This video shows a close-up of the ponded water at the bottom of Halema‘uma‘u. USGS video by M. Patrick, 08-09-2019.

This video shows steaming from the main pond of water at the bottom of Halema‘uma‘u as captured on Sunday, August 4. Two smaller areas of ponded water were present a short distance east of this spot. Thermal images indicate that the water surface is roughly 70 degrees Celsius (158 degrees Fahrenheit). USGS video by M. Patrick, 08-04-2019.

Mule deer are an important part of the Western landscape and are coveted among big-game hunters throughout the country. These animals draw outdoor enthusiasts to states, such as Wyoming, where nearly 800,000 people hunted, fished, and viewed wildlife, and contributed \$1.1 billion to the state’s economy.

This video discusses the general requirements that will be needed to accomplish a contracted-opening indirect discharge measurement. Approach section, contracted section, and necessary high-water mark locations are described along with scenarios where the method will not be successful. 
 

Satellite imagery shows the rupture and shifting of land near Ridgecrest, CA from the July 2019 earthquakes.

 

Mike Poland, Scientist-in-Charge of the Yellowstone Volcano Observatory, describes activity at Yellowstone during the month of July 2019.

This video describes how to use SAC-GUI in the field to plot high-water mark profiles. Plotting high-water marks in the field is required for most indirect measurement techniques
 

This video describes the field selection of roughness coefficients, or Manning's "n" values. Both the comparative (photos) and analytical (Cowan's) methods are discussed.
 

This video describes how to survey high-water marks and cross-sections for indirect measurements. Included are tips and tricks for getting across non-wadeable sections of the stream.
 

This video goes into detail about where to flag high-water marks and how to survey a slope-area measurement. A simple one-setup Total Station survey is demonstrated.

This video covers the theory behind a slope-area indirect measurement, the most common type of indirect measurement used in the USGS. 
 

This video is a recording of the webinar “Climate Projections as a Way to Illustrate Future Possibilities" that is part of the USGS National Climate Adaptation Science Center (NCASC), in partnership with the National Conservation Training Center (NCTC), 2019 webinar series.

Title: Taking the Pulse of our Planet: A 10-year status report from the USA National Phenology Network

US Navy Captain Paul Dale discusses the collaborative efforts between the USGS and Naval Air Weapons Station, China Lake after the Ridgecrest earthquake sequence. 
 

This video describes how to use the SAC conversion spreadsheet to convert data from a conventional level in angles and distances (polar coordinates) to Cartesian coordinates (northings and eastings). 
 

This is b-roll footage of a ShakeAlert earthquake early warning system seismic station. These seismic stations and sensors are deployed around California and are used to monitor earthquake activity.
 

Science is done by those who "do." Thank you women in science for all your contributions to USGS and the sciences, as a whole.
 

Before landing on the surface of the moon in 1969, astronauts Neil Armstrong and Buzz Aldrin needed a training ground that matched their destination's cratered surface.

Wildlife passages are one tool used to help amphibians and reptiles cross roads safely. Barrier fencing along the road and "turn-arounds" help guide these animals towards the passageways. In this video, a western toad hops back towards the passage after reaching a turn-around structure, following the barrier fencing.
 

This animation shows preliminary results from precise relocation of the Ridgecrest earthquake sequence, through July 6 (UTC), including the foreshock sequence and the first ~20 hours of aftershocks from M 7.1 mainshock.  The animation begins in a map view and then transitions into a rotating vertical slice.  Earthquakes are colorcoded by time of occurrence
