The Ocean Carbon Cycle and Climate by Mick Follows,Temel Oguz Pdf

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.

The Global Carbon Cycle by Christopher B. Field,Michael R. Raupach Pdf

While a number of gases are implicated in global warming, carbon dioxide is the most important contributor, and in one sense the entire phenomena can be seen as a human-induced perturbation of the carbon cycle. The Global Carbon Cycle offers a scientific assessment of the state of current knowledge of the carbon cycle by the world's leading scientists sponsored by SCOPE and the Global Carbon Project, and other international partners. It gives an introductory over-view of the carbon cycle, with multidisciplinary contributions covering biological, physical, and social science aspects. Included are 29 chapters covering topics including: an assessment of carbon-climate-human interactions; a portfolio of carbon management options; spatial and temporal distribution of sources and sinks of carbon dioxide; socio-economic driving forces of emissions scenarios. Throughout, contributors emphasize that all parts of the carbon cycle are interrelated, and only by developing a framework that considers the full set of feedbacks will we be able to achieve a thorough understanding and develop effective management strategies. The Global Carbon Cycle edited by Christopher B. Field and Michael R. Raupach is part of the Rapid Assessment Publication series produced by the Scientific Committee on Problems of the Environment (SCOPE), in an effort to quickly disseminate the collective knowledge of the world's leading experts on topics of pressing environmental concern.

Ocean Biogeochemistry by Michael J.R. Fasham Pdf

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.

Marine Geochemistry by Matthieu Roy-Barman,Catherine Jeandel Pdf

Marine geochemistry uses chemical elements and their isotopes to study how the ocean works in terms of ocean circulation, chemical composition, biological activity and atmospheric CO2 regulation. This rapidly growing field is at a crossroad for many disciplines (physical, chemical and biological oceanography, geology, climatology, ecology, etc.). It provides important quantitative answers to questions such as: What is the deep ocean mixing rate? How much atmospheric CO2 is pumped by the ocean? How fast are pollutants removed from the ocean? How do ecosystems react to anthropogenic pressure? This text gives a simple introduction to the concepts, the methods and the applications of marine geochemistry with a particular emphasis on isotopic tracers. Overall introducing a very large number of topics (physical oceanography, ocean chemistry, isotopes, gas exchange, modelling, biogeochemical cycles), with a balance of didactic and indepth information, it provides an outline and a complete course in marine geochemistry. Throughout, the book uses a hands-on approach with worked out exercises and problems (with answers provided at the end of the book), to help the students work through the concepts presented. A broad scale approach is take including ocean physics, marine biology, ocean-climate relations, remote sensing, pollutions and ecology, so that the reader acquires a global perspective of the ocean. It also includes new topics arising from ongoing research programs. This textbook is essential reading for students, scholars, researchers and other professionals.

Climate Change and the Oceanic Carbon Cycle by Isabel Ferrera Pdf

This title includes a number of Open Access chapters. This valuable compendium provides an overview of the variables and consequences of oceanic carbon cycling in the context of climate change. The chapters highlight the importance of marine plankton in carbon processing as well as the effects of rising CO2 and temperature in their functioning. Marine ecosystems are being increasingly threatened by growing human pressures, including climate change. Understanding the consequences that climate change may have is crucial to predict the future of our oceans. Rising temperatures and ocean acidification may profoundly alter the mode of matter and energy transformation in marine ecosystems, which could have irreversible consequences for our planet on ecological timescales. For that reason, the scientific community has engaged in the grand challenge of studying the variables and consequences of oceanic carbon cycling in the context of climate change, which has emerged as a relevant field of science. The book is broken into four sections: Understanding the Importance of Ocean Biogeochemistry Quantifying Oceanic Carbon Variables Phytoplankton and Oceanic Carbon Cycle Ocean Acidification Edited by a researcher with many years of experience and with contributions from scientists from around the world, this volume explores the most important topics on climate change and oceanic carbon cycling.

Climate Change and the Oceanic Carbon Cycle by Anonim Pdf

The carbon cycle in the Earth System constitutes a fundamental, pressing research topic in modern Earth system science. The greenhouse gases carbon dioxide (CO2) and methane (CH4) provide an important forcing factor of the global climate, which, on the other hand, controls the sources and sinks of these gases. In addition, the carbon cycle is currently being seriously perturbed by direct and indirect emissions from human activities. Unraveling and quantifying these interactions and feedbacks is essential to understand the climate history of the Earth, but also to predict its evolution in the future. The ocean is important to climate change and global warming-as a storer and transporter of heat and carbon-but our understanding of the operative processes is inadequate to make predictions with the required skill. CO2 increases will lead to the increased carbon storage by the land and ocean. Climate change will reduce the land and ocean's capacity to absorb atmospheric CO2 due to the increasing temperatures of both the land and ocean and increasing oceanic stratification. The ocean, which has absorbed 27.9% of the anthropogenic CO2 in the past 200 years, plays a crucial role in the global carbon cycle. Climate Change and the Oceanic Carbon Cycle provides complete understanding of the variables and consequences of oceanic carbon cycling in the context of climate change. It reviews the ocean's role in the global CO2 cycle and climate change; describe the importance of mesoscale processes in the ocean; examine the main pathways of carbon exchange between the ocean surface layer and the ocean interior; analyze the scales of the physical processes involved in nutrient limitation of the "biological pump"; and review the implications for climate change. The contributed chapters explores the importance of marine plankton in carbon processing as well as the effects of rising CO2 and temperature in their functioning.

