Tree rings record spikes in magmatic CO2 emissions at Yellowstone
Volcanologists have a variety of ways of measuring present-day gas emissions from volcanoes. But what about gas emissions that happened in years past, before measurements were possible? For these periods, it turns out that you can actually read the signature of gas emissions in tree rings!

Helium isotopes carry messages from the mantle
Scientists who work at Yellowstone are interested in finding physical and chemical signals from the deep magmatic system, both to better understand the nature of the system and also to monitor for possible changes. Helium is an inert gas that is an excellent tracer of magmatic processes.
