Book excerpt: The year is 1868, and fourteen-year-old Alika and his younger brother, Sulu, are hunting for seals on an ice floe attached to their island in the Arctic. Suddenly the ice starts to shake, and they hear a loud crack--the terrible sound of the floe breaking free from land. The boys watch with horror as the dark expanse of water between the ice and the shore rapidly widens, and they start drifting south--away from their home, their family, and everything they've ever known. Throughout their six-month-long journey down the Greenland Strait, the brothers face bitter cold, starvation, and most frightening of all, vicious polar bears. But they still remain hopeful that one day they'll be rescued. This thrilling new adventure story from bestselling author Theodore Taylor is a moving testament to the bond between brothers--and to the strength of the human spirit. Includes a map, a glossary of Inuit words and phrases, and an author's note..
Download or read book The Drift of Sea Ice written by Matti Leppäranta and published by Springer Science & Business Media. This book was released on 2011-03-22 with total page 370 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Second Edition of The Drift of Sea Ice presents the fundamental laws of sea ice drift which come from the material properties of sea ice and the basic laws of mechanics. The resulting system of equations is analysed for the general properties of sea ice drift, the free drift model and analytical models for ice drift in the presence of internal friction, and the construction of numerical ice drift models is detailed. This second edition of a much lauded work, unique on this topic in the English language, has been revised, updated and expanded with much new information and outlines recent results, in particular in relation to the climate problem, mathematical modelling and ice engineering applications. The current book presents the theory, observations, mathematical modelling techniques, and applications of sea ice drift science. The theory is presented from the beginning on a graduate student level, so that students and researchers coming from other fields such as physical oceanography, meteorology, physics, engineering, environmental sciences or geography can use the book as a source book or self-study material. First the drift ice material is presented ending with the concept of ‘ice state’ – the relevant properties in sea ice dynamics. Ice kinematics observations are widely presented with the mathematical analysis methods, and thereafter come drift ice rheology – to close the triangle material – kinematics – stress. The momentum equation of sea ice is derived in detail and its general properties are carefully analysed. Then follow two chapters on analytical models: free drift and drift in the presence of internal friction: These are very important tools in understanding the dynamical behaviour of sea ice. The last topical chapter is numerical models, which are the modern tool to solve ice dynamics problem in short term and long term problems. The closing chapter summarises sea ice dynamics applications and the need of sea ice dynamic knowledge and gives some final remarks on the future of this branch of science.
Download or read book Drift Deformation and Fracture of Sea Ice written by Jerome Weiss and published by Springer Science & Business Media. This book was released on 2013-03-14 with total page 95 pages. Available in PDF, EPUB and Kindle. Book excerpt: Sea ice is a major component of polar environments, especially in the Arctic where it covers the entire Arctic Ocean throughout most of the year. However, in the context of climate change, the Arctic sea ice cover has been declining significantly over the last decades, either in terms of its concentration or thickness. The sea ice cover evolution and climate change are strongly coupled through the albedo positive feedback, thus possibly explaining the Arctic amplification of climate warming. In addition to thermodynamics, sea ice kinematics (drift, deformation) appears as an essential factor in the evolution of the ice cover through a reduction of the average ice age (and consequently of the cover's thickness), or ice export out of the Arctic. This is a first motivation for a better understanding of the kinematical and mechanical processes of sea ice. A more upstream, theoretical motivation is a better understanding of the brittle deformation of geophysical objects across a wide range of scales. Indeed, owing to its very strong kinematics, compared e.g. to the Earth’s crust, an unrivaled kinematical data set is available for sea ice from in situ (e.g. drifting buoys) or satellite observations. Here, we review the recent advances in the understanding of sea ice drift, deformation and fracturing obtained from these data. We focus particularly on the scaling properties in time and scale that characterize these processes, and we emphasize the analogies that can be drawn from the deformation of the Earth’s crust. These scaling properties, which are the signature of long-range elastic interactions within the cover, constrain future developments in the modeling of sea ice mechanics. We also show that kinematical and rheological variables such as average velocity, average strain-rate or strength have significantly changed over the last decades, accompanying and actually accelerating the Arctic sea ice decline.
Download or read book Ice Drift Ocean Circulation and Climate Change written by Jens Bischof and published by Springer Science & Business Media. This book was released on 2000-11 with total page 254 pages. Available in PDF, EPUB and Kindle. Book excerpt: The issue of global warming and climate change is of continuous concern. Since the 1970s, it bas been shown that the pack-ice around the Arctic Ocean is thinning, the margin of permafrost is moving north and the vegetation in the high northern parts of the world is changing (the 'greening' of the Arctic). But are these changes the result of human activity or simply regular variations of the Earth's climate system? Over thousands of years, a continuous archive of iceberg and sea ice drift bas formed in the deep-sea sediments, revealing the place of the ice's origin and allowing a reconstruction of the surface currents and the climate of the past. However, the drift of floating ice from one place to another is not just a passive record of past ocean circulation. It actively influences and changes the surface ocean circulation, thus having a profound effect on climate change. Ice Drift, Ocean Circulation and Climate Change is the first book to focus on the interactions between ice, the ocean and the atmosphere and to describe how these three components of the climate system influence each other. It makes clear the positive contribution of paleoclimatology and paleoceanography and should be read by anyone concerned with global warming and climate change.

