Available in PDF, EPUB and Kindle. Book excerpt: Our desire to understand the global carbon cycle and its link to the climate system represents a huge challenge. These overarching questions have driven a great deal of scientific endeavour in recent years: What are the basic oceanic mechanisms which control the oceanic carbon reservoirs and the partitioning of carbon between ocean and atmosphere? How do these mechanisms depend on the state of the climate system and how does the carbon cycle feed back on climate? What is the current rate at which fossil fuel carbon dioxide is absorbed by the oceans and how might this change in the future? To begin to answer these questions we must first understand the distribution of carbon in the ocean, its partitioning between different ocean reservoirs (the "solubility" and "biological" pumps of carbon), the mechanisms controlling these reservoirs, and the relationship of the significant physical and biological processes to the physical environment. The recent surveys from the JGOFS and WOCE (Joint Global Ocean Flux Study and World Ocean Circulation Ex periment) programs have given us a first truly global survey of the physical and biogeochemical properties of the ocean. These new, high quality data provide the opportunity to better quantify the present oceans reservoirs of carbon and the changes due to fossil fuel burning. In addition, diverse process studies and time-series observations have clearly revealed the complexity of interactions between nutrient cycles, ecosystems, the carbon-cycle and the physical envi ronment.

Available in PDF, EPUB and Kindle. Book excerpt: The oceans and atmosphere interact through various processes, including the transfer of momentum, heat, gases and particles. In this book leading international experts come together to provide a state-of-the-art account of these exchanges and their role in the Earth-system, with particular focus on gases and particles. Chapters in the book cover: i) the ocean-atmosphere exchange of short-lived trace gases; ii) mechanisms and models of interfacial exchange (including transfer velocity parameterisations); iii) ocean-atmosphere exchange of the greenhouse gases carbon dioxide, methane and nitrous oxide; iv) ocean atmosphere exchange of particles and v) current and future data collection and synthesis efforts. The scope of the book extends to the biogeochemical responses to emitted / deposited material and interactions and feedbacks in the wider Earth-system context. This work constitutes a highly detailed synthesis and reference; of interest to higher-level university students (Masters, PhD) and researchers in ocean-atmosphere interactions and related fields (Earth-system science, marine / atmospheric biogeochemistry / climate). Production of this book was supported and funded by the EU COST Action 735 and coordinated by the International SOLAS (Surface Ocean- Lower Atmosphere Study) project office.
Download or read book Understanding Climate Change Feedbacks written by National Research Council and published by National Academies Press. This book was released on 2003-12-02 with total page 166 pages. Available in PDF, EPUB and Kindle. Book excerpt: During the past decade, scientists have learned much about the complex natural processes that influence climate variability and change, and our ability to model climate has increased significantly. We also have begun to better identify those parts of the climate system that are particularly important and not well understood and that therefore limit our ability to project the future evolution of Earth's climate. One of these critical areas is our understanding of the role of feedbacks in the climate system and their role in determining climate sensitivity. Feedbacks are processes in the climate system that can either amplify or dampen the system's response to changed forcings. This study looks at what is known and not known about climate change feedbacks and seeks to identify the feedback processes most in need of improved understanding. It identifies key observations needed to monitor and understand climate feedbacks, discusses ways to evaluate progress in understanding climate feedbacks, recommends ways to improve climate modeling and analysis for climate feedbacks research, and identifies priority areas for research.
Download or read book The Changing Ocean Carbon Cycle written by Roger B. Hanson and published by Cambridge University Press. This book was released on 2000-01-13 with total page 540 pages. Available in PDF, EPUB and Kindle. Book excerpt: The world's oceans act as a reservoir, with the capacity to absorb and retain carbon dioxide. The air-sea exchange of carbon is driven by physico-chemical forces, photosynthesis, and respiration, and has an important influence on atmospheric composition. Variability in the ocean carbon cycle could therefore exert significant feedback effects during conditions of climate change. The Joint Global Ocean Flux Study (JGOFS) is the first multidisciplinary program to directly address the interactions among the biology, chemistry, and physics of marine systems, with emphasis on the transport and transformations of carbon within the ocean and across its boundaries. This unique volume, written by an international panel of scientists, provides a synthesis of JGOFS science and its achievements to date. The authoritative chapters will be of great interest to readers seeking a current overview of the role of ocean processes in Earth system science and their wider implications for climate change.

Download or read book Ocean Biogeochemistry written by Michael J.R. Fasham and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 324 pages. Available in PDF, EPUB and Kindle. Book excerpt: Oceans account for 50% of the anthropogenic CO2 released into the atmosphere. During the past 15 years an international programme, the Joint Global Ocean Flux Study (JGOFS), has been studying the ocean carbon cycle to quantify and model the biological and physical processes whereby CO2 is pumped from the ocean's surface to the depths of the ocean, where it can remain for hundreds of years. This project is one of the largest multi-disciplinary studies of the oceans ever carried out and this book synthesises the results. It covers all aspects of the topic ranging from air-sea exchange with CO2, the role of physical mixing, the uptake of CO2 by marine algae, the fluxes of carbon and nitrogen through the marine food chain to the subsequent export of carbon to the depths of the ocean. Special emphasis is laid on predicting future climatic change.

