Download or read book Upwelling Ecosystems written by R. Boje and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 310 pages. Available in PDF, EPUB and Kindle. Book excerpt: Upwelling areas are among the most fertile regions of the ocean. In principle, upwelling is caused by the divergence of the flow in the surface layer of the ocean which arises as a consequence of a particular wind field, the presence of a coastline, or other special conditions. Since deeper oceanic layers are usually enriched wi th nutrients, it is the permanent supply of nutrients which forms the basis for the high producti vi ty of upwelling reg ions. The study of upwelling and its consequences were, for a long time, the task of individual scientists from all disciplines of marine science. Today, it is perhaps the branch of oceanography where interdisciplinary coopera tion has developed best. Becoming aware of the large potential yield of upwelling regions, governments in creased the funds for upwelling research. With research activities developed on a larger scale, interdisciplin ary cooperation became a necessity. On the international level, several symposia documented the rapid development. Three volumes reflect the results of these scientific meetings (Rapp. Proc.-Verb. 159, 1970; Inv. Pesq. 35, 1, 1971; Tethys §.' 1-2, 1974). The present book contains selected papers from the Third Symposium on Upwelling Ecosystems, which was held in Kiel in September 1975. Although the third of a series of meetings, it was the first where the word "ecosystem" stood in the title for a scientific program.

Download or read book Coastal Oceanography of Washington and Oregon written by M.R. Landry and published by Elsevier. This book was released on 1989-03-01 with total page 627 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Washington-Oregon coastal zone is a classical Eastern Boundary Current region. The area is extremely productive, the productivity dependent on near-shore infusions of nutrients into surface layers during wind-driven coastal upwelling. The Washington-Oregon coastline is much more regular than areas off California or off the East Coast, where large capes lend complexity to both the physical environment and the ecosystem response. The relatively straight coastline and broad, deep shelf greatly simplify the physical environment, so that processes responsible for much of the variance are more easily identified. The system response from mid-Oregon northward, although not strictly two-dimensional, is more so than many other coastal areas. Consequently, the system is amenable to the testing of relatively simple models integrating wind forcing with physical, chemical and biological responses in the upper water column.This book is an integrated synthesis of physical, chemical, geological and biological research in a dynamic shelf ecosystem characterized by seasonal, wind-driven upwelling, major river influences, extensive silt deposits, productive pelagic and demersal fisheries, and unique surf-zone communities. The broad scope of the book includes: detailed analyses of physical circulation and sediment transport; production and utilization of organic matter in the marine food web; river influences on regional hydrology and sediment deposition; inputs and inventories of anthropogenic chemicals in the water column and sedimentary deposits. Much of the book is based on primary analyses of previously unpublished data sets. Interdisciplinary approaches are emphasized in models and discussions of coastal upwelling dynamics, hydrographic patterns and anomalies, benthic boundary-layer processes and larval transport, oceanographic influences on commercial stocks, mechanics of chemical cycling and accumulation, and surf-zone production. An extensive index and references complete the book.The book is intended both to document and explain specific regional features of the Washington/Oregon shelf system and, more generally, to illustrate the complexities of interactive influences on the dynamics of coastal ecosystems. Oceanographers, both researchers and students, will be very interested in this book, and it can also be used by governmental agencies and industries dealing with coastal zone management and planning.

Download or read book Global Ecology and Oceanography of Harmful Algal Blooms written by Patricia M. Glibert and published by Springer. This book was released on 2018-04-26 with total page 460 pages. Available in PDF, EPUB and Kindle. Book excerpt: Harmful algal blooms (HABs) - blooms that cause fish kills, contaminate seafood with toxins, or cause human or ecological health impacts and harm to local economies - are occurring more often, in more places and lasting longer than in past decades. This expansion is primarily the result of human activities, through increased nutrient inputs and various aspects of climate change. The Global Ecology and Oceanography of Harmful Algal Blooms (GEOHAB) programme promoted international collaboration to understand HAB population dynamics in various oceanographic regimes and to improve the prediction of HABs. This volume introduces readers to the overarching framework of the GEOHAB programme, factors contributing to the global expansion of harmful algal blooms, the complexities of HABs in different habitats, and the forward-looking issues to be tackled by the next generation of GEOHAB, GlobalHAB. The programme brought together an international team of contributing scientists and ecosystem managers, and its outcomes will greatly benefit the international research community.

