An interdisciplinary study of the Kuroshio nutrient stream The surface water of the Kuroshio, a western boundary current in the North Pacific Ocean, is nutrient-depleted and has relatively low primary productivity, yet abundant fish populations are supported in the region. This is called the “Kuroshio Paradox”. Kuroshio Current: Physical, Biogeochemical and Ecosystem Dynamics presents research from a multidisciplinary team that conducted observational and modeling studies to investigate this contradiction. This timely and important contribution to the ocean sciences literature provides a comprehensive analysis of the Kuroshio. Volume highlights include: New insights into the role of the Kuroshio as a nutrient stream The first interdisciplinary examination of the Kuroshio Paradox Reflections on the influence of the Kuroshio on Japanese culture Research results on both the lower and higher trophic levels in the Kuroshio ecosystem Comparisons of nutrient dynamics in the Kuroshio and Gulf Stream Predictions of ecosystem responses to future climate variability

Measuring Ocean Currents: Tools, Technologies, and Data covers all major aspects of ocean current measurements in view of the implications of ocean currents on changing climate, increasing pollution levels, and offshore engineering activities. Although more than 70% of the Earth is covered by ocean, there is limited information on the countless fine- to large-scale water motions taking place within them. This book fills that information gap as the first work that summarizes the state-of-the-art methods and instruments used for surface, subsurface, and abyssal ocean current measurements. Readers of this book will find a wealth of information on Lagrangian measurements, horizontal mapping, imaging, Eulerian measurements, and vertical profiling techniques. In addition, the book describes modern technologies for remote measurement of ocean currents and their signatures, including HF Doppler radar systems, satellite-borne sensors, ocean acoustic tomography, and more. Crucial aspects of ocean currents are described in detail as well, including dispersion of effluents discharged into the sea and transport of beneficial materials—as well as environmentally hazardous materials—from one region to another. The book highlights several important practical applications, showing how measurements relate to climate change and pollution levels, how they affect coastal and offshore engineering activities, and how they can aid in tsunami detection. Coverage of measurement, mapping and profiling techniques Descriptions of technologies for remote measurement of ocean currents and their signatures Reviews crucial aspects of ocean currents, including special emphasis on the planet-spanning thermohaline circulation, known as the ocean's "conveyor belt," and its crucial role in climate change

Pioneering oceanographer Curtis Ebbesmeyer unravels the mystery of marine currents, uncovers the astonishing story of flotsam, and changes the world's view of trash, the ocean, and our global environment. Curtis Ebbesmeyer is no ordinary scientist. He's been a consulting oceanographer for multinational firms and a lead scientist on international research expeditions, but he's never held a conventional academic appointment. He seized the world's imagination as no other scientist could when he and his worldwide network of beachcomber volunteers traced the ocean's currents using thousands of sneakers and plastic bath toys spilled from storm-tossed freighters. Now, for the first time, Ebbesmeyer tells the story of his lifelong struggle to solve the sea's mysteries while sharing his most surprising discoveries. He recounts how flotsam has changed the course of history—leading Viking mariners to safe harbors, Columbus to the New World, and Japan to open up to the West—and how it may even have made the origin of life possible. He chases icebergs and floating islands; investigates ocean mysteries from ghost ships to a spate of washed-up severed feet on Canadian beaches; and explores the enormous floating "garbage patches" and waste-heaped "junk beaches" that collect the flotsam and jetsam of industrial society. Finally, Ebbesmeyer reveals the rhythmic and harmonic order in the vast oceanic currents called gyres—"the heartbeat of the world "—and the threats that global warming and disintegrating plastic waste pose to the seas . . . and to us.

Elements of Physical Oceanography is a derivative of the Encyclopedia of Ocean Sciences, Second Edition and serves as an important reference on current physical oceanography knowledge and expertise in one convenient and accessible source. Its selection of articles—all written by experts in their field—focuses on ocean physics, air-sea transfers, waves, mixing, ice, and the processes of transfer of properties such as heat, salinity, momentum and dissolved gases, within and into the ocean. Elements of Physical Oceanography serves as an ideal reference for topical research. References related articles in physical oceanography to facilitate further research Richly illustrated with figures and tables that aid in understanding key concepts Includes an introductory overview and then explores each topic in detail, making it useful to experts and graduate-level researchers Topical arrangement makes it the perfect desk reference

From a study of knowledge of the sea among indigenous cultures in the South Seas to inquiries into the subject of sea monsters, from studies of Pacific currents to descriptions of ocean-going research vessels, the sixty-three essays presented here reflect the scientific complexity and richness of social relationships that characterize ocean-ographic history. Based on papers presented at the Fifth International Congress on the History of Oceanography held at the Scripps Institution of Oceanography (the first ICHO meeting following the cessation of the Cold War), the volume features an unusual breadth of contributions. Oceanography itself involves the full spectrum of physical, biological, and earth sciences in their formal, empirical, and applied manifestations. The contributors to Oceanographic History: The Pacific and Beyond undertake the interdisciplinary task of telling the story of oceanography’s past, drawing on diverse methodologies. Their essays explore the concepts, techniques, and technologies of oceanography, as well as the social, economic, and institutional determinants of oceanographic history. Although focused on the Pacific, the geographic range of subjects is global and includes Micronesia, East Africa, and Antarctica; the bathymetric range comprises inshore fisheries, coral reefs, and the "azoic zone." The seventy-one contributors represent every continent of the globe except Antarctica, bringing together material on the history of oceanography never before published.
