A VAST FLOATING ISLAND OF TRASH. Estimates on size range from 270,000 sq mi
to more than 5,800,000 sq mi or "twice the size of the
continental United States". The area may contain over 100 million tons of debris. THERE ARE ALSO NUMEROUS SMALLER GARBAGE PATCHES IN THE OTHER OCEANS AND SEAS.
20,000 Gallons of Exxon Valdez Oil Still Trapped in Alaskan Beaches It's been over 20 years since the Exxon Valdez
ran into a reef and spilled nearly 11 million gallons of crude oil into
Prince William Sound, but according to new research published in Nature Geoscience about 20,000 gallons remain trapped in the gravel beaches of Alaska.
Initially oil was estimated to be dispersing at a rate of about 70% per
year, but this newer research shows that rate to be just 4%. Because of
that high initial estimate beach remediation was stopped in 1992.
