Short summary

The voyages of Cook (1772–1775) and Bellingshausen (1819–1821) were attempts to find a southern land mass. Sea ice blocked each voyage's southern probes, but sea ice and iceberg records were collected from around Antarctica. They show more northerly records of both forms of marine ice than today. The early Pacific sector of the Southern Ocean saw marine ice within the range of modern observations, but the Weddell Sea and Indian Ocean marine ice then extended further north than today.
