This book was released on 2018-06-03 with total page 42 pages. Available in PDF, EPUB and Kindle. Book excerpt: An ecosystem-carbon cycle model is used to analyze the biogeochemical-physical interactions and carbon fluxes in the Bermuda Atlantic Time-series Study (BATS) site for the period of 1992-1998. The model results compare well with observations (most variables are within 8% of observed values). The sea-air flux ranges from -0.32 to -0.50 mol C/sq m/yr, depending upon the gas transfer algorithm used. This estimate is within the range (-0.22 to -0.83 mol C/sq m/yr) of previously reported values which indicates that the BATS region is a weak sink of atmospheric CO2. The overall carbon balance consists of atmospheric CO2 uptake of 0.3 Mol C/sq m/yr, upward dissolved inorganic carbon (DIC) bottom flux of 1.1 Mol C/sq m/yr, and carbon export of 1.4 mol C/sq m/yr via sedimentation. Upper ocean DIC levels increased between 1992 and 1996 at a rate of approximately 1.2 (micro)mol/kg/yr, consistent with observations. However, this trend was reversed during 1997-1998 to -2.7 (micro)mol/kg/yr in response to hydrographic changes imposed by the El Nino-La Nina transition, which were manifested in the Sargasso Sea by the warmest SST and lowest surface salinity of the period (1992-1998).Signorini, Sergio R. and McClain, Charles R. and Christian, James R.Goddard Space Flight CenterATMOSPHERIC COMPOSITION; BIOGEOCHEMISTRY; CARBON CYCLE; ENVIRONMENT MODELS; ANNUAL VARIATIONS; ALGORITHMS; CARBON DIOXIDE CONCENTRATION; HYDROGRAPHY; SARGASSO SEA; AIR WATER INTERACTIONS; EL NINO; VERTICAL DISTRIBUTION

Book Synopsis Ocean Biogeochemistry by : Michael J.R. Fasham
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.

Book Synopsis Primary Productivity in the Sea by : Paul Falkowski
Download or read book Primary Productivity in the Sea written by Paul Falkowski and published by Springer Science & Business Media. This book was released on 2013-03-09 with total page 530 pages. Available in PDF, EPUB and Kindle. Book excerpt: Primary productivity in the sea accounts for ~30% of the total global annual production. Holistic understanding of the factors determining marine productivity requires detailed knowl edge of algal physiology and of hydrodynamics. Traditionally studies of aquatic primary productivity have heen conducted hy workers in two major schools: experimental laboratory biology, and empirical field ecology. Here an attempt was made .to hring together people from both schools to share information and con cepts; each author was charged with reviewing his field of exoer tise. The scope of the Symposium is broad, which we feel is its strength. We gratefully acknowledge financial support from the Depart ment of Energy, the United States Environmental Protection Agency, the National Oceanic and Atmospheric Administration, including the NMFS Northeast Fisheries Center and the MESA New York Bight Project. Thanks are due to Mrs. Margaret Dienes, with out whose editorial skills this volume could not have been pro duced, and to Mrs. Helen Kondratuk as Symposium Coordinator. Finally, we wish to record our indebtedness to Dr. Alexander Hollaender for his tireless efforts and valuable advice in sup porting all aspects of this Symposium.
Book Synopsis The Changing Ocean Carbon Cycle by : Roger B. Hanson
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.
Book Synopsis Ocean Circulation and Climate by : Christoph Heinze
Download or read book Ocean Circulation and Climate written by Christoph Heinze 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: Biogeochemical ocean general circulation models are important tools for quantifying the marine carbon cycle and its feedback to the climate system. These models simulate the inorganic carbon cycle and also the organic carbon cycle through a series of simplified process parameterizations. This chapter presents an overview of the major concepts and methods in marine biogeochemical modeling including the combination of models with observations. Because of the climatic relevance of the carbon cycle, major emphasis is placed on it, but some other related matter cycles are also touched upon. New developments in ocean biogeochemistry during the last decade are described including the marine anthropogenic carbon uptake and ocean acidification. The chapter tries to acquaint scientists from other disciplines with marine biogeochemical modeling and provides key literature resources for further in-depth studies.
