New technologies in the form of Interferometric Synthetic Aperture Radar (InSAR) and the Global Positioning System (GPS) have helped scientists determine that fluid-like flow occurred just below the earth’s crust in the first few months following two recent large California earthquakes.

Imagine the world’s oceans teeming with whales, sea turtles and fishes, with shellfish so abundant they posed a hazard to navigation. Only in a Jules Verne classic fantasy? Not so. A group of scientists from several research institutions has recently depicted that such rich ocean life existed in the not-so-distant past. 

Last year up; this year down, but the number of sea otters in California remain roughly stable, neither increasing or decreasing rapidly, according to the scientists who study them. Still, a lack of sustained growth worries researchers and sea otter watchers.

A newly released United States Geological Survey paper indicates that a significant zone of genetic mixing is occurring between northern spotted owls and California spotted owls, particularly in extreme northern California and southern Oregon.

While some folks may make a special effort to ride their bikes to work on the appointed day, May 17, it will be just another day to sit back and take it easy for John Fisher, who lives in Fremont and works as a cartographer at the U.S. Geological Survey in Menlo Park.

A team of university, government, and private biologists have successfully spawned white abalone, a crucial step in developing a white abalone hatchery. Stocking of hatchery-reared white abalone is one of the possible strategies that may be used to rebuild the white abalone population, which is being considered for listing as an endangered species.
