Book excerpt: This study analyzed observational data from field programs in the Persian Gulf and off the coast of California; characterizing the spatial variability of marine atmospheric BL structure in the coastal environment, and the processes that control that structure. Significant results concern the scaling of turbulence under stable conditions - a commonly quoted form for the temperature scale is shown to be formally invalid. The spatial variability of radar propagation conditions over near-coastal waters has been shown to be significant, and the errors in propagation assessment resulting from a failure to account for this variability shown to be unacceptably large. The boundary-layer flow along the coasts of Oregon and northern California during summer are shown to be close to critical over very wide areas, and supercritical over significant regions around every major headland along the coast. The spatial variability of wind stress its curt is found to be large along the coast; the tatter is closely tied to sea surface temperature distributions through its modulation of cold upwelling. Stable conditions were widespread and persistent over the cold coastal waters; significant discrepancies between measured and parametrized fluxes were observed within the stable regions.

Download or read book The Benthic Boundary Layer written by Bernard P. Boudreau and published by Oxford University Press. This book was released on 2001-03-22 with total page 430 pages. Available in PDF, EPUB and Kindle. Book excerpt: The benthic boundary layer is the zone of water and sediment immediately adjacent to the bottom of a sea, lake, or river. This zone is of considerable interest to biologists, geochemists, sedimentologists, and engineers because of very strong gradients of energy, dissolved and solid chemical components, suspended matter, and the number of organisms that live there. It is, for example, the sink for anthropogenic substances and the home of microscopic plant life that provides the nutrients that determine fish populations--and ultimately the size of the fisheries. This book of original chapters edited by Professors Boudreau and Jorgensen, both leading researchers in the field, will meet the need for an up-to-date, definitive text/reference on measurements, techniques, and models for transport and biochemical processes in the benthic boundary layer. Each chapter provides a comprehensive review of a selected field, with illustrated examples from the authors' own work. The book will appeal to professionals and researchers in marine biology, marine chemistry, marine engineering, and sedimentology.
Download or read book Coastal Meteorology written by National Research Council and published by National Academies Press. This book was released on 1992-02-01 with total page 112 pages. 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 Bottom Boundary Layers and Sediment Transport written by Peter Nielsen and published by World Scientific. This book was released on 1992 with total page 356 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is intended as a useful handbook for professionals and researchers in the areas of Physical Oceanography, Marine Geology, Coastal Geomorphology and Coastal Engineering and as a text for graduate students in these fields. With its emphasis on boundary layer flow and basic sediment transport modelling, it is meant to help fill the gap between general hydrodynamic texts and descriptive texts on marine and coastal sedimentary processes. The book commences with a review of coastal bottom boundary layer flows including the boundary layer interaction between waves and steady currents. The concept of eddy viscosity for these flows is discussed in depth because of its relation to sediment diffusivity. The quasi-steady processes of sediment transport over flat beds are discussed. Small scale coastal bedforms and the corresponding hydraulic roughness are described. The motion of suspended sand particles is studied in detail with emphasis on the possible suspension maintaining mechanisms in coastal flows. Sediment pickup functions are provided for unsteady flows. A new combined convection-diffusion model is provided for suspended sediment distributions. Different methods of sediment transport model building are presented together with some classical models.

Available in PDF, EPUB and Kindle. Book excerpt: The world's coastlines represent a myriad of dynamic and constantly changing environments. Heavily settled and intensely used areas, they are of enormous importance to humans and understanding how they are shaped and change is crucial to our future. Introduction to Coastal Processes and Geomorphologybegins by discussing coastal systems and shows how these systems link to the processes examined in detail throughout the book. These include the morphodynamic paradigm, tides, waves and sediment transport. Later chapters explore fluvial deltas, estuaries, beaches and barriers, coastal sand dunes and geologically-influenced coasts such as cliffs, coral reefs and atolls. A new chapter addresses the forward-facing aspect of coastal morphodynamics, including the ways in which coasts respond to rapid climate changes such as present day global warming. Also new to this second edition is a chapter on future coasts which considers the wider effects of coastal change on other important aspects of coastal systems, including ecology, management, socio-cultural activities, built and natural heritage, and archaeology. Case studies using examples from around the world illustrate theory in practice and bring the subject to life. Each chapter starts by outlining the 'aims' and questions at the end allow you to track your progress.

