Searching for diesel at the Kamchatka Microbial Observatory. The Geyser Valley is a "candy shop" for microbiologists and geochemists. Bears lumber across a pristine landscape in remote Kamchatka, Russia. Discovered just 60 years ago, this remote valley in Russia is a treasure trove for scientists studying microorganisms that survive under extreme conditions. Tour the lab tent where scientists study the unique microbiology and geochemistry of the hot springs of Russia's Uzon Caldera. Hot mud, boiling up in remote Russia. The sun goes down in a cloudy sky in Kamchatka, Russia. Two Russian scientists--geologist Gennady Karpov and microbiologist Elizaveta Bonch-Osmolovskaya--discuss the unique volcanic features of the Uzon Caldera, the life forms living in the hot springs there, and the important questions they raise. This clip introduces the 2006 expedition to remote Kamchatka, Russia. Twenty scientists arrive via helicopter to study the unique microbiology and geochemistry of the hot springs of the Uzon Caldera. Microorganisms that can survive the scalding temperatures and acidity in the springs are called extremophiles, and understanding these organisms helps answer questions about the origin and evolution of life on earth.
