Caption: Global map of mean wave heights. The map shows the mean height of ocean waves over the period 25 September to 4 October 1992, autumn in the northern hemisphere. Wave heights are colour coded, from magenta (less than 1 metre) through blue, green and yellow to red (7-8 metres). The largest waves are in the south Indian Ocean and the Southern Ocean near Antarctica, and are typical of the season (southern winter/spring). The data for this image were gathered by the TOPEX/Poseidon satellite in orbit 1336 km above the Earth using a radar altimeter.
