Our field crews installed/updated two environmental monitoring stations in remote locations in the Pacific Northwest. Multiple types of sensors were installed including air and soil temperature, precipitation, soil moisture and soil redox potential. These stations provide data for designing and evaluating soil remediation projects for U.S. Environmental Protection Agency’s Office of Research and Development.

They provide food and shelter for aquatic life, including seahorses, turtles, thousands of species of fish, and more. In addition, they are amazing carbon sequesters, meaning they absorb atmospheric carbon reducing greenhouse gases. On World Seagrass Day, we…
