This book was released on 2021 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The boundary current system in the Weddell Sea is composed of surface and gravity currents, which flow along the Antarctic margin's, south of the Atlantic basin. These currents are central for the meridional transfer of heat and bio-geochemical properties between the Weddell Sea and the world ocean. They contribute to the transport of relatively warm water towards the Weddell Sea continental shelves, a major site where cold and dense shelf water forms, and the export of dense shelf water towards lower latitudes, feeding the lower branch of the meridional overturning circulation. Yet, the link between warm water inflow and export of dense shelf water still needs to be made on seasonal-time scales. The goal of my PhD is to provide the first coherent description of the seasonal evolution of the boundary current system along the continental slope. Combining oceanographic data, I find a synchronised seasonality of the barotropic flow along the Weddell Sea's continental slope. The seasonal acceleration of the barotropic flow significantly contributes to the transport of dense shelf waters and correlates with the surface stress in the eastern side of the Weddell Sea. This finding suggests that the winds in the eastern Weddell Sea remotely contribute to the transport of dense shelf waters in the western Weddell Sea. How- ever, the mechanisms controlling the relationship between the surface stress and the barotropic flow remains unclear. Even though oceanographic data are generally insufficient to quantitatively compare the baroclinic variability along the continental slope, I observe a weakening of the baroclinic seasonality between the eastern and the western part of the continental slope. A conceptual model developed for this study supports an along-slope dampening of the baroclinic signals associated with (1) the presence of a density gradient between the dense shelf water on the south- and western continental shelves and the water masses on the continental slope and, (2) the widening of the continental slope between the eastern and southern Weddell Sea. The former implies the formation of eddies, which diffuses the seasonality along the continental shelf edge. The latter implies an along-slope decrease in flow strength, limiting the downstream advection of density anomalies from the eastern Weddell Sea. In the end, my analysis suggests that the region in front of the Ronne/Larsen Ice shelves in the southern/western Weddell Sea is less sensitive to the downstream advection of seasonal anomalies from the eastern Weddell Sea than the region in front of the Filchner Ice shelf in the southeastern Weddell Sea. However, data overlapping in time need to be collected in front of the eastern and the south-western continental shelves to quantify the downstream propagation of the baroclinic signals and corroborate this result.
Book Synopsis Ocean Circulation and Climate by : Shiro Imawaki
Download or read book Ocean Circulation and Climate written by Shiro Imawaki and published by Elsevier Inc. Chapters. This book was released on 2013-10-22 with total page 90 pages. Available in PDF, EPUB and Kindle. Book excerpt: Strong, persistent currents along the western boundaries of the world’s major ocean basins are called “western boundary currents” (WBCs). This chapter describes the structure and dynamics of WBCs, their roles in basin-scale circulation, regional variability, and their influence on atmosphere and climate. WBCs are largely a manifestation of wind-driven circulation; they compensate the meridional Sverdrup transport induced by the winds over the ocean interior. Some WBCs also play a role in the global thermohaline circulation, through inter-gyre and inter-basin water exchanges. After separation from the boundary, most WBCs have zonal extensions, which exhibit high eddy kinetic energy due to flow instabilities, and large surface fluxes of heat and carbon dioxide. The WBCs described here in detail are the Gulf Stream, Brazil and Malvinas Currents in the Atlantic, the Somali and Agulhas Currents in the Indian, and the Kuroshio and East Australian Current in the Pacific Ocean.

Book Synopsis Using R for Introductory Statistics by : John Verzani
Download or read book Using R for Introductory Statistics written by John Verzani and published by CRC Press. This book was released on 2018-10-03 with total page 522 pages. Available in PDF, EPUB and Kindle. Book excerpt: The second edition of a bestselling textbook, Using R for Introductory Statistics guides students through the basics of R, helping them overcome the sometimes steep learning curve. The author does this by breaking the material down into small, task-oriented steps. The second edition maintains the features that made the first edition so popular, while updating data, examples, and changes to R in line with the current version. See What’s New in the Second Edition: Increased emphasis on more idiomatic R provides a grounding in the functionality of base R. Discussions of the use of RStudio helps new R users avoid as many pitfalls as possible. Use of knitr package makes code easier to read and therefore easier to reason about. Additional information on computer-intensive approaches motivates the traditional approach. Updated examples and data make the information current and topical. The book has an accompanying package, UsingR, available from CRAN, R’s repository of user-contributed packages. The package contains the data sets mentioned in the text (data(package="UsingR")), answers to selected problems (answers()), a few demonstrations (demo()), the errata (errata()), and sample code from the text. The topics of this text line up closely with traditional teaching progression; however, the book also highlights computer-intensive approaches to motivate the more traditional approach. The authors emphasize realistic data and examples and rely on visualization techniques to gather insight. They introduce statistics and R seamlessly, giving students the tools they need to use R and the information they need to navigate the sometimes complex world of statistical computing.