Available in PDF, EPUB and Kindle. Book excerpt: On May 25, 1977 a small invited group of coastal oceanographers assembled at the Marine Sciences Research Center at Stony Brook for three days of intensive discussions in a cloistered setting. The purpose of this workshop was to "assess the state of the art, to ascertain priorities for future research and to formulate the theoretical, instrumen tal, experimental and logistical tools needed to attain those goals in the study of coastal oceanic* fronts. " Although the existence of oceanic fronts has been known for a long time, ocean frontology is experiencing rapid acceleration in the emergence of new concepts and methodology. The science is developing from the descriptive phase and many unsolved problems lie in the understanding and quantification of frontal dynamics. In turn, challenging questions need to be addressed on the controlling influence of the physics of fronts on the chemistry, biology, acoustics, and suspended particulate aggregations in these zones. Coastal fronts are very efficient at concentrating buoyant and suspended particulate matter inclUding toxic wastes; heavy metal concentrations in polluted coastal frontal zones have been measured to be as high as one to ten thousand times background. These zones are also regions of high biological productivity, and consequently frequented by both commercial and sports fishermen.
Download or read book The Marine Boundary Layer in the Vicinity of an Ocean Front written by David P. Rogers and published by . This book was released on 1989 with total page 20 pages. Available in PDF, EPUB and Kindle. Book excerpt: Aircraft observations obtained during the Frontal Air-Sea Interaction Experiment (FASINEX) are used to investigate the structure of the marine atmospheric boundary layer in the vicinity of an ocean front. A quasi-stationary sea surface temperature (STT) discontinuity of 2 C was maintained across the frontal zone throughout the duration of the experiment. The primary response of the atmosphere to changes in the SST was observed in the surface-related turbulence fluxes. In the case of warm air flowing over cold water, the boundary layer appears to develop an internal boundary layer (IBL) in response to the sudden change in the sea surface temperature. The organized updrafts and downdrafts within this layer collapse with entrainment-detrainment processes in these cells dominating the turbulence statistics. The IBL grows in response to the wind shear in this layer, although the surface shear stress is much smaller on the colder side of the front than on the warm. The depth of the IBL, and, in the absence of the IBL, the mixed layer are found to scale with the friction velocity and the Coriolis parameter. The IBL confines the surface-related turbulent mixing and shear-driven processes to the lower layers of the atmosphere. Thus, the shallow boundary layer cloud field appears to be maintained primarily by radiative transfer within the cloud layer. Multiple cloud-capped mixed layers were frequently observed throughout the experiment. They appear to be directly related to the horizontal variation of SST with deeper boundary layers and higher cloud levels formed over warmer water. Air water interactions; Reprints. (edc).

Download or read book Coastal Oceanography written by Tetsuo Yanagi and published by Springer. This book was released on 2000-03-31 with total page 164 pages. Available in PDF, EPUB and Kindle. Book excerpt: A coastal sea area usually indicates a sea area between a continental shelf break with a water depth of about 200 m and the land shore. About 70% of global fish resources spend part of their life cycle in the coastal seas, which accounts for 90% of marine biomass yield. Freshwater and nutrients from the land have a great influence on the coastal seas, especially since more than half the human population lives within 100 km of a coast. Chemical reactions occur there rapidly between substances from the land as they encounter substances from the ocean. In terms of physics, a coastal sea acts as a boundary layer and kinetic energy is actively exchanged there. But if coastal oceanography were to be summed up in a single sentence, it would be `the study that quantitatively makes clear the material transport in the coastal sea area'. Because the physical, chemical and biological processes relate to the material transport in the sea, it can be said the coastal oceanography is a genuinely interdisciplinary study. This book clarifies the quantitative material transport processes in the coastal sea area, mainly from a physical viewpoint.
Download or read book Coastal and Estuarine Processes written by Peter Nielsen and published by World Scientific Publishing Company. This book was released on 2009-04-21 with total page 360 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book covers water waves, surf zone hydrodynamics, tides in oceans and estuaries, storm surges, estuarine mixing, basic sediment transport, coastal morphodynamics and coastal groundwater dynamics. It is an introductory treatment, suitable for a first course in coastal and estuarine processes for earth scientists or engineers. Yet, there are substantial amounts of new material that are included, such as the explicit, analytical treatment of transient, forced long waves. Inclusion of this material will in turn strongly enhance the introductory treatment of tsunami, storm surges and surf beat. The treatment of sine wave theory emphasizes expressions which are explicit in the water depth h (using koh instead of kh) so that they can easily be differentiated or integrated with respect to h. This is a major pedagogical advantage because of the enhanced transparency. The treatment of turbulent mixing includes finite mixing length effects which provide an explanation for differential diffusion of different sediment sizes in suspension. The effects of acceleration skewness and boundary layer streaming are also included in the basic sediment transport models. The inclusion of beach groundwater dynamics — including the mechanisms by which waves as well as tides drive groundwater motion — provides a link between the previously unconnected fields of coastal hydraulics and regional groundwater modeling. Serving as a good reference book, it is fully indexed and comprehensively cross referenced. Abundant references to more detailed texts are also provided.
