Book excerpt: Das Buch enthält insgesamt 33 Vorträge, die anlässlich des Symposiums "Measuring, Modeling, Predicting, and Applying Directional Ocean Wave Spectra" gehalten wurden, welches von 19890418 bis 19890420 am Applied Physics Laboratory der Johns Hopkins Universität stattfand. Das Symposium war den Ergebnissen des Labrador Sea Extreme Waves Experiment (LEWEX) gewidmet, welches mit internationaler Beteiligung unter Einsatz von zwei Schiffen, zwei Radar- Fernerkundungsflugzeugen sowie Radar-Fernerkundungssatelliten im März 1987 in der Labradorsee durchgeführt wurde. Ziel war die Bestimmung von richtungsbezogenen Meereswellenspektren. Nach zwei einführenden Vorträgen in das Experiment LEWEX sowie in die Bedeutung der Wellenspektren widmen sich die übrigen Fachbeiträge folgenden Themen: Physik von Wind und Wellen (Wind-Wave Physics); Seegangsverhalten und Messungen an der Meeresoberfläche (Seakeeping and Surface Measurement); Luftgestützte und weltraumgestützte Radarmessungen (Air and Space Measurement); Numerische Modellrechnungen (Numerical Model Estimates); Zukünftiger Forschungsbedarf (Future Directions). 300 der während LEWEX gemessenen 2000 Wellenspektren werden vorgestellt und verglichen.

Available in PDF, EPUB and Kindle. Book excerpt: During the past decade, man's centuries-old interest in marine me teorology and oceanography has broadened. Ocean and atmosphere are now treated as coupled parts of one system; the resulting interest in air-sea interaction problems has led to a rapid growth in the sophistication of instruments and measurement techniques. This book has been designed as a reference text which describes, albng with the instruments themselves, the accumulated practical experi ence of experts engaged in field observations of air-sea interac tions. It is meant to supplement rather than replace manuals on standard routine observations or instnunentation handbooks. At the inception a textbook was planned, which would contain only well tested methods and instruments. It was quickly discovered that for the book to be useful many devices and techniques would have to be included which are still evolving rapidly. The reader is therefore cautioned to take nothing in these pages for granted. Certainly, every contributor is an expert, but while some are back ed up by generations of published work, others are pioneers. The choice of topics, of course, is debatable. The types of observa tions included are not exhaustive and topics such as marine aero sols and radio-tracers are omitted, as was the general subject of remote sensing, which was felt to be too broad and evol ving too rapidly. The guideline adopted in limiting size was maximum use fulness to 'a trained experimentalist new to the field'.

Download or read book Estimation of Directional Surface Wave Spectra from a Towed Research Catamaran written by and published by . This book was released on 1997 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: During the High Resolution Remote Sensing Main Experiment, wave height was estimated from a moving catamaran using pitch rate and roll rate sensors, a three axis accelerometer, and a capacitive wave wire. The wave spectrum in the frequency band ranging roughly from 0.08 Hz to 0.3 Hz was verified by independent buoy measurements. To estimate the directional frequency spectrum from a wave-wire array the Data Adaptive Spectral Estimator is extended to include the Doppler shifting effects of a moving platform. The method is applied to data obtained from a fixed platform during the Ris0 Air Sea Experiment, and data obtained from a moving platform during the Coastal Ocean Processes Experiment. Both results show that the propagation direction of the peak wind waves compares well with the measured wind direction. When swells and local wind waves are not aligned, the method can resolve the difference of propagation directions. Using the fixed platform data a numerical test is conducted which shows that the method is able to distinguish two wave systems propagating at the same frequency but in two different directions.

Download or read book Waves in Oceanic and Coastal Waters written by Leo H. Holthuijsen and published by Cambridge University Press. This book was released on 2010-02-04 with total page 9 pages. Available in PDF, EPUB and Kindle. Book excerpt: Waves in Oceanic and Coastal Waters describes the observation, analysis and prediction of wind-generated waves in the open ocean, in shelf seas, and in coastal regions with islands, channels, tidal flats and inlets, estuaries, fjords and lagoons. Most of this richly illustrated book is devoted to the physical aspects of waves. After introducing observation techniques for waves, both at sea and from space, the book defines the parameters that characterise waves. Using basic statistical and physical concepts, the author discusses the prediction of waves in oceanic and coastal waters, first in terms of generalised observations, and then in terms of the more theoretical framework of the spectral energy balance. He gives the results of established theories and also the direction in which research is developing. The book ends with a description of SWAN (Simulating Waves Nearshore), the preferred computer model of the engineering community for predicting waves in coastal waters.

Book excerpt: Maritime Technology and Engineering 3 is a collection of papers presented at the 3rd International Conference on Maritime Technology and Engineering (MARTECH 2016, Lisbon, Portugal, 4-6 July 2016). The MARTECH Conferences series evolved from biannual national conferences in Portugal, thus reflecting the internationalization of the maritime sector. The keynote lectures and the papers, making up nearly 150 contributions, came from an international group of authors focused on different subjects in a variety of fields: Maritime Transportation, Energy Efficiency, Ships in Ports, Ship Hydrodynamics, Ship Structures, Ship Design, Ship Machinery, Shipyard Technology, afety & Reliability, Fisheries, Oil & Gas, Marine Environment, Renewable Energy and Coastal Structures. Maritime Technology and Engineering 3 will appeal to academics, engineers and professionals interested or involved in these fields.
