Airborne Campaign in the Icy Arctic1 min read

Gulfstream-159 (G-1) research plane from the ARM Aerial Facility – in flight.

In the News: Sébastien Biraud led an ARM-ACME V team through a 16-week airborne campaign to collect data over the tundra of Alaska’s North Slope. The team flew 38 flights, just 500 feet above ground, from June 1 to September 15, using a Gulfstream-159 (G-1) research aircraft from the ARM Aerial Facility. Most flights went over Oliktok Point, Barrow, Atqasuk, Ivotuk, and Toolik Lake. The data collected from the flights over Oliktok Point and Barrow will be compared to data collected by ARM ground sites there. See ARM website and DOE’s Science Headlines.

Members of the ARM-ACME V team are Michael Hubbell (pilot), Jonathan Ray (pilot), Mike Crocker (mechanic)
Jason Tomlinson (flight engineer), Dan Nelson (Technician), Beat Schmid (AAF Director), Victor Morris (Technician), and Mikhail Pekour (flight engineer).

Flight crew members (from left to right): Clayton Eveland (pilot), John Hubbe (flight Engineer), Allen Cordle (pilot), Sebastien Biraud (scientist/PI), and Albert Mendoza (flight Engineer)

“Given the usual challenging weather in the North Slope, and there being snow in August, this is the best and most complete data set I’ve ever collected,” said Biraud. “Because we flew so often over a longer period of time, about every four days over three months, we were able to see changes at synoptic and seasonal scales. As a surprise, we still observed methane concentration enhancements, even though the snow covering the ground acted as a lid would on a bottle.”

Gathering and assessing these data will lead to improved current climate models, which now underestimate how rapidly the arctic is warming.

Study Sheds Light on Microbial Communities in Earth’s Subsurface2 min read

August 16, 2023

  From the tops of tree canopies to the bottom of groundwater reservoirs, a vast amount of living organisms interact with nonliving components such as rock, water, and soil to shape this area of Earth known as the “critical zone.” Over half of Earth’s microbes are located in the subsurface critical zone, which ranges from…

Carl Steefel Honored in Goldschmidt Session on Reactive Transport2 min read

August 2, 2023

The contributions of Carl Steefel to the reactive transport modeling scientific community were recognized in a session held in his honor at the recent Goldschmidt 2023 conference (Lyon, France). Goldschmidt is the foremost annual, international conference on geochemistry and related subjects, organized by the European Association of Geochemistry and the Geochemical Society. The session was…

DOE Funds Projects to Advance Forest Carbon Dioxide Removal Efforts and Agricultural Soil Carbon Conservation4 min read

August 1, 2023

The DOE Office of Fossil Energy and Carbon Management (FECM) and Office of Technology Transitions (OTT) recently announced $5 million in funding for four projects–two from Berkeley Lab with EESA leadership. The projects selected offer “promising solutions” to the nation’s climate change challenges by helping to reduce greenhouse gas emissions and will “accelerate their deployment…

Quantifying the strength of the land carbon sink3 min read

July 26, 2023

This article first appeared at nature.berkeley.edu/news. The world’s forests, grasslands, and other terrestrial ecosystems have played a substantial role in offsetting human carbon emissions—a capability that UC Berkeley researchers say would be threatened by continued global change. The assessment, published today as a new review paper in Nature Reviews Earth & Environment, presents a comprehensive analysis of…
