How acidic is the rain if atmospheric CO2 concentration doubles? part of Cutting Edge:Hydrogeology:Hydrogeology, Soils, Geochemistry 2013:Activities
Students use basic aqueous geochemistry knowledge to investigate controls of the atmospheric carbon dioxide level on pH values of the wet precipitation at standard conditions (25 oC, 1 atmospheric pressure).
How to read elemental soil profiles to investigate the biogeochemical processes in Critical Zone? part of Cutting Edge:Hydrogeology:Hydrogeology, Soils, Geochemistry 2013:Activities
In this exercise, students use elemental chemistry data in a soil profile to explore major biogeochemical processes that dominate in critical zone. Data will be provided, and students calculate and graph the mass transfer coefficients as a function of depth using Excel. Based on these plots, student make generalized statements about how different elements behave in this soil profile and what processes dominate, e.g., depletion by rock-water interaction, addition by dust inputs or elemental loading by human activities etc.
Soil properties, morphology and formation part of Cutting Edge:Hydrogeology:Hydrogeology, Soils, Geochemistry 2013:Courses
This course centers on the overlap of soil science and geology. Our goal is to explain the fundamental principles in soil sciences, introduce the concept of critical zone, where water, rock, biology, and atmosphere interact as a system.
