The devastation of southern Gulf Coast forests by Hurricane Katrina was documented in before-and-after images from the Landsat 5 satellite.
Nov 15, 2007Landsat Helps Show That Forests Damaged by Hurricane Katrina Become Major Carbon Source

With the help of Landsat and MODIS data, a research team has estimated that Hurricane Katrina killed or severely damaged 320 million large trees in Gulf Coast forests, which weakened the role the forests play in storing carbon from the [...]