Global Climate Change and Response of Carbon Cycle in the Equatorial Pacific and Indian Oceans and Adjacent Landmasses by Hodaka Kawahata,Yoshio A. Awaya Pdf

To understand the global warming mechanism, global mapping of primary production was carried out under the GCMAPS program. The program was concerned with marine and terrestrial environmental changes, which affect carbon cycle on the regional and global scales. On the regional scale, warm phase of ENSO (El Niño / Southern Oscillation) has been shown to affect economic activities in many countries. The keyword for understanding mechanism of global warming is ‘primary productivity’. The earth observation satellites (EOS) like the ADEOS of Japan, and the SeaWiFS, Sea Star and Terra of the U.S.A. provided much required data for modeling and verification of primary production estimates on both land and ocean. The knowledge gained during the GCMAPS program has been documented in this book. Interpretation of the data suggests that global warming, which causes temperature and sea level rise, and changes in climate and ecosystems, is likely to have the largest influence on mankind. The first half of this book discuss changes in marine environments. Physical and chemical oceanographic properties of the equatorial Pacific and Indian Oceans are presented. Changes in partial pressure of carbon dioxide, flux and composition of settling particles and biological communities in the surface ocean have also been discussed. In addition to this, over hundred years of environmental records based upon coral skeletons are presented. Estimations of primary production and its utilization in validating satellite imagery data were conducted in the western North Pacific. Primary productivity estimates based upon the validated satellite imagery are presented on the global scale. Climate change modeling of primary production in global oceans is also presented. The latter half of this book deals with changes in terrestrial environments. Primary productivity estimates for different types of ecosystems (e.g., forest, grassland) are presented together with soil carbon dynamics. Also, biomass and productivity estimation and environmental monitoring based upon remote sensing techniques are presented with a model analysis of the relationship between climate perturbations and carbon budget anomalies in global terrestrial ecosystems. This book elucidates integrated aspects of the global carbon cycle involving marine and terrestrial environments. Discusses a current understanding of the biogeochemical processes on land and ocean Provides global mapping of primary production based on satellite imagery data and modelling Presents the latest interpretations of relationships between carbon cycle and climatic change

Global Carbon Cycle and Climate Change by Kirill I︠A︡kovlevich Kondratʹev,Vladimir F. Krapivin,Costas Varotsos Pdf

Professor Kondratyev and his team consider the concept of global warming due to the greenhouse effect and put forward a new approach to the problem of assessing the impact of anthropogenic processes. Considering data on both sources and sinks for atmospheric carbon and various conceptual schemes of the global carbon dioxide cycle, they suggest a new approach to studies of the problem of the greenhouse effect. They assess the role of different types of soil and vegetation in the assimilation of carbon dioxide from the atmosphere, and discuss models of the atmosphere ocean gas exchange and its role in the carbon dioxide cycle, paying special attention to the role of the Arctic Basin. The authors also consider models of other global atmospheric cycles for a range of atmospheric constituents, and conclude by drawing together a range of scenarios on modelling the global carbon cycle.

The Changing Ocean Carbon Cycle by Roger B. Hanson,Hugh W. Ducklow,John G. Field Pdf

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.

Ocean Circulation and Climate by Toste Tanhua,Nicholas R. Bates,Arne Körtzinger Pdf

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.

The Global Carbon Cycle by David Archer Pdf

A must-have introduction to this fundamental driver of the climate system The Global Carbon Cycle is a short introduction to this essential geochemical driver of the Earth's climate system, written by one of the world's leading climate-science experts. In this one-of-a-kind primer, David Archer engages readers in clear and simple terms about the many ways the global carbon cycle is woven into our climate system. He begins with a concise overview of the subject, and then looks at the carbon cycle on three different time scales, describing how the cycle interacts with climate in very distinct ways in each. On million-year time scales, feedbacks in the carbon cycle stabilize Earth's climate and oxygen concentrations. Archer explains how on hundred-thousand-year glacial/interglacial time scales, the carbon cycle in the ocean amplifies climate change, and how, on the human time scale of decades, the carbon cycle has been dampening climate change by absorbing fossil-fuel carbon dioxide into the oceans and land biosphere. A central question of the book is whether the carbon cycle could once again act to amplify climate change in centuries to come, for example through melting permafrost peatlands and methane hydrates. The Global Carbon Cycle features a glossary of terms, suggestions for further reading, and explanations of equations, as well as a forward-looking discussion of open questions about the global carbon cycle.

The Carbon Cycle by T. M. L. Wigley,D. S. Schimel Pdf

Reducing carbon dioxide (CO2) emissions is imperative to stabilizing our future climate. Our ability to reduce these emissions combined with an understanding of how much fossil-fuel-derived CO2 the oceans and plants can absorb is central to mitigating climate change. In The Carbon Cycle, leading scientists examine how atmospheric carbon dioxide concentrations have changed in the past and how this may affect the concentrations in the future. They look at the carbon budget and the "missing sink" for carbon dioxide. They offer approaches to modeling the carbon cycle, providing mathematical tools for predicting future levels of carbon dioxide. This comprehensive text incorporates findings from the recent IPCC reports. New insights, and a convergence of ideas and views across several disciplines make this book an important contribution to the global change literature.
