Freshwater Outflow in Relation to Space and Time Dimensions of Complex Ecological Interactions in Coastal Waters

Part of the NATO ASI Series book series (volume 7)

Abstract

In marine ecosystems physical and geochemical water properties as well as biomass may be advected by currents over large distances. In addition, several species migrate and exchange biomass between distant biocenoses. Considering also the long generation times of species in temperate regions, and how this relates to transfer of energy in marine food webs, it must be acknowledged that time and space scales in marine ecosystems are very extensive. Ecological processes in temperate shelf waters support reproduction in many important stocks, and are influenced by freshwater outflow from land. However, the role of freshwater input to coastal ecosystems is inadequately understood, which is unfortunate, considering impacts of man’s regulation of river flow. To solve apparent conflicts and optimise the future use of coastal zones, new sets of adequate concepts and methods for assessing coastal marine ecosystems, are needed.
