Carl Steefel Named 2019 American Geophysical Union Fellow2 min read

Awards Climate and Ecosystem Sciences Division Energy Geosciences Division

 

Carl Steefel, a senior scientist in the Earth & Environmental Sciences Area at Berkeley Lab, has been named by the American Geophysical Union (AGU) as a 2019 AGU Fellow.

Every year, the AGU Fellows program recognizes members who have made exceptional contributions to the Earth and Space sciences. Vetted by a committee of AGU Fellows, honorees represent no more than 0.1 percent of AGU’s 60,000 members.

“It is a great honor to be recognized by an organization that is so well-known within the professional Geosciences community across the world,” said Steefel. “I think that my research, which intersects the fields of geochemistry and hydrology, is a good example of the type of interdisciplinary environmental science research that AGU promotes.”

Steefel is a geochemist who develops and applies models for multicomponent reactive transport to topics including subsurface water-rock interaction, contaminant migration, chemical weathering, and biogeochemical cycling. He developed the first multicomponent, multi-dimensional code for simulating water-rock interaction in non-isothermal environments, and in more recent years has continued to be active in developing capabilities for modeling transport and electrostatic effects in clays, pore scale reactive transport, isotopic fractionation, reaction-induced porosity and permeability change in porous media, and watershed hydrological and biogeochemical function. 

“This honor is particularly timely,” said Steefel. “The study of reactive transport is at a crossroads given that many achievements have finally come to fruition, but a whole new set of challenges and opportunities lie ahead. It is an exciting time to be at Berkeley Lab where we have a chance to contribute to the future of multi-scale transport, coupled chemo-hydro-mechanical phenomena, and nanogeosciences.”

Reactive transport modeling plays important roles in many collaborative research projects at Berkeley Lab. In the area of fundamental geochemistry, where Steefel and co-workers are studying the emergent mechanical and transport properties of clay-rich materials, the modeling framework and perspective enables an ambitious long-term research effort to be planned, assists in identifying specific gaps in basic science knowledge, and ensures that breakthroughs in understanding translate to useful predictive models.

Steefel leads/co-leads a number of large Department of Energy projects focused on advancing new modeling capabilities and using the capabilities to understand complex hydro-biogeochemical processes. The ongoing projects include the Subsurface Exascale Project, the ExaSheds Project, the Watershed Function SFA, and Basic Energy Sciences projects.

He serves as a Specialty Editor for Frontiers in Water–Water and Critical Zone and is an Associate Editor of Geochimica et Cosmochimica Acta.

Steefel holds a Ph.D. in Geochemistry from Yale University, an M.S. in Geology from the University of Colorado-Boulder, and a B.A. in English Literature from Washington University in St. Louis. 

The 2019 AGU Fellows will be honored with a special awards presentation during the AGU’s annual fall meeting on December 11 in San Francisco.

EESA scientist co-authors new comprehensive guide on ways to remove CO2 from the atmosphere2 min read

January 18, 2021

Berkeley Lab researchers are working on ways to sequester more carbon in soil, including through agricultural practices. (Credit: Berkeley Lab) Scientists say that any serious plan to address climate change should include carbon dioxide removal (CDR) technologies and policies, which makes the newly launched CDR Primer an especially vital resource, says Berkeley Lab scientist Margaret Torn, one…

New EESA research explores impact of land-use policy on California’s terrestrial carbon and greenhouse gas budget3 min read

January 12, 2021

The 28 million acres of natural and working lands across California provide a unique opportunity to meet greenhouse gas emission reduction goals through various land-use strategies, such as expanding urban forest areas or restoring woodlands. However, the need to mitigate wildfire severity is also a critical priority for California, and one that can increase emissions…

Impacts of Climate Change on Our Water and Energy Systems: It’s Complicated5 min read

January 11, 2021

As the planet continues to warm, the twin challenges of diminishing water supply and growing energy demand are intensifying. But because water and energy are inextricably linked, as we try to adapt to one challenge – say, by getting more water via desalination or water recycling – we may be worsening the other challenge by…

New Study: Are Drylands Getting Drier?1 min read

January 5, 2021

EESA visiting postdoctoral fellow Sha Zhou led a recent study exploring why climate models do not project drylands will become substantially drier with climate change as scientists have long believed. A paper published yesterday in the journal Nature Climate Change, “Soil moisture-atmosphere feedbacks mitigate declining water availability in drylands,” describes the importance of long-term changes…
