Correlation between damping of sea ripples and other physico-chemical properties in coastal marine water

Rheological data of the marine surface obtained from frequency wave spectra are compared with physico-chemical analyses of water samples drawn simultaneously from half a meter below the interface in fifteen preselected locations along a stretch of Tuscan Coast located between the Arno and Serchio rivers. The study has proved the presence of adsorption films tightly related to the rivers' plumes. A good correlation between the anionic surfactants detected in gas-bubble-enriched samples and the adsorbent excess measured at the surface has been observed. Implications of the multifrequency radar remote-sensing technique are here discussed. © 1994 Società Italiana di Fisica.
