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.

Do Droughts Affect Groundwater Quality? A California Story

By Zeno Levy, USGS Research Geologist

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.

This video, taken on February 10, 2022, shows lava upwelling at the western vent, in Halema‘uma‘u crater at the summit of Kīlauea, before flowing into the lava lake to the east via a narrow channel.

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.

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.

This monthly update from the Yellowstone Volcano Observatory begins with a story.

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.

On January 28, the USGS-Hawaiian Volcano Observatory conducted Unoccupied Aerial Systems (UAS) missions at the summit of Kīlauea, within Hawai‘i Volcanoes National Park.

HVO field crews participated in an overflight and ground work at the summit of Kīlauea on January 27. This video compilation contains footage taken from the air and ground.

Species Here, Species There, Species, Species Everywhere - Why do Species live where they do?

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.

2021 was an interesting year for deformation at both Kīlauea and Mauna Loa volcanoes. At Kīlauea, 2021 provided a glimpse of what the future might hold as the system recovers from the large collapses that accompanied the 2018 lower East Rift Zone eruption.
