This book was released on 1975 with total page 168 pages. Available in PDF, EPUB and Kindle. Book excerpt: A computer model simulating the seasonal variations, of mixed layer nutrient concentrations, phytoplankton biomass carbon, and herbivorous zooplankton biomass carbon was developed. The simulation was generated using an annual cycle of four environmental parameters: (1) incident solar radiation, (2) upwelling velocity, (3) mixed layer depth, and (4) mixed layer temperature. Simulation results were compared with nutrient and zooplankton biomass data collected on a series of seven cruises made in central Monterey Bay from February through December, 1974. Both observed and simulation zooplankton stocks were characterized by two distinct maxima. The initial peak (1.05 gC/sq m) occurred in late July and was followed by a decline in populations through the month of August. During the fall and early winter, zooplankton biomass increased rapidly to an overall maximum of 1.85 gC/sq m. Individual environmental parameters were tested to ascertain their importance in controlling simulation results. Phytoplankton stocks were influenced principally by changes in incident radiation, whereas temperature variations produced the most significant fluctuations in zooplankton biomass.

Download or read book Carbon Cycles and Climate written by Jerry S. Olson and published by . This book was released on 1980 with total page 260 pages. Available in PDF, EPUB and Kindle. Book excerpt: This partially annotated bibliography contains the first 1000 references from a computerized file of literature on the global ecological implications of carbon cycles and climatic changes. Many early citations originated from the Biogeochemical Ecological Information Center established at Oak Ridge National Laboratory in 1968 and from profiles of computerized files such as Government Research Abstracts (GRA) and Biological Abstracts (BA). Later citations have been extracted from the open literature through 1978 and early 1979, from government reports and impact statements, and from profiles of GRA, BA, and the Energy Data Base of the Department of Energy Technical Information Center, Oak Ridge, Tennessee. The subject categories covered by this bibliography may be divided into two main topics: carbon cycling and climate system analysis. Volume I contains an introduction and overview. Volume 2 contains an alphabetical (by author) listing of citations. Volume 3 provides indexes for author, organization (corporate authority), keywords (or free index terms), taxonomic category, subject category, Chemical Abstracts codes, Biological Abstracts codes (crosscode), and COSATI/Weekly Government Abstracts codes concentrated with permuted title words.

This book was released on 2013-11-21 with total page 304 pages. Available in PDF, EPUB and Kindle. Book excerpt: Masters Theses in the Pure and Applied Sciences was first conceived, published, and dis seminated by the Center for lnformation and Numerica/ Data Analysis and Synthesis (C/NDAS) * at Purdue University in 1957, starting its coverage of theses with the academic year 1955. Beginning with Volume 13, the printing and dissemination phases of the ac tivity were transferred to University Microfilms/Xerox of Ann Arbor, Michigan, with the thought that such an arrangement would be more beneficia! to the academic and general scientific and technical community. After fi ve years of this joint undertaking we had concluded that it was in the interest of ali concerned if the printing and distribution of the volume were handled by an international publishing house to assure improved service and broader dissemination. Hence, starting with Volume 18, Masters Theses in the Pure and App/ied Sciences has been disseminated on a worldwide basis by Plenum Publishing Corporation of New York, and in the same year the coverage was broadened to include Canadian universities. Ali back issues can also be ordered from Plenum. We have reported in Volume 21 (thesis year 1976) a total of 10,586 theses titles from 25 Canadian and 219 United States universities. We are sure that this broader base for theses titles reported will greatly enhance the value of this important annual reference work.

This book was released on 1976 with total page 200 pages. Available in PDF, EPUB and Kindle. Book excerpt: A computer simulation model of the phosphate, phytoplankton and zooplankton dynamics in Monterey Bay was examined and modified. The model is driven by four forcing functions expressed as annual cycles of upwelling velocity, incident solar radiation, mixed layer depth, and mixed layer temperature. An alternate upwelling index was developed based on the local wind field. A revised radiation index is employed based on the generation of both advection fog and low stratus cloud cover common during upwelling on the California coast. Analysis of the model's response to sinking and advection of phytoplankton was examined. The importance of seasonal increases in predators was introduced as a controlling factor in the seasonal growth of zooplankton. The model is able to predict the seasonal trends of phosphate, phytoplankton, and zooplankton throughout the year. (Author).

Available in PDF, EPUB and Kindle. Book excerpt: Upwelling systems are special places in the oceans where nutrient-enriched water is brought into the euphotic zone to fuel phytoplankton blooms that, via marine food-web interactions, create the world’s richest fish resources. This book introduces the reader to the interdisciplinary science of upwelling and provides a comprehensive overview of the world’s most productive marine ecosystems in the context of climate variability, climate change and human exploitation. This material presented is suitable for undergraduate and postgraduate study or just for anyone interested to learn about the creation of life in the oceans and how this is compromised by human activities.
