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 Picophytoplankton Photoacclimation and Mixing in the Surface Oceans written by Jeffrey Allen Dusenberry and published by . This book was released on 1995 with total page 320 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fluctuations in light intensity due to vertical mixing in the open ocean surface layer will affect phytoplankton physiology. Conversely, indicators of phytoplankton photoacclimation will be diagnostic of mixing processes if the appropriate kinetics are known. A combination of laboratory and field experimental work, field observations, and theoretical models were used to quantify the relationship between vertical mixing and photoacclimation in determining the time and space evolution of single cell optical properties for the photosynthetic picoplankton, Prochlorococcus spp. Diel time-series observations from the Sargasso Sea reveal patterns in single-cell fluorescence distributions within Prochlorococcus spp. populations which appear to correspond to decreasing mixing rates and photoacclimation during the day, and increased mixing at night. Reciprocal light shift experiments were used to quantify the photoacclimation kinetics for Prochlorococcus spp. fluorescence. A laboratory continuous culture system was developed which could simulate the effects of mixing across a light gradient at the level of the individual cell. This system was operated at four different simulated diffusivities. Prochlorococcus marinus strain Med4 fluorescence distributions show distinct patterns in the mean and higher moments which are consistent with a simple quasi-steady turbulent diffusionphotoacclimation model. In both, daytime photoacclimation drove the development of a gradient in mean fluorescence, a decrease in variance overall, and skewing of distributions away from the boundaries. These results suggest that picophytoplankton single-cell fluorescence distributions could prove to be a useful diagnostic indicator of the mixing environment.

Download or read book Hypertrophic Ecosystems written by J. Barica and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 337 pages. Available in PDF, EPUB and Kindle. Book excerpt: The idea of convening an international workshop on hypertrophic ecosystems originated during the 20th S.I.L. Congress in Copenhagen. A group of about 30 delegates met there in an informal gathering to discuss the specific problems of lakes which have reached a noxious stage of eutrophication. This ad hoc group realized its own specific identity within the limnological community and suggested the organization of a specialized future meeting on hypertrophic ecosystems. After two years of preparatory work, the workshop was fmally held in Vaxjo, Sweden, between September 10 and 14, 1979, on the premises of the University campus. The Institute of Limnology, University of Lund (Professor Sven Bjork), undertook the task of host and organizer. The City ofVaxjo and the University of Lund co-sponsored the event, which was held under the auspices and patronage of the Societas Internationalis Limnologiae. The objective of the workshop was to seek better understanding of highly-eutrophic, disturbed and unstable aquatic ecosystems (lakes, reservoirs and ponds developing noxious algal and bacterial blooms, fluctuating in their water quality on a daily and seasonal scale, producing gases, off-flavor and toxic substances, experiencing periodic anoxia and massive fish kills, etc.), Le., systems requiring corrective measures and new concepts for their solution beyond those generally accepted for 'normal' eutrophic systems.

This book was released on 2013-11-22 with total page 544 pages. Available in PDF, EPUB and Kindle. Book excerpt: Biological processes in the oceans play a crucial role in regulating the fluxes of many important elements such as carbon, nitrogen, sulfur, oxygen, phosphorus, and silicon. As we come to the end of the 20th century, oceanographers have increasingly focussed on how these elements are cycled within the ocean, the interdependencies of these cycles, and the effect of the cycle on the composition of the earth's atmosphere and climate. Many techniques and tools have been developed or adapted over the past decade to help in this effort. These include satellite sensors of upper ocean phytoplankton distributions, flow cytometry, molecular biological probes, sophisticated moored and shipboard instrumentation, and vastly increased numerical modeling capabilities. This volume is the result of the 37th Brookhaven Symposium in Biology, in which a wide spectrum of oceanographers, chemists, biologists, and modelers discussed the progress in understanding the role of primary producers in biogeochemical cycles. The symposium is dedicated to Dr. Richard W. Eppley, an intellectual giant in biological oceanography, who inspired a generation of scientists to delve into problems of understanding biogeochemical cycles in the sea.

This book was released on 2012-12-06 with total page 300 pages. Available in PDF, EPUB and Kindle. Book excerpt: Human beings have a long historical relationship with the coast. Initially it provided food and security, later forming important locations for industrial and commercial development. Now the emphasis has shifted towards leisure and conservation, although the former functions remain crucial. However, it is only very recently that people have started viewing the coast as a common and valuable resource that requires rational utilisation and scientific management in order to sustain its attractiveness. Of course, enlightened management comes only through understanding of the complicated coastal regions, which enables coastal managers to balance pressures from different sectors and to minimize risks. Scientific knowledge will continue to be the most important basis for resolving the conflicts between coastal users and interest groups such as developers and ecologists. Coastal management has also shifted from traditional restorative or remedial actions towards planned avoidance of other conflicts. Despite rapid advancement in coastal sciences over recent decades, most of the major coastal issues have remained outstanding in the agenda. Control of shoreline erosion and protecting sea level rise continue to be crucial problems facing coastal scientists. Destructive coastal storms still cause tremendous damage, particularly in low altitudes. Wetland and estuary reclamation have led to the loss of the most valuable estuary wetlands which are required to sustain biological productivity and biodiversity. This volume includes papers on marine and coastal pollution, eutrophication, aquaculture, conservation and utilization, coastal wetlands, and coastal zone management.
