The Place

The Argentine island of Isla de los Estados lies 29 kilometers off the eastern extremity of Tierra del Fuego, aptly nicknamed the “End of the World.”

Named by Dutch explorers that encountered the island in 1615, Isla de los Estados has been protected both by its remoteness and its status as a nature reserve. Sitting at the eastern entrance to the Beagle Channel, the island has historically served as a station for seal hunters, a military prison, and a naval base, and is said to have provided the setting for Jules Verne’s novel The Lighthouse at the End of the World.

Far from its history as a seal-hunting outpost, Isla de los Estados today holds important feeding grounds for a variety of marine mammals, including the South American sea lion. Colonies of King, Magellanic, and rockhopper penguins can also be found on the island. The sea floor around the region is riddled with canyons and seamounts that are home to many endemic species of marine life, and giant kelp forests constitute a large part of this wild ocean ecosystem, harboring abundant biodiversity within and below their canopies.

The Pristine Seas team partnered with Argentina’s Ministry of Environment and Sustainable Development, Argentina’s National Parks Administration, the Government of Tierra del Fuego, and the Forum for the Conservation of the Patagonian Sea to carry out an expedition to Isla de los Estados and conduct comprehensive surveys of the health of this region’s marine environment.

The Mission

Over the course of this two-week expedition, the Pristine Seas team traveled from the port of Ushuaia through the Beagle Channel, along the southern coast of Argentina’s Tierra del Fuego, and around Isla de los Estados. Their aim was to study and film the marine ecosystems in this area, which is known to hold great biodiversity and an abundance of vulnerable and threatened species.

To achieve a comprehensive survey of the environment, the team made scuba dives to depths of up to 30 meters, used remote underwater video and open-water cameras, and deployed deep-sea drop cams to depths of over 2,000 meters.
