Abstract
Primary production and decompositional processes were measured within the mixing gradient of lagoonal and coastal water of the Pomeranian Bight during summer/autumn on four cruises between 1993 and 1995. Although different sampling strategies were applied, the results fitted well in a general pattern. Nearly all measured variables (e.g. POC, chlorophyll α) appear to be conservatively mixed along the salinity gradient between 2 and 8 PSU which is typical for the southern Baltic area. That pattern is, however, not due to a conservative behaviour of the components but to a balanced state of auto- and heterotrophic processes with a continuous, closely coupled recycling of matter. This is particularly evident in periods of nutrient limitation. Within the mixing gradient, changes were restricted to structural components (species composition) whereas the functional equilibrium was maintained.
