Hidden Below: The Great Lakes

@hiddenbelow.bsky.social

A wildlife documentary revealing the hidden lives of Great Lakes fish, birds, and mammals, all filmed with underwater robots.

While most Coaster Brook Trout spawn in rivers, researchers and Indigenous knowledge holders have long suggested that some may also spawn among Lake Superior's outer islands. Armed with this knowledge and a Parks Canada collaboration, we captured what is believed to be the first documented footage.

Yvonne has been named a recipient of the 2026 Wayfinder Award Presented by Kia from National Geographic Society. 💛🌎 The timing couldn't be more meaningful - this week we explored Superior Maximus, the deepest point in the Great Lakes. Now we're carrying that momentum into "Hidden Below"!

With just one day to go until our livestream, meet Kiyi, our ROV, affectionately named after the mysterious deepwater fish found only in Lake Superior. As we attempt to reach depths of more than 400 metres, Kiyi will be our eyes in the immense darkness, exploring a world few people have ever seen.

The deepest point in the Great Lakes is about to be explored LIVE. Come along on the search for deepwater sculpin, giant siscowet trout, colourful hydra, and perhaps even the elusive kiyi- never photographed alive in its natural habitat. Planned live dive: June 6 at 1 PM Weather window: June 6–9
