Space weather can have important consequences for our lives, such as interference with radio communication, GPS systems, electric power grids, the operation and orientation of satellites, oil and gas drilling, and even air travel as high altitude pilots and astronauts can be subjected to enhanced levels of radiation.

This webinar, "Application of High Resolution Climate Models to Benefit Avian Conservation in the Prairie Pothole Region, Northern Great Plains", was conducted by Susan Skagen and John Stamm as a part of the Climate Change Science and Management Webinar Series.

This video shows a series of clips collected in 2013 during the SAVSARP gravity experiment.

This webinar, ""Predicted Climate Change Effects on Fisheries Habitat and Production in the Great Lakes" was presented by David "Bo" Bunnell as a part of the USGS National Climate Change and Wildlife Science Center's Climate Change Science and Management Webinar Series.

This webinar, "Historical Trends in Summer Precipitation, Baseflows, and Stormflows in New England and Projections of Seasonal Streamflows for Coastal Streams in Maine", was conducted by Rob Dudley and Glenn Hodgkins as a part of the USGS National Climate Change and Wildlife Science Center's Climate Change Science and Management Webinar Series.

This thermal image sequence shows the typical motion of the lava lake in Halema‘uma‘u Crater. For scale, the lake is about 160 meters (520 feet) wide in this view. The clip spans about 12 minutes, and is shown at 30x speed. The lava upwells along the north margin of the lava lake (in this view, near the top of the image).

There were two documented gray fox visits at the burrows, making them the third most documented predator. Gray foxes are implicated predators of various life stages of desert tortoises, but it is difficult to catch them in the act. In this case, a gray fox approaches a burrow, and thoroughly investigates the burrow mouth.

There was one documented skunk event captured on camera - the least documented predator. Here, a western spotted skunk is thoroughly investigating the burrow of one of the marked female tortoises in the study population. Western spotted skunks are known predators of turtle eggs.

In this video we briefly discuss the removal of the Great Works Dam on the Penobscot River in Maine. We also highlight some work the USGS is doing to document river conditions before and after dam removal.

Substrate is mainly a gravel sand mixture.

In 1986, Congress directed the USGS to regularly report groundwater-level changes in the High Plains aquifer system. To comply with this directive, the USGS compares water levels measured every two years. By measuring water levels across the entire aquifer in one year, measurements made two years later enable calculation of changes over time.

Permanent Site: A2 West Transect; Depth: 12.9 Meters (Feet 42.3); Distance from river mouth: Kilometers 1.8 (1.1 Miles); Pre/Post Dam Removal: 2 years post-dam removal; Lat/Long: 48.14130295, -123.5883331; Site Description: One of our deeper sites at over 40 feet. Sediment is primarily sand/sandy mud with scattered boulders.
