Summary
Description Aquatic Dead Zones.jpg |
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.
