Integrated modelling and measurement of physically controlled fluxes and plankton dynamics in coastal seas

Objective

The project aims to advance physical aspects of marine environmental modelling through: 1) forming common North Sea and Mediterranean data sets with which existing 2-D shelf-sea hydrodynamic models will be forced, intercompared and tested; 2) measuring characteristic physical and phytoplankton variability in the Rhine outflow plume region in SeptemberOctober 1990, including HF radar mapping of surface currents, time-series moorings for currents, temperature, salinity, fluorescence and transmittance, and detailed ship surveys; 3) forming a framework and primitive modules for a new common model of physical and plankton behaviour in regions of freshwater influence, incorporating surface fluxes, shear, stratification, turbulence, waves, suspended sediment (a module will be developed) and plankton dynamics.
Various physical aspects of marine environmental modelling have been developed.
Common North Sea and Mediterranean data sets have been formed and used to force, intercompare and test existing 2-dimensional shelf and sea hydrodynamic models.

Characteristic physical and phytoplankton variability in the Rhine outflow plume region, Clyde Sea and Thermaikes Bay were measured, including high frequency (HF) radar mapping of surface currents, time series moorings for currents, temperature, salinity, fluorescence and transmittance, and detailed ship surveys.

A framework and primitive modules have been formed for a new common model of physical and plankton behaviour in regions of freshwater influence, incorporating surface fluxes, shear, stratification, turbulence, waves, suspended sediment and plankton dynamics.

A review has been carried out of processes at the edge of the continental shelf, and their contribution to circulation, mixing and especially ocean shelf exchange in relation to context (topography, winds, tides, etc).

A simple model with steady advection, diffusion and particle settling (only) has been used to relate cross shelf and slope distributions of suspended matter to relative values of diffusivities, settling velocity and particle sources including resuspension.
PROJECT DESCRIPTION:


The project aims to advance physical aspects of
marine environmental modelling through:
1) forming common North Sea and Mediterranean data
sets with which existing 2-D shelf-sea
hydrodynamic models will be forced,
intercompared and tested;
2) measuring characteristic physical and
phytoplankton variability in the Rhine outflow
plume region in September/October 1990,
including HF radar mapping of surface currents,
time-series moorings for currents, temperature,
salinity, fluorescence and transmittance, and
detailed ship surveys;
3) forming a framework and primitive modules for a
new common model of physical and plankton
behaviour in regions of freshwater influence,
incorporating surface fluxes, shear,
stratification, turbulence, waves, suspended
sediment (a module will be developed) and
plankton dynamics.
