Bears rub on many objects other than trees. This clip shows a grizzly bear with two yearlings rubbing on a wooden bridge on a decommissioned forest road. Barbed wire is attached to the wooden bridge beams and the bear rub tree next to the bridge to collect bear hair. This footage is still photos from a remote camera that have been stitched together in sequence.

Coastal Louisiana wetlands make up the seventh largest delta on Earth, contain about 37 percent of the estuarine herbaceous marshes in the conterminous United States, and support the largest commercial fishery in the lower 48 States.

Faith Fitzpatrick (U.S. Geological Survey) and Joe Berg (BioHabitats, Inc.) describe base-flow channels and sand seepage wetlands in a wetland complex at an old millpond setting along a highly urban section of Howards Branch. Recreated baseflow channels enhance changes in width with increased stormwater flow.

Faith Fitzpatrick (U.S. Geological Survey), Ronald Bowen (Anne Arundel County Department of Public Works), Kevin Smith (Maryland Department of Natural Resources), and Keith Underwood (Underwood and Assoc.) talk about recreating an Atlantic White Cedar wetland at an old millpond setting along a highly urban section of Howards Branch.

USGS biologists are using GPS technology to track carnivores as they cross the highways of urban Southern California.

This Quicktime movie shows the recent uplift of the lava lake and crater floor in Pu‘u ‘Ō‘ō crater, captured by a thermal camera on the crater rim. The time-lapse movie spans July 9 to today, July 18, and is looped several times. The uplift was continuous between July 9 and 16, but had stalled by the 17th.

Between June 16 and June 23, 2006, the floor of the pit containing the "Drainhole" vent collapsed, revealing a small lava pond about 12 meters across. Gas pistons continued to occur but were much larger, as is evident when comparing this movie to the others with the same title.

The Nation relies on oil and gas to power its economy, and unconventional gas is the fastest-growing energy resource in the United States. The U.S. Geological Survey is the authoritative, unbiased source for assessments of the world's oil and gas endowment. Come learn how these exciting new energy resources may contribute to the energy mix.

The Mekong is one of the world's great rivers cascading through six Asian countries from the Tibetan Plateau to the South China Sea, connecting China, Myanmar, Laos, Thailand, Cambodia and Vietnam. How one country uses or changes the waters of the Mekong upstream can have important implications for the health of the river and people downstream.

Today on the USGS CoreCast we explore what impact emerging contaminants have on the health and development of aquatic wildlife.

June 3, 2006, 21:00:05 to June 4, 2006, 01:00:04) This movie sequence is a third example of gas pistoning (described below) captured by the same camera used to compile the other "Gas pistons within the Drainhole vent at Pu‘u ‘Ō‘ō" movies .

(June 3, 2006, 06:00:03 to 13:20:03) This movie sequence shows another example of gas pistoning (described in "Gas pistons withing the Drainhole vent at Pu‘u ‘Ō‘ō", 06-02-2006) captured by the same camera used to compile the previous movie.

A movie of the erupting vent on the east wall of Pu‘u ‘Ō‘ō Crater. The movie begins with a cascade of lava filling the southern opening on the east wall and ends at the spattering source, which is producing the cascading flow.

Movie of the lava lake in Kīlauea's summit vent in Halema‘uma‘u crater minutes after a slice of the vent wall had plunged into the lava. The lava lake is roiling violently as the recently added wall debris is digested by the lava. Slabs of rock can be seen breaking loose from the base of the overhanging vent wall and falling into the lava.

Quicktime movie showing spattering at the south edge of the lava lake in the vent at Halema‘uma‘u.

Movie showing the second of five large collapses within Kīlauea's summit vent on the floor of Halema‘uma‘u. The collapse was captured by a Webcam located on the rim of Halema‘uma‘u directly above the erupting vent.
