NSF: An exploration of the direct and indirect effects of climatic warming on arctic lake ecosystems.


July 2016 - June 2021


This proposed research will complete a multi-year, whole-lake warming manipulation, to quantify the effects of future climate change on lake ecosystems in the Arctic. Regional climate and lake models will be coupled with biotic response to better understand the sensitivity of lakes to changing atmospheric conditions. The overall goals are to: (A) experimentally measure the effects of longer growing seasons on system production and community composition (e.g., from microbes to fish), (B) predict arctic lake temperatures with a coupled, high-resolution lake and regional climate model, and (C) extend the empirical and modeled data from the first two components, in combination with historical climate data and climate projections, to simulate surrounding lakes that range in volume, depth, and surface area. These efforts will allow better predictions of the effects of climatic warming at a broader spatiotemporal scale and improve conservation prioritization and decision-making. The proposed research will substantially improve understanding of climate change effects on arctic lake ecosystems and improve the ability to more precisely predict lake ecosystem responses to different climate change scenarios.
