Sources of Fecal Indicator Bacteria in Urban Streams and Ocean Beaches, Santa Barbara, California; Fecal indicator bacteria (FIB) concentrations in urban streams and ocean beaches in Santa Barbara, Calif. can exceed water-quality standards for recreational water. During low flow, high FIB concentrations in urban streams were associated with point discharges from storm drains, and concentrations in urban streamflow varied three-fold over the course of a day as a result of small variations in...

Our First Sip of Seawater

submitted by: ucsandiego

There's one way Scripps Institution of Oceanography at UC San Diego researchers see the future of desalination in California going. Before a regulatory structure can take shape to govern how seawater is treated and transported to a thirsty public, a gubernatorial order will be handed down that fast-tracks the construction of desalination plants during an episode of extreme drought when battles over water turn violent. Ecological casualties would be assured.

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...
