In recent years there have been discovered, in the Central Arctic Ocean, some very curious ice-formations, known as ice-island. These islands are sharply distinct both from the old ice-fields of the Central Arctic regions and from the icebergs carved by the glaciers which descend into the Arctic Basin. The thickness of the Arctic ice fields (including the hummocks) usually does not exceed 3-5 meters, while the horizontal dimensions both in summer and particularly in winter may be very great (some tens of kilometers). Most of the East Greenland icebergs which have been surveyed had heights of about 70 m and lengths around 1 km. Thus the ratio of vertical to horizontal size is extremely small in ice fields, and in icebergs comparatively large. Ice islands occupy, in this respect, an intermediate position.

This book provides an overview of the current state of knowledge of Arctic ice shelves, ice islands and related features. Ice shelves are permanent areas of ice which float on the ocean surface while attached to the coast, and typically occur in very cold environments where perennial sea ice builds up to great thickness, and/or where glaciers flow off the land and are preserved on the ocean surface. These landscape features are relatively poorly studied in the Arctic, yet they are potentially highly sensitive indicators of climate change because they respond to changes in atmospheric, oceanic and glaciological conditions. Recent fracturing and breakup events of ice shelves in the Canadian High Arctic have attracted significant scientific and public attention, and produced large ice islands which may pose a risk to Arctic shipping and offshore infrastructure. Much has been published about Antarctic ice shelves, but to date there has not been a dedicated book about Arctic ice shelves or ice islands. This book fills that gap.

Download and read online ebook The Drift of Sea Ice write by Matti Leppäranta. This book was released on 2005. The Drift of Sea Ice available in PDF, EPUB and Kindle. The author presents in The Drift of Sea Ice 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. The science of sea ice drift through its 100-year history to the present day is explained. The text includes the geophysical theory, observations from field programs, and mathematical models. Topics covered include the science of sea ice drift, forecasting drift velocity based on volume, size and shape, sea ice ridging and remote sensing, modelling of the ice conditions, and finally the role of sea ice drift in research fields in ice-covered seas, oceanography, marine ecology and engineering.
