This book was released on 2006-01-08 with total page 53 pages. Available in PDF, EPUB and Kindle. Book excerpt: The age and condition of the U.S. Coast Guard's polar icebreakers are jeopardizing national security and scientific research in the Arctic and Antarctic, according to an interim report from the National Academies. Because of a shortfall in funding for U.S. polar icebreaking activities, long-term maintenance on these icebreakers has been deferred over the past several years, making the ships inefficient to operate and their technological systems outdated. Congress asked the National Academies to provide a comprehensive assessment of the current and future roles of U.S. Coast Guard polar icebreakers in supporting U.S. operations in the Antarctic and the Arctic, including scenarios for continuing those operations and alternative approaches, the changes in roles and missions of polar icebreakers in the support of all national priorities in the polar regions, and potential changes in the roles of U.S Coast Guard icebreakers in the Arctic that may develop due to environmental change. This brief interim report highlights the most urgent and time-dependent issues, and a final report, expected to be released next summer, will examine the type and number of icebreaking ships that the U.S. requires in the long term and other issues.

This book was released on 2007-03-14 with total page 135 pages. Available in PDF, EPUB and Kindle. Book excerpt: The United States has enduring national and strategic interests in the polar regions, including citizens living above the Arctic circle and three year-round scientific stations in the Antarctic. Polar icebreaking ships are needed to access both regions. Over the past several decades, the U.S. government has supported a fleet of four icebreakersâ€"three multi-mission U.S. Coast Guard ships (the POLAR SEA, POLAR STAR, and HEALY) and the National Science Foundation's PALMER, which is dedicated solely to scientific research. Today, the POLAR STAR and the POLAR SEA are at the end of their service lives, and a lack of funds and no plans for an extension of the program has put U.S. icebreaking capability at risk. This report concludes that the United States should continue to support its interests in the Arctic and Antarctic for multiple missions, including maintaining leadership in polar science. The report recommends that the United States immediately program, budget, design, and construct two new polar icebreakers to be operated by the U.S. Coast Guard. The POLAR SEA should remain mission capable and the POLAR STAR should remain available for reactivation until the new polar icebreakers enter service. The U.S. Coast Guard should be provided sufficient operations and maintenance budget to support an increased, regular, and influential presence in the Arctic, with support from other agencies. The report also calls for a Presidential Decision Directive to clearly align agency responsibilities and budgetary authorities.

Download or read book Commercial Ship Surveying written by Harry Karanassos and published by Butterworth-Heinemann. This book was released on 2015-11-26 with total page 302 pages. Available in PDF, EPUB and Kindle. Book excerpt: Commercial Ship Surveying: On/Off Hire Condition Surveys and Bunker Surveys provides guidance on the complete survey process, what should be done to prepare, and what constitutes good practice, all completely detailed so that the process can be executed quickly and efficiently. In addition to the surveying process, the book describes supplementary topics, such as the vessels likely encountered, the gear and rigging involved, and the special techniques necessary. The book is well-researched, with plenty of practical examples and photographic references, explaining not only what is expected to happen during surveys, but also how marine surveyors and ships’ officers are expected to perform, if, and when, they become involved with this work. Dedicated to detail, this book ensures that the reader clearly understands each step of the surveying process. Presents the first work to comprehensively describe the processes of on-hire, off-hire, and bunker surveys for dry cargo ships Includes a companion site featuring survey checklists and Excel worksheets for select calculations (such as heavy fuel and diesel oil weight calculations) Contains accompanying illustrations and photographs to clarify key concepts

This book was released on 2017-04-24 with total page 83 pages. Available in PDF, EPUB and Kindle. Book excerpt: The sea ice surrounding Antarctica has increased in extent and concentration from the late 1970s, when satellite-based measurements began, until 2015. Although this increasing trend is modest, it is surprising given the overall warming of the global climate and the region. Indeed, climate models, which incorporate our best understanding of the processes affecting the region, generally simulate a decrease in sea ice. Moreover, sea ice in the Arctic has exhibited pronounced declines over the same period, consistent with global climate model simulations. For these reasons, the behavior of Antarctic sea ice has presented a conundrum for global climate change science. The National Academies of Sciences, Engineering, and Medicine held a workshop in January 2016, to bring together scientists with different sets of expertise and perspectives to further explore potential mechanisms driving the evolution of recent Antarctic sea ice variability and to discuss ways to advance understanding of Antarctic sea ice and its relationship to the broader ocean-climate system. This publication summarizes the presentations and discussions from the workshop.
