She’s pushed farther into deep underwater caves than any woman before her. Now, explorer Jill Heinerth is kicking off this year’s Royal Canadian Geographical Society Speaker Series with a talk about diving the caves in Antarctica’s icebergs.

Heinerth, who received the Society’s 2013 Sir Christopher Ondaatje Medal for Exploration, will share tales of what life is like in one of the coldest places in the world, including how she spent days around icebergs and the wildlife that lurks beneath them. The event takes place on April 30 at the Canada Aviation and Space Museum in Ottawa.

Heinerth joins the ranks of prominent past speakers, including Angry Planet host George Kourounis, wildlife photographer Paul Nicklen and climatologist David Phillips.

Although she used to have a successful career in graphic design and advertising, Heinerth traded her business suit for a wetsuit and became a worldrenowned cave diver.

Combining her technical and artistic skills, she’s made documentaries for PBS and the Discovery Channel, her photography has been published in magazines and newspapers, and she has written three books on cave diving and underwater photography.