Download or read book Ice Ship written by Charles W. Johnson and published by ForeEdge from University Press of New England. This book was released on 2014-10-07 with total page 335 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the golden age of polar exploration (from the mid-1800s to the early 1900s), many an expedition set out to answer the big questionÑwas the Arctic a continent, an open ocean beyond a barrier of ice, or an ocean covered with ice? No one knew, for the ice had kept its secret well; ships trying to penetrate it all failed, often catastrophically. NorwayÕs charismatic scientist-explorer Fridtjof Nansen, convinced that it was a frozen ocean, intended to prove it in a novel if risky way: by building a ship capable of withstanding the ice, joining others on an expedition, then drifting wherever it took them, on a relentless one-way journey into discovery and fame . . . or oblivion. Ice Ship is the story of that extraordinary ship, the Fram, from conception to construction, through twenty years of three epic expeditions, to its final resting place as a museum. It is also the story of the extraordinary men who steered the Fram over the course of 84,000 miles: on a three-year, ice-bound drift, finding out what the Arctic really was; in a remarkable four-year exploration of unmapped lands in the vast Canadian Arctic; and on a twoÐyear voyage to Antarctica, where another famous Norwegian explorer, Roald Amundsen, claimed the South Pole. Ice Ship will appeal to all those fascinated with polar exploration, maritime adventure, and wooden ships, and will captivate readers of such books as The Endurance, In the Heart of the Sea, and The Last Place on Earth. With more than 100 original photographs, the book brings the Fram to life and light.

Book excerpt: National Outdoor Book Awards Winner Winner of the BANFF Adventure Travel Award “A thrilling and harrowing story. If it’s a cliche to say I couldn’t put this book down, well, too bad: I couldn’t put this book down.” —Jess Walter, bestselling author of Beautiful Ruins “Polar exploration is utter madness. It is the insistence of life where life shouldn’t exist. And so, Labyrinth of Ice shows you exactly what happens when the unstoppable meets the unmovable. Buddy Levy outdoes himself here. The details and story are magnificent.” —Brad Meltzer, bestselling author of The First Conspiracy: The Secret Plot to Kill George Washington Based on the author's exhaustive research, the incredible true story of the Greely Expedition, one of the most harrowing adventures in the annals of polar exploration. In July 1881, Lt. A.W. Greely and his crew of 24 scientists and explorers were bound for the last region unmarked on global maps. Their goal: Farthest North. What would follow was one of the most extraordinary and terrible voyages ever made. Greely and his men confronted every possible challenge—vicious wolves, sub-zero temperatures, and months of total darkness—as they set about exploring one of the most remote, unrelenting environments on the planet. In May 1882, they broke the 300-year-old record, and returned to camp to eagerly await the resupply ship scheduled to return at the end of the year. Only nothing came. 250 miles south, a wall of ice prevented any rescue from reaching them. Provisions thinned and a second winter descended. Back home, Greely’s wife worked tirelessly against government resistance to rally a rescue mission. Months passed, and Greely made a drastic choice: he and his men loaded the remaining provisions and tools onto their five small boats, and pushed off into the treacherous waters. After just two weeks, dangerous floes surrounded them. Now new dangers awaited: insanity, threats of mutiny, and cannibalism. As food dwindled and the men weakened, Greely's expedition clung desperately to life. Labyrinth of Ice tells the true story of the heroic lives and deaths of these voyagers hell-bent on fame and fortune—at any cost—and how their journey changed the world.

