Under thinning ice at Lake Fryxell

Date: 2023
Type: Update
Summary: In January, divers were able to return to the bottom of Lake Fryxell in the McMurdo Dry Valleys. Waikato University professor Ian Hawes donned his dive suit as part of a NZ-US team carrying out long-term ecological monitoring. They found that the ice on the lake is thinning, and this is changing the microbial life that grows in this extreme environment. Videographer Anthony Powell worked with the divers to bring back pictures from the bottom of the lake, and TVNZ's Laura Frykberg helped tell the story.
