Recorded June 1, 2019 - August 18, 2019: Video shows a series of photos taken every hour during daylight hours in the summer of 2019. The camera looks westward along the coastal bluffs of Barter Island, located on Alaska’s North Slope.

This video shows a close-up of the water pond at the bottom of Halema‘uma‘u on August 13, 2019. Steaming from the water surface shows the shifting winds over the pond.

This video goes into detail about surveying high-water marks, various aspects of bridges, and cross sections for the contracted-opening method. 
 

This video shows a close-up of the ponded water at the bottom of Halema'uma'u. Yesterday, the separate ponds joined into a single elongate pond. The water level has continued to slowly rise.

Iceland had 269 named glaciers as of the year 2000 but ice has retreated in the face of warming temperatures. By 2014, OK Glacier in western Iceland had lost so much mass that it was no longer considered one at all. Icelanders now refer to it simply as OK, the name of the volcano upon which it rests.

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).
