The hypothesis that estuarine systems produce more material (e.g. inorganic nutrients, particulate carbon, dissolved organic carbon) that can be utilized or degraded within, and that excess material is being exported to the coastal marine environment where it may contribute to coastal ocean productivity has received considerable attention during the past few years. This “outwelling” hypothesis of Odum (1980) was examined for estuarine, saltmarsh and mangrove swamp systems by, for example, Vallela et al. (1978), Nixon (1980), Black et al. (1981), Boto and Bunt (1981), Daly and Mathieson (1981), Chrzanowski et al. (1982, 1983), Wolaver et al. (1983), Woodroffe (1985), Dame et al. (1986) and Baird et al. (1987).
