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. This data package also contains reflectance measurements of biocrust, soil, and granite samples acquired in a laboratory using a hyperspectral spectrometer. Included are hyperspectral reflectance measurements of a laboratory study using a variety of mixtures of soil and biocrust (0 – 100% biocrust), as well as reflectance measurements of individual grab samples collected from each of the field plots. These data aid our understanding of the ecological structure and functioning of biocrust ...
