The Bulgarian Antarctic Program is implemented through the National Polar Base “St. Kliment Ohridski,” located on Livingston Island, part of the South Shetland Islands in Western Antarctica. Since 1993, the base has functioned as an active research center and an important logistical hub for Bulgaria’s presence on the Ice Continent.
Bulgaria’s first participation in Antarctic research dates back to 1967–1969, when Bulgarian scientists joined Soviet Antarctic expeditions. After a brief pause, the country resumed activities in 1987–1988 with a team of six Bulgarian scientists participating in a joint project with the Soviet Arctic and Antarctic Research Institute.
The first Bulgarian expedition involving the establishment of a permanent base took place in 1987–1988. Geologists Hristo Pimpirev, Borislav Kamenov, and Zlatil Velichkov, together with engineer Assen Chakurov and Dr. Georgi Popov, laid the foundations of “St. Kliment Ohridski.”
Over the years, the base has expanded, modernized, and established itself as a center for field research in multiple scientific disciplines.
Scientific Activity
Research conducted in the region of the base covers a wide range of scientific fields:
-
geology
-
biology
-
climatology
-
glaciology
-
oceanography
-
geomorphology
-
medicine
-
ecology
Studies are carried out on Livingston Island and neighboring areas of the South Shetland archipelago. To access remote areas after ski traverses, snowmobiles are used under strictly monitored glacier-safety protocols.
Logistics and Capacity
“St. Kliment Ohridski” Base operates between November and March and provides working conditions for up to 30 people.
In addition to laboratories and research facilities, the base includes:
-
a dining hall
-
a communication center
-
a medical room
-
modular residential units (built in 2008)
Bulgaria also operates the scientific research vessel RSV 421 “St. St. Cyril and Methodius,” which supports transportation and logistics between South America and Livingston Island, and provides research infrastructure for studies in the World Ocean.
