Sobral Scientific Base ( Base Base Científica Sobral or Base Sobral) was a permanent, all year-round and now only partially active Argentine Antarctic base and scientific Research Station located on the Filchner Ice Shelf at 81°04′05″South, 40°36′01″West. It bears its name in honor of the late 19th and early 20th century Argentine explorer Ensign José María Sobral, who had joined Dr. Otto Nordenskjöld’s ill-fated Swedish Antarctic expedition in 1903.

After 23 days of exploration, using nine days to go and four to return, they successfully returned to the Belgrano II leaving written testimonies in plastic tubes and marking the path with reeds and banners. After 14 years of this last reactivation, it was not possible to find it in 1997 when a patrol of 4 men from Belgrano II Base went in search of it. That patrol identified the place where the base should be located and established fuel depots for future operations in the region.
On 10 October 2000 a six-men research expedition established a scientific camp at Sobral’s emplacement and measured local ozone levels with a spectrophotometer. The temporary occupation was conducted by personnel belonging to Belgrano II and a technician from the National Antarctic Directorate; since then, a new expedition is sent every year between September and December, where the lowest annual average concentration of ozone in Antarctica is recorded.
