This paper includes information on the trend of the elephant seal population at Stranger Point (25 de Mayo-King george I.) between 1980-87(excluding 1981). A decline in the population was observed in 1980-82 and 1987. The female component was mainly affected in 1 980-82 (r=-0.568) while the male component was affected in 1987 (r=-0.463). A possible influence of El Niño Southern Oscillation (ENSO) events upon the numerical changes in the studied population is postulated.
