Alaskan studies indicate that these changes are already influencing ecosystem function and carbon balance in northern ecosystems (Grulke et al. 1990; Ochel and Billings 1992; Oechel et al. 1993; qtd. in Oechel et al. 1995).
Arctic and Alpine Soils Proposal (Ant)arctic (high-latitude) and alpine (mountain) areas are affected by relatively similar climates, as latitude and altitude produce similar meteorologic effects. In these geographic regions where temperature is at such a pronounced extreme, climate would seem to be the leading factor of soil development. It is my goal in this research paper to answer the following question: How do the soils of arctic and alpine areas differ? This idea, taken largely from an abstract by Birkeland (1975), will be explored through the comparison of the soils of these two geographic regions, and an analysis of the soil development factors in those environments. Introduction Both high-latitude and high-altitude regions are subject to climates that are dominated by extreme cold for at least part of the year.

Optical remote sensing (RS) is used to provide an effective knowledge base for advanced agriculture research (Ambast et al., 2002). Visible - Near Infrared (NIR) wavelengths offers the ability to monitor landscape process that are controlled by several surface parameters (Jacob et al., 2002; Price, 1992). Most commonly a simple or normalized ratio between the visible red and the NIR spectral wavebands are used for vegetation indices (VI). Several vegetation indices have been developed using the linearity of the NIR versus red reflectance as an indication of the green biomass. Some of the more sophisticated indices attempt to neutralize the soil influence by using a parameter or curve for bare soils.
