Lagoons and shallow bays as filters in the coastal ecosystem

Abstract

In this paper, we will first give some examples on the filter function of shallow bays, focusing on nitrogen (N), based on studies in some coastal bays in temperate areas in Scandinavia (west and east coast of Sweden) and on the east Coast of USA (Virginia). Secondly, we will present conceptual models on how eutrophication can be expected to change the filter function of shallow coastal bays.
