Examination of one hundred thermographies of the Ligurian Sea, obtained during the years 1975, 1977, 1978 and 1979 by the satellite NOAA 5, reveals the quasi-permanence, over a year, of a mean superficial cyclonic circulation, generally characterized by its thermal pattern. The large number of satellite images and the use of specific methods permit the description of the annual variations in the structure of the horizontal thermal gradients. Results are in close agreement with those provided by previous authors.
