Title: A Freshwater Perspective on Climate Variability and its Effect on Marine Ecosystems
Abstract: Abstract There are several points of departure when assessing the effects of climatic variations from a limnological perspective. First, to which extent do climatic effects on freshwaters per se impact marine ecosystems? Second, can the study of enclosed and comparatively simple ecosystems of lakes be used to gain insights in marine effects? And third, are there any pronounced and general differences in expected responses between limnetic and marine ecosystems? This chapter explores these subjects, focusing on the riverine efflux to marine areas. It is shown that climatic fluctuations indeed may influence marine ecosystems indirectly by way of freshwater systems. Processes related to weathering rate, temperature changes, and precipitation are key determinants of the fluxes of dissolved organic carbon and key nutrients to coastal marine regions, and thus play an important role in regulating productivity in the ecosystems of such areas.
