Pondering the pond: what Halema‘uma‘u water chemistry tells us

Detailed Description

Water collected from the lake at the bottom of Halema‘uma‘u is prepared for laboratory analyses at the USGS California Volcano Observatory. Results thus far reveal chemistry indicative of complex reactions between the water, magmatic gases, and Kīlauea's basaltic rocks. USGS photo by S. Peek, October 2019.
