The project began in 1993 as a effort to design and construct an Arctic capable low frequency acoustic source at 20 Hertz with acoustic power of 195-200 dB. The objective of the effort was to test the feasibility of acoustic monitoring of the Arctic Ocean and ice cap using long range low frequency acoustic propagation, by answering the fundamental questions: (1) What source level would be required to reliably propagate at 20 Hertz across the Arctic Basin?, (2) Will the Arctic acoustic channel be stable enough to permit precise phase and/or travel time measurements?, and (3) Will modes/rays be stable, identifiable and predictable? The design study of Arctic capable acoustic sources was completed in December 1993 and a decision was made to go forward with the manufacture of an acoustic source by the Institute of Applied Physics, Nizhny Novgorod, Russia. The results of the design study by the Institute of Applied Physics are included in this report. It was also decided to support a experiment in the Arctic in April 1994 to be known as the Transarctic Acoustic Propagation (TAP) Experiment. The objectives of the experiment would be to test the acoustic source and the hypotheses of acoustic monitoring of the Arctic Ocean.

The North Pacific Research Board (NPRB) was established in 1997 as custodian to a pool of funds intended for the study of the North Pacific Ocean, Bering Sea, and Arctic Ocean. The success of the NRPB is the development of a high quality, long-range science plan that provides a better understanding of ecosystems and their fisheries in the region. This report provides a framework to help the NPRB identify appropriate science themes and mechanisms for administering and distributing the funds. It contains extensive input from residents of Alaskan communities, to help scientists understand and address issues of importance to the local communities. The book makes specific recommendations on long-term research priorities, the NPRB management structure and the development of future programs.

Covering 71 percent of the planet, these saline bodies of water provided the unique conditions necessary for the building blocks of life to form billions of years ago. This book explains how our oceans continue to support and influence life in important ways: by providing the largest global source of protein in the form of fish populations, by creating and influencing weather systems, and by absorbing waste streams such as airborne carbon. It is shown how oceans have an almost magnetic draw—almost half of the world’s population lives within a few hours of an ocean. Although oceans are vast in size, exceeding 328 million cubic miles (1.37 billion cubic kilometers), they have been influenced by and have influenced humans in numerous ways. The book includes three detailed case studies. The first focuses on the most remote locations along the Mid-Atlantic Ridge, where new ocean floor is being formed twenty-thousand feet underwater. The second considers the Maldives, a string of islands in the Indian Ocean, where increasing sea levels may force residents to abandon some communities by 2020. The third describes the North Sea at the edge of the Arctic Ocean, where fishing stocks have been dangerously depleted as a result of multiple nations’ unrelenting removal of the smallest and largest species.

The Pacific Arctic region is experiencing rapid sea ice retreat, seawater warming, ocean acidification and biological response. Physical and biogeochemical modeling indicates the potential for step-function changes to the overall marine ecosystem. This synthesis book was coordinated within the Pacific Arctic Group, a network of international partners working in the Pacific Arctic. Chapter topics range from atmospheric and physical sciences to chemical processing and biological response to changing environmental conditions. Physical and biogeochemical modeling results highlight the need for data collection and interdisciplinary modeling activities to track and forecast the changing ecosystem of the Pacific Arctic with climate change.

The Arctic region is the keystone to understanding the present status ofcurrently ongoing Earth systems and to predicting future imagesof our planet as viewed from northern high latitudes. The Arctic region,composed of ice-covered Arctic ocean in its center and surroundingfragmentation of the major continents, has been investigatedduring the last half century through all kinds of scientific studies:bioscience, physical sciences, geoscience, oceanography, and environmental studies, together with the technological domain. This book covers topics on the recent developments of all kinds of scientific research in and around the Arctic region, with a view to monitoring the current variations in the extreme environment, affected by remarkable changes in temperature and sea-ice extent, mass loss of ice-sheet and glaciers, and variations in marine and terrestrial ecosystems, including human activities.

The Ecosystems series is the only source that offers a complete understanding of global ecology. Illustrated with beautiful full-colour photographs, each volume combines the "hard sciences," such as biology and chemistry, with history, economics, and environmental studies. Each ecosystem is presented in its entirety with details on its history, biology, wildlife, beauty, problems, and influence on culture. This interdisciplinary approach emphasizes the complex, interrelated nature of each biome - giving readers the most integrated portrayal of the natural world available. Each volume spans Europe, Asia, Australia, Antarctica, and the Americas to present a particular ecosystem. Coverage offers a basic introduction to ecological concepts and demonstrates how these concepts influence the complex relationship between humans and the environment.

The Arctic Ocean is the smallest of the five oceans. Its surface is almost entirely covered in ice. While this frigid body of water may seem inhospitable to life, in reality, millions of unique plants and animals thrive below the ice. The Our Five Oceans series features stunning visuals, detailed maps, educational debates, and challenging research activities. Each book explores key topics such as ocean life, ecosystems, and environmental issues, in order to help readers better understand the importance of protecting the world’s oceans.

The oceans are our planet's most distinctive and imposing natural habitat. They cover 71 percent of its surface; support a remarkably diverse and exquisitely adapted array of life forms, from microscopic viruses, bacteria, and plankton to the largest existing animals; and possess many of Earth's most significant, intriguing, and inaccessible ecosystems. In an era in which humans are significantly altering the global environment, the oceans are undergoing rapid and profound changes. The study of marine biology is thus taking on added importance and urgency as people struggle to understand and manage these changes to protect our marine ecosystems. Healthy oceans produce half of the oxygen we breathe; stabilize our climate; create ecosystems that protect our coasts from storms; provide us with abundant food; and host diverse organisms that provide us with natural products for medicine and biotechnology. In this Very Short Introduction, marine biologist Philip Mladenov provides an accessible and up-to-date overview of marine biology, offering a tour of marine life and marine processes that ranges from the unimaginably abundant microscopic organisms that drive the oceans' food web to the apex predators that we exploit for food; from polar ocean ecosystems to tropical coral reefs; and from the luxurious kelp beds of the coastal ocean to deep-ocean hydrothermal vents where life exists without the energy of the sun. Throughout the book he considers the human impacts on marine life including overfishing, plastic and nutrient pollution, the spread of exotic species, and ocean warming and acidification. He discusses the threats these pose to our welfare, and the actions required to put us on a path to a more sustainable relationship with our oceans so that they can be restored and protected for future generations. Mladenov concludes with a new chapter offering an inspiring vision for the future of our oceans in 2050 that can be realised if we are wise enough to accelerate actions already underway and be bold with implementing new approaches. The next decade will decide the state of the oceans that we leave behind for future generations. ABOUT THE SERIES: The Very Short Introductions series from Oxford University Press contains hundreds of titles in almost every subject area. These pocket-sized books are the perfect way to get ahead in a new subject quickly. Our expert authors combine facts, analysis, perspective, new ideas, and enthusiasm to make interesting and challenging topics highly readable.
