Extreme Cave Diving
Learn the Science
INVESTIGATE UNDERWATER SCIENCE
The world under water holds many clues to the history and science of our planet—from a record of the Earth's climate to life forms that develop in extreme conditions, from evidence of how life first began to entire worlds lost beneath the water. Examine some of this research with your students.
Extreme Cave Diving (Video)
Understand how stalagmite formations found in blue holes record climate history and provide evidence of more than five major climate changes over the last 80,000 years. (Chapters 5 and 6, approx. 16 min.; Program available after broadcast)


Mystery of the Gakkel Ridge (Multimedia)
Explore the Arctic Ocean seabed and find out what it's telling scientists about life in environmental extremes.


Life in the Abyss (Article, Slideshow)
Read about the more than 300 species of life forms that exist in hydrothermal vents, harsh environments thousands of feet beneath the sea. Then, click the links to go "Inside a Tubeworm" and explore the creatures of a "Deep Sea Bestiary."


Deep Sea Vents and Life's Origins (Lesson/Video)
Understand how bacteria found deep in the ocean in the volcanic regions of mid-ocean ridges suggest a possible scenario for the beginning of life on Earth.