Download or read book Physical Processes and Their Influence on Zooplankton Composition and Foraging Opportunities for Seabirds in a Strong Persistent Upwelling Region written by Rachel Eileen Fontana and published by . This book was released on 2013 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: In many of the world's oceans the process of coastal upwelling provides large amounts of nutrients to surface waters. This influx of nutrients causes increased productivity throughout the food web of the nearshore, coastal environment. Due to this high productivity, physical and biological dynamics within these coastal upwelling systems have been studied for many years. Recently, however, variation within coastal upwelling regions has been investigated in greater detail, revealing distinct differences between intermittent and persistent upwelling systems. Fewer investigations have been performed in shelf waters experiencing strong, persistent upwelling. Here, I present three studies conducted within shelf waters downstream of a persistent upwelling region. In these studies, I analyzed small-scale oceanographic features, zooplankton composition, and seabird dynamics. These studies help elucidate the physical and biological oceanography occurring in persistent upwelling zones. Many of the past studies on coastal upwelling along the west coast of North America have been performed in intermittent upwelling systems, such as coastal areas off central Oregon and central California. These systems have shorter duration upwelling events and decreased alongshore wind stress compared to persistent systems, which have longer events and higher alongshore wind stress. Fewer studies have been conducted in strong, persistent upwelling regions such as that of northern California, which is examined here. The various studies on the physical and biological dynamics in intermittent upwelling regions have been used to advance over-arching ideas and explanations of coastal upwelling for all regions. These studies, however, may be most suitable for to explaining dynamics within similar intermittent systems. Recent work has been conducted along the west coast of the United States to differentiate recruitment and intertidal patterns occurring in intermittent versus persistent upwelling regimes. Few in-depth studies, however, have been conducted outside the intertidal within shelf waters of persistent upwelling regions. All studies presented here analyzed various aspects and dynamics within a strong, persistent upwelling system located in the Gulf of the Farallones-Cordell bank region (GOF-CB). The Applied California Current Ecosystem Studies (ACCESS) program (www.accessoceans.org) collected much of the data analyzed in all chapters. This is a partnership between PRBO Conservation Science, Cordell Bank and Gulf of the Farallones National Marine Sanctuaries. Data was collected from April 2004 to September 2010 with three to five cruises occurring per year (April to October). In Chapter 1, I identified and analyzed distinct small-scale ocean front features, thus addressing the characteristics, location, and frequency of occurrence of surface fronts in a strong, persistent upwelling area. I explored this through in situ field observations in the GOF-CB region primarily using ship underway data that can resolve small-scale structures. A variety of surface fronts were found in the GOF-CB region from 2004 to 2010. Many of these fronts had strong density gradients, causing frontogenesis as well as the accumulation of plankton and buoyant materials. The abundance of fronts, however, varied significantly between seasons and years. An increase in front abundance was observed during the upwelling season and in 2005, in comparison to the latter years of this study, particularly 2008. Additionally, in contrast to studies conducted in intermittent upwelling regions, I failed to locate any fronts in this region that are classic upwelling fronts. This study demonstrates that fronts in the GOF-CB region are typically short-lived (time scales shorter than synoptic variability, e.g. upwelling-relaxation cycles) and spatially limited. In general, these small-scale fronts will only be important ecologically if planktonic taxa, and subsequent predators can take advantage of accumulation on these short time scales. In Chapter 2, I examined a zooplankton time series collected within a strong, persistent upwelling region. I analyzed variability in zooplankton abundance and species composition with environmental conditions during the upwelling seasons (April to July) within the GOF-CB region from 2004 to 2009. I found zooplankton abundance and species composition differed significantly, particularly between the first three years (2004 to 2006) and the latter three years (2007 to 2009) of the study. From 2004 to 2006, corresponding environmental measurements showed lower alongshore wind stress, decreased upwelling, minimal alongshore flow, and warmer ocean temperatures throughout the region, whereas 2007 to 2009 demonstrated the opposite patterns at all temporal and spatial scales of environmental measurements. Zooplankton abundance and species composition correlated with several of these environmental variables, including surface flow past Point Reyes and CTD salinity. This signifies a close linkage between this zooplankton time series and basin-wide, regional, and in situ environmental forcing within this strong, persistent upwelling region. Understanding zooplankton abundance and species composition in the GOF-CB region will elucidate population dynamics of upper trophic levels and may assist with future year-to-year predictions of general ecosystem health. In Chapter 3, I investigated the influence of an offshore bank, Cordell Bank (CB), and surrounding hydrographic measurements within this persistent coastal upwelling region on the abundance of two seabird taxa: Cassin's auklet, Ptychorhamphus aleuticus, and dark shearwater (sooty, Puffinus griseus and pink-footed, Puffinus creatopus). I analyzed spatial patterns of the abundance for these two taxa using negative binomial regression models. While both taxa were associated with CB, auklets and shearwaters were found to forage within different sub-regions over and surrounding CB. Abundance of Cassin's auklet was significantly higher in waters offshore and over CB, corresponding with a maximum abundance in surface salinities around 33.30. In contrast, dark shearwater abundance was significantly greater in both lower (33.2) and higher surface (33.5) salinity waters. Higher shearwater abundance was also found in regions with elevated surface temperature gradients, possibly denoting fronts or transition zones between water masses. Understanding seabird dynamics near CB yields insight to the influence banks may have on top predator foraging in strong, persistent upwelling regions. These three studies reveal new insights into the disparate dynamics occurring in strong, persistent coastal upwelling regions, in comparison to the well-studied intermittent upwelling regions. As described throughout this work, small-scale front features, zooplankton composition, and seabird dynamics are affected by the strength and duration of upwelling on multiple temporal scales. Therefore, a distinction between these two regions is necessary to further understand their distinct dynamics and subsequent effects on productivity throughout the food chain.

