High-frequency sea level oscillations observed and modelled in the Split harbour (Adriatic Sea)

The paper deals with the high-frequency analysis based on the data of pressure gauge located in the Split harbour, collecting the data of sea and air pressure. The analysis included the spectral analysis and filtering, revealing harbour seiches having periods of 6.5, 3.0, 2.2, 1.6 and 1.15 min. The seiches were modelled and verified numerically. Furthermore, a strong peak was found on period of 11.9 min of air pressure data, highly correlated to the sea pressure with phase lag of about 90o and gain of about 14 cm/hPa.
