ESD “Detectives” Probe Mysterious Microbes

ESD’s scientists Hoi-Ying Holman, Gary Andersen, and Susan Hubbard are all prominently featured in a recent LBNL news release on unusual bacteria and their impact on the 2010 Gulf Oil Spill (and bioremediation in general).

Call for Proposals for FY2014 LDRDs

Director Alivisatos recently issued the call for proposals for the FY2014 Laboratory Directed Research and Development (LDRD) Program. All scientific staff from our Division are encouraged to think of potential innovative proposal topics.

Earth Scientists Talk Microbes and EBI

ESD’s Susan Hubbard, John Coates, and Gary Andersen talk about the role of microbes in our energy future and the role of the Energy Biosciences Institute (EBI) in a pair of short videos posted by the Medill News Service.

ESD at AGU: A Zone of Constant Activity

The AGU Fall Meeting in San Francisco last month (December 2012) was a great success, especially for LBNL’s Earth Sciences Division and our homebase at the site, the ESD booth—a zone of constant activity.

ESD Dives into Permafrost Soil

ESD scientists led by Susan Hubbard are exploring the little-known world of permafrost soils, which store almost as much carbon as the rest of the world’s soils and about twice as much as is in the atmosphere.

Remote monitoring of freeze-thaw conditions in Arctic soils using the complex resistivity method

ESD’s Yuxin Wu recently led a scientific team (including ESD’s Susan Hubbard) in conducting laboratory column experiments to explore the potential of the “complex resistivity” method for monitoring the freeze-thaw transitions of Arctic permafrost soils.

Iron-reducing bacteria accumulate ferric oxyhydroxide nanoparticle aggregates that may support planktonic growth

A team of scientists (including ESD’s Sirine Fakra, Roseann Csencsits, Kelly Wrighton, Ken Williams, and Jill Banfield) recently characterized planktonic microbial communities sampled from an aquifer in Rifle, Colorado, USA, close to the peak of iron reduction following in situ acetate amendment.

Visual Data Analysis and Exploration as an Integral Part of Environmental Management

Geologists, hydrologists, physicists and computer scientists are working together to create models of existing nuclear waste sites, to simulate their behavior, and to extrapolate it into the future.

Timing the Onset of Sulfate Reduction over Multiple Subsurface Acetate Amendments by Measurement and Modeling of Sulfur Isotope Fractionation

A team of ESD scientists headed by Jennifer Druhan has developed a biogeochemical reactive transport model that explicitly incorporates the stable isotopes of sulfur to simulate fractionation at the Rifle IFRC site during the 2007–2008 period.
