The Apostle Islands National Lakeshore in southwestern Lake Superior is composed of 21 of the archipelago's 22 islands. This park is included in all of our programs except for annual water quality monitoring because there are no inland lakes on any of the islands. Special projects (including some water quality monitoring) do occur in the Lake Superior part of the park, though, and the islands are revealing themselves to be a gathering place for microplastics.

Dragonfly Mercury Project

As a foundational part of the aquatic food web, dragonfly larvae we collect each summer are tested for mercury in the environment, which helps us understand mercury contamination at higher levels of the food web.
