Open WL Archief (OWA)

Over het archief

Het OWA, het open archief van het Waterbouwkundig Laboratorium heeft tot doel alle vrij toegankelijke onderzoeksresultaten van dit instituut in digitale vorm aan te bieden. Op die manier wil het de zichtbaarheid, verspreiding en gebruik van deze onderzoeksresultaten, alsook de wetenschappelijke communicatie maximaal bevorderen.

Dit archief wordt uitgebouwd en beheerd volgens de principes van de Open Access Movement, en het daaruit ontstane Open Archives Initiative.

Abstract

Eutrophication is the major threat for marine ecosystems in coastal and archipelago areas of the Baltic Sea. Eutrophication-induced effects on benthic macrofauna were studied over a 30 year period in the Åland Islands, northern Baltic Sea. This study describes the present soft-bottom community and analyses changes in community structure in definable archipelago zones, and relates them to environmental changes since the 1970s. Similar analyses are made for changes in the benthic communities in the transition zone between the outer archipelago and the open sea over the last decade. Abundance and biomass peaked in the late 1980s after which a general decrease has taken place, but in different ways in the various archipelago zones. This decline seems to be closely linked with local nutrient loads, rather than to the overall trends in the Baltic Sea. A new species in this low-diversity area is the polychaete Marenzelleria viridis, which since its first observation in 1993 has rapidly spread over the entire region and is now among the five most dominant species in the benthic assemblage.
