Influence of the Southern Annular Mode on the sea ice-ocean system: the role of the thermal and mechanical forcing
Description :
The global sea ice-ocean model ORCA2-LIM is used to investigate the impact of the thermal and mechanical forcing associated with the Southern Annular Mode (SAM) on the Antarctic sea ice-ocean system. The model is driven by idealized forcings based on regressions between the wind stress and the air t...

Transient residence and exposure times
Author(s) :
Delhez, E. J. M.
Description :
The residence time measures the time spent by a water parcel or a pollutant in a given water body and is therefore widely used in environmental studies. The adjoint method introduced by Delhez et al. (2004) to compute this diagnostic is revised here to take into account the effect of the initializat...

Remote detection of water property changes from a time series of oceanographic data
Description :
A water mass analysis method based on a constrained minimization technique is developed to derive water property changes in water mass formation regions from oceanographic station data taken at significant distance from the formation regions. The method is tested with two synthetic data sets, design...

Detecting changes in Labrador Sea Water through a water mass analysis of BATS data
Description :
A new water mass analysis technique is used to analyse the BATS oceanographic data set in the Sargasso Sea of 1988?1998 for changes in Labrador Sea Water (LSW) properties. The technique is based on a sequential quadratic programming method and requires careful definition of constraints to produce re...

The circulation of the Persian Gulf: a numerical study
Description :
We employ a three-dimensional hydrodynamic model (COHERENS) in a fully prognostic mode to study the circulation and water mass properties of the Persian Gulf ? a large inverse estuary. Our findings, which are in good agreement with observational evidence, suggest that the Persian Gulf experiences a ...

Distributions of mixed layer properties in North Pacific water mass formation areas: comparison of Argo floats and World Ocean Atlas 2001
Description :
Winter mixed layer characteristics in the North Pacific Ocean are examined and compared between Argo floats in 2006 and the World Ocean Atlas 2001 (WOA01) climatology for a series of named water masses, North Pacific Tropical Water (NPTW), Eastern Subtropical Mode Water (ESTMW), North Pacific Subtro...

On the representation of regional characteristics by hydrographic measurements at central stations in four deep basins of the Baltic Sea
Author(s) :
Reissmann, J. H.
Description :
In this work the eddy resolving data sets of salinity, temperature, and oxygen content aquired in the framework of the German-Russian project MESODYN (MESOscale DYNamics) in the Arkona Basin, the Bornholm Basin, the Stolpe Furrow, and the Eastern Gotland Basin during summer and winter stratification...

Distribution of overwintering Calanus in the North Norwegian Sea
Description :
During winter 2003 and 2004, zooplankton and hydrographic data were collected in the northern parts of the Norwegian Sea (68?72° N, 8?17° E) west of the Norwegian shelf break at depths down to 1800 m. The results cover both inter and intra annual changes of hydrography and distribution of Calanus...

The assessment of temperature and salinity sampling strategies in the Mediterranean Sea: idealized and real cases
Author(s) :
Raicich, F.
Description :
Temperature and salinity sampling strategies are studied and compared by means of the Observing System Simulation Experiment technique in order to assess their usefulness for data assimilation in the framework of the Mediterranean Forecasting System. Their impact in a Mediterranean General Circulati...

Atmospheric forcing by ALADIN/MFSTEP and MFSTEP oriented tunings
Description :
ALADIN/MFSTEP is a configuration of the numerical weather prediction (NWP) model ALADIN run in a dedicated real-time mode for the purposes of the MFSTEP Project. A special attention was paid to the quality of atmospheric fluxes used for the forcing of fine-scale oceanographic models. This paper desc...
