Book Description
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.

Book Description
SEA ICE The latest edition of the gold standard in sea ice references In the newly revised second edition of Sea Ice: Physics and Remote Sensing, a team of distinguished researchers delivers an in-depth review of the features and structural properties of ice, as well as the latest advances in geophysical sensors, ice parameter retrieval techniques, and remote sensing data. The book has been updated to reflect the latest scientific developments in macro- and micro-scale sea ice research. For this edition, the authors have included high-quality photographs of thin sections from cores of various ice types, as well as a comprehensive account of all major field expeditions that have systematically surveyed sea ice and its properties. Readers will also find: A thorough introduction to ice physics and physical processes, including ice morphology and age-based structural features Practical discussions of radiometric and radar-scattering observations from sea ice, including radar backscatter and microwave emission The latest techniques for the retrieval of sea ice parameters from space-borne and airborne sensor data New chapters on sea ice thermal microwave emissions and on the impact of climate change on polar sea ice Perfect for academic researchers working on sea ice, the cryosphere, and climatology, Sea Ice: Physics and Remote Sensing will also benefit meteorologists, marine operators, and high-latitude construction engineers.

Physical Measurements of Sea Ice
Author: J. H. BrownPublisher:
ISBN:
Category : Ice
Languages : en
Pages : 26
Book Description
During the Winter 1954 Bering Sea Expedition and the Winter 1955 Bering Sea Expedition, measurements were made of the longitudinal plate-wave velocity. In 1954, the location of the ice sheet in which measurements were made was 60 deg 20 min N, 168 deg 38 min W; and in 1955 the ice sheet, although variable in position during the several days measurements were being made, occupied the position 63 deg 05 min N, 166 deg 09 min W. In 1955, in addition to the measurement of the longitudinal plate-wave velocity, other physical properties of the ice which might be of scientific interest were measured. The investigation of other sea-ice parameters included: (1) sampling profiles of density, temperature, salinity, air bubble, and crystal grain; (2) measurement of the longitudinal wave velocity in ice rods; (3) measurement of the frequency of air-coupled flexural waves to determine ice thickness; and (4) resistivity measurements.
Field Techniques for Sea-Ice Research

Book Description
As much as one-tenth of the world’s oceans are covered with sea ice, or frozen ocean water, at some point during the annual cycle. Sea ice thus plays an important, often defining, role in the natural environment and the global climate system. This book is a global look at the changes in sea ice and the tools and techniques used to measure and record those changes. The first comprehensive research done on sea-ice field techniques, this volume will be indispensable for the study of northern sea ice and a must-have for scientists in the field of climate change research.
Surface Temperatures and Growth of Sea Ice

Book Description
Sea-ice surface temperatures observed at Eureka, N.W.T., Canada, during 1949-50 and 1950-51 were used to compute the numerical value of the expression k/L rho, where k = thermal conductivity, L = latent heat of fusion and rho = density. The numerical value for these combined physical properties of sea ice was found to increase from approximately 0.000047 to 0.00007 during ice growth (between 6 November and 22 December) from 0.6 to 1 m thickness. During the increase from 1.1 to 1.3 m (between 20 January and 10 February) the value of k/L rho ranged from 0.00007 to 0.00008 and then decreased slightly during the rest of the growth period. These variations in the value of k/L rho throughout the winter season were considered as changes in the effective conductivity caused by physical changes and distribution of brine in the sea ice. Since no observations on sea-ice salinity were made at Eureka, it was not possible to investigate the effect of the physical properties separately. A study on the relation between sea-ice accretion and temperature gradient disclosed a correlation coefficient of r = 0.73. (Author).
