North Platte River ADCP Measurement
Recent warm weather has increased flow in the North Platte River to above average for the date at the streamgage at Northgate, CO (just upstream of the WY-CO stateline). Real-time data online at: http://ow.ly/vodL50zt6YO

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.

Hydrothermal isotopes from Yellowstone and Iceland
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).

Mauna Loa summit mission-critical fieldwork: MultiGAS installation
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.

First Open Water Measurement of the Year
With ice off the Wind River near Kinnear, we headed out to make a streamflow measurement in open water. Flows were a bit higher than average for the date (35 years of record) and can be found real-time at: http://ow.ly/eSXS50zcGLF

Scientists with the Interagency Grizzly Bear Study Team have seen the first female grizzly bear with cubs of the year for 2020 in Yellowstone National Park. The radio-collared female was seen with 3 cubs during a telemetry tracking flight on 4/10. One of the 3 cubs is hard to see between the 2 obvious siblings, but you can just make out its
