Extreme Cave Diving

Series Website »
Episode Guide »
Follow the charismatic Dr. Kenny Broad as he dives into Blue Holes -- underwater caves that formed during the last ice age when sea level was nearly 400 feet below what it is today. They are Earth's least explored and perhaps most dangerous frontiers. With an interdisciplinary team of climatologists, paleontologists and anthropologists, Broad investigates the hidden history of Earth's climate as revealed by finds in this spectacularly beautiful "alternate universe."
