The Massive Amount Of Crap Left By Irene In New York's Harbour

NASA has released this true-colour satellite image of New York Harbour. It usually is full of crap, but this photo shows a lot more. All that vomiting green and brown you see? It's the effect of Hurricane Irene.

According to David Ralston, of the Woods Hole Oceanographic Institution:

The sediment flux from Irene is really massive...unusual, but not unheard of. One big event like this can move and deposit as much sediment as you might get in several years of regular flow on the Hudson

According to NASA, the different colours depend on the "amount and type of sediment, as the green, tan, and deep brown areas have varying degrees of suspended silt, sand, mud, leaf tannins, and other organic matter." Scientists from the US Geological Survey and other research centres are now analysing this matter, trying to find out the exact amount of sewage, pesticides, and excess fertiliser that the hurricane put into the water.
