Film: A Love Letter to Alaska

This summer, Erica Prather and Andy Davidson, naturalist guides in Juneau, Alaska, decided that the Tongass National Forest—a coastal temperate rainforest which boasts one of the highest biomass productions in the world—would be an ideal spot to focus on freshwater microplastic studies for Adventurers and Scientists for Conservation.

The Tongass National Forest is the largest national forest in the United States, as well as Earth’s largest remaining temperate rainforest. With its famed ice caves and ancient glacial melt, it encompasses the entire Mendenhall Glacier.

The team took samples in the ice caves of Mendenhall Glacier, in the Mendenhall River after glacial melt had moved through Juneau’s residential area, and Salmon Creek, where salmon spawn each summer. 

Upon their return, Erica and Andy made this inspiring video that captures the very essence of this project.
