Sažetak
All historical data of classical oceanographic parameters (temperature, salinity, oxygen, and pH) stored in Marine Environmental Database of the Adriatic Sea (MEDAS) have been analysed. Since main figure of data distribution is not regular in space and time it was necessary to estimate the value of the each parameters at the nodes of an interpolated grid. All parameters were interpolated on the standard oceanographic levels, and the semivariogram graphs were used to describe the structural properties of field of each parameter. Geostatistics was used for interpolation of data because it estimates values correspond to the average values of the random function with minimum standard deviation error of interpolated data. GIS technique was used for the final analyze and presentation of output data (seasonal, monthly, yearly data distributed in different layers of water column and different sub regions of the Adriatic Sea). In addition, overlaying of different oceanographic parameters maps shows an influence of climate and environmental change on biodiversity in the Adriatic Sea.
