Flux tower installation at Pumphouse floodplain site
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.
A video highlighting conditions at the Upper Subalpine site and the headwaters of Rock Creek at the time of sampling is linked below.
