Surface abrasion and crust evolution following vegetation removal at the Jornada Basin LTER Scrape Site, 1995 to 2019

This data package contains measurements of soil surface abrasion and
the evolution of soil crust shear strength following a soil and
vegetation removal (scrape) treatment at the Jornada Basin LTER site
in southern New Mexico, USA. Soil erosion and soil crust shear
strength is measured at 3 locations along the prevailing wind
direction across a site initially scraped in 1995 to remove the A soil
horizon in a 100 meter radius semicircle. There are three monitoring
stations (East, Middle, West) on the Scrape Site. The West site is the
windward site, the East site is the leeward site, and the middle site
is halfway between the other two. At each location, measurements are
taken of the distance of the sand surface and soil crust to a crossbar
set into the soil. Three "Torvane" measurements that measure
the torque (shear strength) needed to break the crust are also made at
each location. These measurements were made monthly until 2014, and
are made annually since 2015. The Scrape Site has now become the
location for the GROWES study (JRN study IDs 511 and 523). Data
collection for this study is ongoing.
