The British sea captains William Smith and Edward Bransfield, in the brig Williams, and the Russian captain Thaddeus Bellingshausen, in Vostok and Mirnyy, have also been credited with the first sighting of the Continent [sic; his discovery was almost a year later than the Bellingshausen and Bransfield sightings].


The Peninsula was previously known by different names in different countries (Palmer Peninsula to the United States). In 1964, the United States and United Kingdom aggreed to call it the Antarctic Peninsula; subsequently, several other Treaty nations have accepted this name.


In September 1965 and August 1966, reconnaissance flights were made over the Bransfield and Gerlache Straits and as far south as the Argentine Islands to examine winter sea-ice conditions (Smith, 1966). Observations indicated that Hero probably could work safely in these waters during the winter, but that difficulty would be encountered making a passage to South America through the wide belt of pack ice north of the South Shetland Islands. Hence, there are no immediate plans for Hero to remain in Antarctic waters in the winter.
