ThumbnailWhat’s Drifting Beneath Kauai’s Ocean?

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—at least not here at Makua Beach. Scientists from the U.S. Geological Survey got a detailed picture of the coral reef’s physical environment. Understanding just what these reefs are exposed to and for how long, may help explain why some corals here have succumbed to black band disease.

The movie flies out of San Francisco Bay pausing over a field of large sand waves west of the Golden Gate, and then up to the Bolinas area revealing folded and fractured bedrock. The movie then turns south flying down the coast past Pacifica and towards Half Moon Bay again revealing folded and fractured bedrock beneath the Maverick's surf break. The movie finishes by flying over very complex seafloor of folded bedrock, fault scarps, and ripple scour depressions south of Half Moon Bay and offshore San Gregorio State Beach. The seafloor is colored for depth with reds and oranges representing shallower regions and dark blues and purples representing deeper regions.

This animation shows a virtual fly-through of a detailed, highly accurate three-dimensional map of the lower Elwha River. The data shown were collected using a ground-based lidar scanner, which uses pulses of light to accurately map the riparian environment.

thumbnail of videoExample of lidar data combined with elevation data

Once the point data from lidar are processed and overlaid with digital images, one can virtually “fly” through the scanned area. Landmarks like the Santa Cruz Main Beach volleyball nets, the Santa Cruz Beach Boardwalk, and the mouth of the San Lorenzo River are visible.

thumbnail of videoTurbid Bay: Sediment in Motion

USGS scientists from the Pacific Coastal and Marine Science Center explore how sediment moves across San Francisco Bay tidal flats. The research team deploys a suite of large instrumented tripods to record sediment movements over a six-week period in early 2011. Answers from this work will help determine whether deposition of sediment at high tide is occurring quickly enough to preserve marshes in the face of sea-level rise.

The program also highlights the value and function of the USGS Mendenhall Fellowship Program. The Mendenhall Program at the USGS provides recent PhD graduates an opportunity to conduct cutting-edge research on pressing scientific questions with the guidance and mentoring of established scientists.

Tsunami Preparedness in California

U.S. Geological Survey General Information Product 91 (Requires Flash)

Tsunamis are a constant threat to the coasts of our world. Although tsunamis are infrequent along the West coast of the United States, it is possible and necessary to prepare for potential tsunami hazards to minimize loss of life and property. Community awareness programs are important, as they strive to create an informed society by providing education and training.

These videos about tsunami preparedness in California distinguish between a local tsunami and a distant event and focus on the specific needs of each region. They offer guidelines for correct tsunami response and community preparedness from local emergency managers, first-responders, and leading experts on tsunami hazards and warnings, who have been working on ways of making the tsunami affected regions safer for the people and communities on a long-term basis.

These videos were produced by the U.S. Geological Survey (USGS) in cooperation with the California Emergency Management Agency (CalEMA) and Pacific Gas and Electric Company (PG&E).

Scary Tsunamis

thumbnail of videoVideo by Chris Bauer, KQED QUEST Northern California, first produced on July 28, 2009.
Is California at risk? In 2004, a massive tsunami struck the Indian Ocean. More than 225,000 people were killed. Bay Area researchers raced to the scene to learn everything they could about these deadly forces of nature. The information they gained provides a 'Rosetta stone' for helping to understand the geologic history of tsunamis and when and where they may strike again.

This video from 2009 was later reproduced, to include information and footage from the tsunami in Japan in 2011: On August 2011, a massive 9.0 earthquake generated a tsunami off the coast of Japan. In addition to causing a meltdown at a nuclear power plant and the loss of thousands of lives, the tsunami waves raced across the ocean and struck the California coast, causing tens of millions of dollars’ worth of damage to six counties. A network of buoys monitors signals of tsunami activity at sea.

2008 Glen Canyon Dam High-Flow Experiment, February-March 2008

On March 5, 2008, the Secretary of the Interior pulled the levers at Glen Canyon Dam to release high flows into the stretch of the Colorado River that runs through the 277-mile length of Grand Canyon National Park. In an attempt to distribute sediment from the channel up on to shorelines where it could benefit campers, archaeologic sites, animals, and plants, water was released through Glen Canyon Dam's powerplant and bypass tubes to a maximum amount of approximately 41,500 cubic feet per second for about 60 hours. The experiment was designed “to enhance the habitat in the canyon and its wildlife, and learn more about these complex natural systems,” said Secretary Kempthorne in remarks he made before opening the dam’s jet tubes.

The U.S. Geological Survey's (USGS) Grand Canyon Monitoring and Research Center worked with other Department of the Interior bureaus, the Arizona Game and Fish Department, Northern Arizona University, Utah State University, the University of Wyoming, Idaho State University, Loyola University, Chicago, and other cooperators to conduct a range of research activities to investigate and document potential responses of physical, biological, and cultural resources to the experimental high flow. USGS scientists and their cooperators published high-flow research findings beginning in early 2010.

The 2008 high-flow experiment was a cooperative effort among Department of the Interior bureaus, including the Bureau of Reclamation, National Park Service, U.S. Fish and Wildlife Service, Bureau of Indian Affairs, and USGS.

Public Lecture Videos

The USGS Evening Public Lecture Series events are free and are intended for a general public audience that may not be familiar with the science being discussed. Our speakers are encouraged to thoroughly explain the subject matter being presented, and to define any words or terms that may be unfamiliar to those not having a background or familiarity with the material being presented.

The USGS Evening Public Lecture Series was established in 1990 to provide USGS scientists with a forum for providing the public with current information about USGS research through a series of monthly talks featuring recent developments in the disciplines of biology, geography, geology, and water resources.

Originally conceived to provide customers with an opportunity to interact live with USGS scientists while gaining information about "Earth Science in the Public Service", the Menlo Park Campus Evening Public Lecture Series continues to provide the original public service, while now providing remote live access through video streaming on the Internet, and on-demand access to archived talks following each lecture.

Our ongoing goal continues to be providing customers with solid scientific information presented in a way that can be appreciated by those not necessarily having a background in the sciences, and to create a better understanding of the importance and value of "Science for a Changing World".
