Crustal Structure of the Caucasus/Caspian region using gravity and receiver functions - Jason Ricketts; B.S. Candidate, Advisor Dr.Rob Mellors: The area west of the South Caspian basin is an area of complex and uncertain tectonic structure. Thick sediments within the Kura Depression mask the basement and its subsurface geology is poorly constrained. Forward modeling of receiver functions provides initial constrains. However, a good match is sometimes difficult due to the thick sediments....

Paleoenvironments, Paleoecology, and Exceptional Preservation in Burgess Shale-type Deposits - Robert Gaines; Department of Geology, Pomona College: Cambrian Burgess Shale-type (BST) deposits occur worldwide and offer a remarkable window on the initial Phanerozoic radiation of the Metazoa. However, BST deposits also represent significant deviations from the constraints that govern the typical operation of the fossil record. These deviations remain to be adequately accounted for,...

How to Use Portable Steam Collector

submitted by: drscottkelley

This video shows a demonstration of how to use a custom made steam collector designed to condense steam from geothermal vents (aka., fumaroles). This device was used used to collect samples of halophilic Archaea from fumaroles around the world, work which was published in:

Ellis, D., R.W. Bizzoco, and S.T. Kelley. (2008) Halophilic Archaea identified in fumarole steam vapor from vents around the world. Environmental Microbiology, 10: 1582-1590.

Stromatolites: Myths and Legends; Stromatolites are classically interpreted as “organo-sedimentary structures”, where layers and doming/branching result from microbial mats. As such, they could be considered quintessential ‘astrobiologic’ structures—a stromatolite, as a macroscopic manifestation of microbial processes, would be much easier to image remotely (on Mars, for example) than a microbe. While there is no doubt that some (perhaps most) stromatolites on Earth were formed...

Utilization of Geological Techniques to Help Solve an Archaeological Puzzle: When Did People Arrive in North America? Eleanora (Norrie) Robbins Department of Geological Sciences San Diego State University Knut Fladmark hypothesized that as soon as boat technology was developed 40,000 years ago, people probably traveled the oceans. The 40,000-year-ago shoreline is now below 150-160 ft (50 m) of water and an unknown thickness of sediment. So evidence for boat transport by maritime...
