Secrets of the Viking Navigators: How the Vikings Used Their Amazing Sunstones and Other Techniques to Cross the Open Ocean by Leif K. Karlsen Pdf
Most navigators have heard of Viking sunstones, but few realize they are more than legend. Leif Karlsen has brought them to life. He shows us how they work--now, and a thousand years ago--and what it was that led the Viking navigators to develop this unique tool for finding the direction to the sun, even when the sun is obscured by clouds or fog.
Secrets of the Viking Navigators by Leif K. Karlsen Pdf
"Most navigators have heard of Viking sunstones, but few realize they are more than legend. Leif Karlsen has brought them to life. He shows us how they work-now, and a thousand years ago-and what it was that led the Viking navigators to develop this unique tool for finding the direction to the sun, even when the sun is obscured by clouds or fog." -David Burch, PhD, FIN, Director, Starpath School of Navigation "Using clues he gleaned from the Icelandic Sagas, his experience as a professional navigator, and from his voyages on "Borgunknarren"-a 60' Viking ship replica-Leif K. Karlsen reveals the secrets of Viking navigation. Karlsen has done extensive research on the Viking "sunstone" and "horizon board" and explains how they work. This is an interesting, valuable, and educational contribution to the understanding of the Vikings' success as navigators and seamen." -Dr. Alf Lunder Knudsen, Editor Emeritus Western Viking "The Norwegian Voice of America -Since 1889 If "cutting edge" can be used in relation to Viking navigation, this information is definitely it. Leif Karlsen is the world's foremost scholar on the Viking sunstone. His well-researched and intelligent work on Viking navigation examines the sagas and combines that information with the experiential and practical research of just trying it out. It's a comprehensive and accessible study that's also a compelling analysis of the secrets of Viking navigators, and their unparalled success as sea-born explorers." -Kristine Leander, Ph.D., Director, Leif Erikson International Foundation
How was the Norse Navigator able to shape his course across the North Atlantic long before the invention of the magnetic compass? This book tells the story of the Viking Sun Compass and how it allowed the Vikings to sail across the Atlantic. In 1948, the Danish archaeologist C.L. Veb�k found the remains of a small wooden disc at the Viking Age site of Uunartoq in Greenland. Since then the Master mariners Carl V. Sver and Sen Thirslund have interpreted this find as a navigational instrument. This book is the essence of more than forty years of archaeological studies, discussions and practical sea-going experiments. The author gives a full account of the history of the find and demonstrates convincingly how Viking Age Navigators could make use of this and other simple devices in order to find their way across the vastness of the Northern Atlantic.
'Barefoot navigation: 5,000 years in the making.' Barefoot Navigator introducesus to a unique take on navigation – using the skills of the ancients and technology-free techniques, we learn how to navigate using the sun, sea, wind and stars, and even the flight patterns of ocean birds. The first part of this absorbing book recounts a colourful history of seafarers and their navigation techniques. How did the Polynesians manage to populate an area of ocean larger than North America simply by analysing clouds,currents and wind direction? How did the Vikings routinely travel on the notorious stretches of water between Iceland, Greenland and Scandinavia? The second part shows how to use these ancient techniques to supplement today's navigational hardware, especially in survival situations. Fascinating history, useful advice, enjoyable writing, and different to every other navigation reference out there, this second edition has been beautifully packaged in a hardback format, with new illustrations and thoroughly revised text.

Adventurer and navigation expert Tristan Gooley unlocks the directional clues hidden in the sun, moon, stars, clouds, weather patterns, lengthening shadows, changing tides, plant growth, and the habits of wildlife. Rich with navigational anecdotes collected across ages, continents, and cultures, The Natural Navigator will help keep you on course and open your eyes to the wonders, large and small, of the natural world.
The Lost Art of Finding Our Way by John Edward Huth Pdf
Long before GPS, Google Earth, and global transit, humans traveled vast distances using only environmental clues and simple instruments. John Huth asks what is lost when modern technology substitutes for our innate capacity to find our way. Encyclopedic in breadth, weaving together astronomy, meteorology, oceanography, and ethnography, The Lost Art of Finding Our Way puts us in the shoes, ships, and sleds of early navigators for whom paying close attention to the environment around them was, quite literally, a matter of life and death. Haunted by the fate of two young kayakers lost in a fog bank off Nantucket, Huth shows us how to navigate using natural phenomena—the way the Vikings used the sunstone to detect polarization of sunlight, and Arab traders learned to sail into the wind, and Pacific Islanders used underwater lightning and “read” waves to guide their explorations. Huth reminds us that we are all navigators capable of learning techniques ranging from the simplest to the most sophisticated skills of direction-finding. Even today, careful observation of the sun and moon, tides and ocean currents, weather and atmospheric effects can be all we need to find our way. Lavishly illustrated with nearly 200 specially prepared drawings, Huth’s compelling account of the cultures of navigation will engross readers in a narrative that is part scientific treatise, part personal travelogue, and part vivid re-creation of navigational history. Seeing through the eyes of past voyagers, we bring our own world into sharper view.
