West Coast Scientists Recommend Immediate Action Plan to Combat Ocean Acidification

By Kat Kerlin

Global carbon dioxide emissions are triggering permanent changes to ocean chemistry along the West Coast. Failure to act on this fundamental change in seawater chemistry, known as ocean acidification, is expected to have devastating ecological consequences for the West Coast in the decades to come, warns a multistate panel of scientists, including two from UC Davis Bodega Marine Laboratory.

Their report, issued this week, urges immediate action and outlines a regional strategy to combat the alarming global changes underway. Inaction now will reduce options and impose higher costs later, the report said.

Tide pools at the front line of ocean acidification

Beloved by beach goers, tide pools are also important ecological zones that provide shelter and food for many plants and animals.

Marine life living in tide pools are vulnerable to rising acid levels in seawater, according to new research from UC Davis, the Carnegie Institution for Science and UC Santa Cruz published March 18 in the journal Scientific Reports.

UC Davis joins UC Water effort to improve state’s water security

By Kat Kerlin

It’s hard to manage what you don’t measure.

UC Davis is playing a major role in solving California’s biggest water woes by joining forces across the UC system. The UC Water Security and Sustainability Research Initiative aims to account for all of California’s water, better understand how and where it flows, and help demonstrate how water can be managed differently to allow for greater water security.

Refael Klein flies the Aggie flag at the South Pole

If you think it’s been a bit chilly in the Sacramento region this week, spare a thought for UC Davis alumnus Refael Klein, lieutenant junior grade in the Commissioned Officer Corps of the National Oceanic and Atmospheric Administration. On a recent day temperatures climbed to 35 degrees below zero Fahrenheit at the South Pole, Klein’s home for the next year.

“It’s been a big dream of mine to visit Antarctica,” said Klein in an interview before he left the U.S. “I feel very fortunate to have the opportunity.”

Shale oil fracking, conventional crude drilling produce similar greenhouse gas emissions

By Kat Kerlin

It requires roughly the same level of greenhouse gas emissions to extract shale oil as it does to extract conventional crude oil, according to a pair of studies by UC Davis and Stanford University released this week by the U.S. Department of Energy’s Argonne National Laboratory.

The research analyzed the Eagle Ford shale play in Texas and the Bakken play in North Dakota. These plays are shale formations with low permeability that must be hydraulically fractured to produce oil and gas.

The Eagle Ford Shale in Texas is one of the largest oil and gas producing regions in the country.

Grant for natural hazards research at UC Davis centrifuge

The National Science Foundation will award almost $5 million over five years to UC Davis to include the large earthquake-simulating centrifuge at the Center for Geotechnical Modeling as part of the new Natural Hazards Engineering Research Infrastructure program.

The geotechnical centrifuge at UC Davis is the largest of its kind in the world. It is used for scale model experiments of the effect of earthquakes on soils and buildings.

Oxygen oasis in Antarctic lake reflects distant past

At the bottom of a frigid Antarctic lake, a thin layer of green slime is generating a little oasis of oxygen, a team including UC Davis researchers has found. It’s the first modern replica discovered of conditions on Earth two and a half billion years ago, before oxygen became common in the atmosphere. The discovery is reported in a paper in the journal Geology.

The switch from a planet with very little available oxygen to one with an atmosphere much like today’s was one of the major events in Earth’s history, and it was all because some bacteria evolved the ability to photosynthesize. By about 2.4 billion years ago, geochemical records show that oxygen was present all the way to the upper atmosphere, as ozone.

UC Davis solution for better nitrogen climate modeling adopted by IPCC

By Kat Kerlin

Lawrence Berkeley National Laboratory researchers who provide global climate models to the Intergovernmental Panel on Climate Change have publicly thanked UC Davis associate professor Ben Houlton and his colleagues for creating a new solution to more accurately forecast nitrogen’s effects on global warming.

In an opinion piece in Nature Climate Change, the authors discuss how they have modified their model equations so that they now provide realistic predictions  anchored in Houlton’s benchmarking technique, published in that journal in April.

Bio-shock resistant: New center to apply biology to earthquakes, civil engineering

Taking lessons from nature and biology into civil engineering is the goal of the new Center for Bio-inspired and Bio-mediated Geotechnics, including the University of California, Davis, Arizona State University, New Mexico State University and the Georgia Institute of Technology, and funded with a five-year, $18.5 million grant from the National Science Foundation.

The center’s director will be Edward Kavazanjian, a professor of civil engineering and senior scientist at ASU’s Julie Ann Wrigley Global Institute of Sustainability. The UC Davis team will be headed by Jason DeJong, professor of geotechnical engineering in the Department of Civil and Environmental Engineering.

Changing ocean affecting salmon biodiversity and survival

What happens at the Equator, doesn’t stay at the Equator. El Niño-associated changes in the ocean may be putting the biodiversity of two Northern Pacific salmon species risk, according to a UC Davis study.

Researchers tracked the survival of Chinook and coho salmon from hatcheries in North America between 1980 and 2006.

Before the 1990s, ocean survival rates of Chinook and coho salmon varied separately from each other. However, the researchers were surprised to find that survival rates of the two species have since become increasingly similar.
