The U.S. Geological Survey (USGS) is both a user and a provider of remotely sensed data. The USGS operates and manages the Landsat satellite series and a Web-enabled archive of global Landsat imagery dating back to 1972. Landsat represents the world’s longest continuously acquired collection of space-borne moderate-resolution land remote sensing data and the entire archive became available for download at no charge in December 2008.  The USGS also distributes aerial photography through The National Map, and archives and distributes historical aerial photography, light detection and ranging (lidar) data, declassified imagery, hyperspectral imagery, data collected by Uncrewed Aircraft Systems (UAS), and imagery from a variety of government, foreign, and commercial satellites. These data are used for a wide variety of applications such as mineral resource development, monitoring the health of U.S. and global ecosystems, land use change, emergency response, and assessments of natural hazards such as fires, hurricanes, earthquakes, droughts, and floods.

Walruses Are Visible in Satellite Imagery When They Rest on Shore in Large Numbers

Submitted by atripp on Tue, 12/27/2022 - 09:42

During late summer and autumn, Pacific walruses are resting on shore north of the Bering Strait more often and in larger numbers in both the United States and Russia.  Historically, walruses rested primarily on floating sea ice over their offshore foraging grounds in this region, but climate warming has reduced availability of sea ice.  With greater numbers of walruses gathering on shore, USGS scientists and collabor

Testing a Small, Portable Remote Passive Acoustic Device to Monitor Wolves

Submitted by atripp on Tue, 12/27/2022 - 09:32

As part of a broader trial of noninvasive methods to research wild wolves (Canis lupus) in the Superior National Forest (SNF), Minnesota, the USGS Wolf and Deer Project (Northern Prairie Wildlife Research Center) explored whether wolves could be remotely monitored using a new, inexpensive (approximately $80 USD in 2019), remotely deployable, passive acoustic recording device.

High-resolution Mapping of Energy Infrastructure and Impacts on Mule Deer Movement

Submitted by atripp on Tue, 12/27/2022 - 09:13

Mule deer are known to avoid human disturbances, including energy infrastructure and development. By combining remote sensing data, GIS modeling, and information on energy expenditure of mule deer, researchers developed a spatiotemporal model to map the minimum energy expenditure required for mule deer to traverse a landscape with increasing levels of oil and gas development on the northern Colorado Plateau.

Central Valley Waterfowl Dynamic Habitat Mapping

Submitted by atripp on Fri, 12/23/2022 - 13:55

Waterfowl populations within California's Central Valley are unusual among most North American waterfowl populations in that the region contains both resident and migratory populations of several species.  The region supports 60% of the waterfowl and waterbirds that stopover for at least part of the year along the Pacific Flyway, a major north-south migratory pathway.
