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.

Arctic sea ice has been declining rapidly since 1979. Larger areas of open ocean allow more energy absorption and surface-atmosphere energy and moisture exchanges especially during summer. Therefore, sea ice in turn modulates local climate and potentially the global climate system. Many studies have investigated influences of Arctic atmospheric circulations on sea ice. Yet few have studied the climatic effects of declining Arctic sea ice cover during the warm season. This study explores the relationship between summer Arctic sea-ice area and subsequent winter North Atlantic Oscillation and the mechanisms that may link them across the annual cycle. Statistically significant positive correlations are found between summer sea-ice area and subsequent winter NAO. Approximately 30% of the winter NAO variance can be explained by summer sea-ice area. In addition, strong correlations between Arctic summer sea-ice area and subsequent winter sea-level pressure, 500-hPa geopotential height, surface air and SST fields are found. All these relationships, except SSTs, depict the dipole structure characterized by the NAO, the simultaneous strengthening and weakening of the Azores high and the Icelandic low. From these results, neutral or negative NAO phase is to be expected in winters after low sea-ice summers; positive NAO phase is expected in winters after summers with larger than average sea-ice area. Physical processes that lead to this relationship are explored and proposed. With low summer sea-ice area, energy to the Arctic Ocean is increased, which increases regional surface air temperatures and SSTs through autumn into winter. Positive temperature anomalies in the Arctic are likely to increase 500-hPa geopotential heights and surface pressures near Iceland and to reduce meridional temperature gradients between the pole and the subtropics. These effects lead to a weakened Icelandic Low, a weakened polar jet stream and a weak storm track. Therefore, increased summer sea-ice area is associated with the negative phase of the NAO.

Sea Ice: Physics and Remote Sensing addresses experiences acquired mainly in Canada by researchers in the fields of ice physics and growth history in relation to its polycrystalline structure as well as ice parameters retrieval from remote sensing observations. The volume describes processes operating at the macro- and microscale (e.g., brine entrapment in sea ice, crystallographic texture of ice types, brine drainage mechanisms, etc.). The information is supported by high-quality photographs of ice thin-sections prepared from cores of different ice types, all obtained by leading experts during field experiments in the 1970s through the 1990s, using photographic cameras and scanning microscopy. In addition, this volume presents techniques to retrieve a suite of sea ice parameters (e.g. ice type, concentration, extent, thickness, surface temperature, surface deformation, etc.) from space-borne and airborne sensor data. The breadth of the material on this subject is designed to appeal to researchers and users of remote sensing data who want to develop quick familiarity with the capabilities of this technology or detailed knowledge about major techniques for retrieval of key ice parameters. Volume highlights include: Detailed crystallographic classification of natural sea ice, the key information from which information about ice growth conditions can be inferred. Many examples are presented with material to support qualitative and quantitative interpretation of the data. Methods developed for revealing microstructural characteristics of sea ice and performing forensic investigations. Data sets on radiative properties and satellite observations of sea ice, its snow cover, and surrounding open water. Methods of retrieval of ice surface features and geophysical parameters from remote sensing observations with a focus on critical issues such as the suitability of different sensors for different tasks and data synergism. Sea Ice: Physics and Remote Sensing is intended for a variety of sea ice audiences interested in different aspects of ice related to physics, geophysics, remote sensing, operational monitoring, mechanics, and cryospheric sciences.

For decades, previous editions of John Knauss’s seminal work have struck a balance between purely descriptive texts and mathematically rigorous ones, giving a wide range of marine scientists access to the fundamental principles of physical oceanography. Newell Garfield continues this tradition, delivering valuable updates that highlight the book’s resourceful presentation and concise effectiveness. The authors include historical and current research, along with a 12-page color insert, to illuminate their perspective that the world ocean is tumultuous and continually helps to shape global environmental processes. The Third Edition builds a solid foundation that readers will find straightforward and lucid. It presents valuable insight into our understanding of the world ocean by: • Encompassing essential oceanic processes such as the transfer of heat across the ocean surface, the distribution of temperature and salinity, and the effect of the earth’s rotation on the ocean. • Providing sensible and well-defined explanations of the roles played by a stratified ocean, global balances, and equations of motion. • Discussing cogent topics such as major currents, tides, waves, coastal oceans, semienclosed seas, and sound and optics.

Over the past 20 years the study of the frozen Arctic and Southern Oceans and sub-arctic seas has progressed at a remarkable pace. This third edition of Sea Ice gives insight into the very latest understanding of the how sea ice is formed, how we measure (and model) its extent, the biology that lives within and associated with sea ice and the effect of climate change on its distribution. How sea ice influences the oceanography of underlying waters and the influences that sea ice has on humans living in Arctic regions are also discussed. Featuring twelve new chapters, this edition follows two previous editions (2001 and 2010), and the need for this latest update exhibits just how rapidly the science of sea ice is developing. The 27 chapters are written by a team of more than 50 of the worlds’ leading experts in their fields. These combine to make the book the most comprehensive introduction to the physics, chemistry, biology and geology of sea ice that there is. This third edition of Sea Ice will be a key resource for all policy makers, researchers and students who work with the frozen oceans and seas.
