From Source to the Photosynthetic Fringe : The Downstream Geochemistry of Yellowstone National Park's Hydrothermal System
Hydrothermal features provide a unique and extreme environment that can act as a proxy for studying both past earth environments and similar environments of interest that exist throughout the universe today. Yellowstone National Park contains more than half of the world's hydrothermal springs; over 10,000 features in all. As waters flow out of hydrothermal features they cool, evaporate, and interact with the air. This results in significant changes in water chemistry as the outflowing waters move away from their source. Outflow samples were collected that represented Yellowstone's entire geochemical ...
