Résumé :	Vertical distribution patterns of organic geochemical constituents and the enzymes aminopeptidase and beta-glucosidase provide insights about the nature and reactivity of sediment organic matter in the sandy sediments of two shallow "South Texas" estuaries. Sediment total organic carbon (TOC) delta C-13 values indicated that the organic matter (OM) was derived more from a mixture of seagrass and phytoplankton than from terrigenous OM. Down-core amounts of TOC and total nitrogen (TN) were
