In late July the Chesapeake Bay saw one of the worst “dead zones” on record, an area with low-oxygen water. By early August, conditions returned to the typical range, but efforts are ongoing in Maryland and surrounding states to shrink the dead zone. We speak to Tim Wheeler, managing editor of The Bay Journal, and Dr. Don Boesch, president of the University of Maryland Center for Environmental Science. What do low oxygen levels mean for the health of plants and animals in the Bay? How will climate change - expected to bring warmer water temperatures and rising sea levels - affect the “dead zone”? We take a deep dive into the dead zone.