This book was released on 2013-11-22 with total page 544 pages. Available in PDF, EPUB and Kindle. Book excerpt: Biological processes in the oceans play a crucial role in regulating the fluxes of many important elements such as carbon, nitrogen, sulfur, oxygen, phosphorus, and silicon. As we come to the end of the 20th century, oceanographers have increasingly focussed on how these elements are cycled within the ocean, the interdependencies of these cycles, and the effect of the cycle on the composition of the earth's atmosphere and climate. Many techniques and tools have been developed or adapted over the past decade to help in this effort. These include satellite sensors of upper ocean phytoplankton distributions, flow cytometry, molecular biological probes, sophisticated moored and shipboard instrumentation, and vastly increased numerical modeling capabilities. This volume is the result of the 37th Brookhaven Symposium in Biology, in which a wide spectrum of oceanographers, chemists, biologists, and modelers discussed the progress in understanding the role of primary producers in biogeochemical cycles. The symposium is dedicated to Dr. Richard W. Eppley, an intellectual giant in biological oceanography, who inspired a generation of scientists to delve into problems of understanding biogeochemical cycles in the sea.

Download or read book Ocean Circulation and Climate written by Toste Tanhua and published by Elsevier Inc. Chapters. This book was released on 2013-10-22 with total page 69 pages. Available in PDF, EPUB and Kindle. Book excerpt: Carbon is a fundamental component of all life and its gaseous form, carbon dioxide (CO2), is an important atmospheric regulator of Earth’s climate. Over societally relevant timescales, diverse physical, biological, and chemical processes in the global ocean have a very important role in controlling the exchanges of CO2 with the atmosphere and climate, given that the ocean contains roughly 60 times more carbon than the atmosphere. The complex and dynamic marine carbon cycle is thus a fundamental part and regulator of life on Earth, requiring monitoring of its variability and understanding of the feedbacks to the climate system. This is particularly relevant given that emissions of human produced (anthropogenic) CO2 through fossil fuel and land use changes have led to significant perturbations in the global carbon cycle. A large fraction of emitted anthropogenic carbon (Cant) has been and will be absorbed by the oceans with implications for seawater chemistry, ocean pH levels, and the biological communities contained within. During the last few decades, quantification of the ocean sink of CO2 and its temporal evolution of the marine carbon cycle has been an important driver of marine biogeochemical research. Scientific expeditions such as the World Ocean Circulation Experiment/Joint Global Ocean Flux Study global surveys conducted during the 1990s provided the data for the first global estimates of the uptake and oceanic sink of Cant. More recently, completion of a second global survey of the marine carbon cycle (from 2000 to 2013) provided sufficient data to assess the rate of uptake and storage of Cant within the interior of the global ocean. From this effort, it has become clear that there is substantial regional and temporal variability of the storage rate of Cant and those physico-biogeochemical processes that influence the marine carbon cycle. Here we review seawater carbonate chemistry, the sampling strategies, and networks required to observe variability in the global ocean carbon cycle and the flux of carbon between the ocean and the atmosphere but with a central focus, synthesizing and summarizing available estimates of the ocean uptake and inventories of Cant. This chapter is aimed at a wider audience within the oceanographic community and points to the rich literature on marine carbon cycle research.

This book was released on 2010-10-27 with total page 185 pages. Available in PDF, EPUB and Kindle. Book excerpt: Oceans and the Atmospheric Carbon Content, presents an interdisciplinary overview of the role of the oceans as a carbon sink and its relation with pH increasing trends and climate change. This volume discusses topics such as: climate variability during the last deglaciation, based on a high-resolution pollen analysis; the potential impact of CO2 from large metropolitan areas over the adjacent coastal zones and the importance of having high resolution atmospheric CO2 data to estimate accurately air-sea CO2 exchanges; present- day CO2 fluxes in the coastal ocean and their potential feedbacks under global climate change; phytoplankton community responses to climate change with emphasis on decreasing pH trends in sea water and its ecological effects; pH decrease and its effects on sea-water chemistry from a ten year time-series; the effect of acidification on metal bioaccumulation; the effects of increasing temperatures and acidification on contaminant dynamics and availability to biota; the prevention of potential environmental impacts related to the geological sequestration of CO2. The book provides an updated synthesis of current concerns related to global change trends in the oceans with a strong emphasis on acidification. The content draws attention to the importance of dealing with observed global change trends and their effects upon the oceans using an interdisciplinary approach due to their complexity and interlinks between different areas of knowledge.

Available in PDF, EPUB and Kindle. Book excerpt: The ocean helps moderate climate change thanks to its considerable capacity to store CO2, through the combined actions of ocean physics, chemistry, and biology. This storage capacity limits the amount of human-released CO2 remaining in the atmosphere. As CO2 reacts with seawater, it generates dramatic changes in carbonate chemistry, including decreases in pH and carbonate ions and an increase in bicarbonate ions. The consequences of this overall process, known as "ocean acidification", are raising concerns for the biological, ecological, and biogeochemical health of the world's oceans, as well as for the potential societal implications. This research level text is the first to synthesize the very latest understanding of the consequences of ocean acidification, with the intention of informing both future research agendas and marine management policy. A prestigious list of authors has been assembled, among them the coordinators of major national and international projects on ocean acidification.
