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.

This book was released on 2020 with total page 175 pages. Available in PDF, EPUB and Kindle. Book excerpt: In addition to control by major nutrient elements (nitrogen, phosphorous, and silicon) growth and community composition of marine phytoplankton is also regulated by trace element nutrients (iron, copper, manganese, zinc, cobalt, nickel, and cadmium). Of these, iron is the most influential in the modern ocean, regulating phytoplankton growth and carbon export in high-nutrient low-chlorophyll regimes and exerting an important control on the marine nitrogen cycle through its role in di-nitrogen fixation. The distributions of these metals has the capacity to control primary production and phytoplankton community composition through differences in cellular quotas or metal sensitivities amongst species. The relationship between trace metal distributions and marine microorganisms is coupled; plankton and bacteria shape the distribution, speciation, and redox state of these metals through cellular uptake, recycling processes, and production of specific and non-specific metal chelators. The interplay between these chemical and biological processes has a profound influence on the modern ocean and global biogeochemical cycles. In this work the feedbacks between trace metal nutrients, natural metal-binding chelators, and marine microorganisms are examined in three distinct oceanic environments that encompass some of the major interfaces of trace metals to the ocean. In the upwelled waters of the California Current system field incubations examine the role of light on the uptake and speciation of metals; an important observation from this study was the increase in short-term Fe uptake rates for marine phytoplankton resulting from photochemical reactions of organically bound Fe, a process that may result in a competitive advantage for some phytoplankton species. In the surface waters of the West Florida Shelf a baseline study of the concentrations of bioactive trace metals and Fe-and-Cu binding organic ligands are reported between two seasons; the work identifies important regional and seasonal processes controlling the distributions of these metals and observed divergent mechanisms influencing the cycling of Fe-and-Cu-binding ligands that may act as a bottom-up control on phytoplankton communities in this region. In hydrothermal plumes along the Mid Atlantic Ridge field incubations examine the role of particles and Fe-binding ligands on the stabilization of dissolved Fe input from these vent systems; the experiments demonstrate the importance of colloids, exchange between particle phases, and Fe-binding ligand production in the stabilization of Fe far-field of these vent systems. The results of these studies present mechanistic frameworks to contextualize some of the basin-scale distributions of these metals generated from the GEOTRACES program. As the GEOTRACES program shifts progressively towards more process oriented studies this work may serve as a useful framework to test hypotheses and further characterize biogeochemical cycles of trace metals in these marine environments.

Book excerpt: The most respected reference in the field--and a fascinating tourof the world's largest underwater greenhouse . . . MARINE BOTANY Second Edition Unmatched in detail and breadth, this Second Edition of MarineBotany explores the startling diversity and environmental dynamicsof the hundreds of micro- and macroalgae, seagrasses, mangroves,and salt marshes as well as phytoplankton (minute, free-floatingphotosynthetic plants) and benthic communities (attached plants)that comprise the flourishing botanical garden submerged in andaround the surface of our vast oceans. Reflecting the latest in research since the original 1981 edition,long considered the classic reference on marine plant life, thisnew edition's enhanced ecological perspective details the ongoingenvironmental challenges endured by these fragile life-forms.Viewing the structure and function of marine plant communities inthe context of abiotic (light, temperature, water movement,nutrients), biotic (photosynthesis, carbon fixation, competition,predation, symbiosis), and anthropogenic influences, the book moveslayer by layer through the ocean, capturing their photosyntheticand adaptive mechanisms. Pollution in the form of oil spills, heavyand radioactive metals, biological damage wrought from harvestingand aquaculture, and the harmful effects of ozone depletion andUV-B rays are detailed, along with the impact of environmentalfactors on morphological and anatomical adaptations. The book alsodescribes the anthropogenic stresses endured by salt marshes,mangals, seagrass communities, and marine plants of coral reefs,concluding with possible management and restorativetechniques. Marine Botany, Second Edition is both a vivid global map andcomprehensive guide to all of the flourishing forms of plant lifeat our oceans' surface, shores, and depths and the dynamics oftheir survival.

This book was released on 1993-02-01 with total page 497 pages. Available in PDF, EPUB and Kindle. Book excerpt: Close to one-half of all Americans live in coastal counties. The resulting flood of wastewater, stormwater, and pollutants discharged into coastal waters is a major concern. This book offers a well-delineated approach to integrated coastal management beginning with wastewater and stormwater control. The committee presents an overview of current management practices and problems. The core of the volume is a detailed model for integrated coastal management, offering basic principles and methods, a direction for moving from general concerns to day-to-day activities, specific steps from goal setting through monitoring performance, and a base of scientific and technical information. Success stories from the Chesapeake and Santa Monica bays are included. The volume discusses potential barriers to integrated coastal management and how they may be overcome and suggests steps for introducing this concept into current programs and legislation. This practical volume will be important to anyone concerned about management of coastal waters: policymakers, resource and municipal managers, environmental professionals, concerned community groups, and researchers, as well as faculty and students in environmental studies.
