"Extreme Cave Diving" premieres Tuesday, February 9 at 8PM ET/PT on PBS (please check local listings). Watch the TV commercial within.
"Extreme Cave Diving" follows a fearless team of scientists as they
venture into blue holes—underwater caves that formed during the last
ice age, when sea level was nearly 400 feet below what it is today.
These caves, little-known treasures of The Bahamas, are one of Earth's
least explored and perhaps most dangerous frontiers. The
interdisciplinary team of biologists, climatologists, and
anthropologists, led by renowned cave explorer Kenny Broad, discover
intriguing evidence of the earliest human inhabitants of the islands,
find animals seen nowhere else on Earth, and recover a remarkable
record of the planet's climate.
The stakes are high as the scientists
swim hundreds of feet through narrow, dark passages that have trapped
and killed divers in the past, but the scientific payoff is considerable.
