Datasets produced by Multiscale Impacts of Cyanobacterial Crusts on Landscape Stability (2/2) (NERC grant NE/K011464/1)

Abstract

Data from laboratory experiments conducted as part of project NE/K011464/1 (associated with NE/K011626/1) Multiscale Impacts of Cyanobacterial Crusts on Landscape stability. Soils were collected from eastern Australia and transferred to a laboratory at Griffith University, Queensland for conduct of experiments. Soils were characterised before, during and after simulated rainfall to determine impact of rainfall on soil surface roughness and physical crusting. For two soils (#13 DL Clay_cyano; #14 DL sand_cyano) cyanobacterial crusts were grown on subsamples and these were used to compare the response of soils with, and without, cyanobacterial soil crusts to rainfall treatment. Rainfall intensity of 60 mm hr-1 was used and rainfall was applied for 2 minutes (achieving 2 mm application), 5 minutes (achieving 5 mm application), 2 minutes (achieving 2 mm application) at 24-hour intervals with soils dried at 35°C and 30% humidity between applications in a temperature/humidity-controlled room. Variables measured were soil texture, penetrometry, salinity, splash loss, infiltration, organic matter content, occurrence of ponding, three-dimensional topography. Details of rainfall simulator, growth of cyanobacteria (where soil #13 = Acbc, soil #14 = Bcbc) and all other methods can be found in Bullard et al. 2018, 2019.

Lineage

Rainfall was simulated using the Griffith University Mobile Rainfall Simulator, a portable oscillating spray-type rainfall simulator comprising a water tank with pump and 4 x Veejet 80100 nozzles at a height of 2.5 m. Detailed description in Bullard et al. 2018). Soil characteristics were measured before rainfall application and after each successive application (instrument details in data files). Soil surface topography was determined using a Micro-Epsilon ScanCONTROL 2900-100 laser profiler mounted on a computer-controlled,motor-driven traversing frame. Scanner height was 24 cm above the soil surface and used to scan an area of soil 100 x 100 mm at a horizontal and vertical resolution of 0.078 mm (78 µm).
