Available in PDF, EPUB and Kindle. Book excerpt: The book is based on results from the Russian expedition in the region of the Antarctic Peninsula and Powell Basin in the northern part of the Weddell Sea, as well as on the review of earlier research in the region. The main goal of the research was to collect the newest data and study the physical properties and ecology of this key region of the Southern Ocean. Data analysis is supplemented with numerical modeling of the atmosphere-ocean interaction and circulation in the adjacent region, including research on rogue waves. The focus of the study was the Antarctic Circumpolar Current, currents and water properties in the Bransfield Strait and Antarctic Sound, properties of seawater, currents, ecosystem and biological communities in the Powell Basin of the northwestern Weddell Sea, and their variations. An attempt is made to reveal the role of various components of the Antarctic environment in the formation of biological productivity and maintenance of the Antarctic krill population. This is especially important as in the last decades the Antarctic environment has experienced significant changes related to the global climatic trends.

This book was released on 2006 with total page 136 pages. Available in PDF, EPUB and Kindle. Book excerpt: Recent high-resolution underway observations in Drake Passage are employed to study the surface-layer currents and momentum balance of the Antarctic Circumpolar Current (ACC). Ocean currents were measured with a ship-mounted acoustic Doppler current profiler and upper ocean temperatures surveyed with expendable bathythermographs deployed from the R/V Laurence M Gould, during every season of the annual cycle over a 5-year period. The finely-resolved mean flow estimated from observed currents shows the topographic control of the mean Subantarctic Front (SAF) and the along-stream convergence of multiple filaments of the Polar Front (PF) and Southern ACC Front (SACCF) into single mean jets. Mean cross-track transport above 250 m is 28.7 " 1 Sv and accounts for 20% of the total Drake Passage transport. Subtracting geostrophic current anomalies inferred from altimetry from the instantaneous velocity observations markedly reduces the velocity variance and results in an improved estimate of mean currents. Variance is attributed to mesoscale eddies, inertial currents, and least of all, baroclinic tides. Horizontal-wavenumber spectra of velocity fluctuations peak at wavelengths of?200 km and are significantly anisotropic in a manner consistent with aspects of geostrophic turbulence. Eddy kinetic energy is surface intensified and decreases poleward in Drake Passage; in situ estimates are significantly higher than altimetric estimates everywhere. A mean Ekman spiral observed in Drake Passage verifies the Ekman balance; the Ekman layer is approximately 100 m deep. Eddy momentum and heat fluxes are averaged along streamlines inferred from the improved mean flow. These indicate that eddies flux vorticity along the axis of the SAF in the vicinity of the Patagonian continental slope and accelerate the PF in Drake Passage. However, the eddy forcing is small, implying that eddies transmit the surface wind stress downwards undiminished via an interfacial form stress. Variability in specific dynamic height contours correlated with each ACC front is used to examine the meandering and topographic control of the Drake Passage fronts. Finally an analysis of the annual cycle of the circulation of Port Foster, Deception Island is presented. Moored observations of water temperature, currents and acoustic backscatter show that seasonal, tidal and diurnal processes dominate the variability of this ecosystem.

Book excerpt: “The Southern Ocean is a wild and elusive place, an ocean like no other. With its waters lying between the Antarctic continent and the southern coastlines of Australia, New Zealand, South America, and South Africa, it is the most remote and inaccessible part of the planetary ocean, the only part that flows around Earth unimpeded by any landmass. It is notorious amongst sailors for its tempestuous winds and hazardous fog and ice. Yet it is a difficult ocean to pin down. Its southern boundary, defined by the icy continent of Antarctica, is constantly moving in a seasonal dance of freeze and thaw. To the north, its waters meet and mingle with those of the Atlantic, Indian, and Pacific Oceans along a fluid boundary that defies the neat lines of a cartographer.” So begins Joy McCann’s Wild Sea, the remarkable story of the world’s remote Southern, or Antarctic, Ocean. Unlike the Pacific, Atlantic, Indian, and Arctic Oceans with their long maritime histories, little is known about the Southern Ocean. This book takes readers beyond the familiar heroic narratives of polar exploration to explore the nature of this stormy circumpolar ocean and its place in Western and Indigenous histories. Drawing from a vast archive of charts and maps, sea captains’ journals, whalers’ log books, missionaries’ correspondence, voyagers’ letters, scientific reports, stories, myths, and her own experiences, McCann embarks on a voyage of discovery across its surfaces and into its depths, revealing its distinctive physical and biological processes as well as the people, species, events, and ideas that have shaped our perceptions of it. The result is both a global story of changing scientific knowledge about oceans and their vulnerability to human actions and a local one, showing how the Southern Ocean has defined and sustained southern environments and people over time. Beautifully and powerfully written, Wild Sea will raise a broader awareness and appreciation of the natural and cultural history of this little-known ocean and its emerging importance as a barometer of planetary climate change.
