Karst and climate change: Understanding linkages between climate, water resources, and ecosystems
In this project researchers are assessing the links between climate, groundwater storage, spring flow, and ecosystem response in two contrasting major U.S. karst systems: the Edwards and Madison aquifers. Karst aquifers are uniquely suited for investigating effects of climate variability at timescales of human interest because they are highly dynamic; further, many provide habitat for rare and endangered species. The principal objective of this project is to determine how interrelations between karst hydrology and ecosystems will be affected by climate change. Current relations between recharge (impulse) and storage and spring flow (response) are quantified through signal-processing models that use existing...

ScienceBase brings together the best information it can find about USGS researchers and offices to show connections to publications, projects, and data. We are still working to improve this process and information is by no means complete. If you don't see everything you know is associated with you, a colleague, or your office, please be patient while we work to connect the dots. Feel free to contact sciencebase@usgs.gov.
