November public lecture, "The Science of Good Taste -- Geology, Wine and Food"presented by Larry Meinert, Ph.D.

Ashley Liddiard works for the U.S. Geological Survey on the Crustal Imaging and Characterization Team in Lakewood, Colorado. She first started at the USGS in February 2010 as a student at Regis University.

This presentation is a part of the ‘NCCWSC Climate Change Science and Management Webinar Series‘, developed in partnership by the USGS National Climate Change and Wildlife Science Center and the FWS National Conservation Training Center.

Southern California's fire ecology is unlike that of anywhere else in the United States. Fire control strategies developed for mountain forests don't have the same results here. So can science help uncover new answers to help Southern California communities manage and live with wildfires?

This Quicktime movie shows a time-lapse sequence of the lava lake captured by a thermal camera on the rim of Halema‘uma‘u crater. The sequence is shown at a speed of about 30 times actual. By viewing the sequence at this speed, spotting the upwelling area in the lake is easier than in a still photograph.

Quicktime video, taken from the east rim of Pu‘u ‘Ō‘ō crater, showing the small lava lake that is active in the northeast portion of the crater floor. Unsteady gas escape along the lake margins drives low-level spattering and undulations of the lake surface.

Video taken during today's helicopter overflight of Halema‘uma‘u, showing the active lava lake at a very high level (described in more detail in the caption above). Vigorous spattering on the lake margin emits a thick plume of gas.

Quicktime movie showing lava flowing through the active lava tube on the pali.

Video zoomed in on the spattering at the west edge of the lava lake in the 'overlook' vent in Halema‘uma‘u.

Heat from the high lava lake level in the 'overlook' vent in Halema‘uma‘u is causing the walls of the vent above the lava surface to expand and fracture. This is the source of the cracking and booming noises emanating from the vent in recent days.

This video shows spattering at the west edge of the lava lake in the 'overlook' vent in Halema‘uma‘u Crater. The crackling and popping noises are from fracturing of the rocks composing the walls of the vent caused by thermal expansion.

Working at the USGS can be fun. These student employees were given wonderful opportunities and made lasting friendships while working at the USGS.

Kitty Kolb, a geographer for the U.S. Geological Survey North Carolina Water Science Center, had a lot of fun last year working with the hydrologic benchmark monitoring team in the Great Smoky Mountains National Park. During her day, Kitty worked to collect algae and aquatic insect larvae.
