Chile’s Yelcho Antarctic Base Marks 63 Years as a Hub for Polar Research

The Chilean Antarctic base Yelcho, managed by the Chilean Antarctic Institute (INACH), celebrated its 63rd anniversary, emphasizing its critical role as a natural laboratory for polar research.

Located on Doumer Island in the Palmer Archipelago at 64 degrees south latitude, the base has become a cornerstone for studying marine biodiversity, environmental monitoring, and climate change impacts in Antarctica.

David Domenech, head of the Yelcho base, highlighted its strategic location and unique environment as pivotal for advancing scientific knowledge. He noted that the area’s rich marine species diversity, air quality characteristics, and local fauna contribute to its importance.

This makes it an essential hub for multidisciplinary studies. Currently, the station supports 17 personnel, including nine logistical staff and eight researchers conducting projects funded and coordinated by INACH.

However, this season’s research initiatives include installing monitoring stations as part of the Antarctic Climate Change Observatory Sensor Network, analyzing pollution sources, and studying intertidal ecosystems.

The base also facilitates scientific diving operations to collect marine species for the International Antarctic Center and supports a University of Santiago project investigating snow samples, photogrammetry, and red algae monitoring.

With a capacity to host up to 27 people, Yelcho has undergone infrastructure upgrades to enhance its laboratory spaces and human capacity. Additional improvement projects are under evaluation to further expand its capabilities.

Founded in 1962 by the Chilean Navy and transferred to INACH in 1986, the base operates under Chile’s Antarctic Policy, focusing on excellence in scientific research and active participation in the Antarctic Treaty System.

Yelcho’s name honors the vessel commanded by Luis Pardo Villalón, who led the 1916 rescue of Sir Ernest Shackleton’s stranded crew on Elephant Island.

INACH continues to strengthen Magallanes’ role as a gateway to Antarctica by promoting awareness of Antarctic science among local communities while fostering international collaboration.
