 In November 1903 Scotia retreated to Buenos Aires for repair and reprovisioning . While in Argentina , Bruce negotiated an agreement with the government whereby Omond House became a permanent weather station , under Argentinian control . Renamed Orcadas Base , the site has been continuously in operation since then , and provides the longest historical meteorological series of Antarctica . In January 1904 Scotia sailed south again , to explore the Weddell Sea . On 6 March , new land was sighted , part of the sea 's eastern boundary ; Bruce named this Coats Land after the expedition 's chief backers . On 14 March , at 74 ° 01 ′ S and in danger of becoming icebound , Scotia turned north . The long voyage back to Scotland , via Cape Town , was completed on 21 July 1904 .
