    Description / Table of Contents: Klappentext: Die Ostsee als eines der größten Brackwassermeere der Welt ist immer noch gefährdet, sie wird weiter durch Abwässer und Abfälle belastet, die Wasserdurchmischung ist begrenzt. Um dieses noch junge Meer als Lebensraum zu erhalten, ist eine umfassende Analyse und ein ständiges Überwachen der ozeanographischen und ökologischen Parameter dringend nötig. Renommierte Forscher der größten Ostseeinstitute beschreiben in dieser Meereskunde der Ostsee alle wesentlichen Aspekte, die das Ökosystem Ostsee ausmachen, wie Klima, Geologie, Physik, Chemie, Pflanzen, Tiere, industrielle Nutzung und Belastung sowie mögliche Schutzmaßnahmen. Auch der Ostseeliebhaber wird in diesem leichtverständlichen Buch mit den zahlreichen Abbildungen zu seinen Beobachtungen auf See und am Strand wertvolle Hintergrundinformationen finden.

    Notes: 3 , NOx, PO4) caused eutrophication and consequent oxygen depletion in coastal bottom waters as well as in the depths of the open sea. In the anoxic sediments, hydrogen sulfide can be produced by protein-decomposing and sulfate-reducing bacteria. The bottom fauna will be destroyed and only H2S tolerant microorganisms can survive. Originating from cellulose manufacturing and from paper mills, large amounts of poisonous chlorinated compounds contaminated the coastal waters of Sweden and Finland until the 1980s. Most of this material is still present in sediments of the central Baltic Sea and can be resuspended by near bottom currents. To reduce pollution and improve the situation in the Baltic Sea, the surrounding countries organized the Helsinki Convention, which came into force on 3.5.1980. The Helsinki Commission (HELCOM) founded in 1974 acts as coordinator and is responsible for the enforcement of the Baltic monitoring program and international research projects. The activities of HELCOM have led to the reduction of dangerous pollutants which in turn has caused the regeneration of flora and fauna in some areas. Further improvements can be expected.

    Description: Denitrification was investigated in the Baltic proper at two stations with different conditions in the deep water. The Gotland Deep was examined as an example of a basin with anoxic, H2S‐containing deep water and station T was taken as an example of low‐oxygen (〈0.2 ml liter−1), sulfide‐free deep water. Denitrification was measured by the acetylene blockage method; in addition, N2O reduction was followed in samples without acetylene. To shed light on the factors limiting denitrification, we compared in situ rates to denitrification after adding nitrate or electron donors. Denitrification was restricted to the layer of the oxic‐anoxic interface in the Gotland Deep and to the water layer near the sediment of station T. For both stations it could be shown that denitrification was not limited by nitrate availability. A lack of available organic C seemed to limit denitrification rates and growth of denitrifiers. As a result of C limitation in the water column, denitrification was restricted to energy‐rich interfaces. In the low‐oxygen water away from energy‐rich interfaces, the less C‐demanding nitrification‐denitrification coupling (NH4+ → N2O → N2) seemed to be favored. Denitrification in the water of the central Baltic seems to be subjected to strong variability due to changing C supply during the course of the year. However, limitation by C availability can be assumed for most of the year and should be taken into account in calculating the N budget of the Baltic.
