McMurdo Dry Valleys LTER: Hyporheic sediment characteristics from transects across Von Guerard Stream, Taylor Valley, Antarctica, January 2019
In this data package, we present chlorophyll concentrations, percent loss-on-ignition organic matter, sorbed ammonium concentrations, and percent biogenic silica for hyporheic sediments collected in January 2019 from nine transects across Von Guerard Stream, Taylor Valley, Antarctica. These samples...
