Available in PDF, EPUB and Kindle. Book excerpt: Explores how two coastal ecosystems are responding to the pressures of human expansion The Northern Adriatic Sea, a continental shelf ecosystem in the Northeast Mediterranean Sea, and the Chesapeake Bay, a major estuary of the mid-Atlantic coast of the United States, are semi-enclosed, river-dominated ecosystems with urbanized watersheds that support extensive industrial agriculture. Coastal Ecosystems in Transition: A Comparative Analysis of the Northern Adriatic and Chesapeake Bay presents an update of a study published two decades ago. Revisiting these two ecosystems provides an opportunity to assess changing anthropogenic pressures in the context of global climate change. The new insights can be used to inform ecosystem-based approaches to sustainable development of coastal environments. Volume highlights include: Effects of nutrient enrichment and climate-driven changes on critical coastal habitats Patterns of stratification and circulation Food web dynamics from phytoplankton to fish Nutrient cycling, water quality, and harmful algal events Causes and consequences of interannual variability The American Geophysical Union promotes discovery in Earth and space science for the benefit of humanity. Its publications disseminate scientific knowledge and provide resources for researchers, students, and professionals. Read a review of this book in Marine Ecology review of this book

Download or read book Carbon Cycling in the Baltic Sea written by Karol Kulinski and published by Springer Science & Business Media. This book was released on 2012-01-05 with total page 139 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Baltic Sea is an area extensively explored by the oceanographers. Hence it is one of the most often described marine areas in the scientific literature. However, there are still several fields which are poorly investigated and reported by scientists. One of them is the carbon cycle of the Baltic Sea. Although it is believed the shelf seas are responsible for about 20% of all marine carbon dioxide uptake, while they constitute only 7% of the whole sea surface, still a scientific debate exists on the role of the Baltic Sea in the global carbon cycle. “Carbon cycle of the Baltic Sea” is intended to be a comprehensive presentation and discussion of state of the art research by biogeochemists involved in the Baltic Sea carbon cycle research. This work presents both qualitative and quantitative descriptions of the main carbon flows in the Baltic Sea as well as their possible shifts induced by climatic and global change.

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.

Book excerpt: "The role of C02 and the cycling of carbon through the earth's oceans and atmosphere have been focal points in the discussion of the effect of humanity on the earth. The sources, sinks, and cycling mechanisms of C02 are important, and still widely disputed, variables in both their potential for affecting the earth's climate and in the development of accurate models of ocean circulation. The National Oceanographic Data Center (NODC) is pleased to present the attendees of the Second Scientific Meeting of The Oceanography Society with this special publication, C02 Transport and Transformation in the Ocean. This publication provides a list of recent reference works about C02 transport, which were found by searching several online files and several CD-ROM products available at the National Oceanic and Atmospheric Administration (NOAA) Library"--Introduction

Download or read book An Investigation of the Distribution of Carbon Dioxide Between the Atmosphere and the Sea written by Edward R. Ibert and published by . This book was released on 1963 with total page 306 pages. Available in PDF, EPUB and Kindle. Book excerpt: Measurements of the distribution of CO 2 between the atmosphere and the sea are presented with a description of the apparatus used and its calibration. The measurements were made on a series of cruises into the Gulf of Mexico, the Northern Caribbean Sea and the Western North Atlantic Ocean, in the gas phase using a nondispersive double-beam infrared analyzer. Four geographical patterns in the distribution of CO2 between the phases were observed; first, pCO2 of the air over the Southwestern Gulf of Mexico, the Gulf of Campeche and a 40 mile wide strip near shore of the Louisiana Gulf Coast was 303 ppm and pCO2 of the surface waters was 270-290 ppm. The second, bounded by the Bahama Banks, the island of Bermuda and the continental United States, has a pCO 2 of 311 to 312 ppm in the air and PCO2 of the waters was 290 ppm. A diurnal cycle in pCO2 of the air of 4-8 ppm was observed over this area. The maximum occurred at 1800 hours local time and the minimum between 2400 and 0600. The third, consisting of the Northern Caribbean and Atlantic south of the Bahama Banks, where pCO2 of the air was 316 ppm and pCO2 of the surface waters was between 270 and 300 ppm. A tropical rain squall in this area produced large excursions to 330 ppm of pCO2 in the sea to a depth of 200 feet. The fourth, the Eastern Gulf of Mexico from the straits of Florida to the mouth of the Mississippi River, pCO2 in the air averaged 316 ppm and pCO2 of the sea was above 325 ppm. A diurnal cycle of 70 ppm in the pCO2 of the sea was observed in the Gulf of Batabano, Cuba, the maximum was 400 ppm at the time of maximum insolation and the minimum occurred before dawn. The change in pCO2 per degree centigrade in sea water of 19% chlorinity and pH of 8.2 was measured and is a 4.5 ppm. The change in pCO2 with temperature is a function of pH and for the same water is 7. 0 ppm per degree at pH of 8.0.

