In 1903 Dr William S. Bruce's Scottish National Antarctic Expedition established Omond House, a meteorological station on Laurie Island.

[2] Bruce left the station in December of that year for Buenos Aires to fix the ship and obtain supplies, leaving meteorologist Robert C. Mossman in charge of the base to continue the observations.

On 29 December, Haggard sent a note to the Argentine Foreign Minister, José Terry, ratifying the terms of Bruce's proposition.

[4] Roca submitted the matter to the Oficina Meteorológica Nacional (National Office of Meteorology) who advised him to accept the offer.

In 1906, Argentina communicated to the international community the establishment of a permanent base on the South Orkney Islands.

On August 26, Haggard sent a letter to Foreign Minister Manuel Montes de Oca reminding him that South Orkneys Islands were British.

[4] On March 30, 1927, naval non-commissioned officer Emilio Baldoni established the first radio telegraph link with Ushuaia.

Up to that point, the Orcadas Base remained isolated from the rest of the world until the yearly relief arrived.

[7] In contrast, when low pressure systems pass to the north, it results in cold and dry conditions with good visibility, causing temperatures to fall to −44.0 °C (−47.2 °F).

[7] Being located in the path of low pressure systems throughout the year, the base experiences high cloud cover, particularly in summer.

[7] Orcadas Base is the site of the Destacamento Lighthouse, a navigation light mounted on a communications tower.
