When wetland plants in the northeast emerged this spring, USGS scientists were working from home and unable to start many planned research activities. However, many instruments were already deployed and continued to collect information critical to USGS research.

The relationship between Δ30 and N2/3He ratios in hydrothermal gases from Iceland and Yellowstone. Δ30 and N2/3He ratios are shown for samples collected from gases in Iceland (yellow circles) and Yellowstone (red circles). The Yellowstone mantle-endmember is arguably indistinguishable in terms of N2/3He from the convecting upper mantle (grey diamonds).

On April 27, HVO field engineers and a gas geochemist conducted fieldwork to increase HVO's volcano-monitoring capabilities. Staff installed a MultiGAS station to collect volcanic gas data from within Moku‘āweoweo, Mauna Loa's summit caldera. The work was carried out with permission of Hawai‘i Volcanoes National Park.

USGS scientists visit Garden Wall Weather Station in Glacier National Park.  This high elevation weather station, just below the Continental Divide near Logan Pass, collects weather data that is used each spring to forecast avalanche hazard for the road crew plowing Going to the Sun Road.  The data is also used by USGS avalanche scientists to study the con
