| Résumé : | Analysis of 3-m sediment cores revealed that profiles of carbon (C), sulfur (S), and iron (Fe) varied with relative distance from marine and terrestrial sediment sources in Tomales Bay, California. Despite relatively high sedimentation rates throughout the bay (historically 3-30 mm yr(-1)), sulfate reduction of deposited organic matter led to free-sulfide accumulation in sediments only at the location farthest from terrestrial runoff, the source of reactive iron Acid-volatile sulfide concentrations in all sediments ( |
