Organic Sediment Accumulation Within Spring Runs Associated with the St. Johns, Santa Fe, and Suwannee Rivers
Organic-rich sediments associated with 15 Florida springs and spring runs along the St. Johns, Santa Fe, and Suwannee rivers were probed, cored, and radiocarbon dated. Many of these spring runs have been accumulating sediments for thousands of years and may offer opportunities for archaeological study. Further detailed core work has been conducted at Wekiwa Spring, just downstream of the headspring vent, where ~3m of continuous, organic-rich sediment was collected. Multiproxy data from that core records the Pleistocene to Holocene transition and provides a record of changing sediment grain size, organic matter content, as well as carbon and nitrogen stable isotope composition.
