An automatic meteorological and oceanographic pilot system based on "Aanderaa" sensors has been installed on the Cape of Marjan Peninsula close to Institute. Special software for data transmission and presentation on Internet has been developed. All the measurements are registered into the database and are automatically presented in graphic form. Except for the momentary data (measurements are carried out every 10 min), on the Institute's web pages are available various graphic surveys of measured data. Also, the measurement is intended to be input parameters for non-linear levels model for calculations of wind-driven circulation on the Kastela bay. Software for visualization and web presentation of numeric model results will be developed too (until beginning of the September).