This book was released on 2017-08-07 with total page 552 pages. Available in PDF, EPUB and Kindle. Book excerpt: Quaternary Paleoenvironments examines the drowned landscapes exposed as extensive and attractive territory for prehistoric human settlement during the Ice Ages of the Pleistocene, when sea levels dropped to 120m-135m below their current levels. This volume provides an overview of the geological, geomorphological, climatic and sea-level history of the European continental shelf as a whole, as well as a series of detailed regional reviews for each of the major sea basins. The nature and variable attractions of the landscapes and resources available for human exploitation are examined, as are the conditions under which archaeological sites and landscape features are likely to have been preserved, destroyed or buried by sediment during sea-level rise. The authors also discuss the extent to which we can predict where to look for drowned landscapes with the greatest chance of success, with frequent reference to examples of preserved prehistoric sites in different submerged environments. Quaternary Paleoenvironments will be of interest to archaeologists, geologists, marine scientists, palaeoanthropologists, cultural heritage managers, geographers, and all those with an interest in the drowned landscapes of the continental shelf.

Book Synopsis Leading at the Edge by : Dennis N.T. Perkins
Download or read book Leading at the Edge written by Dennis N.T. Perkins and published by HarperChristian + ORM. This book was released on 2012-03-28 with total page 277 pages. Available in PDF, EPUB and Kindle. Book excerpt: Drawing on the amazing story of Shackleton and his polar exploration team’s survival against all odds, author Dennis N. T. Perkins demonstrates the importance of a strong leader in times of adversity, uncertainty, and change. Part adventure tale and part leadership guide, Leading at the Edge uncovers what the legendary Antarctic adventure of Sir Ernest Shackleton, his ship Endurance, and his team of twenty-seven polar explorers can teach us about bringing order to chaos through true leadership. Among other skills, you’ll learn how to: instill optimism while staying grounded in reality, step up to risks worth taking, consistently reinforce your team message, set a personal example, find things to celebrate, laugh small things off, and--even in the face of extreme temperatures, hazardous ice, scarce food, and complete isolation--never give up. This second edition of Leading at the Edge features additional lessons, new case studies of the strategies in action, tools to uncover and resolve conflicts, and expanded resources. An updated epilogue compares the leadership styles of the famous polar explorers Shackleton, Amundsen, and Scott, which transcend the one-hundred-plus years since their historic race to the South Pole to help today’s leaders learn valuable lessons about the meaning of true success.
Book Synopsis Marine Mammal Welfare by : Andy Butterworth
Download or read book Marine Mammal Welfare written by Andy Butterworth and published by Springer. This book was released on 2017-06-19 with total page 625 pages. Available in PDF, EPUB and Kindle. Book excerpt: Marine mammals attract human interest – sometimes this interest is benign or positive – whale watching, conservation programmes for whales, seals, otters, and efforts to clear beaches of marine debris are seen as proactive steps to support these animals. However, there are many forces operating to affect adversely the lives of whales, seals, manatees, otters and polar bears – and this book explores how the welfare of marine mammals has been affected and how they have adapted, moved, responded and sometimes suffered as a result of the changing marine and human world around them. Marine mammal welfare addresses the welfare effects of marine debris, of human traffic in the oceans, of noise, of hunting, of whale watching and tourism, and of some of the less obvious impacts on marine mammals – on their social structures, on their behaviours and migration, and also of the effects on captivity for animals kept in zoos and aquaria. There is much to think and talk about – how marine mammals respond in a world dramatically influenced by man, how are their social structures affected and how is their welfare impacted?

Book Synopsis Analytic Methods of Sound Field Synthesis by : Jens Ahrens
Download or read book Analytic Methods of Sound Field Synthesis written by Jens Ahrens and published by Springer Science & Business Media. This book was released on 2012-01-25 with total page 308 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book puts the focus on serving human listeners in the sound field synthesis although the approach can be also exploited in other applications such as underwater acoustics or ultrasonics. The author derives a fundamental formulation based on standard integral equations and the single-layer potential approach is identified as a useful tool in order to derive a general solution. He also proposes extensions to the single-layer potential approach which allow for a derivation of explicit solutions for circular, planar, and linear distributions of secondary sources. Based on above described formulation it is shown that the two established analytical approaches of Wave Field Synthesis and Near-field Compensated Higher Order Ambisonics constitute specific solutions to the general problem which are covered by the single-layer potential solution and its extensions.
