Book Synopsis Seasonal Carbon Cycling in the Sargasso Sea Near Bermuda by : Nicolas Gruber
Download or read book Seasonal Carbon Cycling in the Sargasso Sea Near Bermuda written by Nicolas Gruber and published by Univ of California Press. This book was released on 1999-10-04 with total page 106 pages. Available in PDF, EPUB and Kindle. Book excerpt: Each year, the concentration of dissolved inorganic carbon (DIC) in the mixed layer at Station S in the Sargasso Sea decreases from winter to summer by about 30 umol/kg. The authors of this study demonstrate that by simultaneously observing changes in the stable isotopic ration of DIC, it is possible to quantify the contribution of physical and biological processes to this summer-fall drawdown. They find that biology is the dominant contrbutor to the drawdown, but that physical processes also play an important role.

Book excerpt: Covering 71 percent of the planet, these saline bodies of water provided the unique conditions necessary for the building blocks of life to form billions of years ago. This book explains how our oceans continue to support and influence life in important ways: by providing the largest global source of protein in the form of fish populations, by creating and influencing weather systems, and by absorbing waste streams such as airborne carbon. It is shown how oceans have an almost magnetic draw—almost half of the world’s population lives within a few hours of an ocean. Although oceans are vast in size, exceeding 328 million cubic miles (1.37 billion cubic kilometers), they have been influenced by and have influenced humans in numerous ways. The book includes three detailed case studies. The first focuses on the most remote locations along the Mid-Atlantic Ridge, where new ocean floor is being formed twenty-thousand feet underwater. The second considers the Maldives, a string of islands in the Indian Ocean, where increasing sea levels may force residents to abandon some communities by 2020. The third describes the North Sea at the edge of the Arctic Ocean, where fishing stocks have been dangerously depleted as a result of multiple nations’ unrelenting removal of the smallest and largest species.

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 Chemical Reference Materials by : National Research Council
Download or read book Chemical Reference Materials written by National Research Council and published by National Academies Press. This book was released on 2002-11-02 with total page 146 pages. Available in PDF, EPUB and Kindle. Book excerpt: The accuracy of chemical oceanographic measurements depends on calibration against reference materials to ensure comparability over time and among laboratories. Several key parameters lack reference materials for measurements in seawater, particles in the water column, and sediments. Without reference materials it is difficult to produce the reliable data sets or long-term baseline studies that are essential to verify global change and oceanic stability. Chemical Reference Materials : Setting the Standards for Ocean Science identifies the most urgently required chemical reference materials based on key themes for oceanographic research and provides suggestions as to how they can be developed within realistic cost constraints. Chemical analyses of seawater are uniquely difficult given the poorly known speciation and the low concentration of many of the analytes of interest. Analyses of suspended and sedimentary marine particulate materials present their own distinct challenges, primarily due to potential interference by predominant mineral phases of different types. Of all the analytical methods applied to marine waters and particles, at present only a small fraction can be systematically evaluated via comparison to reference materials that represent the appropriate natural concentrations and matrices. Specifically, the committee was charged with the following tasks: - compile from available sources a list of important oceanographic research questions that may benefit from chemical reference standards; - create a comprehensive list of reference materials currently available for oceanographic studies; - identify and prioritize the reference materials needed to study the identified research questions; - determine for each priority analyte whether reference materials and/or analytic methods should be standardized; and - identify the most appropriate approaches for the development and future production of reference materials for ocean sciences.

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 Patterns and Drivers of Nearshore Coastal Air-sea CO2 Exchange by : Kirstin Lee Skadberg
Download or read book Patterns and Drivers of Nearshore Coastal Air-sea CO2 Exchange written by Kirstin Lee Skadberg and published by . This book was released on 2008 with total page 210 pages. Available in PDF, EPUB and Kindle. Book excerpt: CO2 uptake in a nearshore coastal ocean was directly measured using eddy covariance over 27 months in the mid-latitude eastern Pacific. The average annual CO2 uptake during the study was 11.8 mol C m−2yr−1 roughly 25 times greater than the global ocean average. Distinct temporal patterns of CO2 uptake were resolved at diurnal, and seasonal scales. Regression analysis of variance indicates that the major drivers of the observed patterns of uptake are related to photosynthesis, with both photosynthetically active radiation and sea surface temperature explaining more of the variability than wind. Warmer sea surface temperatures were correlated with stronger CO2 uptake, the opposite of what would be expected if the "solubility pump" were in action. Air-sea CO2 flux values calculated using the pCO2 data and a constant k value of 10 cm hr−1 were only 25% of the magnitude of direct eddy covariance measurements. The average k value calculated using eddy covariance CO2 flux and delta pCO2 values was 48.8 cm hr−1. Use of the eddy covariance method to directly measure CO2 exchange at the air-sea interface in coastal waters avoids key uncertainties encountered when exchange is calculated using pCO2 differences and k-wind speed relationships, and it is suggested that the discrepancies that have been observed between eddy covariance CO2 flux measurements and pCO2 models could be the result of inadequate inclusion of complexities in pCO2 models, and that direct measurement via eddy covariance is the preferred method in coastal regions. It is concluded that global kelp and sea grass communities could be taking up as much as 2.1 x 1014 g C (0.21 Pg C) of atmospheric CO2 each year. Therefore, macrophyte ecosystems, which comprise between 0.6-2.2% of the surface area of the ocean could be responsible for as much as 10% of the value currently estimated for total global ocean CO2 uptake

This book was released on 2008-06-05 with total page 880 pages. Available in PDF, EPUB and Kindle. Book excerpt: The proliferation of harmful phytoplankton in marine ecosystems can cause massive fish kills, contaminate seafood with toxins, impact local and regional economies and dramatically affect ecological balance. Real-time observations are essential for effective short-term operational forecasting, but observation and modelling systems are still being developed. This volume provides guidance for developing real-time and near real-time sensing systems for observing and predicting plankton dynamics, including harmful algal blooms, in coastal waters. The underlying theory is explained and current trends in research and monitoring are discussed.Topics covered include: coastal ecosystems and dynamics of harmful algal blooms; theory and practical applications of in situ and remotely sensed optical detection of microalgal distributions and composition; theory and practical applications of in situ biological and chemical sensors for targeted species and toxin detection; integrated observing systems and platforms for detection; diagnostic and predictive modelling of ecosystems and harmful algal blooms, including data assimilation techniques; observational needs for the public and government; and future directions for research and operations.
