Communicating NRDAR Science: Translating Contaminant Data to Art
The NRDAR science webinar series highlights expertise, data, and information developed for NRDAR cases or for potential new methods application. In this presentation, Mallery Quetawki describes her work turning contaminant data into art for communicating science to Native American communities.

B-Roll of Lees Ferry
A collection of video for use in products related to the USGS's streamgage at Lees Ferry. The USGS installed the Lees Ferry gauge 100 years ago, and the data collected since have become critical to monitoring water availability in the West.

Kīlauea Summit Eruption Thermal
This thermal video shows the lava lake in Halema‘uma‘u, at the summit of Kīlauea. Lava is supplied from the western fissure, in the upper left portion of the video. Small vent openings atop the western fissure exhibit rhythmic gas puffing. The video is shown at 5x speed.

Managing Post-Fire, Climate-Induced Vegetation Transitions
Warmer, drier and longer fire seasons in the Northwest have led to larger and more frequent wildfires.

Kīlauea summit — webcam time-lapse
This time-lapse sequence shows the growth of the lava lake in Halema‘uma‘u, at the summit of Kīlauea. The sequence starts on December 28, about a week after the start of the eruption and ends on March 10, 2021. The lake rises rapidly at first but then eventually slows down as the eruption rate gradually declines.

Mount St. Helens—Lives Changed, Lessons Learned, Legacies of 1980
How did the May 18, 1980 eruption of Mount St. Helens change peoples’ lives? Carolyn Driedger talks about events that led up to the 1980 eruption and influenced scientists’ response to it, as well as what happened on May 18, and how the eruption changed people's lives and professions.

Perched Pond Collapse in Halema‘uma‘u, Kīlauea Summit (Mar 7, 2021)
This timelapse sequence shows several hours of activity in the lava lake in Halema‘uma‘u, at the summit of Kīlauea. Between March 5-7 a small lava pond developed near the vent. At approximately 1 pm on March 7, the levee of the pond collapsed, allowing the pond lava to drain into the main lake.

East Rift Zone overflight (March 4, 2021)
A routine helicopter overflight of Kīlauea's East Rift Zone allowed Hawaiian Volcano Observatory geologists to conduct an updated visual and thermal survey. This video is shown at 5x speed, and moves from west to east. At the western end of the region affected during the 2018 eruption, steaming remains in residential areas west of Highway 130.

Fly-Through of Halema‘uma‘u Crater Model (March 4, 2021)
Visual photographs taken during helicopter overflights of Halema‘uma‘u Crater are used to create 3D models of the crater. This technique is called structure-from-motion photogrammetry and uses the multiple perspectives captured in dozens of photos to reconstruct the crater shape.

A routine helicopter overflight of Kīlauea's East Rift Zone allowed Hawaiian Volcano Observatory geologists to conduct an updated visual and thermal survey. This video is shown at 2x speed and circles Pu‘u ‘Ō‘ō, the vent region for the East Rift Zone eruption between 1983 and 2018. No major changes were observed in Pu‘u ‘Ō‘ō.

How USGS Streamgages Work
This video explains how streamgages are used to measure the height and flow, or speed, of streams. By monitoring the height and flow of streams, the people who manage water infrastructure can have advanced noted of when the water is rising and how fast it’s coming.

"Not all eruptions are Armageddon" - Yellowstone Update for March 2021
Mike Poland, Scientist-in-Charge of the Yellowstone Volcano Observatory, debunks the misconception that if Yellowstone were to erupt, it would be Armageddon. In fact, the most common form of eruptive activity at Yellowstone is a lava flow, and even those aren't that common. They happen only once every few tens of thousands of years.

Image of the Week - Glacial Changes in Chile
The remote ice fields of southern Chile have seen some dramatic change over the past three decades; change made clear by Landsat's deep archive of imagery. In 1987, the terminus of Erasmo Glacier was at the end of a low sloping valley. By 2015 it had retreated almost 3 kilometers, and formed a water body referred to as a proglacial lake.
