Ecological study of gas fields in the northern Adriatic: 3.Surface waves

The paper deals with the surface wave data recorded in the area of gas field IVANA and IKA from 1978 to 1984 and partly from 1985 to 1986. It includes calculations of relative and cumulative frequencies of wave heights and periods and height distribution per seasons. Statistical analysis of the wave height, period and length was made for extreme speeds of characteristic winds, the Bora and Scirocco. The wave spectra were calculated from digitized records, with parameter approximation. Finally estimates of extreme values of significant wave heigths are given.
