Marine Geochemistry
A summary of the latest research in this field. The topics comprise the sedimentological examination and physical properties of the sedimentary solid phase, pore water and pore water constituents, organic matter as the driving force of most microbiological processes, biotic and abiotic redox reactions, carbonates and stable isotopes as proxies for paleoclimate reconstruction, metal enrichments in ferromanganese nodules and crusts as well as in hot vents and cold seeps on the seafloor. The current model conceptions lead to the development of different types of computer models, allowing the global mass exchanges between oceans and sediments to be balanced.
Alfred Wegener
The book should be of interest not only to earth scientists, students of polar travel and exploration, and historians but to all readers who are fascinated by the great minds of science.--Henry R. Frankel, University of Missouri-Kansas City, author of The Continental Drift Controversy "Science & Education"
German Exploration of the Polar World
German Exploration of the Polar World is the exciting story of the generations of German polar explorers who braved the perils of the Arctic and Antarctic for themselves and their country. Such intrepid adventurers as Wilhelm Filchner, Erich von Drygalski, and Alfred Wegener are not as well known today as Robert Falcon Scott, Roald Amundsen, Ernest Shackleton, Robert E. Peary, or Richard E. Byrd, but their bravery and the hardships they faced were equal to those of the more famous polar explorers. In the half-century prior to World War II, the poles were the last blank spaces on the global map, and they exerted a tremendous pull on national imaginations. Under successive political regimes, t...
Marine Anthropogenic Litter
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 rece...
Faszination Meeresforschung
In diesem Buch berichten 95 Wissenschaftlerinnen und Wissenschaftler über ihre Forschung im Ozean und an den Küsten. Sie führen den Leser von den eisbedeckten Polarmeeren über die Nord- und Ostsee bis zu den Seegraswiesen, tropischen Mangroven und Korallenriffen. Die Beiträge veranschaulichen die Vielfalt der Lebensgemeinschaften zwischen Strand und Tiefsee. Das Größenspektrum der Organismen reicht von Walen und Fischen über Planktonkrebse und Muscheln bis zu Kieselalgen und Bakterien. Die globalen – vom Leben im Meer bestimmten – Stoffkreisläufe werden ebenso behandelt wie die molekularbiologischen Anpassungen der Mikroorganismen, und hier sind auch die größten methodischen F...

Land-Ocean Systems in the Siberian Arctic
The Arctic and its surrounding marginal seas are considered some of the most sensitive elements of the global environment, which may respond rapidly to climate change. However, due to various reasons, our knowledge of the processes which drive the Arctic system today and in the past is still relatively sparse. Based on a multidisciplinary approach, German and Russian scientists describe in this book the natural paleorecords and modern data which were collected over the past 6 years. These marine and terrestrial datasets provide important new insights into the causes, impacts, and feedback mechanisms of this extreme Arctic environment.
Arctic-Subarctic Ocean Fluxes
We are only now beginning to understand the climatic impact of the remarkable events that are now occurring in subarctic waters. Researchers, however, have yet to agree upon a predictive model that links change in our northern seas to climate. This volume brings together the body of evidence needed to develop climate models that quantify the ocean exchanges through subarctic seas, measure their variability, and gauge their impact on climate.
