Did You Know…What’s That Glow?

Maryland Sea Grant and the University of Maryland Center for Environmental Science are working with researchers in Puerto Rico to determine what is causing the coastal lagoons to glow.

It’s a fascinating project, and the devastation of Hurricane Maria has made the work all the more challenging.
