- Title
Element and Sediment Accumulation Rates in the Florida Everglades.

- Abstract
Sediment and element accumulation rates were determined in cores taken from two borrow canals and a rockpit lake of known age in the Florida Everglades. Bulk accumulation of ∼1 kg m-2 yr-1 is dominated by precipitated carbonate and lesser amounts of organic material. Acid-insoluble clastic input is 0.5–2% of the total accumulation except in a borrow canal close to a levee. The accumulation rate of Ca tracks bulk accumulation of carbonate while Al and Fe track bulk accumulation of fines. Trace elements Cu, Hg, Mn, and V accumulated at rates 2 to 10 times greater than published airborne fluxes while Ni and Zn accumulation rates were similar to airborne fluxes.
