Faith Fitzpatrick (U.S. Geological Survey) and Paul Lohmiller (GRAEF-USA, Inc.) talk about the communities and groups that make up the successful Menomonee River Action team in Milwaukee, Wis.

Faith Fitzpatrick (U.S. Geological Survey) and Dave Fowler (Milwaukee Metropolitan Sewerage District) describe how the deep tunnel system in the Milwaukee area has allowed enough flood storage to be able to take out the cement-lined channel and recreate a more natural riffle-pool type of channel with improved fish habitat and fish passage.

Faith Fitzpatrick (U.S. Geological Survey) and Theresa Caven (City of Brookfield) talk about how the City of Brookfield near Milwaukee, Wisconsin actively participates in the highly successful Menomonee River Action Plan team.

Cheryl Nenn (Milwaukee Riverkeeper) and Jeff Martinka (Southeastern Wisconsin Watersheds Trust, Inc.) discuss the power of the people in making things happen for Menomonee River restoration projects.

movie shows a channelized flow that broke out of the lava tube early this morning at the base of the pali, west of Kalapana. Even after traveling through the lava tube system for almost 10 kilometers (about 6.2 miles), the lava is sufficiently hot to be extremely fluid, and moves swiftly downslope. For scale, the channel is about 2 meters (about 2 yards) wide.

movie shows the flow that began erupting in Pu`u `Ō `ō crater this morning. The primary vent for the flow was producing small pulsating spattering that had built a small rampart on its south side. The final portion of the video is shown at x10 speed with a wide view, and shows how the spattering vent is supplying the flow.

The video relates how a team of scientists conducted rapid response sampling of coastal environments before any oil had reached land, following up in October 2010 with post-landfall sampling for comparison.

This video provides an overview of direct and indirect effects of increases in atmospheric CO₂ on coastal wetlands using a salt marsh-mangrove community as an example.

A caldera is a large, usually circular volcanic depression formed when magma is withdrawn or erupted from a shallow underground magma reservoir. It is often difficult to visualize how calderas form. This simple experiment using flour, a balloon, tubing, and a bicycle pump, provides a helpful visualization for caldera formation.

movie captures a short period of successive littoral explosions at the Puhi-o-Kalaikini ocean entry, where lava exiting the tube enters the water. The explosions were throwing ejecta up to about 20 meters. The video was taken with a high zoom factor from the top of the sea cliff, well away from the entry point and not on the lava delta.

One hour recording of a lecture and slide presentation about White-Nose syndrome in bats, by Peter Youngbaer
Sponsored jointly by the USGS and the San Francisco Bay Chapter of the
National Speleological Society, Mr. Youngbaer addressed the topic of
White Nose Syndrome, a fungus associated with decimation of bat populations

On September, 24, 2010 The USGS briefed Congress, the media and the public on a new USGS study documenting nutrient concentrations in the Nation's water resources, key sources of nutrients, potential effects on humans and aquatic life, and changes in concentrations since the early 1990's.

The lava lake deep within the vent cavity at Halema`uma`u crater remains active, with ongoing degassing and circulation of lava. This Quicktime movie shows the view in the vent today with a thermal camera, and the video is set at x4 speed to better show the slowly moving lava surface.
