Charting Northern Waters also offers a detailed review of Russian hydrography on their northern coast from 1900 to 1940 and an in-depth discussion of American oceanographic work in the north in 1951. Other topics include the Labrador survey of HMS Challenger in 1932-34, German hydrographic and oceanographic support of the U-boat campaign in Canadian waters during World War II, and Canadian technical developments over the past fifty years.

Do you only have a week to spare? For those of us who are time poor but who want to seize the moment, either on our own boat or on a charter, it’s reassuring to know that there are plenty of cruising hubs from where we can enjoy some of the best of the region in only a few days. Imray Pocket Pilots are a new series of affordable PDF books, companions to the Yachting Monthly series A Week Afloat. They visit some ideal destinations and suggest a one week itinerary, and include expanded sailing directions for cruising each area based on printed Imray pilot books. Familiar Imray chartlets cover marina detail and approaches, and photos add both information and colour to the downloads. This Imray Pocket Pilot covers The Ionian, Greece.

As in previous editions, the symbols used on paper nautical charts produced by NOAA and the NGA and digital raster representations of those charts, such as NOAA Raster Nautical Chart (NOAA RNC's), are presented in lettered sections organized in categories, such as Landmarks, Depths, and Lights.

Initial results of a continuing study to analyze and summarize the acoustically significant characteristics of the vertical sound-speed structure in the Indian Ocean are presented for purposes of acoustic model inputs and future exercise planning in the region. Data displays cover the western Indian Ocean west of 75 degrees E and north of 20 degrees S. Hydrocast data with computed sound speeds at standard depths provide the basic information to define areas of the Indian Ocean that are reasonably homogeneous with regard to sound-speed properties and can be summarized by a single profile for each season. Seasonal data presentations of bottom conjugate depth (the shallow conjugate of the bottom sound speed) and depth excess (water depth below the deep conjugate of the near-surface sound-speed maximum) indicate the primarily bottom-limited situation in the western Indian Ocean and identify the restricted areas of the Somali Basin with convergence-zone propagation potential. The upper-layer characteristics of layer depth, in-layer gradient, and below-layer gradient are displayed seasonally in contour format based on sound-speed-converted BT and XBT temperature data. Emphasis is placed on the significant effects of the seasonal monsoons, and in particular the strong SW Monsoon, on the near-surface structure. Results based on the two data sources are presented separately and some comparisons are made.

For more than thirty years, the History of Cartography Project has charted the course for scholarship on cartography, bringing together research from a variety of disciplines on the creation, dissemination, and use of maps. Volume 6, Cartography in the Twentieth Century, continues this tradition with a groundbreaking survey of the century just ended and a new full-color, encyclopedic format. The twentieth century is a pivotal period in map history. The transition from paper to digital formats led to previously unimaginable dynamic and interactive maps. Geographic information systems radically altered cartographic institutions and reduced the skill required to create maps. Satellite positioning and mobile communications revolutionized wayfinding. Mapping evolved as an important tool for coping with complexity, organizing knowledge, and influencing public opinion in all parts of the globe and at all levels of society. Volume 6 covers these changes comprehensively, while thoroughly demonstrating the far-reaching effects of maps on science, technology, and society—and vice versa. The lavishly produced volume includes more than five hundred articles accompanied by more than a thousand images. Hundreds of expert contributors provide both original research, often based on their own participation in the developments they describe, and interpretations of larger trends in cartography. Designed for use by both scholars and the general public, this definitive volume is a reference work of first resort for all who study and love maps.

An examination of the lingering effects of a hydroelectric power station on Pimicikamak sovereign territory in Manitoba, Canada. The child of South Asian migrants, Kazim Ali was born in London, lived as a child in the cities and small towns of Manitoba, and made a life in the United States. As a man passing through disparate homes, he has never felt he belonged to a place. And yet, one day, the celebrated poet and essayist finds himself thinking of the boreal forests and lush waterways of Jenpeg, a community thrown up around the building of a hydroelectric dam on the Nelson River, where he once lived for several years as a child. Does the town still exist, he wonders? Is the dam still operational? When Ali goes searching, however, he finds not news of Jenpeg, but of the local Pimicikamak community. Facing environmental destruction and broken promises from the Canadian government, they have evicted Manitoba’s electric utility from the dam on Cross Lake. In a place where water is an integral part of social and cultural life, the community demands accountability for the harm that the utility has caused. Troubled, Ali returns north, looking to understand his place in this story and eager to listen. Over the course of a week, he participates in community life, speaks with Elders and community members, and learns about the politics of the dam from Chief Cathy Merrick. He drinks tea with activists, eats corned beef hash with the Chief, and learns about the history of the dam, built on land that was never ceded, and Jenpeg, a town that now exists mostly in his memory. In building relationships with his former neighbors, Ali explores questions of land and power?and in remembering a lost connection to this place, finally finds a home he might belong to.

A graceful, elegant account even when reporting on the hard truths of a little-known corner of the world.” —Kirkus Reviews “[Ali’s] experiences are relayed in sensitive, crystalline prose, documenting how Cross Lake residents are working to reinvent their town and rebuild their traditional beliefs, language, and relationships with the natural world. . . . Though these topics are complex, they are untangled in an elegant manner.” —Foreword Reviews (starred review)