Download or read book Field Observations And Novel Methodologies For Carbon System Assessments In Coastal Waters written by Bo Yang and published by . This book was released on 2015 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Coastal zones receive massive terrestrial inputs of nutrients and organic matter, and play an important role in biogeochemical cycles. The interactions of river inputs, ocean currents, atmospheric exchanges, anthropogenic influences, and biologically active ecosystems make CO2 system studies in coastal waters highly challenging. This work focuses on improving our understanding of the CO2 system in coastal waters through (1) development of a new methodology for measurements of CO2 system parameters in the field; (2) observations of large spatial and temporal CO2 system variations in coastal waters; and (3) characterization of the influence of organics on CO2 system behavior in coastal waters. A novel portable light-emitting-diode (LED) photometer was developed to provide low-cost seawater pH measurements in the field. With meta cresol purple (mCP) as the indicator, the photometer produces pHT measurements within 0.01 units of state-of-the-art spectrophotometric measurements (7.6 pH 8.2, 30 S 36.2, and 15 oC t 30 oC). With a simple do-it-yourself (DIY) construction design, a hundredfold reduction in cost relative to benchtop spectrophotometric systems, and routine calibration-free operation in the field, the DIY photometer is an ideal replacement for pH test strips or consumer-level potentiometric probes. Applications of special interest include education, citizen science, coastal zone monitoring, and aquaculture and aquarium management. Subannual variability of total alkalinity (TA) distributions in the northeastern Gulf of Mexico (GOM) was examined through the use of TA data from ship-based water sampling, historical records of riverine TA, and contemporaneous model output of surface currents and salinity. Variability of TA observed in the upper 150 m of the GOM water column was primarily controlled by subannual variations in the extent of mixing between seawater and river water.

Download or read book Blue Carbon in Shallow Coastal Ecosystems written by Tomohiro Kuwae and published by Springer. This book was released on 2019-09-28 with total page 388 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents a comprehensive and innovative understanding of the role of shallow coastal ecosystems in carbon cycling, particularly marine carbon sequestration. Incorporating a series of forward-looking chapters, the book combines thorough reviews of the global literature and regional assessments--mainly around the Indo-Pacific region and Japan--with global perspectives to provide a thorough assessment of carbon cycling in shallow coastal systems. It advocates the expansion of blue-carbon ecosystems (mangroves, seagrass meadows, and salt marshes) into macroalgal beds, tidal flats, coral reefs, and urbanized shallow waters, demonstrating the potential of these ecosystems as new carbon sinks. Moreover, it discusses not only topics that are currently the focus of blue-carbon studies, i.e., sedimentary carbon stock and accumulation rate, but also CO2 gas exchange between the atmosphere and shallow coastal ecosystems, carbon storage in the water column as refractory organic carbon, and off-site carbon storage. Including highly original contributions, this comprehensive work inspires research beyond the specific regions covered by the chapters. The suite of new concepts and approaches is refreshing and demonstrates that blue-carbon research is indeed a vibrant new field of research, providing deep insights into neglected aspects of carbon cycling in the marine environment. At the same time the book provides guidance for policy makers to deliver benefits to society, for example the inclusion of blue carbon as a carbon offset scheme or the Nationally Determined Contribution (NDC) in the Paris Agreement, and also for building resilience in coastal socio-ecosystems through better management. This book is intended for all those interested in the science and management of coastal ecosystems.

