Far from land : the mysterious lives of seabirds
The lives and activities of seabirds as you've never seen them before Seabirds evoke the spirit of the earth's wildest places. They spend large portions of their lives at sea, often far from land, and nest on beautiful and remote islands that humans rarely visit. Thanks to the development of increasingly sophisticated and miniaturized devices that can track their every movement and behavior, it is now possible to observe the mysterious lives of these remarkable creatures as never before. This beautifully illustrated book takes you on a breathtaking journey around the globe to reveal where these birds actually go when they roam the sea, the tactics they employ to traverse vast tracts of ocean, the strategies they use to evade threats, and more. Michael Brooke has visited every corner of the world in his lifelong pursuit of seabirds. Here, he draws on his own experiences and insights as well as the latest cutting-edge science to shed light on the elusive seafaring lives of albatrosses, frigatebirds, cormorants, and other ocean wanderers. Where do puffins go in the winter? How deep do penguins dive? From how far away can an albatross spot a fishing vessel worth following for its next meal? Brooke addresses these and other questions in this delightful book. Along the way, he reveals that seabirds are not the aimless wind-tossed creatures they may appear to be and explains the observational innovations that are driving this exciting area of research. Featuring illustrations by renowned artist Bruce Pearson and packed with intriguing facts, Far from Land provides an extraordinary up-close look at the activities of seabirds.-- Source other than Library of Congress.

Major Law and Policy Issues in the South China Sea
Major law and policy issues in the South China Sea are discussed mainly from the perspectives of leading American and European scholars in the study of the complex South China Sea disputes. The issues include regional maritime cooperation and regime building, Southeast Asian countries' responses to the Chinese assertiveness, China's historic claims, maritime boundary delimitation and excessive maritime claims, military activities and the law of the sea, freedom of navigation and its impact on the problem, the dispute between Vietnam and China, confidence-building measures and U.S.-Taiwan-China relations in the South China Sea, and Taiwan's role in the resolution to the South China Sea issues. Over the past three years, there have been several incidents in the South China Sea between the claimants, and also between the claimants and non-claimants over fisheries, collection of seismic data, exploration for oil and gas resources, and exercise of freedom of navigation. Third party concerns and involvement in the South China Sea disputes have been increasing as manifested in actions taken by the United States, India, and Japan. It is therefore important to examine South China Sea disputes from the legal and political perspective and from the view point of American and European experts who have been studying South China Sea issues for many years.

China’s Naval Operations in the South China Sea
China’s Naval Operations in the South China Sea is highly topical; it examines the evolving perception of the People’s Republic of China’s (PRC) of the South China Sea (SCS), and Beijing’s accompanying maritime strategy to claim the islands and waters, particularly in the context of the strategies of the neighbouring stake-holding nations. In addition to long-standing territorial disputes over the islands and waters of the SCS, China and the other littoral states — Vietnam, the Philippines, Brunei, Malaysia, Taiwan, and Indonesia — have growing and often mutually exclusive interests in the offshore energy reserves and fishing grounds. Many other countries outside of the region worry about the protection of sea lines of communication for military and commercial traffic, oil tankers in particular. These differences have been expressed in the increasing frequency and intensity of maritime incidents, involving both naval and civilian vessels, sometimes working in coordination against naval or civilian targets. Each chapter on the littoral states closely examines that state’s territorial claims to the islands and waters of the SCS, its primary economic and military interests in these areas, its views on the sovereignty disputes over the entire SCS, its strategy to achieve its objectives, and its views on the U.S. involvement in any and all of these issues.

