A new method for estimating climatological temperature and salinity fields in the northern Adriatic from historic data

Valter Krajcar

Abstract

The climatological fields of temperature and salinity in the northern Adriatic were determined by a new method. The fields were estimated using a large quantity of hydrographic data collected at 45 stations by the Center for Marine Research, Rudjer Bošković Institute, Rovinj, in the second half of the twentieth century, and the MEDATLAS hydrographic database. In the new method, four
matrices of coefficients were extracted from the data using empirical eigen functions, Principal Component Analysis, and multiple regression. The coefficients were used to synthesize the fields. Figures showing monthly sea surface temperature and salinity in the northern Adriatic are presented. The method, with some modifications, could be used to determine climatological fields of other sea parameters (e.g., nutrients) or scientific fields (e.g., meteorology).
