This time-lapse video shows lateral erosion of a salt marsh in the Grand Bay National Estuarine Research Reserve, part of an embayment near the city of Pascagoula, Mississippi, on the US Gulf coast. Wave action over the course of 6.5 months led to about 1.5 meters of erosion.

This video focuses on the National Aeronautics and Space Administration’s (NASA) Terra and Aqua Moderate Resolution Imaging Spectroradiometer (MODIS) Version 6 land data distributed by NASA’s Land Processes Distributed Active Archive Center (LP DAAC).

The seasonal progression of global vegetation is driven by the tilt of the Earth's rotational axis and its annual orbit around the Sun. In turn, global seasonality drives major changes in important environmental factors such as global atmospheric carbon dioxide concentrations.

Did you know that tree canopy cover can be measured from space? The Moderate Resolution Imaging Spectroradiometer (MODIS) sensor onboard NASA’s Terra and Aqua satellites can do just that by providing data that are used to calculate Leaf Area Index (LAI).

This video demonstrates how to establish permanent reference points and markers at a well site.
 

This video will provide a brief history and purpose for one of the oldest streamgages in Indiana. The gage is at the Wabash River at Lafayette, Indiana. The site number is 03335500. This video was produced at the request of the West Lafayette Parks Department where this historic gage is located.

This video demonstrates how to measure total well depth below land surface using a weighted, graduated steel tape.

The Department of the Interior Pacific Islands Climate Science Center and the University of Hawaiʻi at Hilo developed and hosted a Climate Change Boot Camp that showcased collaborative research efforts within UH Hilo’s Tropical Conservation Biology and Environmental Science graduate program that are driven by local natural resource managers across Hawaiʻi Islan

This video provides an overview of the USGS Fractured Rock Geophysical Toolbox Method Selection Tool. The Fractured Rock Geophysical Toolbox Method Selection Tool (FRGT-MST) is an Excel-based tool for identification of geophysical methods most likely to be appropriate for project goals and site conditions.

Take a short look at a low cost phosphorus removal water filter the USGS has been working on for several years. 
 

This video, at 50x speed to illustrate the motion of the lava lake surface, shows typical lava lake activity within Halema‘uma‘u Crater. Lava upwells in the northern portion of the lake (left side of image), with most of the lake surface flowing towards the south (right side).

As you watch this VIDEO CLIP, note the rocky ledge (yellow arrow) at the bottom of the webcam image. At 6:58 a.m., HST, today, this large slab of the summit vent wall, located directly below HVO's HMcam, collapsed.

The new Great Salt Lake breach was opened on Dec. 1 by the Union Pacific Railroad Company. This created a new opening between the north and the south arm of the lake, allowing water to flow between the two sides. This time-lapse video shows the breach opening, which took about two hours.

Presents descriptions of the USGS Precipitation Runoff Modeling System (PRMS) Surface-Runoff modules, which compute Hortonian surface runoff, soil infiltration, and impervious surface and surface depression storage and flows.

VIDEO CLIP captured by HVO webcam: At 11:59 a.m., a rockfall from the south wall of Halema‘uma‘u Crater triggered a small explosive event in the summit lava lake. The explosion threw spatter (fragments of molten lava) onto the rim of the crater, mostly to the west of the former visitor overlook.

This VIDEO CLIP shows a cloud of ash and spatter being thrown from the summit lava lake during today's explosive event. The images were captured by an HVO webcam located on the rim of Halema‘uma‘u Crater, just above the rockfall area.

Ecological Stressors: It's a Lot of 'WERC'
"There's is no place like California" by A. Keith Miles, Center Director, USGS Western Ecological Research Center

Highlights of the science of the USGS Western Ecological Research Center: 

Approximately 25 to 50 percent of a living tree is made up of water, depending on the species and time of year. The water stored in trees has previously been considered just a minor part of the water cycle, but a study by University of Alaska Fairbanks scientists with support from the DOI Alaska Climate Science Center shows otherwise.

This video shows activity in the summit lava lake in Halema‘uma‘u Crater. Spattering like this is common in the lake, and this video shows the view from the rim of Halema‘uma‘u (closed to the public due to volcanic hazards). This spattering has recently been visible from the Jaggar Overlook inside Hawai‘i Volcanoes National Park (open to the public).
