PPT-Soil and Permafrost

Ooooh Exciting Soil Soil is from parent rock It takes 200 years to form a layer of soil 1cm thick Soil forms distinct layers over time Layers can be distinguished by color texture and composition. They generally are less than 2 inches thick and are massive Crusts are created by the breakdown of structural units by flowing water or raindrops or through freezethaw action Soil crusts are generally only a temporary condition Typically the soil im Glacial and .

Dry, brown to reddish-brown with variable accumulations of clay, calcium and carbonate, and soluble salts. Water samples collected over six years from major Arctic rivers (. www.arcticgreatrivers.org. ) were analyzed using the MagLab’s record-setting 21T ultra-high-resolution Fourier-transform ion cyclotron resonance mass spectrometer. This magnet system’s resolving power is capable of determining elemental composition for tens of thousands of individual molecules in a single water sample. Combined with isotopic data, these formulae revealed both a common core amongst samples, as well as unique tracers of seasonality and a changing Arctic. .
