Underwater forest near Alabama may provide clues about ice-age ecology

Ten miles off the coast of Alabama, an underground cypress forest is being studied by scientists to help learn about the climate of 50,000 years ago, when the forest was alive, according to a recent story by National Public Radio.  The ice-age forest may be able to provide new clues about how forests grew in a colder climate and how ecosystems then were different than now. The forest was buried by mud until a hurricane in 2004 swept away the muddy covering, exposing the forest to divers. You can read more about it here.
