Application Of Biomarkers And Compound Specific Stable Isotopes For The Assessment Of Hydrology As A Driver Of Organic Matter Dynamics In The Everglades Ecosystem, Ding He
FIU Electronic Theses and Dissertations
The Everglades is a sub-tropical coastal wetland characterized among others by its hydrological features and deposits of peat. Formation and preservation of organic matter in soils and sediments in this wetland ecosystem is critical for its sustainability and hydrological processes are important divers in the origin, transport and fate of organic matter. With this in mind, organic matter dynamics in the greater Florida Everglades was studied though various organic geochemistry techniques, especially biomarkers, bulk and compound specific δ13C and δD isotope analysis. The main objectives were focused on how different hydrological regimes in this ecosystem control organic matter …
