This book provides a comprehensive overview of the taxonomy, biology, sedimentation, and carbonate geochemistry of modern species. Students, early career and advanced scientists alike will profit from a broad synthesis of the current understanding of planktic foraminifers as an ecological indicator, biogeochemical factories, and proxies in paleoceanography. The classification of modern species is amply illustrated with electron and light microscope images of morphotypes, addresses the state-of-the-art of molecular genetics of species, and provides a detailed guide for any laboratory analyses. The biology of planktic foraminifers is extensively discussed in chapters dedicated to the cellular ...
Explores the ever-present experiences of risk that characterized the daily existence of individuals, communities, and societies in the late Roman world Living with Risk in the Late Roman World explores the ever-present experiences of risk that characterized the daily existence of individuals, communities, and societies in the late Roman world (late third century CE through mid-sixth century CE). Recognizing the vital role of human agency, author Cam Grey bases his argument on the concept of the riskscape: the collection of risks that constitute everyday lived experience, the human perception of those risks, and the actions that exploit, mitigate, or exacerbate them. In contrast to recent gra...
This is a guide to imaging techniques for sedimentologists, paleolimnologists, paleoceanographers and microscopists involved in paleoenvironmental reconstruction. Case studies illustrate the range of information obtainable from different sediments (marine, lacustrine, aeolian) and different types of samples (cores, embedded blocks, microscopic slides) using different regions of the electromagnetic spectrum (visible, UV, IR, X-ray). Includes comprehensive protocols, guidelines, and recommendations for the use of low cost image analysis techniques.
The marine iodine cycle has remained enigmatic despite decades of research. As a redox active element that is accumulated by many marine organisms, it exists in multiple oxidation states and phases in the oceans. Abiotic, photochemical and biological processes occurring at the ocean surface, at depth, and at the sediment-water interface all drive transformations between iodine species. A recent resurgence in interest in marine iodine speciation has been driven by its importance in a diverse range of fields, from atmospheric chemistry to paleoceanography.
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 N...

The oceans cover 70% of the Earth’s surface, and are critical components of Earth’s climate system. This new edition of Encyclopedia of Ocean Sciences, Six Volume Set summarizes the breadth of knowledge about them, providing revised, up to date entries as well coverage of new topics in the field. New and expanded sections include microbial ecology, high latitude systems and the cryosphere, climate and climate change, hydrothermal and cold seep systems. The structure of the work provides a modern presentation of the field, reflecting the input and different perspective of chemical, physical and biological oceanography, the specialized area of expertise of each of the three Editors-in-Chie...
MARGO - Multiproxy Approach for the Reconstruction of the Glacial Ocean surface summarizes the results of the MARGO international working group, with the aim to develop an updated and harmonised reconstruction of sea surface temperatures and sea-ice extent of the Last Glacial Maximum oceans. The MARGO approach differs from previous efforts by developing and consistently applying measures of various aspects of reconstruction reliability, and by combining faunal and geochemical proxies. In 14 papers, the volume provides a comprehensive review of earlier work and a series of new, proxy-specific reconstructions based on census counts of planktonic foraminifera, diatoms, radiolaria and dinoflagel...
