Landsat satellites offer a wealth of information to scientists studying ecosystem health and recovery. Data products derived from Landsat open even more areas of inquiry. Landsat Burned Area products, for example, can help researchers identify previously unknown fires that took place from 1984 through the present.

Image of the Week — Industrial Evolution in New York
Image of the Week — Industrial Evolution in New YorkThe Staten Island Industrial Park in New York is now home to warehouse and distribution centers for companies like Amazon and IKEA, seen here in imagery from Europe's Copernicus Sentinel-2 satellite. But aerial imagery from 1995 shows large oil storage tanks in the same location.

The relationship between Δ30 and N2/3He ratios in hydrothermal gases fromThe 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).

Eyes on Earth Episode 22 – Meet the Mendenhall Fellow
Eyes on Earth Episode 22 – Meet the Mendenhall FellowThe Mendenhall Program offers a range of two-year post-doctoral research fellowships within the U.S. Geological Survey. Heather Tollerud took advantage of the program in 2015 to study drought and land cover at the USGS EROS Center, and has since become a key player in the Center’s innovative Land Change Monitoring, Assessment and Projection (LCMAP) initiative.

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

USGS Responds to Spring Flooding in Minnesota
On April 10, USGS hydrographer Josh Sundberg measures Red River water flowing over the road in East Grand Forks, Minnesota as flood protection walls prevent further flooding.

A geologists makes observations at Kilauea
Clear weather allowed HVO geologists to make observations and take measurements of the water pond at Kīlauea's summit. No major changes were observed, and the water level continues to slowly rise. Note the former HVO observation tower can be seen above the geologist's helmet.

Changes in color at Kīlauea's summit water pond are commonThis compilation shows the appearance of the water pond at Kīlauea's summit over the past two weeks. Day to day changes in the color of the pond are common, with portions of the pond shifting from a green hue to brown. A sharp color boundary has been common for several months in the same general area of the pond.

Eyes on Earth Episode 21 - Forests of Ghana
In the West African nation of Ghana, tropical forests are more than landscape. They are woven into language, custom, and culture. They are also the source of timber for home heating and industry, as well as barriers to agricultural production. Those are just a few of the reasons why deforestation has come alongside the nation’s rapid population growth.
