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.

Subject(s): Geology/Earth Science, Life Science/Biology The remotely operated vehicle (ROV) Jason II measured temperatures as high as 200 degrees Celsius (392 degrees Fahrenheit) at these hydrothermal vents atop the Forecast Seamount in the Mariana Arc of the Pacific Ocean. Hydrothermal vents spew sulfur and other chemicals that support bacteria which use these chemicals to sustain life in a process called chemosynthesis. Snails and shrimp have colonized the site and are grazing on the chemosynthetic bacteria. Jason's suction sampler is used to collect some of these animals for analysis in the lab on board the ship.

Subject(s): Life Science/Biology, Geology/Earth Science McMurdo Station is the American staging area for Antarctic research. At the edge of Ross Island, off the coast of the continent, a small town of workeres feeds, houses, prepared, supplies, fuels, transports, and protects those who conduct field research throughout Antarctica and the surrounding waters. The community numbers 1,000 in the summer and 200 in the winter.
And the community has a garden, from which they obtain their only fresh produce. Many love to visit this polar paradise.
