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.

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

Along the Atlantic Coast, a 2000+ ft deep hole has been drilled by the USGS to assess the issues of groundwater pumping, relative sea-level rise, and land subsidence. This video shows the drilling of the first extensometer to measure land subsidence in the North Atlantic Coastal Plain in 30+ years.

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.
