Tied to the DOE-funded project led by Drs. Reed Maxwell and Dave Gochis (“Diagnosing dominant controls on carbon exchanges in high altitude, western U.S. headwaters”), the long-awaited flux tower was installed at the Pumphouse floodplain intensive study site on April 13, 2017.

Sampling during peak SWE (Snow Water Equivalent) conditions

On April 2-3, 2017, SFA team members dug snow pits to collect vertically-resolved measurements of snow density and samples for geochemical analysis.  Snow depths were ~50% greater than in 2016 at the same time of year.

Jill Banfield named 2017 Goldschmidt Medalist

Reposted from the Berkeley Lab EESA blog

Jill Banfield, Faculty Scientist in Earth & Environmental Sciences at LBNL, Professor at UC Berkeley, and member of the SFA team, has been named 2017’s recipient of the V.M. Goldschmidt Award. This award recognizes major achievements in geochemistry or cosmochemistry. Her work focuses on geomicrobiology—natural microbial communities in the terrestrial subsurface, sediments, water, biofilms and animals. She also studies nanoparticle formation and behavior in the natural environment.

Jill will receive her award at the Goldschmidt 2017 conference in Paris, France, this August.

Watershed Function SFA Research in Discover’s Top 100 of 2016

Discover-magazine-cover

Cover for Discover Magazine’s “Top 100 Stories of 2016”

Watershed Function SFA research—leading to the discovery of previously unknown species throughout the bacterial branches of the Tree of Life—was included in Discover Magazine’s “Top 100 Stories of 2016“, at #97 in the list.

The accolade accentuates the abundant media coverage the research garnered in April 2016 when it was first published. In fact, the article’s Altmetric score earned it spot #79 in Altmetric’s “Top 100 Articles of 2016“.

Stelzer Embarks on “Homeward Bound” Journey to Antarctica

Times in Greenland and AntarcticaThis week, Heidi Steltzer will embark on an Antarctic voyage as one of the first participants of “Homeward Bound“, a strategic and science initiative for women.  Read her blog post here.

Watershed Function SFA Featured in Crested Butte Magazine

Crested Butte 2016/17 coverThe semiannual magazine—popular with both locals and out of town guests—featured a short story about Watershed Function SFA research activities.

Find the article on page 18 (digital page 20) of the Winter 2016/17 edition on the Crested Butte Magazine Website. Or go here for a direct link to the story.

Facebook Page “mountaindaughters” highlights Heidi Steltzer’s Homeward Bound experience

Two CESD Directors Visit East River

Dr. Gary Geernaert (Director of Climate & Environmental Sciences Division, DOE-BER) and Dr. Bill Collins (Director of Climate & Ecosystem Sciences Division, Berkeley Lab) joined Dr. Kenneth H. Williams for a tour of Berkeley Lab’s Watershed Function Science Focus Area (SFA) East River field site near Crested Butte, Colorado on July 28-29, 2016.

The tour gave both directors an opportunity 1) to assess the growing DOE and EESA research footprint at the field site, including visits to both active and planned SFA study plots; 2) to assess available infrastructure, including that supported by the Rocky Mountain Biological Laboratory; and 3) to meet local stakeholders in the areas of water availability and water quality. Also joining the tour were Dr. Reed Maxwell (Colorado School of Mines) and Dr. Lindsay Bearup (Berkeley Lab) who described hydrological modeling activities ongoing at the field site and their relevance to broader DOE and Berkeley Lab mission areas in hydroclimate research.

SFA Team Members Get UAS-Certified

Six LBL researchers—including 4 Watershed Function SFA team members—traveled to Idaho National Laboratory (INL) to take an Unmanned Aircraft System (UAS) training.

The training course included a classroom briefing and hands-on pilot experience. Course instructor Matt Balderree offered thorough responses to attendee questions, and encouraged teamwork among participants—something which is crucial while conducting UAS operations in the field for reasons of safety, mitigating damage to equipment, and ensuring accurate collection of data.

The final test for pilot proficiency involved doing 2 figure 8’s around two pylons within a virtual rectangular box (10 x 40 meters). The test had to be completed within 2 minutes while maintaining heading in direction of travel.

Congratulations to Sebastien Biraud, Stephen Chan, Baptiste Dafflon, Emmanuel Leger, John Peterson, Craig Ulrich on successfully achieving pilot proficiency! Phil Long, also in attendance, was trained as a UAS observer.
