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 were collected to address questions about the retention and processing of particulate organic matter in the hyporheic zone of McMurdo Dry Valley streams.
An important part of the McMurdo Long Term Ecological Research (LTER) project is monitoring of spatial and temporal patterns, and processes that control primary production in perennial ice-covered lakes. This data set addresses this core area of research and quantifies chlorophyll-a concentrations at specific depths in McMurdo Dry Valley lakes.
