Happy 150th birthday to Yellowstone National Park! The Park is truly a wonderland, and a place of continuous inspiration and learning. Listen, as Yellowstone Volcano Observatory Scientist-in-Charge Mike Poland recounts some of its unique history and provides an update of recent earthquakes, ground deformation, and geyser activity.

Scientists continue to study how a warming Arctic will affect polar bear populations. The new 2022 Polar Bear Research Council Masterplan identifies how polar bears in zoos can help fill knowledge gaps that benefit wild populations.

The sturdy root systems of mangrove forests act as buffer zones along the coastlines of some of the planet’s most vulnerable communities, protecting lives, ecosystems and property from the rigors of hurricanes and tsunamis.

This video clip shows typical activity at the west vent, in Halema‘uma‘u crater at the summit of Kīlauea. Lava upwells in a small pond and then flows into the main lake via a narrow channel.

A satellite image of the mountains that will host Olympic skiing events should display a snowy landscape, right? But the National Alpine Ski Centre and Sliding Centre 45 miles northwest of Beijing, China doesn't get much snowfall. Instead, the steep slopes are lined with manmade snow.

Eruptive activity at the summit of Kīlauea, within Halema‘uma‘u crater, has recently been characterized by the eruption waxing and waning over timescales of days. This video, captured from February 7–10, 2022, by the F1cam, a thermal camera located on the west rim of the caldera and looking east, shows the eruption pass through a pause cycle.

Narrated presentation that provides a unique, long-term perspective (1950-2050) of the major drivers of nitrogen change up to the present, and forecasts how they may affect nitrogen into the future for the Chesapeake Bay watershed. Information is based off of U.S. Geological Survey Circular 1486.

If you want to know how much rain fell yesterday, you can catch it and measure it. Water vapor? That's not so easy. Which is a problem if you want to know how quickly that rate is returning to the atmosphere. Water vapor is the single largest part of the water budget, but without space-based observations, it would be all but impossible to measure at wide scale.

Landsat 7 had the honor of acquiring the satellite program’s 10 millionth scene in November 2021.
The scene captures changes to the Dead Sea, located in Southwest Asia. The Dead Sea is mainly fed by the Jordan River, which enters from the north. However, the water level of the Dead Sea has been falling due to irrigation projects and water use upstream.

The Arctic region is warming faster than anywhere else in the nation. Understanding the rates and causes of coastal change in Alaska is needed to identify and mitigate hazards that might affect people and animals that call Alaska home.

A Kīlauea summit eruption monitoring shift on February 4, 2022, provided views of the eruption within Halema‘ma‘u crater. Lava flows from a pond north of the west vent into the lava lake, which exhibits areas of spattering.

These video clips show recent activity at the lava lake in Halema‘uma‘u crater, at the summit of Kīlauea. Lava upwelling at the western vent flows into the lake, where bubbling is commonly present. In the eastern portion of the crater, a steep spatter cone has produced vigorous spattering and small lava flows.

USGS geologist Dan Dzurisin is near Sisters, in Central Oregon, to set up portable GPS monitoring equipment to track something that's been going on for 25 years and still goes on today. It’s uplift, a subtle rise in the ground’s surface, in an area west of South Sister volcano.

In the winter of 2015, the public noticed thousands of dead seabirds washing ashore across the western coast of the United States and Canada. The USGS linked this massive seabird die-off to the North Pacific Marine Heatwave. A marine heatwave occurs when sea surface temperatures are above normal for an extended period of time.

The rangelands of the western United States are changing more quickly than many other parts of the lower 48. Miles upon miles of the area or semi-arid landscapes in states like Idaho, Montana and Nevada are now carpeted by fire fueling invasive grasses. Cheatgrass is the most prevalent, which is troublesome for several reasons.
