Map of anoxic events

Summary

[edit]
Description
English: Red circles on this map show the location and size of many of our planet’s dead 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 human population density is high (darkest brown). Darker blues in this image show higher concentrations of particulate organic matter, an indication of the overly fertile waters that can culminate in dead zones.
