Data from field experiments conducted as part of project NE/K011464/1 (associated with NE/K011626/1) Multiscale Impacts of Cyanobacterial Crusts on Landscape stability.

This dataset presents field measurements of the biological response of cyanobacterial soil crusts to rainfall and of the impact of this response on the susceptibility of the soil surface to wind erosion. The data are in Excel spreadsheets and record cyanobacteria fluorescence, the presence of chlorophyll a and exocellular polysaccharide, soil surface strength, particle size distribution and soil loss by wind erosion. The study was located within Diamantina National Park (23°36’44.8”S; 143°17’46.9”E) in the north-eastern part of the Lake Eyre basin, central Australia. Site characteristics are 1/A physical depositional crust; 2/B cyanobacterial crust on dune flank; 3/D cyanobacterial crust on claypan; 4/E physical structural crust; 5/C cyanobacterial crust on nebkha field. Different amounts of rainfall were applied using Griffith University Mobile Rainfall Simulator (see Bullard et al. 2018 for technical details). Following rainfall and drying in situ of the surface, wind erosion was measured using a portable mini-wind tunnel (see Strong et al. 2016 for technical details). The data will be of value for understanding cyanobacterial response to different rainfall amounts and wind speeds under future climate scenarios.

Statement
Sites with different types of cyanobacteria soil crusts were identified in central Australia. Rainfall was applied (5 mm and 10 mm) to each site using a rainfall simulator. Before and after rainfall crust characteristics were measured. After soils had dried, but within 48 hours of rainfall the susceptibility of the soils to wind erosion was measured using a micro-wind tunnel. Where appropriate raw data are supplied for user-analysis. For the wind tunnel runs data are processed to indicate soil loss per run and summarised in a spreadsheet as wind tunnel requires proprietary software.
