Book excerpt: Within the joint German-Russian research project Siberian River Run-off (SIRRO) multidisciplinary studies were carried out in the Ob and Yenisei estuaries and adjacent southern Kara Sea (Arctic Ocean). The overall goal of the project was to extend knowledge on understanding the freshwater and sediment input by the major Siberian rivers, and its impact on the environments of the inner Kara Sea. The main results of oceanographical, biological, geochemical, geological and modelling studies are presented in four main chapters.
Download or read book The Organic Carbon Cycle in the Arctic Ocean written by Rüdiger Stein and published by Springer Science & Business Media. This book was released on 2011-06-27 with total page 394 pages. Available in PDF, EPUB and Kindle. Book excerpt: The flux, preservation, and accumulation of organic carbon in marine systems are controlled by various mechanisms including primary p- duction of the surface water, supply of terrigenous organic matter from the surrounding continents, biogeochemical processes in the water column and at the seafloor, and sedimentation rate. For the world's oceans, phytoplankton productivity is by far the largest organic carbon 9 source, estimated to be about 30 to 50 Gt (10 tonnes) per year (Berger et al. 1989; Hedges and Keil 1995). By comparison, rivers contribute -1 about 0. 15 to 0. 23 Gt y of particulate organi.
Download or read book Arctic Ocean Sediments Processes Proxies and Paleoenvironment written by R. Stein and published by Elsevier. This book was released on 2008-07-22 with total page 607 pages. Available in PDF, EPUB and Kindle. Book excerpt: Although it is generally accepted that the Arctic Ocean is a very sensitive and important region for changes in the global climate, this region is the last major physiographic province of the earth whose short-and long-term geological history is much less known in comparison to other ocean regions. This lack of knowledge is mainly caused by the major technological/logistic problems in reaching this harsh, ice-covered region with normal research vessels and in retrieving long and undisturbed sediment cores. During the the last about 20 years, however, several international and multidisciplinary ship expeditions, including the first scientific drilling on Lomonosov Ridge in 2004, a break-through in Arctic research, were carried out into the central Artic and its surrounding shelf seas. Results from these expeditions have greatly advanced our knowledge on Arctic Ocean paleoenvironments. Published syntheses about the knowledge on Arctic Ocean geology, on the other hand, are based on data available prior to 1990. A comprehensive compilation of data on Arctic Ocean paleoenvironment and its short-and long-term variability based on the huge amount of new data including the ACEX drilling data, has not been available yet. With this book, presenting (1) detailed information on glacio-marine sedimentary processes and geological proxies used for paleoenvironmental reconstructions, and (2) detailed geological data on modern environments, Quaternary variability on different time scales as well as the long-term climate history during Mesozoic-Tertiary times, this gap in knowledge will be filled.*Aimed at specialists and graduates *Presents background research, recent developments, and future trends*Written by a leading scholar and industry expert
Download or read book The Global Thermohaline Paleocirculation written by Elena Ivanova and published by Springer Science & Business Media. This book was released on 2009-10-03 with total page 326 pages. Available in PDF, EPUB and Kindle. Book excerpt: Originally published in Russian in 2006, this is the first English translation of this important book on paleoceanography and paleoclimatology. Its initial publication was followed by a surge of interest in this subject prompting the author to revise and translate her original work. In the book, she successfully summarizes her own research over recent years and compiles an overview of up-to-date knowledge on past ocean circulation. The key topics include: - Modern thermohaline circulation and main stages of its development during the Cenozoic - Methods and proxies of paleoceanographic reconstruction - Variability of the meridional overturning circulation and paleoceanographic events in the North Atlantic during the last climatic cycle - Influence of the global thermohaline circulation on paleoceanographic events in the Eurasian Arctic seas, the Northern Indian Ocean, and the South China Sea - The role of the thermohaline circulation in global teleconnections in the Antarctic, Eurasian Arctic, northern Pacific and low latitudes Indo-Pacific. Comprehensive investigation of hundreds of international publications and her own results, convinced the author that the global thermohaline circulation controls the remote teleconnections on millennial-scale and partly on centennial-scale, while short-term climate signals are mainly transferred by the atmosphere. This revised and extended English edition provides the latest unpublished data, new figures and modeling results. The extensive reference list contains more than 100 publications and 140 new references.

