The cover story of the most recent issue of National Geographic Magazine (August 2010) features a University of Miami (UM) led expedition to the underwater caves of the Bahamas, known as ‘blue holes.’ These unique environments are one of the least understood ecosystems on the planet, largely due to the challenges involved in studying these extreme environments, which include complete darkness, dramatic reversing currents, extreme depths, poisonous gasses, and silty, tight squeezes. The expedition made significant findings related to the past history of the earth, including human occupation, previously undiscovered microbial life, and abrupt climatic changes. The expedition was conceived of and led by National Geographic Emerging Explorer Kenny Broad, Director of UM’s Leonard and Jayne Abess Center for Ecosystem Science and Policy, and Associate Professor at UM’s Rosenstiel School of Marine and Atmospheric Science. Funded by The National Geographic Society, the National Museum of the Bahamas, and the National Science Foundation, this work included more than 150 dives and involved unique collaboration between cave divers, scientists from several different fields, and a specialized film team led by the late Wes Skiles, a renowned filmmaker, conservationist and cave explorer. The expedition also was featured in a one-hour NOVA PBS special entitled “Extreme Cave Diving.”
