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.
