Abstract
Sediment and element accumulationrates were determined in cores taken from two borrowcanals and a rockpit lake of known age in the FloridaEverglades. Bulk accumulation of ∼1 kg m-2 yr-1 is dominated by precipitatedcarbonate and lesser amounts of organic material. Acid-insoluble clastic input is 0.5–2% of the totalaccumulation except in a borrow canal close to alevee. The accumulation rate of Ca tracks bulkaccumulation of carbonate while Al and Fe track bulkaccumulation of fines. Trace elements Cu, Hg, Mn, andV accumulated at rates 2 to 10 times greater thanpublished airborne fluxes while Ni and Zn accumulationrates were similar to airborne fluxes.