Download or read book The Microbial Fate of Carbon in High-latitude Seas: Impact of the Microbial Loop on Oceanic Uptake of CO[sub 2]. written by and published by . This book was released on 1998 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: This dissertation examines pelagic microbial processes in high-latitude seas, how they affect regional and global carbon cycling, and how they might respond to hypothesized changes in climate. Critical to these interests is the effect of cold temperature on bacterial activity. Also important is the extent to which marine biological processes in general impact the inorganic carbon cycle. The study area is the Northeast Water (NEW) Polynya, a seasonally-recurrent opening in the permanent ice situated over the northeastern Greenland continental shelf. This work was part of an international, multi-disciplinary research project studying carbon cycling in the coastal Arctic. The first chapter describes a simple model which links a complex marine food web to a simplified ocean and atmosphere. The second chapter investigates the inorganic carbon inventory of the summertime NEW Polynya surface waters to establish the effect of biological processes on the air-sea pCO[sub 2] gradient. The third and fourth chapters use a kinetic approach to examine microbial activities in the NEW Polynya as a function of temperature and dissolved organic substrate concentration, testing the so-called Pomeroy hypothesis that microbial activity is disproportionately reduced at low environmental temperatures owing to increased organic substrate requirements. Together, the suite of data collected on microbial activities, cell size, and grazing pressure suggest how unique survival strategies adopted by an active population of high-latitude bacteria may contribute to, rather than detract from, an efficient biological carbon pump.

Book excerpt: During the past five years the Department of Energy (DOE) has supported carbon dioxide studies as part of the Joint Global Ocean Flux Study (JGOFS) on cruises made as part of the World Ocean Circulation Experiment (WOCE). The purpose of this research is to obtain a better understanding of fluxes of carbon, both organic and inorganic, in the world oceans and to place these fluxes into the context of the contemporary global carbon cycle. There is presently a great interest in understanding the carbon dioxide system in the oceans because of the so-called greenhouse effect of CO[sub 2] on climate. Approximately 40% of CO[sub 2] added to the atmosphere due to the burning of fossil fuels is thought to be going into the oceans. In addition the authors are trying to understand the fluxes of carbon to identify the factors and processes which regulate the magnitude and variability of primary productivity, as well as the fate of biogenic materials in the oceans.

This book was released on 2014 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The raise of atmospheric CO2 due to anthropogenic activities is a major driver of the climate change. The ocean plays a key role in the uptake of this anthropogenic CO2. The constraint of air-sea CO2 fluxes and their variability at various time and spatial levels remain a central task in global carbon cycle and climate studies. The contribution of open ocean to this uptake is presently rather well quantified, whereas the role of the coastal ocean to this process remains ambiguous due to the diversity and the high spatio-temporal variability of the CO2 system and air-sea CO2 fluxes in these ecosystems. This PhD thesis investigated the spatial and temporal variability of the CO2 system and air-sea CO2 fluxes in contrasted ecosystems of the north-west European continental shelf. These highly dynamic biogeochemical ecosystems host numerous key hydrographical structures (permanently well-mixed, seasonally stratified, frontal structures, estuarine) of temperate zones, in which the dynamic of the CO2 system were poorly documented. From tidal to multi-annual variability, from a fixed station off Roscoff to the north-west European continental shelf and from seawater samples to satellite data, this PhD thesis provides an integrative overview of the complexity of the CO2 system dynamics in coastal seas and the ongoing challenges to achieve.
