This book was released on 2019 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Surface waves play an important role in how energy is transported and distributed to both sea ice and atmosphere in Arctic seas. The region of marginal sea ice, termed the Marginal Ice Zone (MIZ), has been increasing alongside temperature, introducing even more open water spaces within the sea ice field. Little research has focused on the development of waves within these open water spaces, and how the wave field evolves under such restricted fetch environments. This study considers a set of observations collected using moorings from ASL Environmental Sciences in the southern Beaufort Sea. These observations suggest local wave development as the dominant source of wave energy tens of kilometers in the MIZ throughout the month of August. The significant wave heights (H_s) and peak periods (T_p) were kept low throughout the month, mainly remaining below a H_s of 0.6 m and a T_p of 6 s in sea ice. At the end of the month, open water waves were able to influence the wave characteristics and there were notable increases in both heights and periods. This study examines how the attenuation of such waves by sea ice differs from the attenuation of open water waves moving into the MIZ. The coherence and positive correlation between H_s and T_p were found to be predominant in the sea ice field. This differs from the classic attenuation of open water waves in sea ice where peak periods increase while wave heights decrease, producing a distinct negative relationship with distance in sea ice. There was no preferential increase or lengthening of the dominant waves under easterly and southerly winds where the wave fetches were long, and the wind speed was found to have limited influence on wave growth after development. Estimations of fetch using empirical relationships, supplemented by satellite imagery, indicate that the short fetches were the dominant factor in terms of wave growth, which indicates an evolution similar to open water waves until they reach an sea ice floe interface and are scattered, a process which depends greatly on the sea ice type, size, rheology and the length of the waves. The interplay among the sea ice (size, structure and concentration) and the wind during a storm event provides an interesting look at the behavior of locally developed waves and the transition to more open water characteristics and development as the sea ice becomes eroded close to the end of the month. While waves developed locally in sea ice are expected to be fairly low compared to open water waves, they play an important role in the fluxes of energy and momentum in the MIZ and the expansion of this region has implications for the overall energy balance in Arctic marine systems.

Book excerpt: The Alaskan Beaufort Sea: Ecosystems and Environments provides an interdisciplinary view into almost all aspects of the environment, with a detailed survey of the background literature. This book focuses on the Alaskan Beaufort Shelf environment. Organized into four parts encompassing 20 chapters, this book begins with an overview of the characteristics and history of the region in which the research took place and defines the objectives of the studies program. This text then examines the subsynoptic meteorological networks along the Beaufort Sea coast and shelf. Other chapters consider the thermally generated mesoscale effects on surface winds and the orographic mesoscale effects on surface winds. This book discusses as well the phytoplankton associations and relative phytoplankton production in the area between the 20-m depth contour and the edge of the ice in summer. The final chapter deals with the characteristics of the ice cover and oil-ice interactions that will affect cleanup activities after blowout. This book is a valuable resource for scientists and conservationists.

Book excerpt: "The objective of this study was to produce, via hindcasting, a climatology for extreme storm waves in the Beaufort Sea, to be used as a reference for design considerations of offshore structures. Phase 1 of this study was aimed at reviewing previous environmental studies for the Beaufort region, and establishing an appropriate procedure to provide the design reference information, selecting an appropriate spectral wave model, selecting severe storms affecting the Canadian Beaufort Sea region, and evaluation of model hindcasts. Phase II of the study consisted of the final selection of the top severe storm population, hindcast production, extremal analysis, treatment of ice edge and presentation of final results. Already at the outset, it was realized that considerable effort would be required in order to provide adequate overwater wind fields and specification of the effects of sea ice and shallow water. Compared to previous studies with similar objectives for other areas such as the Canadian East and West Coasts or the Gulf of St. Lawrence, the number of available marine observations of weather and sea state from ships and rigs in the Beaufort is relatively small. The selection and hindcast of the potential severe storms is further complicated by the existence of sea ice. Extra care must therefore be taken when determining the wind and ice fields. Due to the special operating conditions in the Beaufort Sea, where drilling is mostly carried out on structures which differ from those used elsewhere, different considerations must be taken for establishing design criteria and critical conditions, and when selecting severe storm events for hindcasting. Some effort was therefore put into estimating which storms were likely to generate extreme currents, for example, as these would likely increase the potential for erosion of artificial islands"--Leaf 1-1.

