This video demonstrates how to select an appropriate location for an indirect measurement. Theory and initial reconnaissance are discussed. 

This video shows how to survey a slope-conveyance indirect measurement using a conventional optical or digital level. 
 

This video details how to measure various aspects of a box culvert for a culvert indirect measurement. The video includes tips and tricks for measuring the geometry, wingwall angles, and entrance types including rounded or beveled entrances.
 

This video gives an overview of what it mean to be an International Cooperator, including information on what is an International Cooperator, who represents the International Cooperator community, what are the benefits of being an International Cooperator, and what does it mean to be an International Cooperator.

This video provides an introduction to the slope-conveyance method of indirect measurement. Theory and background are described as well as high-water mark and cross-section placement. 
 

Tribes have been actively engaged in efforts to anticipate and respond to climate impacts on their natural and cultural resources.

This animation takes the viewer down the Glen Canyon from Bullfrog Bay to the Rincon, in the Glen Canyon National Recreation Area. New high resolution multibeam bathymetry collected by the USGS in 2018 shows the submerged portions of Glen Canyon. 
 

The Marsh Arabs of southeastern Iraq have spent millennia traversing the waterways at the confluence of the Tigris and Euphrates rivers. The recent history of those wetlands, however, has been one of forced loss and uneven recovery. 

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

 

This is an animation showing the changing conditions of USGS streamgages from January 1, 2019 to June 1, 2019. The conditions shown range from the driest condition seen at a gage (red open circles) to the wettest (blue closed circles). There is also a purple ring added to indicate gages that are flooding.

USGS Storm Tide Sensors are specialized scientific instruments used to measure the depth and duration of storm surge during coastal storms. The data these sensors collect before, during and after a storm will help public officials assess storm damage, and improve computer models used to forecast storm surge and coastal change.

USGS scientists are studying water-quality conditions and harmful algal blooms—known as HABs—in Owasco, Seneca and Skaneateles lakes in New York. The USGS monitoring effort will provide a better understanding of HAB growth and severity and allow for near instantaneous detection of changing water-quality conditions that might be indicative of HAB development.

Scientists with the USGS Yellowstone Volcano Observatory use satellite and aerial imagery to map hot springs, geothermal vents, and geysers at Yellowstone National Park. They recently found an entirely new thermal area miles from the nearest trailhead. Landsat 8's thermal infrared sensors captured the change in a nighttime image from April of 2017.

This animation is the third video in a series explaining different aspects of the Phragmites Adaptive Management Framework (PAMF). This video focuses on the machine learning model that PAMF uses to systematically learn from participant's data and then provide site-specific management guidance in return.

This timelapse sequence of webcam images over a 24-hour period shows a typical day at the summit of Mauna Loa. The webcam (MLcam) is located on the northeast rim of Moku‘āweoweo, Mauna Loa's summit caldera. This sequence begins in the dark, with the moon rising (white dot at left in images), then brightens as the sun rises.

In the Arctic, rivers are often thought to freeze completely during winter. Since fish need liquid water to survive, there are few places where they can live. Fish usually inhabit deep river channels and areas where springwater enters a stream.

• How can we use images from space to help us understand changes to our coasts, rangelands, forests and wildlife habitats?
• How can they help to predict future changes?
• What more can we learn from advances in earth observing technologies?

The Moderate Resolution Imaging Spectroradiometer (MODIS) sensor is located aboard NASA’s Terra and Aqua satellites. These data are crucial for studying changes that have occurred on the surface of the Earth, including during times of drought.
