Tracking Ocean Trash by Satellite

DoubleWhopper writes "From the "Intersting Use of Technology" file comes this article on NOAA's tracking of oceanic debris with satellites used for tracking fish. From the article, "...during three days of study, about 2,000 individual pieces of debris were seen", and, "A number were balls of net up to 30 feet across." The researchers verified the information with the aid of a NOAA aircraft and digital imaging."
