• Glacier Numerology – The how big, how long, how thick, how much, how often, of glacier science.
• Glacier Photography – While a picture may be worth a thousand words, a collection of images may tell a complete forensic story.

Warm summers and short winters are thawing permafrost in the Siberian tundra, causing soil erosion. As a result, the 800 meter wide Batagaika crater continues to expand.



At the USGS EROS Center, we study land change, operate the Landsat satellites, and maintain the longest, continuously acquired collection of images of the Earth's land surface.

This webinar was conducted on July 17, 2017 as part of the USGS National Climate Change and Wildlife Science Center Climate Change Science and Management Webinar Series, held in partnership with FWS National Conservation Training Center. 

The USGS and its cooperators have installed debris-flow monitoring equipment in the largest drainage basin at Chalk Cliffs, CO. Data collection at this site supports research on the hydrologic factors that control debris-flow initiation, entrainment, and flow dynamics.

Softball-sized hail caused millions of dollars of damage to the USGS EROS Center 20 years ago this week. July 13, 1997, marks the date of the massive hailstorm in southeastern South Dakota. 

Mountain lions, desert bighorn sheep, mule deer, and a variety of other wildlife live on and pass through the Nevada National Security Site each day. It’s a highly restricted area that is free of hunting and has surprisingly pristine areas.This 22-minute program highlights an extraordinary study on how mountain lions interact with their prey.

Yellowstone grizzly bears inhabit federal, state, tribal, and private lands, and long-term research requires careful coordination across governmental levels.

More than 7 million Landsat satellite images now available.

Landsat Collections: Providing a Stable Environment Record for Time Series Analysis

A USGS Instagram Story (@USGS on Instagram) about kids at Science Camp 2017 learning about topographic maps and why they're important. 

Title: The Effects of Climate Change: A Scientific Pathway Forward

• The frequency of extreme and unpredictable weather events is increasing.
• What are the effects of an increase or decrease in carbon emissions?
• What is scientific research projecting for the future of climate change?

Landsat helps scientists monitor land change on Mt. Pinatubo, 26 years after the eruption.

Landsat helps document large-scale deforestation in Peru.

The widespread land change is captured over the past few decades.

A tutorial by USGS scientist and topoView developer Chris Garrity demonstrating how to use topoView version 2.1. TopoView let's you access and download maps free of charge from the USGS's Historical Topographic Map Collection, published between 1884 and 2006.

Flyover of the southeast Ceti Mensa map. Distinct groups of rock layers, called geologic units, are shaded in different colors, with dark browns representing the oldest rocks and green representing the youngest rocks. All of these rocks formed as wind-blown sand that became trapped in shallow, ephemeral lakes, similar to the wet playas of the desert southwest US.

The Arizona Water Science Center demonstrates new methods in Reach-Scale Monitoring to improve accuracy and measurability of high flow events. By installing pressure transducers and using LiDAR to measure topography data, hydrologists are able to simulate flows with two dimensional models which will help better calibrate stream gages.

Landsat 8 collects it's 1 millionth scene. See it for yourself!
