Researchers probe how much sulfide Puget Sound eelgrass can withstand

What’s green, thin, slimy and sways in the water?

It’s eelgrass, an often unseen marine plant that is important for the environment and economy in the Puget Sound region.

The eelgrass in Puget Sound is sort of like a canary in a coal mine for the underwater world, serving as an indicator of marine health. It can affect many species that depend on it, from crabs to salmon.
