This book was released on 1962 with total page 126 pages. Available in PDF, EPUB and Kindle. Book excerpt: Oceanographic obs rvation in the sou h rn Beaufort Sea of the Arctic Ocean were conducted at Fletcher's Ice Island (T-3) between June 1959 and September 1960. An lysis of data on temperature, salinity, and chemical elements revealed five major water masses in his region: Arctic Surface Water, Upper Intermediate Water, Atlantic Water, Low Intermediate Water, and Deep Shelf Water. Intrusion of relatively warm Pacific Water along the 25.5 - 26.0 isopycnal surface at about 75 m was characteristic. The temperature structure of the deep water in the Beaufort Basin showed that there is a relatively warm water mass at depths below 880 m (Lo r Intermediate Water), which is warmer than bottom waters in the Atlantic Water occurring between he upper and lower 0 C isotherms (250 m and 880 m respectively) is characterized by positive temperatures, having a maximum of 0.45 C at about 450 m. Deep Shelf Water is found at 15 m to 40 m on the very shallow continental shelf, being characterized by relatively low temperatures and abundance of silicon. E SONAL CHANGES IN TEMPERATURE AND OTHER OCEANOGRAPHIC ELEMENTS IN THE SURFACE LAYER ARE DESCRIBED IN CONNECTION WITH SUMMER HEATING AND WINTER ICE FORMATION. (Au hor).

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 Arctic Ice Shelves and Ice Islands written by Luke Copland and published by Springer. This book was released on 2017-05-30 with total page 426 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
