    Description / Table of Contents: Die Meere bedecken fast drei Viertel der Erde. Mit ihren gewaltigen Wassermassen und Strömungen bestimmen sie in Wechselwirkung mit der Atmosphäre maßgeblich das Klima der Erde. Ohne die Meere wäre die Erdgeschichte ganz anders verlaufen. Die Meeresströmungen transportieren Wärme aus den tropischen in die kalten Regionen; die wirtschaftliche Entwicklung Mittel- und Nordeuropas ist dem Wärmetransport des Nordatlantischen Strömungssystemszu verdanken. Seit Beginn der Industrialisierung verändert der Menschdurch den Verbrauch fossiler Energieträger die chemische Zusammensetzung der Atmosphäre und verstärkt damit den natürlichen Treibhauseffekt, was zu einer Erwärmung der unteren Atmosphäre und der Erdoberfläche einschließlich des oberen Ozeans führt. Das bewirkt die Schrumpfung des Meereises, was eine Verstärkung der globalen Erderwärmung zur Folge hat, da sich die Albedo der Erde verringert. Auch die Gletscher schmelzen. Das Schmelzwasser und die thermische Ausdehnung des Meerwassers führen zum Meeresspiegelanstieg, der gefährliche Höhe erreichen wird, wenn wir das Klima nicht konsequent schützen. Fast ein Drittel der Weltbevölkerung lebt in Küstennähe und muss in der Zukunft weichen, wenn die Emission des Kohlendioxids nicht gemindert wird. Durch die Aufnahme des Kohlendioxids durch die Meere sinkt der pH-Wert des Meerwassers, was für viele Meeresorganismen - vor allem Kalk bildende Tiere - wie Korallen, Muscheln und viele Planktonalgen schädlich ist. Mit diesen und anderen Folgen für Pflanzen, Tiere und Menschen befassen sich rund 100 Fachleuten im vorliegenden Buch. Die Beiträge wurden leicht verständlich verfasst.

    Notes: Abstract The aim of the present study was to investigate whether bacterial mutagenicity assays can be applied in sediment quality assessment. The arabinose-sensitive forward mutation strain Salmonella typhimurium BA 9 was added to freshly deposited sediments of the River Elbe, collected during March, April, and May 1994. Up to twelve locations were sampled each month and mutagenicity was determined employing the solid phase and sequentially prepared toluene- and methanol-extracts of the sediments. Mutagenicity was detected at all sites within the solid sediments without addition of S9-mix; however, the addition of mammalian enzymes (S9) enhanced the mutagenic effect. In contrast, mutagenicity of toluene extracts containing the lipophilic fraction of the sediment samples was higher in the absence of S9-mix; peaks of mutagenic activity in these samples were observed at Dessau (mouth of the River Mulde) and close to the city of Hamburg (Bunthaus). Similar results were obtained with methanolic extracts of the sediments, although the effects were usually lower in comparison to the corresponding toluene extracts. These results show that the mutagenicity assays are capable of assessing water/sediment contamination and reveal that the mutagenicity detected in sediments reflects local industrial activities as well as hydrologic conditions.

    Description: The measurements were obtained during two North Sea wide STAR-shaped cruises during summer 1986 and winter 1987, which were performed to investigate the circulation induced transport and biologically induced pollutant transfer within the interdisciplinary research in the project "ZISCH - Zirkulation und Schadstoffumsatz in der Nordsee / Circulation and Contaminant Fluxes in the North Sea (1984-1989)". The inventory presents parameters measured on hydrodynamics, nutrient dynamics, ecosystem dynamics and pollutant dynamics in the pelagic and benthic realm. The research program had the objective of quantifying fluxes of major budgets, especially contaminants in the North Sea. In spring 1986, following the phytoplankton spring bloom, and in late winter 1987, at minimum primary production activity, the North Sea ecosystem was investigated on a station net covering the whole North Sea. The station net was shaped like a star. Sampling started in the centre, followed by the northwest section and moving counter clockwise around the North Sea following the residual currents. By this strategy, a time series was measured in the central North Sea and more synoptic data sets were obtained in the individual sections. Generally advection processes have to be considered when comparing the data from different stations. The entire sampling period lasted for more than six weeks in each cruise. Thus, a time-lag should be considered especially when comparing the data from the eastern and the western part of the central and northern North Sea, where samples were taken at the beginning and at the end of the campaign. The ZISCH investigations represented a qualitatively and quantitatively new approach to North Sea research in several respects. (1) The first simultaneous blanket coverage of all important biological, chemical and physical parameters in the entire North Sea ecosystem; (2) the first simultaneous measurements of major contaminants (metals and organohaline compounds) in the different ecosystem compartments; (3) simultaneous determinations of atmospheric inputs of momentum, energy and matter as important ecosystem boundary conditions; (4) performance of the complex measurement program during two seasons, namely the spring plankton bloom and the subsequent winter period of minimal biological activity; and (5) support of data analysis and interpretation by oceanographic and meteorological numerical models on the same scales.

    Description: After two companies were awarded a 30-year license for the exploration and exploitation of metalliferous sediments in the Atlantis II Deep (Red Sea) in 2011, we herewith present conclusions and recommendations derived from an environmental risk assessment, the Metalliferous Sediment Atlantis II Deep (MESEDA) study, conducted in the period 1977–1981. For economic reasons, this program was discontinued before final report delivery and fell dormant for 30 years. The effects of environmental disturbances of the benthic and the near-bottom water layer habitats in and around the mining site deserve further and more modern risk assessments. We examine the relevance of our 1981 recommendations and of subsequent publications to the extended period of resource extraction planned for this century and recommend more up-to-date risk assessment investigations and evaluations.
