--->Formation of underwater "plumes" of oil and water mixed.
--->Markedly increased methane concentrations (up to 10,000 times normal so far) in large underwater "plumes" which could eventually create extensive "dead-zones."
--->Decreased oxygen levels in underwater oil plumes.
--->Decreased phytoplankton "bloom."
--->Extensive Destruction of Gulf wet-lands, aquatic fish, mammals and bird life.
