The Landsat program conceived of in the 1960s, has been running longer than any remote sensing program. The idea was simple: position a satellite in a nearly polar orbit fixed to the solar angle so that each daytime pass would cross the equator at roughly the same local time.

Mike Poland, scientist-in-charge of the Yellowstone Volcano Observatory, talks about Yellowstone’s recent earthquakes, trends in ground deformation, and Steamboat Geyser activity in this video update of May 1, 2022.

A Burning Question: What can long-term datasets tech us?

This video was recorded by a webcam on the northwest rim of Kīlauea caldera, and shows the active lava lake in Halema‘uma‘u. The lava flows from west to east (right to left in this image) and plunges down a cascade into a smaller pit, where the lava is highly agitated. USGS video by M. Patrick.

Welcome to the “I Am A..." series, a whiteboard animation video series highlighting USGS careers.

Fish Ecologist Mike Carey studies the impacts beavers have on warming Alaskan permafrost landscapes.

Research Wildlife Biologist Steve Matsuoka explores how climate change affects the reproductive success of Alaska’s diverse bird communities, which include more than 100 species that migrate to Alaska each year world to breed.

Research Fish Biologist Vanessa von Biela investigates how heatwaves and other climate-driven stressors may affect Alaska’s spawning Pacific salmon in the future.

Wildlife Biologist Vijay Patil explores the effects of climate change and shifting seasons on Arctic-nesting waterfowl.

Geologist Ann Gibbs studies the vulnerability of the rapidly-warming Alaska coast to climate change effects like sea level rise and permafrost thawing.

Along reef-lined shores of the Pacific Islands, USGS Research Geologist and Oceanographer Ferdinand Oberle studies how warming surface waters, nutrient runoff, and increasingly powerful storms impact coral reefs.  

Research Oceanographer Kira Mizell studies change in ocean chemistry by collecting marine minerals, looking for insights into past climate conditions and geologic history.

Yellowstone Volcano Observatory Scientist-in-Charge Mike Poland talks about a recent earthquake swarm in Yellowstone National Park, trends in ground deformation, and water eruptions at Steamboat Geyser, in this video update of recent activity (April 1, 2022).
