In this data package, we present diatom community assemblages from hyporheic sediments collected in January 2019 from six 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. The six transects were located at pools, riffles, and meanders (three of each geomorphology type) along Von Guerard Stream and extended across the stream channel to the edges of the wetted zone, ranging from 6.6 to 13.6 m in length.

This data package includes ecological parameters of biocrust and soil from samples collected in-situ within the Lake Fryxell Basin of the McMurdo Dry Valleys, Antarctica during December of 2019. Parameters include biological (ash-free dry mass, pigment concentration, and counts of soil invertebrates), physical (water content, electrical conductivity, and pH), and chemical properties (inorganic nitrogen, inorganic phosphorous, total nitrogen, and total organic carbon) of the surface soil, biocrust, and underlying soil.
