Permanent Site: C1 West Transect; Depth: Meters (Feet); Distance from river mouth: 0.7 Kilometers (0.4 Miles); Pre/Post Dam Removal: 10 months post-dam removal; Lat/Long: 48.14525225,-123.57361291; Site Description: Substrate is entirely sand. Brown seaweeds are absent and only a few small red seaweeds remain (0:46, 0:56 seconds).

Over the last several decades, non-native species have continued to invade sensitive ecosystems in the United States. Two high-profile species, Asian carp in the Midwest and Burmese pythons in the Everglades, are the focus of much attention by decision makers, the public and the media.

The Mekong is one of the world's longest rivers connecting six Asian countries, China, Myanmar, Laos, Thailand, Cambodia, and Vietnam. People and fish, as well as many other species in this biologically rich region, are directly connected to the river, so that what impacts the river also impacts them.

Scuba-diver scientists from the U.S. Geological Survey explore and catalogue the effect of released sediment on marine life following the nation's largest dam removal effort.

Hi, my name is Kaitlyn Bednar but everyone calls me Kati. I am currently a Student Trainee Hydrologist with the California Water Science Center (CAWSC) in Sacramento. I am also a full-time geology and geography student at California State University of Sacramento, and a part-time student at American River College within their G.I.S. certificate program.

--modern sonar reveals hidden hazards and resources

In preparation for marine work in the cold waters off Alaska professionals from academia, industry and government must, every few years, take an offshore survival class to increase their chances of survival in the event of a seafaring mishap.

"Science for a Changing World" is a short film (eight minutes) describing a brief history of the USGS and the significance of USGS work and mission in today's world and its value in the past.

Landslides occur in all 50 states and U.S. territories, and cause \$1-2 billion in damages and more than 25 fatalities on average each year. USGS scientists aim to improve our understanding of landslide hazards to help protect communities and reduce associated losses.

On May 25, 2012, the USGS Great Lakes Science Center Dive Team documented first ever egg deposition by State- and Provincially-threatened lake sturgeon on a man-made spawning reef constructed in the Middle Channel of the St. Clair River Area of Concern, while the reef was still being constructed.

This Quicktime movie shows the impressive spattering at the western margin of the lava lake at Halema‘uma‘u. The continuous spattering is often punctuated by bursts which throw lava onto the ledge (left portion of image), and this accumulating lava is building a spatter rampart.

USGS geologist, Angie Diefenbach, describes how she uses GIS, (Geographic Information Systems) software to study volcanic eruptions and their impacts on society.

This Quicktime movie shows spattering that is typical at the margins of the lava lake in Halema‘uma‘u crater. The slow migration of the lava lake surface is normally towards the area of spattering, where the lava sinks back into the magmatic system. Spatter in this clip is being thrown about 5-10 meters (yards) in height.

Photogrammetry is the science of making precise measurements by the use of photography. USGS geologist Angie Diefenbach describes how she uses a digital camera and computer software to understand the growth rate of lava domes during a volcanic eruption.

Debris flows are hazardous flows of rock, sediment and water that surge down mountain slopes and into adjacent valleys. Hydrologist Richard Iverson describes the nature of debris-flow research and explains how debris flow experiments are conducted at the USGS Debris Flow Flume, west of Eugene, Oregon.
