Remote sensing approaches for degraded soil monitoring
La degradación del suelo compromete funciones ecosistémicas esenciales, lo que hace necesaria la implementación de métodos eficaces de monitoreo. Esta tesis doctoral investiga enfoques de teledetección pasiva para caracterizar y monitorizar suelos degradados en diversos contextos. El objetivo …

SOIL ORGANIC CARBON IN MID-ATLANTIC REGION FOREST SOILS: STOCKS AND VERTICAL DISTRIBUTION
Soil contains the largest terrestrial pool of organic carbon (Boschi et al., 2018) and temperate forest soils have been a major sink for atmospheric carbon; however, determining the size of the soil organic carbon stock can be problematic. Sampling practices vary for sampling depth, and determining …

Mercury emissions from crematoria
… that concentrations of mercury in crematoria soils might be significantly higher than controls. The source of the contamination has been assumed to be dental amalgam from cremated cadavers. Amalgam fillings contain 50% mercury, which under cremation conditions is totally vaporised and emitted …

Methods for detailed study of detergent action in cleaning food soils
… the cleaning of a baked heterogeneous food soil from stainless steel substrates was studied using a combination of fluid dynamic gauging, real-time imaging, millimanipulation, and solution analysis techniques. The extent of swelling, which is known to affect cleaning, was determined in situ …

Response of Pinyon-juniper woodlands to fire, chaining, and hand thinning
… We established a total of 73 vegetation and soil monitoring plots (38 treated, 35 adjacent untreated) across six Pinyon-juniper removal projects in Central and Eastern Nevada to look at the effects of fire, hand thinning, and chaining. The four burns examined together in Chapter 1 had similar …

Acid deposition effects on soil chemistry and forest growth on the Monongahela National Forest
… impact forest ecosystems. AD may acidify soils through base cation leaching or Al mobilization, may cause accumulation of nitrates and sulfates in soils, and in some cases has been related to forest decline. The Monongahela National Forest (MNF) lies downwind from many sources of AD …
