Belgrano II Station Argentine Antarctic Base

Belgrano II is Argentina’s most southerly year-round station, planted on a nunatak at the edge of the Filchner Ice Shelf in the Weddell Sea sector. Established in 1979, it sits at around 77°S — deeper south than almost any other permanently staffed base. A skeleton winter crew keeps it alive year-round. The station handles weather data, geomagnetic research, and logistics for Argentine deep-field operations. Resupply runs are infrequent, handled by Argentine naval vessels and occasional aircraft from Marambio Station.

Getting here is no casual detour. Icebreaker transit through the notoriously difficult Weddell Sea pack ice is the primary access route. Nearest staging point is Marambio Station on Seymour Island, itself roughly 1,400 km north. All access is through the Argentine Antarctic Program (DNA/IAA). Not for independent operators — but knowing it exists matters when planning deep Weddell corridor routes.

Argentina's southernmost permanent foothold.
