New research by the World Resources Institute (WRI) and the Virginia Institute of Marine Science, College of William and Mary, identifies more than 530 low-oxygen "dead zones" and an additional 228 sites worldwide exhibiting signs of marine "eutrophication." Eutrophication occurs when water bodies are over-fertilized by nutrients that are washed into surface waters from farms and urban areas.
