Interactive Datasets:

Long-Term Changes in Poconos Lakes
This R Shiny App was developed by Craig Williamson's Global Change Limnology laboratory at Miami University. This app enables users to visualize trends in abiotic variables (e.g. light (PAR and UV), temperature, oxygen) and zooplankton communities over 30 years, or see more recent changes in a variety of lake data collected using high frequency sensors.  The full dataset is archived as part of the Environmental Data Initiative. The development of this App was funded by NSF (DEB 1754276 and NSF DEB 1950170), a Lacawac Watres Student Research Award, and Miami University's Eminent Scholar funds.
