An analysis of diffusion characteristics in the harbour area (Split harbour, Adriatic Sea)

An experiment, including measurements of physical, chemical and biological properties, was conducted in the Split harbour area (Middle Adriatic) in order to investigate the diffusion there. After the tracer (RHODAMINE-B) had been ejected into the sea, the oil spill was followed using three theodolites from the land and by photographing the area. The horizontal diffusion coefficient, calculated from the simple one-dimensional Okubov model, had values between 0.3 and 1.1 cm/s. Seasonally, the diffusion coefficient had higher values during summertime, while during winter it had lower values as a result of the influence of current field.
