Clay Barriers Restrict Ionic Transport

Carl Steefel and Ian Bourg (and others) proved, for the first time, that anions can be completely excluded from the smallest pores within a compacted illitic clay material, indicating the effectiveness of clay-based barriers for waste containment.

The Microbiome of Leaf-Nosed Bats

ESD ecologist Neslihan Taş was one of the leading authors of a recently published paper studying the relationship between different leaf-nosed bat feeding strategies and host microbiome composition.

Bacteria as Biosensors of Environmental Damage

Eric Dubinsky was part of a team whose work, reported on in mBio (the online journal of the American Society for Microbiology), has shown the power of microbial communities to predict sources of contamination in the environment.

Radiative Forcing, Albedo in Land-Use Scenarios

ESD’s Andy Jones and Bill Collins recently demonstrated the effectiveness of a new method for quantifying radiative forcing from land-use and land-cover change (LULCC) within the integrated Global Change Assessment Model (GCAM).

MnO2 Nanosheets Need Only Water, Sunlight To React

A team of scientists (including ESD Geochemistry Department Head Ben Gilbert) recently investigated the photoreduction of manganese (a key element in environmental processes) and quantified the yield and timescales of Mn(III) production.

Good IDEAS on Virtual Terrestrial Ecosystems

ESD’s Carl Steefel, Eoin Brodie, and Charlie Koven, among others, collectively sought ways of applying new scientific computing capabilities to studies of Earth’s subsurface. One of the results was IDEAS.

Simulating the Impact of Shale Gas on Groundwater

A team of ESD scientists used numerical simulation to investigate potential gas and water transport between a tight-gas reservoir and an overlying fresh-water aquifer following hydraulic fracturing operations.

Holm Paper Receives DOE Recognition

ESD’s Jennifer Holm and others recently published a paper (in Biogeosciences) that was noted in a post this week (March 25) on the home page of the DOE Office of Science website.

Magnitude of Permafrost Carbon−Climate Feedback

ESD climate scientists Charlie Koven and Bill Riley have recently developed the mechanistic basis for permafrost carbon-climate feedback within a land surface model, CLM4.5, the terrestrial component of the CESM Earth system model.