Download or read book Ecological Comparisons of Sedimentary Shores written by K. Reise and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 392 pages. Available in PDF, EPUB and Kindle. Book excerpt: Sedimentary coasts with their unique forms of life and productive ecosystems are one of the most threatened parts of the biosphere. This volume analyzes and compares ecological structures and processes at sandy beaches, tidal mudflats and in shallow coastal waters all around the world. Analyses of local processes are paired with comparisons between distant shores, across latitudinal gradients or between separate biogeographic provinces. Emphasis is given to suspension feeders in coastal mud and sand, to biogenic stabilizations and disturbances in coastal sediments, to seagrass beds and faunal assemblages across latitudes and oceans, to recovery dynamics in benthic communities, shorebird predation, and to experimental approaches to the biota of sedimentary shores.
Download or read book The Northern North Atlantic written by Priska Schäfer and published by Springer Science & Business Media. This book was released on 2001-04-02 with total page 520 pages. Available in PDF, EPUB and Kindle. Book excerpt: The northern North Atlantic is one of the regions most sensitive to past and present global changes. This book integrates the results of an interdisciplinary project studying the properties of the Greenland-Iceland-Norwegian Seas and the processes of pelagic and benthic particle formation, particle transport, and deposition in the deep-sea sediments. Ice-related and biogeochemical processes have been investigated to decipher the spatial and temporal variability of the production and fate of organic carbon in this region. Isotopic stratigraphy, microfossil assemblages and paleotemperatures are combined to reconstruct paleoceanographic conditions and to model past climatic changes in the Late Quaternary. The Greenland-Iceland-Norwegian Seas can now be considered one of the best studied subbasins of the world`s oceans.
Download or read book The Biology of Decapod Crustacean Larvae written by Klaus Anger and published by CRC Press. This book was released on 2001-06-01 with total page 262 pages. Available in PDF, EPUB and Kindle. Book excerpt: About 90 per cent of the 10,000 known species of the Crustacea Decapoda live in oceans and adjacent coastal and estuarine regions, and most of them pass through a complex life history comprising a benthic (juvenile-adult) and a planktonic (larval) phase. The larvae show a wide array of adaptations to the pelagic environment, including modifications in their functional morphology, anatomy, the molting cycle, nutrition, growth, chemical composition, metabolism, energy partitioning, ecology and behaviour.;All these traits are reviewed in this volume, attempting to promote an integrated, multidisciplinary view of the biology of larval Decapoda and other crustacean taxa. Emphasis is placed on the lesser-known anatomical, bioenergetic and ecophysiological aspects of larval life, as morphology has already been extensively documented. Changes in biological parameters (for example, rates of feeding, growth, metabolism) are shown in successive developmental stages, within individual stages, and as responses to environmental factors. Particular attention is paid to interrelationships between intrinsic phenomena (molting cycle, organogenesis, growth) and the overlaying effects of extrinsic factors (for example, food, temperature, salinity, pollution). Concluding from the available data, major bias and gaps in present knowledge of larval biology are identified and discussed as to their potential significance in future research.

Available in PDF, EPUB and Kindle. Book excerpt: In most natural sciences, modeling is a widespread method of gaining new knowledge about natural and technical systems. This book analyses the concepts of 'model' and 'modeling' in different fields of research. The different methods of modeling as well as the potentials and limits of this concept are reflected and discussed. The book presents a variety of modeling techniques, from mathematical models in climatology, meteorology or oceanography to methods used in morphology, decision-making in ecology and physical modeling in oceanography. In this broad overview regarding modeling, the book is unique.
Download or read book Land Ocean Systems in the Siberian Arctic written by Heidemarie Kassens and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 850 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
