Eklund Islands: A Remote Archipelago of the Antarctic Peninsula
Tucked away near the southwest end of George VI Sound, the Eklund Islands represent a stark example of the dynamic nature of the Antarctic landscape. These islands, located toward the south of the Antarctic Peninsula, are characterized by their emergence through thick ice, serving as a testament to the rigorous exploration of one of Earth's most inhospitable regions.
Key Facts
- Location: Southwest end of George VI Sound, Antarctic Peninsula (73°16′S 71°50′W).
- Discovery: First sighted in December 1940 by Finn Ronne and Carl R. Eklund.
- Largest Island: Approximately 5 nautical miles (9 km) in extent, reaching an elevation of 410 metres (1,350 ft).
- Composition: A group of islands that are primarily ice-covered.
- Naming: Named after Carl R. Eklund, an ornithologist and assistant biologist.
The History of Discovery
The Eklund Islands were first encountered in December 1940 during a grueling expedition by the United States Antarctic Service. Explorers Finn Ronne and Carl R. Eklund undertook a massive 1,097-mile (1,765 km) sledge journey, traveling south from Stonington Island to the southwest reaches of George VI Sound and back.
During this initial journey, Ronne identified a single large landmass protruding above a field of hummocky ice (ice characterized by irregular mounds or ridges). Ronne named this specific island after his companion, Carl R. Eklund, who served as the expedition's assistant biologist and ornithologist.

From a Single Island to an Archipelago
For nearly a decade, the area was believed to contain only one significant piece of exposed land. However, the geography of the region was redefined in 1949 when V. E. Fuchs and R. J. Adie of the Falkland Islands Dependencies Survey conducted their own sledge journey to the southwest part of the sound.
Due to a recession of the ice in George VI Sound, Fuchs and Adie discovered that the landmass identified by Ronne and Eklund was actually the largest member of a larger group of islands. Most of these surrounding islands remain heavily ice-covered, making them difficult to detect without significant ice retreat.
Following this discovery, the Advisory Committee on Antarctic Names recommended that the name "Eklund" be applied to the entire island group rather than just the single largest island.

Frequently Asked Questions
Who are the Eklund Islands named after?
The islands are named after Carl R. Eklund, who was the assistant biologist and ornithologist for the United States Antarctic Service expedition in 1940.
Where exactly are the Eklund Islands located?
They are located at 73°16′S 71°50′W, situated near the southwest end of George VI Sound toward the south of the Antarctic Peninsula.
How was the island group discovered?
The largest island was discovered in December 1940 during a 1,097-mile sledge journey from Stonington Island. The full group of islands was later identified in 1949 after ice recession revealed more land.
What is the size of the largest island in the group?
The largest island extends approximately 5 nautical miles (9 km) and reaches a height of 410 metres (1,350 ft).
Why was the naming of the islands changed?
Originally, only one island was visible. Once the Falkland Islands Dependencies Survey determined that it was part of a larger group of ice-covered islands, the name was expanded to cover the entire archipelago.
