Abstract: | Summary Transport processes were studied in a gully between a saltmarsh and an estuary. After storm tides, ebb currents in the gully reached high values. It is concluded that particulate matter (both obganic and inorganic) are imported into the marsh. Coarse organic debris is exported during storm tides, but this amount is low when compared with the primary production on the marsh. Exports are shown for dissolved organic carbon, ammonia, phosphate and silica, while nitrate and possibly nitrite are imported. Therefore, it seems warranted to conclude that the organic matter producedin situ and imported is mineralized in the marsh. |
