Presentation Transcript

  1. Inorganic Carbon

  2. Inorganic Carbon Pools in Aquatic Systems

  3. H20 + CO2 <---->  (H2CO3)  <---->   HCO3-1 + H+   <---->   CO3-2  + H+free CO2 carbonic acid bicarbonate  carbonate

  4. Hardness and Alkalinity

  5. Inorganic Carbon and Buffering

  6. Low pH Waters

  7. Travertine and High pH Waters

  8. DIC in Rivers • Decomposition dominates over photosynthesis, so tend to produce CO2 rather than consuming • - Respiration can be so high that CO2 is maintained above equilibrium • Inflowing water high in CO2 from bacterial respiration • High turbulence causes CO2 to be lost quickly, but can see high CO2 in non-turbulent areas and during low flows • Rivers and streams also act to move alkalinity (i.e., HCO3- and CO32-) to lakes or to the ocean

  9. Inorganic Carbon Flux

  10. Export of Alkalinity by the Mississippi River

  11. DIC in headwater streams of different parent rock types (Shin et al. 2011)

  12. Lake Nyos Before and After an Outgassing Event

  13. Silent Death

  14. A Solution

  15. Standard Curve
