Surface soils from 0-10 cm have been homogenized and analyzed from Sawgrass and mangrove sites and Florida Bay sites. Soils and sediments were analyzed for a suite of physical/chemical variables, including bulk density, organic matter content, extractable iron, AVS and CRS sulfur, and various forms of extractable phosphorus. These analyses are completed to document the differences in soil structure among transect sites, and to provide a baseline dataset against which long-term changes in the physical/chemical properties of the soils can be detected.

Sampling is done once a year in mid-August. Method Step Description Bulk density obtained as the dry weight of known sample volume of soil. %organic obtained as weight loss on ignition expressed as percentage of dry weight. Extractable phosphorus by sequential extraction was obtained by the following: PI (MgCl2 extraction--inorganic P only); PII (buffered dithionite extraction--inorganic P only); PIII (1N HCl extraction--inorganic P only); PIV (ashing/acid extraction). Total phosphorus obtained by 1N HCl extraction of ashed soil sample. Extractable iron obtained from ashed soil sample as the result of 18-hour extraction with 1N HCl, followed by ferrozine analysis. Acid volatile sulfide obtained by 1N HCl extraction of soil sample followed by reaction with Cline's reagent. Chromium-reducible sulfur obtained by concentrated HCl/chromous chloride extraction of soil sample followed by reaction with Cline's reagent. Total reduced sulfur calculated as the sum of acid-volatile plus chromium-reducible sulfur.

This dataset replaces five original files 1) LT_SS_Chambers_001; 2) LT_SS_Chambers_002; 3) LT_SS_Chambers_003; 4) LT_SS_Chambers_004 and 5) LT_SS_Chambers_005. In order to facilitate FCE data use, the files have been combined into one new PASTA ready file: LT_SS_Chambers_001. The FCE program is discontinuing its practice of versioning data as of March 2013.
