This book was released on 2012-12-06 with total page 750 pages. Available in PDF, EPUB and Kindle. Book excerpt: To place this book in perspective it is useful for the reader to be aware of the recent history of the topic of underwater sound generation at the ocean surface by natural mechanisms. A meeting in Lerici, Italy in 1987 was convened within the NATO Advanced Research Workshop series, to bring together underwater acousticians and ocean hydrodynamicists to examine various mechanisms which generate sound naturally at the ocean surface. A record of that meeting was published in the NATO scientific publication series in 1988 under the title 'Sea Surface Sound'. That meeting was successful in inspiring and co ordinating both participants and non-attending colleagues to examine some key issues which were raised during the course of presentations and discussions. The understanding among those present was that another meeting should be convened 3 years hence to report and review progress in the subject. Accordingly the second conference was convened in Cambridge in 1990, whose proceedings are presented here. This volume represents a very gratifying increase in only a 3 year interval in our understanding of a number of physical processes which generate sound at the peripheries of oceans. In fact it represents both the acceleration of singular effort as well as the development of interdisciplinary sophistication and co-operation. The enthusiasm, goodwill, and intense scientific curiosity which characterized the Lerici meeting carried through to Cambridge. The collegial atmosphere established by the participants was perfectly timed to foster another major advance in studies of ocean surface sound.
Book Synopsis Wind Waves in Sea Ice of the Western Arctic and a Global Coupled Wave-ice Model by : Vincent T. Cooper

This book was released on 2022 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The retreat of Arctic sea ice is enabling increased ocean wave activity at the ice edge, yet the interactions between surface waves and sea ice are not fully understood. Here, we examine in situ observations of wave spectra spanning 2012-2021 in the western Arctic marginal ice zone (MIZ). Swell waves are rarely observed beyond 100 km inside the MIZ. However, local wind waves are observed forming in patches of open water amid partial ice cover during summer. These local waves remain fetch-limited between ice floes with heights less than 1 m. To investigate the physics of these waves, we conduct experiments varying wave attenuation and generation in ice in a global model with coupled interactions between waves and sea ice. A weak high-frequency attenuation rate is required to simulate the wind waves reported in observations. The choice of attenuation scheme and the wind input in ice have a remarkable impact on the extent of wave activity in sea ice across polar oceans, particularly in the Southern Hemisphere. As well as demonstrating the need for stronger constraints on wave attenuation, our results suggest further attention should be paid to locally generated wind waves and their role in sea ice evolution.

This book was released on 2012-12-06 with total page 730 pages. Available in PDF, EPUB and Kindle. Book excerpt: The comprehensive research activity around the World in the fields of Underwater Acoustics and Signal Processing being strongly supported by new experimental technique and equipment and by the parallel fast developments in computer technology and solid state devices, which has led to a rapidly reducing cost of digital processing thus enabling more complex processing to be carried out economically, emphasize how necessary it is at intervals of a few years through a NATO Advanced Study Institute (NATO ASI) and guided by leading experts to study the conquests in the fields of Underwater Acoustics and Signal Processing. This need of study is moreover stressed by the interdisciplina rity of Underwater Acoustics and Signal Processing, where a strong impact from other branches of science, - Geophysics, Radioastronomy, Bioengineering, Telecommunication, Seismology, Space Research etc. - is taking place, which makes it an extre mely difficult task for scientists to follow-up the development in all its phases and to preserve the general view of its rapid ly increasing number of possibilities. The present Proceedings of the NATO ASI held in Copenhagen during August 1980 join the series of proceedings of NATO summer schools on Underwater Acoustics and Signal Processing held during the past 20 years. The equality and the fusion of the individual research fields of Underwater Acoustics and Signal Processing and the separate introduction of advanced research results from other scientific areas related to underwater acoustics such as transducers characterize the subject matter of this NATO ASI.

Book Synopsis Governance of Arctic Shipping by : Aldo Chircop
Download or read book Governance of Arctic Shipping written by Aldo Chircop and published by Springer Nature. This book was released on 2020-08-11 with total page 320 pages. Available in PDF, EPUB and Kindle. Book excerpt: This open access book is a result of the Dalhousie-led research project Safe Navigation and Environment Protection, supported by a grant from the Ocean Frontier Institute’s the Canada First Research Excellent Fund (CFREF). The book focuses on Arctic shipping and investigates how ocean change and anthropogenic impacts affect our understanding of risk, policy, management and regulation for safe navigation, environment protection, conflict management between ocean uses, and protection of Indigenous peoples’ interests. A rapidly changing Arctic as a result of climate change and ice loss is rendering the North more accessible, providing new opportunities while producing impacts on the Arctic. The book explores ideas for enhanced governance of Arctic shipping through risk-based planning, marine spatial planning and scaling up shipping standards for safety, environment protection and public health.

This book was released on 2021 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Marginal Ice Zone (MIZ) is a highly dynamic region between the open ocean and the inner ice pack. The ice over this region is subjected to waves, introducing new forces but also changing the ice from a cohesive material to a mobile collection of floes. Until recently, the challenges posed by in-situ ice measurements in the MIZ prevented a detailed characterization of changes in the ice cover. The rapidly changing conditions over short distances have also prevented detailed numerical simulations. Recent developments in observational and computational capabilities allow further investigations of the physical processes for ice formation and wave-ice interactions in the MIZ. Many features of the MIZ remain to be explained and quantified, particularly rapid ice movement near the ice edge and ice thickening under wave pressure. In order to investigate these and support future field and numerical studies, a model of the MIZ is developed with a new numerical method better suited for high resolution. Simulations of waves causing ice compaction and the ice edge jet are then performed to detail the expected impacts of waves on sea ice. The potential of numerical improvements in sea ice models to obtain greater efficiency and accuracy at high resolutions is successfully demonstrated. The addition of the wave radiative stress allows the generation of realistic thickness profiles, provided that the sea ice strength is modified to represent the difference between pack ice and thinner ice. With the same modifications, obliquely incident waves on the ice edge produced an ice edge jet with a range of characteristics depending on wave parameters and modeled interactions. The magnitude of wave attenuation in sea ice and the ice strength are found to be very important factors in the simulations. Consideration of wave effects on ice thickness and drift speed are also shown to have potential to increase both open water and ice formation.

Download or read book Air-Ice-Ocean Interaction written by Miles McPhee and published by Springer Science & Business Media. This book was released on 2008-06-04 with total page 218 pages. Available in PDF, EPUB and Kindle. Book excerpt: At a time when the polar regions are undergoing rapid and unprecedented change, understanding exchanges of momentum, heat and salt at the ice-ocean interface is critical for realistically predicting the future state of sea ice. By offering a measurement platform largely unaffected by surface waves, drifting sea ice provides a unique laboratory for studying aspects of geophysical boundary layer flows that are extremely difficult to measure elsewhere. This book draws on both extensive observations and theoretical principles to develop a concise description of the impact of stress, rotation, and buoyancy on the turbulence scales that control exchanges between the atmosphere and underlying ocean when sea ice is present. Several interesting and unique observational data sets are used to illustrate different aspects of ice-ocean interaction ranging from the impact of salt on melting in the Greenland Sea marginal ice zone, to how nonlinearities in the equation of state for seawater affect mixing in the Weddell Sea. The book’s content, developed from a series of lectures, may be appropriate additional material for upper-level undergraduates and first-year graduate students studying the geophysics of sea ice and planetary boundary layers.
