Calculating important thermal metrics at Yellowstone National Park that can be used for monitoring change over time.

As part of ongoing grizzly bear and black bear research and management efforts and as required under the Endangered Species Act to monitor the population in the Greater Yellowstone Ecosystem, the U.S. Geological Survey, in conjunction with the National Park Service, is working to inform the public that scientific capture operations are once again about to begin within Yellowstone National Park.

Yellowstone’s hydrothermal system has been powered 24 hours a day, 365 days a year for at least the last ~2 million years by the release of heat from the magmatic system in the subsurface.

Tourism to Yellowstone National Park, which attracts millions of visitors a year searching for spectacular scenery, geothermal wonders, and a pristine environment, is responsible for generating nearly 2.3 billion pounds of carbon dioxide emissions each year, a new study says.
