  • Conflict over water resources defines California internationally as much as our Hollywood film stars and Silicon Valley tech wizards.

    From the water wars that pitched residents of Los Angeles against Owens Valley farmers in the 1920s to the modern-day battles over the tunnels project in the Sacramento-San Joaquin Delta, there has been a constant struggle over how to manage California’s precious and limited freshwater.

    Up to now, the focus has been on how to manage surface water, but this is set to change as new legislation, approved in 2014, requires local water agencies to set rules to manage groundwater. Will this herald a new wave of water wars, this time taking the conflict underground?

    If we continue with current approaches to managing water, this is certainly a distinct possibility. Already new blame games are opening up as the drought has led to high levels of groundwater extraction. Parts of the state, such as the San Joaquin Valley, are actually sinking as groundwater aquifers are rapidly depleted. The State Water Resources Control Board has declared that 21 of the state’s groundwater basins and sub-basins are “critically overdrafted.”

  • For more than a million years, the bones lay out of sight, buried under layers of sediment that had accumulated over the eons in San Timoteo Canyon in Riverside County.

    It was only through a lucky twist of fate that they came to light in 2009 when Southern California Edison (SCE) began building the El Casco Substation.

    The discovery ultimately became one of the largest collections of fossils found in Southern California for a geologic period that predates the finds at the La Brea Tar Pits by at least 1 million years.

    Now, after about a year of preparation and nearly four years housed at the Western Science Center in Hemet, the first of the more than 15,000 El Casco fossils will go on display as part of the center’s “Stories from Bones” exhibit opening on Halloween.

    “The fossils tell the story about the life of the animals,” said Alton Dooley, the center’s executive director. “The condition of these bones tell us if an animal was eaten by a predator or was injured or lived to be old and had arthritis.”

  • Long before the Obama administration cracked down on coal-fired power plant pollution, Colorado acted by itself. The state's pollution regulations made it a leader years ago. The state's Democratic governor still favors those rules, but the Republican state attorney general is on the other side and may join a lawsuit against the latest federal steps. [...]

    HOOD: The Obama administration says the plan will save the average family money. It may turn out that the politics over clean power are more complicated than actually producing cleaner energy. Stacy Tellinghuisen is an analyst with the conservation group Western Resource Advocates. She estimates the state is already committed to meeting three-fourths of the final goal.

    STACY TELLINGHUISEN: With no additional actions that aren't already in utilities' plans.

  • OAKLAND -- A magnitude-4.0 temblor that rattled nerves in the East Bay on Monday morning was a very shallow but routine geologic shrug in an area notorious for seismic risk -- and yet another reminder of the threat lurking from a fault that's the Bay Area's most overdue for a major quake.

    A locked-up patch of rocks a mere 3 miles under Piedmont suddenly broke loose along the Hayward Fault, triggering a wake-up call felt from Santa Rosa to Santa Cruz.

    "Because it was shallower than normal, people in the vicinity felt more intensified shaking than usual for an earthquake of this magnitude," said Keith Knudsen, deputy director of the Earthquake Science Center at the U.S. Geological Survey in Menlo Park.

  • While crews begin the arduous task of cleaning up Colorado’s Animas River — where contamination by heavy metals and toxins leaked from an abandoned hard rock mine turning the water orange — thousands of other natural sites across the American West remain at risk from similarly hazardous defunct quarries. The Bureau of Land Management (BLM) estimates that there are currently 2,700 abandoned hard rock mines in need of environmental clean up. Nevada, nicknamed the “Silver State,” has the most, with an estimated 1,100 sites raising environmental concerns.  [...]

    Given how old a lot of the abandoned mines are, Kim Hannula, a geologist professor at Fort Lewis College in Durango, Colorado, said it’s impossible to blame any one party for the environmental dangers they pose.

  • SWARTHMORE, Pa. – Marian Ware Director of Physical Education and Athletics Adam Hertz has announced Karin Brown as the new head swimming coach at Swarthmore College. Brown, who will assume coaching duties for both the men's and women's swimming programs, was most recently the acting head coach at the Massachusetts Institute of Technology. "Karin stood out among a talented pool of candidates," said Hertz. "She has a firm grasp of what it takes to lead this program, and an intellectual curiosity that will complement the culture at Swarthmore. We are very excited that she has chosen to join our family."

  • Variations in the amount of oxygen in Earth's atmosphere significantly altered global climate throughout the planet's history. Efforts to reconstruct past climates must include this previously overlooked factor, a new University of Michigan-led study concludes.

    Oxygen currently comprises about 21 percent of Earth's atmosphere by volume but has varied between 10 percent and 35 percent over the past 541 million years.

    In periods when oxygen levels declined, the resulting drop in atmospheric density led to increased surface evaporation, which in turn led to precipitation increases and warmer temperatures, according to University of Michigan paleoclimatologist Christopher Poulsen.

  • We are particularly pleased to congratulate Kari Cooper '91, Cari Johnson '96 and Peter Reiners '91 who have been named Fellows of the Geological Society Of America.  They will be formally recognized at the Society's annual fall meeting in Baltimore on Nov. 1.

    Society Fellowship is an honor bestowed on the best of the profession by election at the spring GSA Council meeting. GSA members are nominated by existing GSA Fellows in recognition of their distinguished contributions to the geosciences through such avenues as publications, applied research, teaching, administration of geological programs, contributing to the public awareness of geology, leadership of professional organizations, and taking on editorial, bibliographic, and library responsibilities.

    Here are some comments from their nominators:

    Kari M. Cooper (University of California – Davis):
    Kari Cooper has made fundamental contributions to both the development of analytical techniques - most notably involving U-series nuclides - and the understanding of temporal and physical aspects of magma system histories. Her innovative work illuminates, among other key issues, how pre-eruption magma storage works: how long, and in what state?
