Exploring Deepwater Ecosystems with eDNA

A team of ocean scientists and engineers from Lehigh University and Woods Hole Oceanographic Institution are developing revolutionary new ways to study the biodiversity of deepwater ecosystems - with eDNA. eDNA, or environmental DNA, is free-floating genetic material that organisms leave behind in the water column, an almost invisible sign of their presence. Aboard NOAA Research Vessel Manta, eDNA was filtered and collected from seawater in the deep Gulf of Mexico, near Flower Garden Banks National Marine Sanctuary. With the use of eDNA as a more effective and less disruptive methodology, these scientists are unlocking the secrets of the deep ocean, and the incredible variety of animals that live there, one drop of seawater at a time.
