our planet’sdead zones.
Black dots show where dead zones have been observed, but their size is unknown. It’s no coincidence that dead zones occur downriver of places where

Data from Robert Diaz, Virginia Institute of Marine Science (dead zones); the GSFC Ocean Color team (particulate organic carbon); and the Socioeconomic Data and Applications Center (SEDAC) (population density).
