The BSH operates a system of numerical models which are based on a variety
modules. The model is fully operational, model output is used for the marine
services offered by BSH, the monitoring of the marine environment and
for oceanographic analysis.
The circulation model gives daily forecast of currents, water levels,
temperature, salinity and ice coverage in the North Sea and Baltic Sea for a
3 day forecast period. The simulation are forced by actual weather information,
tidal waves and other waves entering from the Atlantic and fresh water input
from larger rivers.
A drift and dispersion model is available to assist the coast
guard during rescue operations of shipwrecked persons or after spills of harmful
substances into the sea. The dispersion model is able to distinguish between
oil, drifting objects, suspended material and soluable chemicals. An ecological
model is under development to be able to model the biochemical-physical interactions
and to make predictions on changes in the marine environment.
