What if you you could scoop up a jar of seawater and use it to figure out what species were in that part of the ocean? Today we’re able to do that with a new scientific technique analyzing environmental DNA, or eDNA for short. In this episode, we talk to Ryan Kelly, an ecologist and lawyer at the forefront of eDNA research, about the technique itself, how it's changing what we can learn about the ocean, and how that might impact policy.
