This video shows how to document the following sensor types: pressure transducer, wire-weight gage, staff gage, reference point, and crest stage gage (CSG). In this example, measuring point elevations for the reference point and crest stage gage are configured in SiteVisit.

This video shows how to document a gage height of zero flow (GZF) inspection.

This video shows how to document high-water marks.

This video shows how to document a stilling-well inspection.

This video provides an overview of the miscellaneous information (Misc. Information) task.

This video shows two methods of uploading SWAMI files into SiteVisit.

This video provides an overview of how to use stylesheets to view SWAMI data.

This video shows how to install the UNIX scripts to create files of gaging stations, stage-discharge rating curves, station sensors, and meters that are required when using SWAMI.

This video shows how to document a discharge measurement that is an estimate.

This video shows how to document a discharge measurement made using a flume.

This video shows how to document a mid-section discharge measurement made with an ADV. The ADV data is imported in the field.

This video provides an overview of staging ADCP and ADV measurements in SWAMI.

"1964 Quake: The Great Alaska Earthquake" is an eleven minute video highlighting the impacts and effects of America's largest recorded earthquake. It is an expanded version of the four minute video "Magnitude 9.2". Both were created as part of USGS activities acknowledging the fifty year anniversary of the quake on March 27, 2014.

This webinar is presented by Jennifer Cartwright and Bill Wolfe of the USGS Tennessee Water Science Center. In the Southeastern U.S., "insular ecosystems" may be particularly vulnerable to ecological effects from climate change.

Video presents geospatial capabilities in ScienceBase, including file handling, inline viewing, generated services, as well as, explanation of technologies and databases behind ScienceBase.

This Quicktime movie shows a time-lapse sequence of activity at the northeast spatter cone in Pu‘u ‘Ō‘ō crater on February 9-10. Rapid fluctuations in the height of the lava pond are caused by gas pistoning, which is the gradual buildup and release of gas in the pond. Mauna Kea is visible in the upper right portion of the frame.

This Quicktime movie is a time-lapse sequence from a camera in the HVO observation tower, and shows one week of activity at Kīlauea's summit vent in Halema‘uma‘u Crater. The sequence starts on February 3 at 12:01 am and ends on February 9 at 11:59 pm.

This Quicktime movie shows typical activity at the summit lava lake. Spattering at the summit lava lake has been common over the past several years, and today's winds provided a clear view of the primary spatter area on the lake margin. The lava lake today was about 50 m (160 ft) below the floor of Halema‘uma‘u Crater.

This Quicktime video shows a time-lapse sequence spanning from dawn to dusk on Tuesday, January 28, using images collected by our webcam near the summit of Mauna Loa Volcano (13,680 ft above sea level).
