Soil hydraulic property data from the Climoor fieldsite in the Clocaenog Forest (2010-2012)

This dataset contains soil hydraulic measurement data from the Climoor field site in the Clocaenog forest, in North Wales. The collection contains five data sets. 1) soil bulk density (0-5 centimetre) and saturated water content. 2) Unsaturated hydraulic conductivity measured in the field at tensions of -2 and -6 centimetre using a mini disk infiltrometer. 3) Unsaturated hydraulic conductivity measured using a HYPROP (registered trademark) instrument, an instrument which determines the hydraulic properties of soil samples, on soil cores taken from the field plots. 4) Soil water release curves for wet soil corresponding to the hydraulic conductivity measurements made using a HYPROP in the laboratory on cores from the field. 5) Soil water release curve data for dry soil measured using a WP4 potentiometer. The dataset has been quality checked, and incorrect or missing values removed, data has not been infilled and not available (NA's) have been added where there is no data. Data was collected between the end of 2010 and early 2012. Data sets 1, 3 and 4 were collected in April and September, 2011, data set 2 in May, 2012 and data set 5 in November, 2010. The Climoor field experiment intends to answer questions regarding the effects of warming and drought on ecosystem processes. The reported data were collected to monitor site specific soil properties at a specific reference time.

Provenance & quality

Data was collected by experienced staff scientists who work with soils. Data sets 1, 3 and 4 were collected using stainless steel cores that fit to the HYPROP (registered trademark) instrumentation (UMS, Munich, Germany). Bulk density in data set 1 used the oven drying method at 105 degrees celsius. Data set 2 was collected using a minidisk infiltrometer (Decagon devices, Pullman, USA) while data set 5 was measured using a WP4-PotentiaMeter (Decagon devices, Pullman, USA). All data visually inspected using basic graphing tools as part of the quality assurance, quality control procedures. Data processing steps using the HYPROP data (3, 4) included using the HYPROP-FIT Software. In order to have water release curve data at the same suction, all raw data were interpolated using spline fitting in R (R Development Core Team, 2014). The minidisk infiltrometer measurements were converted to hydraulic conductivity using the standard approach detailed in the minidisk manual, which along with all the other manuals is included in the data set supporting materials. All data were collated into an Excel spreadsheet. Each dataset was exported from the Excel spreadsheet as a separate comma separated (.csv) file for ingestion into the Environmental Information Data Centre.
