the conditions were practically
unknown, resulting in the discovery of new lands and islands.

2. Journeys were made over the sea-ice and on the coastal and upland
plateau in regions hitherto unsurveyed. At the Main Base (Adelie
Land) the journeys aggregated two thousand four hundred miles, and at
the Western Base (Queen Mary Land) the aggregate was eight hundred
miles. These figures do not include depot journeys, the journeys of
supporting parties, or the many miles of relay work. The land was
mapped in through 33 degrees of longitude, 27 degrees of which were
covered by sledging parties.

3. The employment of wireless telegraphy in the fixation of a
fundamental meridian in Adelie Land.

4. The mapping of Macquarie Island.

Oceanography

1. By soundings the fringe of the Antarctic Continent as well as the
Continental Shelf has been indicated through 55 degrees of longitude.

2. The configuration of the floor of the ocean southward of Australia
and between Macquarie Island and the Auckland Islands has been broadly
ascertained.

3. Much has been done in the matter of sea-water temperatures and
salinities.

An Historical Summary**

** For this compilation reference has been largely made to Dr. H. R.
Mill's "The Siege of the South Pole." Several doubtful voyages
during the early part of the nineteenth century have been omitted.

1775. James Cook circumnavigated the Globe in high southern
latitudes, discovering the sub-antarctic island of South Georgia.
He was the first to cross the Antarctic Circle.

1819. William Smith, the master of a merchant vessel trading between
Montevideo and Valparaiso, discovered the South Shetland Islands.

1819. Fabian Gottlieb von Bellingshausen, despatched in comm
