Yellowstone serves as an outdoor laboratory, offering invaluable insights across numerous scientific fields such as geology, hydrology, biology, ecology, and archaeology. But conducting research there is no small feat, especially in areas frequently traversed by bison, which can unwittingly become formidable obstacles to scientific efforts.
Thirty years ago, trees began to die on the sides of a volcano in California's Sierra Nevada range, choked at their roots by carbon dioxide seeping out from the mountain's bowels following a series of minor earthquakes.
A Stanford University study suggests the weight of snow and ice atop the Sierra Nevada affects a California volcano’s carbon dioxide emissions, one of the main signs of volcanic unrest.
Thirty years ago, on the flanks of a volcano in California's Sierra Nevada range, trees began to die en masse, suffocated at their roots by carbon dioxide seeping up from the mountain's depths after a swarm of small earthquakes.
