2003), ECaV and ECaH values were standardised to a temperature of 25[degrees]C using the equation of Campbell et al.
where zl = ln(ECaV) + ln(ECaH), z2 = ln(ECaH) - ln(ECaV), variables (u, v) represent spatial coordinates of each survey site, and [epsilon] represents the residual component.
Maps of the EM survey were developed with ArcGIS 9.3 (ESR1 2009) by lognormal ordinary kriging of ECaH and ECaV values.
During the first EM38 survey in March 2009, ECa values were highest for both ECaV and ECaH components (Table 2).
ECaH values of surface layers were also highest in March 2009 (318mS/m), then decreased in October 2009 (202 mS/m) and increased to 219 dS/m in March and November 2010.
