countries have produced famous polar explorers and researchers who have generated climate research schools at a variety of locations. The dependence of these countries with respect to the lifelihood of their ...
Dr. Stein Sandven of NERSC on Arctic Regional Ocean Observing Systems

Characterizing chaotic dispersion in a coastal tidal model
Abstract Diverse Lagrangian methods are used to study dispersion and mixing in a model in the Norwegian Trondheim fjord. We focus on the tidally driven currents, neglecting wind-forcing, and generate a large number of ...
Parameter Estimation Solving a Weak Constraint Variational Formulation for an Ekman Model
(American Geophysical Union, 1997-06-15)
A weak constraint variational formulation is used for inverse calculations and parameter estimation in a one-dimensional Ekman model. When parameters in the model are allowed to contain errors, the inverse problem becomes ...
Observation and Simulation of Ice Tongues and Vortex Pairs in the Marginal Ice Zone
(American Geophysical Union, 1994)
Recognizes the major advancements of the past decade in understanding the interactions among the polar oceans and global atmospheric and oceanic systems. This volume addresses the following topics: Polar Ocean Circulation ...
Sea ice monitoring in the Arctic using satellite SAR images
(Luleå University of Technology and NERSC, 2007)