Download or read book Wind Generated Ocean Waves written by I.R. Young and published by Elsevier. This book was released on 1999-03-23 with total page 307 pages. Available in PDF, EPUB and Kindle. Book excerpt: The goals of wind wave research are relatively well defined: to be able to predict the wind wave field and its effect on the environment. That environment could be natural (beaches, the atmosphere etc.) or imposed by human endeavour (ports, harbours, coastal settlements etc.). Although the goals are similar, the specific requirements of these various fields differ considerably.This book attempts to summarise the current state of this knowledge and to place this understanding into a common frame work. It attempts to take a balanced approach between the pragmatic engineering view of requiring a short term result and the scientific quest for detailed understanding. Thus, it attempts to provide a rigorous description of the physical processes involved as well as practical predictive tools.

Available in PDF, EPUB and Kindle. Book excerpt: Only a few centuries ago, we knew very little about our planet Earth. The Earth was considered flat by many although it was postulated by a few like Aristotle that it is spherical based on observations that included the study of lunar eclipses. Much later, Christopher Columbus successfully sailed to the West to discover the New World and Ferdinand Magellan’s ship circumnavigated the globe to prove once and for all that the Earth is indeed a sphere. Worldwide navigation and explorations that followed made it clear that the Earth is huge and rather impossible to study solely by foot or by water. The advent of air travel made it a lot easier to do exploratory studies and enabled the mapping of the boundaries of continents and the oceans. But aircraft coverage was limited and it was not until the satellite era that full c- erage of the Earth’s surface became available. Many of the early satellites were research satellites and that meant in part the development of engineering measurement systems with no definite applications in mind. The Nimbus-5 Electrically Scanning Microwave Radiometer (ESMR) was a classic case in point. The sensor was built with the idea that it may be useful for meteorological research and especially rainfall studies over the oceans, but success in this area of study was very limited.

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.

This book was released on 2014-08-01 with total page 343 pages. Available in PDF, EPUB and Kindle. Book excerpt: U.S. Arctic waters north of the Bering Strait and west of the Canadian border encompass a vast area that is usually ice covered for much of the year, but is increasingly experiencing longer periods and larger areas of open water due to climate change. Sparsely inhabited with a wide variety of ecosystems found nowhere else, this region is vulnerable to damage from human activities. As oil and gas, shipping, and tourism activities increase, the possibilities of an oil spill also increase. How can we best prepare to respond to such an event in this challenging environment? Responding to Oil Spills in the U.S. Arctic Marine Environment reviews the current state of the science regarding oil spill response and environmental assessment in the Arctic region north of the Bering Strait, with emphasis on the potential impacts in U.S. waters. This report describes the unique ecosystems and environment of the Arctic and makes recommendations to provide an effective response effort in these challenging conditions. According to Responding to Oil Spills in the U.S. Arctic Marine Environment, a full range of proven oil spill response technologies is needed in order to minimize the impacts on people and sensitive ecosystems. This report identifies key oil spill research priorities, critical data and monitoring needs, mitigation strategies, and important operational and logistical issues. The Arctic acts as an integrating, regulating, and mediating component of the physical, atmospheric and cryospheric systems that govern life on Earth. Not only does the Arctic serve as regulator of many of the Earth's large-scale systems and processes, but it is also an area where choices made have substantial impact on life and choices everywhere on planet Earth. This report's recommendations will assist environmentalists, industry, state and local policymakers, and anyone interested in the future of this special region to preserve and protect it from damaging oil spills.
