Title: Bats in the West: Discoveries, Questions, and Future Research
By Gabriel A. Reyes, USGS Biologist

• Learn about bat ecology, diversity, and the role they play in our ecosystem.
• See how scientists are using a variety of methods including capture, acoustic monitoring, and tracking, to learn more about local bat species.
• Find out how

Tidal marshes exist as a transitional environment between the land and sea, and provides habitat to fish and wildlife, protects human developments from coastal flooding, and stores carbon at high density, among other important ecosystem services. Over the next century, accelerating sea-level rise poses a risk to tidal marshes, especially in areas with insufficient sediment

This timelapse video covers about 30 minutes of activity at the water pond in Halema‘uma‘u at the summit of Kīlauea. Water appears to be flowing into the pond from several locations, including the southern boundary (right side in this image). A small amount of material is also seen floating on the surface at the eastern end of the pond (top of image). The video is shown

This time-lapse video shows circulation in the water pond in Halema‘uma‘u over a period of about 25 minutes. There appears to be an influx of water along the southern (right) shoreline. A broader eastward flow of water (toward top of image) is evident. The video is shown twice. USGS video.

Views of the water pond in Halema‘uma‘u on Friday, September 6, and Monday, September 9 are shown in this video. Ripples are evident on the pond, presumably due to wind moving over the water surface. No significant changes in the pond were observed over the weekend, and the water level continues to slowly rise. USGS video by M. Patrick.

Shown at 30x speed, this video highlights changing activity on the surface of the water pond. Steam wafting above the pond shifts in the wind, and circulation of the water is evident in areas of sharp color boundaries. USGS video by M. Patrick, 09-17-2019.

Abnormally high spring rainfall and subsequent flooding in the Midwest had a season-long impact on cropland production. In these Landsat images of South Dakota growing vegetation is shown as green and unplanted areas appear pink. The difference between 2018 and 2019 is striking.

A designation of "prevented planting" is given to unplanted acres as a signal to crop

This video was taken during the SW1321 training course, Streamflow Measurements Using ADCPs. On this field day, students from all over the USGS used their newfound knowledge to collect ADCP data in Windham, Maine.
 

In July, satellite imagery from Landsat 8 captured a major melting event in Greenland.

Setting sail from Woods Hole, MA to Cape Cod Bay aboard the R/V Warren Jr. USGS scientific staff will define the geologic framework of Cape Cod Bay to aid the state of Massachusetts in management and assessment of resources and hazards.
 

In 2019, the USGS Youth & Education in Science (YES) team marked the 150th anniversary of the first John Wesley Powell expedition down ~1000 miles of the Green & Colorado rivers with a national-scale educational project known as "Powell150." Educational resources about the science along the rivers and a social media campaign around the theme of exploration were

This sequence captured on August 31 begins with a close-up of the fumaroles on the north side of Halema‘uma‘u, then shows a broader view of the crater with the water pond at the bottom and a close-up of steaming and ripples on the water surface. USGS video by M. Patrick, 08-31-2019.

Another day of clear weather provided good views of the water pond in Halema‘uma‘u at Kīlauea's summit. No significant changes were observed, and the thermal camera showed the water surface is still about 70 degrees Celsius (158 degrees Fahrenheit). USGS video by M. Patrick.

Title: Pliocene World: Earth's Climate 3 Million Years Ago and How it Relates to our Future
By Marci Robinson, USGS Research Geologist 

• Three million years ago, during the late Pliocene, CO2 levels were similar to today, but global temperatures and sea level were much higher
• Find out how we use microfossils to reconstruct

Daytime and nightime imagery from Earth-observing satellites reveal dramatic changes in North Dakota during the Bakken oil boom.
 

During Aug. 4-8, 2019, U.S. Geological Survey women scientists, university researchers and Mount St. Helens Institute staff led 25 middle-school girls from Washington and Oregon in the fifth annual “GeoGirls” outdoor volcano science program at Mount St. Helens, Washington.
 

Pu‘u ‘Ō‘ō remains quiet. Clear weather during HVO's August 22 overflight provided good views into the drained crater. Rubble from crater wall collapses has filled in much of the deeper part of the crater, with the bottom now at about 250 meters (820 feet) below the east rim. The curvature of the horizon is caused by the wide-angle view of the camera. USGS video by M.

This video presents an animation of computer-simulated ground motions that might occur for a magnitude 6.9 earthquake rupturing the Rose Canyon fault in southern California. The scenario earthquake ruptures a 65-km-long section of the Rose Canyon fault that lies just offshore of San Diego, California, and Tijuana, Mexico. In this scenario, the rupture starts near the

Clear weather afforded good views of the water pond in Halema‘uma‘u. No major changes were observed in the pond, but the water continues to slowly rise. The water surface was steaming, and its temperature was approximately 70 degrees Celsius (158 degrees Fahrenheit). For scale, the pond is about 70 meters (230 feet) long. USGS video by M. Patrick.
