Summary:Abstract Seabirds were observed during the southward (December 1989) and homeward (March 1990) voyage of the Ninth Indian Expedition to Antarctica. Twenty-four species were observed, with high diversity between 40° and 60° S. A smaller variety of species, but greater numbers, were observed between latitudes 60° and 70° S. The number of species increased in the zone of high primary and secondary production. Many species showed seasonal shifts in distribution.
