This video podcast highlights 50 years of photographic documentation of coral reefs in the Florida Keys.  The photographs show 5 decades of changes that have taken place in both the size and the types of corals that were present at several coral reef sites from the early 1960s to today.  The images capture events such as the appearance of coral disease and

USGS - GLSC SCUBA divers search Flathead Lake, MT for zebra mussels after water quality samples detected the presence of a larval stage.  The dive team did not find evidence of adult zebra mussels.

The USGS recently constructed a computer model of groundwater in the Mississippi embayment. This model was used to simulate the rise or decline of water level in a deep aquifer. Water from this deep aquifer is utilized to meet the industrial and public supply needs in the area.

The USGS recently constructed a computer model of groundwater in the Mississippi embayment. This model was used to simulate the rise or decline of water level in a shallow aquifer. Water from this shallow aquifer is utilized by the agricultural based economy in the area.

Faith Fitzpatrick (U.S. Geological Survey) and Gail Epping Overholt (University of Wisconsin-Extension Basin Educator) talk about bringing people together to improve the Menomonee River watershed through the Menomonee River Action Plan.

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.
