About the possibility of registration of waves and sea level fluctuations in coastal areas of the World Ocean based on analysis of video on the Internet

Abstract

The paper describes a technology of recording surface wave signals and sea level fluctuations in coastal areas of the World Ocean based on real-time analysis of live video from surveillance cameras presented on the Internet. A wave signal obtained with described method in the port of Crotone (Italy) is compared with data from nearby station of the Global Sea Level Observing System (GLOSS). The example demonstrates the high recording quality of the seiche oscillation system of the port with periods from 40 to 2 minutes, which is comparable to GLOSS. At the same time, unlike the GLOSS stations, signals obtained through video contain responses of even shorter-period (up to tens of seconds) seiches, swell waves, wind and ship waves.
