Learn about decreasing ice cover and profound changes to mountain lakes. Join in person or on Zoom.
Join Steven Fradkin, Olympic National Park (ONP) Coastal Ecologist and Limnologist, and Bill Baccus, ONP Physical Scientist, for their talk "The Influence of Changing Winter Conditions on Olympic Mountain Lakes."
Mountain lakes are ecologically important and charismatic features of the high country of the national parks of the North Coast and Cascades Network (Olympic, Mount Rainier, North Cascades). These lakes are ice-free approximately 5 months of the year. The remainder of the year they are locked under a thick blanket of ice and snow that limits the amount of light, atmospheric gas exchange, nutrient dynamics, and the pace of biological activity. As the global climate changes due to warming, the duration of winter ice cover is expected to decrease with potentially profound changes to these fragile ecosystems. We present a long-term dataset (up to 16 years) of ice duration from 21 NCCN lakes. This period of record illustrates changes in ice duration and includes examples of conditions expected in a near-future warmed world.
