The visible impact of climate change on the Earth’s surface is often clearest in the Arctic’s receding glaciers and swelling glacial lakes. Southeastern Alaska’s Harlequin Lake is one of the fastest-growing in North America. These false color Landsat images show the rapidly-retreating Yakutat Glacier, which feeds the lake.

Our Nation’s economic security and environmental vitality rely on continuous monitoring of the Earth’s continents, islands, and coastal regions in order to record, study, and understand land change at local, regional, and global scales. The USGS National Land Imaging (NLI) Program helps meet this need. This image is a portion of the first Landsat 8 scene acquired May 12, 2013, in Western Australia. The resulting image displays impressive sediment and nutrient patterns in the tropical estuary area, and the complex patterns and conditions in the vegetated areas.

At the USGS EROS Center, we study land change and produce land change data products used by researchers, resource managers, and policy makers across the nation and around the world. We also operate the Landsat satellite program with NASA and maintain the largest civilian collection of images of the Earth’s land surface in existence, including tens of millions of satellite images.

Changes in the environment, land use, and climate can have significant impacts on our Nation’s economy, natural resources, infrastructure, and water, food, and energy security. To strengthen our Nation’s ability to respond and adapt to these stressors, the USGS Land Change Science Program conducts research to improve understanding of rates, causes, and consequences of climate and land-use change.

The Energy Policy Act of 2005 established the National Geological and Geophysical Data Preservation Program (NGGDPP) to preserve and expose the Nation’s geoscience collections (samples, logs, maps, data) to promote their discovery and use for research and resource development. The National Digital Catalog describes geoscience collections managed by USGS and state geological agencies.

New Maps Document Big-Game Migrations Across the Western United States
For the first time, state and federal wildlife biologists have come together to map the migrations of ungulates – hooved mammals such as mule deer, elk, pronghorn, moose, and bison – across America’s West. The maps will help land managers and conservationists pinpoint actions necessary to keep migration routes open and functional to sustain healthy big-game populations.

Image of the Week - Fires Tear Through Former Cane Fields
The waves of sugar cane that once defined the Hawaiian island landscape of Maui, have slowly given way to non-native annual grasses in recent decades. Those grasses have become a fire hazard along the way.

Image of the Week - Iowa Fields Flattened
The punishing derecho storm that struck the Midwest in early August had an immediate impact on Iowa's farm fields. But it took weeks for the long term damage to appear in satellite imagery. Landsat 8 passed over central Iowa just one day after 100 mile per hour winds pummeled fields of corn and soybeans leaving thousands without power.

Image of the Week - Summer Fires Rage in California
As fire season continues in the western United States let's look back at a number of incidents tracked by officials across California in August. These fires were captured during the day by Landsats 7 and 8, in natural color bands of the visible spectrum. Landsat sensors also record infrared wavelengths revealing burn scars and active fires.
