On World Oceans Day the International Association of Antarctica Tour Operators reaffirmed its commitment to protecting the Southern Ocean by announcing the establishment of a new voluntary Geofenced Whale Area around the South Orkney Islands beginning in the 2026/27 Antarctic season.
This new operational measure is designed to reduce the risk of whale strikes in an area increasingly recognised as an important habitat for recovering whale populations. IAATO members operating within the designated area will voluntarily observe a 10-knot speed restriction, measured as "speed over ground," between Nov. 1 and May 30. The measure will remain in place for an initial two-year period or until further review by the IAATO Marine Committee.
The South Orkney Islands, located approximately 370 miles/600 kilometers northeast of the Antarctic Peninsula, are the latest addition to IAATO's growing network of Geofenced Whale Areas, first introduced in 2019 in the Gerlache Strait and Crystal Sound. Since then, IAATO has expanded and refined the program by adding mandatory whale protection areas around the South Shetland Islands and Elephant Island, and by introducing an Acoustic Awareness Zone in the Gullet.
"World Oceans Day is a reminder that protecting marine ecosystems requires both collaboration and action," said Maureen Lynch, IAATO's science and monitoring senior manager.
"Establishing this new Geofenced Whale Area reflects IAATO members' ongoing commitment to evidence-based operations that help safeguard wildlife while contributing to broader ocean conservation efforts."
The decision — approved by IAATO members at the association's annual meeting in April — follows increasing scientific evidence demonstrating high whale occurrence in the region. IAATO's Voluntary Cetacean and Pinniped Sightings Program has documented 203 whale observations across four Antarctic seasons from vessels operating near the islands, including 82 humpback whales and 76 fin whales, alongside sei whales and killer whales.
An important driver of this initiative was survey data collected by longtime Antarctic expedition leader and whale scientist Ted Cheeseman and colleagues during a research expedition from February to March this year This expedition recorded 1,468 individual whales of six species in the area over an 18-day survey, with large concentrations of humpback and fin whales observed in nearshore waters north of the islands and offshore areas to the south. Southern right whales have also been documented through both dedicated surveys and community science platforms, including Happywhale and iNaturalist.
The findings underscore the ecological significance of the area for multiple whale species and have helped inform efforts to enhance their protection.
Cheeseman, the founder of Happywhale, said: "The South Orkney Islands are like an oceanic Serengeti for whales, an under-appreciated gem," adding: I am deeply grateful for IAATO's forward-looking action to keep whales safe by managing vessel speeds in these waters, a fantastic act of stewardship of the Antarctic environment."
