Sampling was conducted quarterly from a Panicum hemitomon freshwater marsh, a Spartina patens brackish marsh, and a Spartina alterniflora salt marsh in Barataria Basin, Louisiana. Soil samples were fractionated into acid-volatile sulfides (AVS), elemental sulfur, HCl-soluble sulfur, pyrite sulfur, ester-sulfate sulfur, carbon-bonded sulfur, and total sulfur. Seasonal changes showed a greater effect on the distribution of S fractions in brackish and salt marsh than in the freshwater marsh. Season appeared to have a pronounced effect on the distribution of acid-volatile sulfides, elemental sulfur, and pyrite sulfur. The profile distribution of acid-volatile sulfides and elemental sulfur in all marshes was similar. These sulfur forms showed the greatest abundance in the oxidized zone (<20 ...
