A Model View of the Marsh
This view of the salt marsh ecosystem is a model, poetic to be sure, but a model nonetheless. Indeed, it anticipates the view of the marsh as an ecosystem, a group of components in interaction. In this chapter we address the nature of this interaction between marsh and sea and sky—more prosaically, between the soil, the water, and the air. In particular, we show how a simulation model of the salt marsh began as a summary of existing knowledge, was used to suggest new avenues of profitable research, was revised as the research progressed, and, finaüy, was employed to formulate hypotheses explaining both the dynamics of the marsh and its interaction with the estuary and the nearshore ocean.