Synchronous Variation Patterns of Monthly Sea Ice Anomalies at the Arctic and Antarctic
Sea ice variability in the opposite polar regions is examined holistically by applying the self-organizing map (SOM) method to global monthly sea ice concentration data over two periods. The results show that the variability modes of sea ice decrease in the Arctic correspond to an overall sea ice increase in the Antarctic, and vice versa. In particular, the monthly sea ice anomaly patterns are dominated by in-phase variability across the Arctic that is stronger in the marginal seas particularly the Barents Sea than the central Arctic Ocean. The corresponding Antarctic sea ice variability is characterized by a zonal wavenumber-3 structure or a dipole pattern of out-of-phase variability between the Bellingshausen/Amundsen Seas and the rest of the Southern Ocean. The frequency of occurrence of these dominant patterns exhibits pronounced seasonal as well as decadal variability and the latter is closely related to the Pacific decadal oscillation and Atlantic multidecadal oscillation. Other less frequent patterns seem to be associated with the central Pacific ElNi˜no and spatially heterogeneous interannual variability of sea surface temperature (SST) in the Indian and the Atlantic Oceans. The dominant modes explain 57% of the four-decade domain-averaged trends in the annual polar sea ice concentration, with more explained in the eastern than western Arctic Ocean and in the Weddell Sea and the Amundsen Sea in the Antarctic. The spatial patterns of the leading modes can be largely explained by the dynamic (sea ice drift) and thermodynamic (sea ice melt) effects of the anomalous atmospheric circulations associated with SST and sea level pressure anomalies.

Causes and impacts of sea ice variability in the sea of Okhotsk using CESM-LE
This study provides a holistic view of the coupled ocean-atmosphere-sea ice processes responsible for generating interannual variability in sea ice coverage in the Sea of Okhotsk as well as the atmospheric response to this variability. Simulations from the Community Earth System Model Large Ensemble project are analyzed, providing the ability to elucidate the time evolution of these relationships through weekly lead-lag composite analysis, while maintaining a large number of samples to provide robust conclusions. We find that thermodynamic processes involving anomalous ocean-atmosphere heat fluxes affect the timing of initial sea ice growth in the Sea of Okhotsk as early as November. Low-level wind anomalies in the winter affect the extent to which sea ice fully develops, both through advection of the sea ice itself and through changes in the transport of air masses over the Sea of Okhotsk. In this study, the results synthesize and support a diverse set of mechanisms identified in previous observational studies to be responsible for anomalous sea ice conditions, but in a coupled global climate model framework with a large sample size. We also find evidence that anomalous ocean-atmosphere heat fluxes in the winter can trigger an atmospheric response comprised of a local negative sea-level pressure anomaly and Rossby wave that extends over North America. The sign of the turbulent heat fluxes relative to the sea ice anomalies confirm that this is indeed a lagged response of the atmosphere forced by sea ice anomalies. This validates the Rossby wave train response identified in more idealized model simulations with prescribed sea ice and sea surface temperature by demonstrating that this process also occurs in a more realistic coupled model framework.

The seabird's cry : the lives and loves of the planet's great ocean voyagers
\"Even as we are coming to understand them, the number of seabirds on our planet is in freefall, dropping by nearly 70% in the last sixty years, a billion fewer now than there were in 1950. Of the ten birds in this book, seven are in decline, at least in part of their range. Extinction stalks the ocean and there is a danger that the grand cry of the seabird colony, rolling around the bays and headlands of high latitudes, will this century become little but a memory ... Over the last couple of decades, modern science has begun to understand their epic voyages, their astonishing abilities to navigate for tens of thousands of miles on featureless seas, their ability to smell their way towards fish and home\"--Amazon.com.

Tensions in the China Seas: Background, Competition and Disputes
Over the past 10 to 15 years, the South China Sea (SCS) has emerged as an arena of U.S.-China strategic competition. China's actions in the SCS-including extensive island-building and base-construction activities at sites that it occupies in the Spratly Islands, as well as actions by its maritime forces to assert China's claims against competing claims by regional neighbors such as the Philippines and Vietnam-have heightened concerns among U.S. observers that China is gaining effective control of the SCS, an area of strategic, political, and economic importance to the United States and its allies and partners. Actions by China's maritime forces at the Japan-administered Senkaku Islands in the East China Sea (ECS) are another concern for U.S. observers. Chinese domination of China's near-seas region-meaning the SCS and ECS, along with the Yellow Sea-could substantially affect U.S. strategic, political, and economic interests in the Indo-Pacific region and elsewhere.
