Sentence examples for depth of active from inspiring English sources

In particular, in the case of almost dry soil, the penetration depth of active systems like GPS or a SAR was found to be around 10 cm [30] or 7 cm [31] respectively.

Then he would take out a metal probe shaped like a "T" and poke it into the ground at regular intervals, measuring the depth of the active layer.

Eventually, he explained, the heat that had gone into increasing the depth of the active layer would work its way downward, bringing the permafrost that much closer to the thawing point.

We have observed significant changes in the Earth's climate system including reduced snowfall in the Northern Hemisphere, retreat of sea ice in the Arctic, retreating glaciers on all continents, and shrinking of the area covered by permafrost and the increasing depth of its active layer.

The maximum depth of the active layer in September is ~ 40 cm.

The depth of the active layer, selected as h* = 0.3 cm, is the single adjustable parameter in the model.

The model results reveal that the maximum thawing depth of the active layer in summer gradually decreases along with the increase of the soil organic layer depth.

The resistivity data supported evaluation of the presence/absence of permafrost; location and depth of the active and intermediate layers; and in some conditions changes in ice content.

This increases the thaw depth of the active layer and lengthens the freezing/thawing cycle, which adversely affects the foundation stability and safety.

Properties of the fabricated planar waveguides were characterized by scanning electron microscopy (SEM) in order to gain information about chemical composition of the active layer prepared in Er3+/Yb3+ substrate and dark mode spectroscopy at 671 nm to obtain information about the optical properties (e.g. number of guided modes, refractive index profiles and depth of waveguide active layer).

In areas on the North Slope of Alaska where topography strongly controlled the flow and redistribution of surface water, NDVI change was found to be strongly related to the variability in the depth of the active (thawed) soil layers of tundra [16].
