Underwater forest: Ancient cypress forest buried off Alabama's coast, The Bald Cypress forest was buried under ocean sediments, protected in an oxygen-free environment for more than 50,000 years, but was likely uncovered by Hurricane Katrina in 2005, said Ben Raines, one of the first divers to explore the underwater forest and the executive director of the nonprofit Weeks Bay Foundation, which researches estuaries.The forest contains trees so well-preserved that when they are cut, they still smell like fresh cypress sap, Raines said.
The stumps of the Cypress trees span an area of at least 0.5 square miles (0.8 kilometers), several miles from the coast of Mobile, Ala., and sit about 60 feet (18 meters) below the surface of the Gulf of Mexico.
Despite its discovery only recently, the underwater landscape has just a few years to be explored, before wood-burrowing marine animals destroy the ancient forest.
Closely guarded secret
Raines was talking with a friend who owned a dive shop about a year after Hurricane Katrina. The dive shop owner confided that a local fisherman had found a site teeming with fish and wildlife and suspected that something big was hidden below. The diver went down to explore and found a forest of trees, then told Raines about his stunning find.
But because scuba divers often take artifacts from shipwrecks and other sites, the dive shop owner refused to disclose the location for many years, Raines said.
In 2012, the owner finally revealed the site's location after swearing Raines to secrecy. Raines then did his own dive and discovered a primeval cypress swamp in pristine condition. The forest had become an artificial reef, attracting fish, crustaceans, sea anemones and other underwater life burrowing between the roots of dislodged stumps.
Some of the trees were truly massive, and many logs had fallen over before being covered by ocean sediment. Raines swam the length of the logs.
"Swimming around amidst these stumps and logs, you just feel like you're in this fairy world," Raines told LiveScience's OurAmazingPlanet.
Primeval forest
Raines reached out to several scientists to learn more about the forest. One of those scientists was Grant Harley, a dendrochronologist (someone who studies tree rings) at the University of Southern Mississippi.
Harley was intrigued, and together with geographer Kristine DeLong of Louisiana State University, set out to discover the site's secrets.