Available in PDF, EPUB and Kindle. Book excerpt: Almost half the U.S. population lives along the coast. In another 20 years this population is expected to more than double in size. The unique weather and climate of the coastal zone, circulating pollutants, altering storms, changing temperature, and moving coastal currents affect air pollution and disaster preparedness, ocean pollution, and safeguarding near-shore ecosystems. Activities in commerce, industry, transportation, freshwater supply, safety, recreation, and national defense also are affected. The research community engaged in studies of coastal meteorology in recent years has made significant advancements in describing and predicting atmospheric properties along coasts. Coastal Meteorology reviews this progress and recommends research that would increase the value and application of what is known today.

Download or read book Coastal Marine Ecosystems of Latin America written by U. Seeliger and published by Springer Science & Business Media. This book was released on 2000-10-18 with total page 394 pages. Available in PDF, EPUB and Kindle. Book excerpt: Coastal and marine ecosystems, some severely degraded, other still pristine, control rich resources of inshore environments and coastal seas of Latin America's Pacific and Atlantic margins. Conflicts between the needs of the region's nations and diminishing revenues and environmental quality have induced awareness of coastal ecological problems and motivated financial support for restoration and management. The volume provides a competent review on the structure, processes and function of 22 important Latin American coastal marine ecosystems. Each contribution describes the environmental settings, biotic components and structure of the system, considers trophic processes and energy flow, evaluates the modifying influence of natural and human perturbations, and suggests management needs. Although the focus of the book is on basic ecological research, the results have application for coastal managers.
