Permanent Site: H1 East Transect; Depth: 5.8 Meters (19.1 Feet); Distance from river mouth: 2.4 Kilometers (1.5 Miles) east; Pre/Post Dam Removal: 6 years post-dam removal; Lat/Long: 48.1479177,-123.53472865; Site Description: This is a shallow site and one of the farthest removed from the effects of the sediment plume outside of the control sites.

VIDEO: Kīlauea Volcano's Kamokuna ocean entry. Today, the "firehose flow" could be clearly seen from the public lava viewing area, 800 meters (about one-half mile) east of the ocean entry, in Hawai‘i Volcanoes National Park.

VIDEO: The section of sea cliff above the ocean entry collapsed today at about 12:55 p.m. The sea cliff had become increasingly unstable as a large crack 5–10 m (16–33 ft) inland of the ocean entry had more than doubled in width, from 30 cm (1 ft) to 70 cm (2.5 ft), over the past several days.

What does it take to become an ocean engineer? Here is the path that USGS Gerry Hatcher took.
 

Residents and visitors both revel in Kauai’s lush landscape, and beneath its seascape. However, it’s underwater where things don’t look so healthy. Scientists from the U.S. Geological Survey put together a detailed picture of the physical environment of the coral reefs at Makua Beach.

This video clip shows the open lava stream pouring into the ocean. Frequent littoral explosions throw bits of lava to heights of over 27 m (30 yards).

The open lava stream continues at the Kamokuna ocean entry. Today, the stream was remarkably steady, but produced pulsating littoral explosions where the lava impacted the water.

A presentation on "Unusual Sources of Tsunamis From Krakatoa to Monterey Bay" by Eric Geist, USGS Research Geophysicist

- Not all tsunamis are generated by earthquakes.
- Tsunamis can be caused by volcanoes, landslides, and even atmospheric disturbances
- Data from tide gauges can help unravel the complex physics of these sources

This video clip shows the lava stream - about 1-2 m or yards wide - pouring out of the tube into the Pacific Ocean, triggering pulsating explosions that are throwing bits of lava onto the top of the sea cliff.

The June 2016 Fish Fire burned over 12 km^2 in Los Angeles County, California. After the fire, the USGS installed an automated rain-triggered camera to monitor post-wildfire flooding and debris flow in a small canyon above the Las Lomas debris basin in Duarte. This video shows the peak flow triggered by an intense rainstorm on January 20, 2017.
 

This video clip shows spattering that was active along the southeast margin of the lava lake in Halema'uma'u Crater at Kilauea's summit. Rising lava levels over the past day provided improved views of the lake surface from the Halema'uma'u Crater rim (closed to the public due to ongoing volcanic hazards).

This webinar presentation was conducted as part of the Climate Change Science and Management Webinar Series, hosted in partnership by the USGS National Climate Change and Wildlife Science Center and the FWS National Conservation Training Center.

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.
