Detailed Description

USGS scientists collect gas from the Puhimau thermal area on Chain of Craters Road in Hawai‘i Volcanoes National Park. The gas is collected in evacuated (vacuum-pumped so that no gas at all is inside) glass bottles, and a system of a syringe with tubing helped ensure minimal contamination by ambient atmospheric gases. Samples will be analyzed for bulk chemistry and helium isotopes, which can help identify the extent of deep magmatic degassing. USGS image by P. Nadeau.
