Historic Palmer Drought Severity Index data sets and plots for Georgia Division 9 have been updated in the GCE Data Portal to cover the period of January 1895 to February 2021. These indices are useful for characterizing the timing and severity of drought events in the long-term climate record. The data were downloaded from NOAA and converted into tabular data sets with decoded state and date columns to simplify filtering, plotting and analysis. More information about these indices and data sets is available here. 03/02/2021 – Data Release

At the north end of Cabretta Island, Spartina alterniflora is re-invading the island and forming marsh again. Because there currently are scattered clones, it is easy to see dramatic variation in clonal morphology. Here you see one clone that is tall and very clumped, and another that is short and sparse. I've seen similar variation in a newly-forming Spartina marsh in China. You don't see the short forms in mature marshes because they are hidden (or outcompeted) by the tall ones. But what advantages allow them to persist in nature? There's a research opportunity here for an enterprising graduate student.

The GCE is participating in DRAGNet, a global, distributed experiment that crosses disturbance treatments with nutrient additions to see how ecosystems respond to severe disturbances. We're actually roto-tilling plots in the field three years in a row to implement the disturbance! The experiment fits in well with the GCE emphasis on studying disturbance over the current funding cycle.
