Southern Fire Exchange
-
The Southern Fire Exchange (SFE) is a fire science delivery program in the Southeast, funded by the Joint Fire Science Program in agreement with the United States Forest Service, Southern Research Station. With our key partners, we strive to improve access to and usefulness of southern fire science information and offer opportunities for the fire community to interact and learn from one another.

Southern Ocean acidification: A tipping point at 450-ppm atmospheric CO2
-
Southern Ocean acidification via anthropogenic CO2 uptake is expected to be detrimental to multiple calcifying plankton species by lowering the concentration of carbonate ion (CO32) to levels where calcium carbonate (both aragonite and calcite) shells begin to dissolve. Natural seasonal variations in carbonate ion concentrations could either hasten or dampen the future onset of this undersaturation of calcium carbonate. We present a large-scale Southern Ocean observational analysis that examines the seasonal magnitude and variability of CO32 and pH. Our analysis shows an intense wintertime minimum in CO32 south of the Antarctic Polar Front and when combined with anthropogenic CO2 uptake is likely to induce aragonite undersaturation when atmospheric CO2 levels reach 450 ppm. Under the IPCC IS92a scenario, Southern Ocean wintertime aragonite undersaturation is projected to occur by the year 2030 and no later than 2038. Some prominent calcifying plankton, in particular the Pteropod species Limacina helicina, have important veliger larval development during winter and will have to experience detrimental carbonate conditions much earlier than previously thought, with possible deleterious flow-on impacts for the wider Southern Ocean marine ecosystem. Our results highlight the critical importance of understanding seasonal carbon dynamics within all calcifying marine ecosystems such as continental shelves and coral reefs, because natural variability may potentially hasten the onset of future ocean acidification.

Southern Salvelinus - Brook Trout Below the Mason-Dixon
-
Southern Appalachian Brook Trout are a geographically isolated strain of Brook Trout (Salvelinus fontinalis) that are facing a realistic possibility of disappearing. They are a valuable indicator species and the decline in brook trout populations is a reflection of the degradation of our beautiful streams. They are the only native trout (technically a char) to the Eastern United States. Because of the introduction of invasive Rainbow Trout (from the Western US) through state fish stocking programs, they are being out competed and brook trout populations are being even further reduced.
