The chemical composition of the surface and in-depth layers of each sample were examined by X-ray photoelectron spectroscopy and X-ray diffraction measurements.
It has also been fitted to the Kanto region in separate depth layers at M > 4.75 (Rhoades and Evison, 2006).
A consequence of these algorithms is that the whole depth map has been modified, which will severely blur the distance between scene objects in different depth layers.
Results illustrated that the contents of a given soil property in different depth layers were typically more correlated when only the long range components were compared.
They were used to produce fine spatial resolution continental maps of total P in six depth layers by combining the bootstrap, a decision tree with piecewise regression on environmental variables and geostatistical modelling of residuals.
The study was performed in Bom Jardim County, Brazil, and covered an area of 390 km2 with a soil database of 208 sample points distributed in six depth layers (0.53 pts/km2).
The SOC in soil depth layers of 0 10, 10 20, 20 40, 40 60 and 60 80 cm were reduced with afforestation of grassland but not significantly (p > 0.05), while conversion of cropland to forests (trees or shrubs) increased SOC significantly for each soil depth layer up to 60 cm depth (p < 0.05).
Figure 4 shows the mean circulation (speed, direction and stability) in the depth layers with maximum cod egg or larval abundance for May 1988.
In order to reduce cross talk between calcium signals originating from dendritic branches located in different depth layers of the tissue, we confined excitation to a single plane by using two-photon laser scanning microscopy (TPLSM).
Post-hoc analysis of this modeled data was then used to predict the relative sensitivity of photons emerging at different lateral distances from the incident beam to changes in absorption in each depth layer.
Besides the estimation of the SOC stock, the soil samples, taken in four different depth layers, were physically fractionated to characterize the quality of the SOC.
