    Description / Table of Contents: Verlagsbeschreibung: "This book describes how man-made litter, primarily plastic, has spread into the remotest parts of the oceans and covers all aspects of this pollution problem from the impacts on wildlife and human health to socio-economic and political issues. Marine litter is a prime threat to marine wildlife, habitats and food webs worldwide.The book illustrates how advanced technologies from deep-sea research, microbiology and mathematic modelling as well as classic beach litter counts by volunteers contributed to the broad awareness of marine litter as a problem of global significance. The authors summarise more than five decades of marine litter research, which receives growing attention after the recent discovery of great oceanic garbage patches and the ubiquity of microscopic plastic particles in marine organisms and habitats. In 16 chapters, authors from all over the world have created a universal view on the diverse field of marine litter pollution, the biological impacts, dedicated research activities, and the various national and international legislative efforts to combat this environmental problem. They recommend future research directions necessary for a comprehensive understanding of this environmental issue and the development of efficient management strategies. This book addresses scientists, and it provides a solid knowledge base for policy makers, NGOs, and the broader public."

Dabei werden ausgewählte, verschiedenartige Ökosysteme von Spitzbergen im Norden entlang des norwegischen Kontinentalrandes, über das Mittelmeer bis in das Schwarze Meer studiert. Der erste Arktisfahrtabschnitt der Polarsternʺ zu Beginn des IPY (International Polar Year) war in drei Unterabschnitte gegliedert, um so Untersuchungen an vier Ökosystemtypen entlang des nördlichen europäischen Kontinentalrandes durchzuführen. Ein besonderer Schwerpunkt lag dabei auf sogenannten hot spotsʺ, stark physikalisch kontrollierten Systemen, die zudem durch vergleichsweise dynamische geologische und/oder hydrologische Randbedingungen, wie zum Beispiel instabile Kontinentalhänge, Tiefseegräben, Tiefwasserkorallen, kalte Sickerstellen oder sauerstofffreie, von Bakterien besiedelten Lebensgemeinschaften geprägt sind...

    Description: Time-series studies of arctic marine ecosystems are rare. This is not surprising since polar regions arelargely only accessible by means of expensive modern infrastructure and instrumentation. In 1999, theAlfred Wegener Institute, Helmholtz-Centre for Polar and Marine Research (AWI) established the LTER(Long-Term Ecological Research) observatory HAUSGARTEN crossing the Fram Strait at about 79◦N.Multidisciplinary investigations covering all parts of the open-ocean ecosystem are carried out at a totalof 21 permanent sampling sites in water depths ranging between 250 and 5500 m. From the outset,repeated sampling in the water column and at the deep seafloor during regular expeditions in summermonths was complemented by continuous year-round sampling and sensing using autonomous instru-ments in anchored devices (i.e., moorings and free-falling systems). The central HAUSGARTEN stationat 2500 m water depth in the eastern Fram Strait serves as an experimental area for unique biologicalin situ experiments at the seafloor, simulating various scenarios in changing environmental settings.Long-term ecological research at the HAUSGARTEN observatory revealed a number of interesting tem-poral trends in numerous biological variables from the pelagic system to the deep seafloor. Contrary tocommon intuition, the entire ecosystem responded exceptionally fast to environmental changes in theupper water column. Major variations were associated with a Warm-Water-Anomaly evident in sur-face waters in eastern parts of the Fram Strait between 2005 and 2008. However, even after 15 years ofintense time-series work at HAUSGARTEN, we cannot yet predict with complete certainty whether thesetrends indicate lasting alterations due to anthropologically-induced global environmental changes of thesystem, or whether they reflect natural variability on multiyear time-scales, for example, in relation todecadal oscillatory atmospheric processes.