Download or read book A Memory of Ice written by Elizabeth Truswell and published by ANU Press. This book was released on 2019-08-01 with total page 247 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the southern summer of 1972/73, the Glomar Challenger was the first vessel of the international Deep Sea Drilling Project to venture into the seas surrounding Antarctica, confronting severe weather and ever-present icebergs. A Memory of Ice presents the science and the excitement of that voyage in a manner readable for non-scientists. Woven into the modern story is the history of early explorers, scientists and navigators who had gone before into the Southern Ocean. The departure of the Glomar Challenger from Fremantle took place 100 years after the HMS Challenger weighed anchor from Portsmouth, England, at the start of its four-year voyage, sampling and dredging the world’s oceans. Sailing south, the Glomar Challenger crossed the path of James Cook’s HMS Resolution, then on its circumnavigation of Antarctica in search of the Great South Land. Encounters with Lieutenant Charles Wilkes of the US Exploring Expedition and Douglas Mawson of the Australasian Antarctic Expedition followed. In the Ross Sea, the voyages of the HMS Erebus and HMS Terror under James Clark Ross, with the young Joseph Hooker as botanist, were ever present. The story of the Glomar Challenger’s iconic voyage is largely told through the diaries of the author, then a young scientist experiencing science at sea for the first time. It weaves together the physical history of Antarctica with how we have come to our current knowledge of the polar continent. This is an attractive, lavishly illustrated and curiosity-satisfying read for the general public as well as for scholars of science.

Book excerpt: A haunting tale of psychological suspense from Iceland's premier novelist, Steinar Bragi. "This is Iceland's Twin Peaks ... A thriller and a relationship drama so skillfully told that it is difficult to put the book down" Corren (Sweden) Set against Iceland's volcanic hinterlands, four thirty-somethings from Reykjavik - the reckless hedonist Egill; the recovering alcoholic Hrafin; and their partners Anna and Vigdis - embark on an ambitious camping trip, their jeep packed with supplies. Victims of the financial crisis, the purpose of the trip is to heal both professional and personal wounds, but the desolate landscape forces the group to reflect on the shattered lives they've left behind in the city. As their jeep hurtles through the barren land, an impenetrable fog descends, causing them to suddenly crash into a rural farmhouse. Seeking refuge from the storm, the group discover that the isolated dwelling is inhabited by a mysterious elderly couple who inexplicably barricade themselves inside every night. As past tensions within the group rise to the surface, the merciless weather blocks every attempt at escape, forcing them to ask difficult questions: who has been butchering animals near the house? What happened to the abandoned village nearby where bones lie strewn across the ground? And most importantly, will they ever return home?
Download or read book Air Ice Ocean Interaction written by Miles McPhee and published by Springer Science & Business Media. This book was released on 2008-06-04 with total page 218 pages. Available in PDF, EPUB and Kindle. Book excerpt: At a time when the polar regions are undergoing rapid and unprecedented change, understanding exchanges of momentum, heat and salt at the ice-ocean interface is critical for realistically predicting the future state of sea ice. By offering a measurement platform largely unaffected by surface waves, drifting sea ice provides a unique laboratory for studying aspects of geophysical boundary layer flows that are extremely difficult to measure elsewhere. This book draws on both extensive observations and theoretical principles to develop a concise description of the impact of stress, rotation, and buoyancy on the turbulence scales that control exchanges between the atmosphere and underlying ocean when sea ice is present. Several interesting and unique observational data sets are used to illustrate different aspects of ice-ocean interaction ranging from the impact of salt on melting in the Greenland Sea marginal ice zone, to how nonlinearities in the equation of state for seawater affect mixing in the Weddell Sea. The book’s content, developed from a series of lectures, may be appropriate additional material for upper-level undergraduates and first-year graduate students studying the geophysics of sea ice and planetary boundary layers.

Download or read book On Sea Ice written by Willy Weeks and published by University of Alaska Press. This book was released on 2010-06-15 with total page 682 pages. Available in PDF, EPUB and Kindle. Book excerpt: Covering more than seven percent of the earth’s surface, sea ice is crucial to the functioning of the biosphere—and is a key component in our attempts to understand and combat climate change. With On Sea Ice, geophysicist W. F. Weeks delivers a natural history of sea ice, a fully comprehensive and up-to-date account of our knowledge of its creation, change, and function. The volume begins with the earliest recorded observations of sea ice, from 350 BC, but the majority of its information is drawn from the period after 1950, when detailed study of sea ice became widespread. Weeks delves into both micro-level characteristics—internal structure, component properties, and phase relations—and the macro-level nature of sea ice, such as salinity, growth, and decay. He also explains the mechanics of ice pack drift and the recently observed changes in ice extent and thickness. An unparalleled account of a natural phenomenon that will be of increasing importance as the earth’s temperature rises, On Sea Ice will unquestionably be the standard for years to come.
