A Walk Through the Hydroclimate Network in Yosemite National Park: River Chemistry

This is the chemistry component of the hydroclimate network described in Jessica Lundquist's Nature Notes article “Monitoring snow from the beach in San Diego: Automatic snow sensors in the Sierra”. Efforts to link large-scale atmospheric circulation to snowpack and snowmelt–driven river discharge and riverine chemistry will ultimately contribute to the accuracy of climate change models and their ability to predict downstream effects on human use.

Airborne Pollutants in National Parks: Sequoia Park joins Large Study Effort

From sources as far away as Europe and Asia, some of the world’s most toxic persistent chemicals are carried on air masses and are being deposited in high elevation and high latitude ecosystems in the Western United States and Alaska, including Sequoia National Park.

Fire Regimes in Sierran Mixed-Conifer Forests

Fire is a vital part of the Sierra forest ecosystem. Tree-ring analyses allows scientists to date the frequency and intensity of natural fires to better understand the role between climate cycles and fire frequency.

High Sierra Water: What is in the H20?

After decades of too often shrill warnings about Sierra water, Dr. Derlet continues to lower the panic level considerably with actual research. Although filters are probably not a bad idea, our Sierra streams and lakes are much, much better than we seem to think.
