Since 1980, the National Park Service has been monitoring the water quality of lakes and streams across Acadia. Today, a state of the art buoy in Jordan Pond enhances this monitoring effort by collecting over 1,400 measurements per day.

 

Project Summary

The NexSens CB-400S data buoy that is deployed in Jordan Pond during the ice-off season provides minute-by-minute information on multiple water quality features. Pairing the buoy with a weather station located on Jordan Pond House (located at the south end of the lake) provides a powerful tool for scientists to track changes within the lake in near real-time and identify potential causes of shifts in lake structure and function. In particular, we are interested in the drivers of the change in the Lake's transparency overtime. The insight provided by the data buoy will help park staff as they make management decisions to preserve water resources in Acadia for years to come. This project, sponsored by a generous gift from Canon U.S.A., is a collaborative effort between Acadia National Park, the University of Maine’s Climate Change Institute, and Friends of Acadia.
