Uncovering the Mechanistic Basis for Soil-Microbial-Community Response to Altered Precipitation Patterns

ESD’s Eoin Brodie and Nicholas Bouskill are using rainfall manipulation experiments to characterize the response of soil microbial communities to different rainfall patterns, and how this might affect the soil’s ability to sequester carbon.


Greengenes “Turns” A Million!

Greengenes is now one of the largest curated collections in the world and is being applied to a number of different scientific investigations, including biofuels, medicine and microbial diversity.

Resolving Clouds in Climate Change Models

Lauren Sommer of KQED's QUEST program sat down with ESD's Bill Collins to learn about how faster supercomputers will help scientists run climate simulations.


Achieving Carbon Sequestration and Geothermal Energy Production: A Win-Win!

An international scientific team, including ESD’s Barry Freifeld, was awarded $5M by DOE to combine CCS with geothermal energy extraction techniques in developing a new kind of turbine.


Simrank: A Rapid and Sensitive General-Purpose k-mer Search Tool

ESD's Todd DeSantis and his team recently developed Simrank, a general-purpose software tool that rapidly searches biological sequences extracted from biological specimens.


Nano-Foam Could Plug Underground CO2 leaks

Injecting nanoparticles into underground reservoirs before they are filled with CO2 could make any leaks self-sealing. ESD's Don Depaolo says the ideas is promising by may be prohibitively expensive.


ESD's Terry Hazen Wins PNNL's Outstanding Lecture Award

ESD's Terry Hazen won PNNL's "Outstanding Lecture" award after giving his talk "A Systems Biology Approach to the Deepwater Horizon Oil Spill – an Example of Team Science for Ecological Disasters.”


Developing estimation frameworks that integrate indirect and direct measurements during remediation

ESD's Susan Hubbard and colleagues recently conducted laboratory investigations, field and numerical studies to remotely quantify complex subsurface processes associated with environmental remediation.

SIP data reveals complexity of biogeochemical transformations during subsurface remediation

Sources: Susan Hubbard & Dan Hawkes Recent analysis and interpretation of field-scale SIP data are beginning to reveal the complexity of biogeochemical transformations that occur during remediation in heterogeneous subsurface environments. ESD’s Michael Commer and his geophysics imaging team (Commer et al. 2011) have developed a three-dimensional SIP inversion algorithm...

Lab studies quantify the geophysical response to the evolution of precipitates

Sources: Susan Hubbard & Dan Hawkes Laboratory experimental studies have been performed to quantify the geophysical response to the evolution of precipitates in porous media under controlled conditions. Monitoring the occurrence, spatial distribution, and temporal evolution of remediation- induced mineral precipitates in the subsurface is critical for evaluating the performance...
