Arctic Sea Ice Ecology
The book on sea ice ecology is the ecology of sea ice algae and other microorganism as bacteria, meiofauna, and viruses residing inside or at the bottom of the sea ice, called the sympagic biota. Organisms as seals, fish, birds, and Polar bears relies on sea ice but are not part of this biota. A distinct feature of this ecosystem, is the disappearance (melt) every summer and re-establishing in autumn and winter. The book is organized seasonally describing the physical, optical, biological, and geochemical conditions typical of the seasons: autumn, winter, and spring. These are exemplified with case studies based on author’s fieldwork in Greenland, the Arctic Ocean, and Antarctica but focused on Arctic conditions. The sea ice ecosystem is described in the context of climate change, interests, and effects of a decreasing summer ice extent in the Arctic Ocean. The book contains an up to date description of most relevant methods and techniques applied in sea ice ecology research. This book will appeal to university students at Masters or PhD levels reading biology, geosciences, and chemistry.
Ecology
This overview of evolutionary, behavioural, population, community and applied ecology covers the essentials required by beginning students. This edition has been thoroughly updated to reflect recent ideas, concepts and examples. It also features greater emphasis on applied ecology.
Atlas of Submarine Glacial Landforms
New geophysical techniques (multibeam echo sounding and 3D seismics) have revolutionized high-resolution imaging of the modern seafloor and palaeo-shelf surfaces in Arctic and Antarctic waters, generating vast quantities of data and novel insights into sedimentary architecture and past environmental conditions. The Atlas of Submarine Glacial Landforms is a comprehensive and timely summary of the current state of knowledge of these high-latitude glacier-influenced systems. The Atlas presents over 180 contributions describing, illustrating and discussing the full variability of landforms found on the high-latitude glacier-influenced seafloor, from fjords and continental shelves to the continen...
The Mechanical Properties of Sea Ice
The review discusses the state of thinking of each of the main national groups investigating sea ice and gives an overall appraisal of the field as a whole. Emphasis is placed on (1) the physical basis for interpreting sea ice strength (phase relations, air volume, and structural considerations), (2) theoretical considerations (strength models, air bubbles and salt reinforcement, and interrelations between growth conditions and strength), (3) experimental results (tensile, flexural, shear, and compressive strength, elastic modulus, shear modulus and Poisson's ratio, time dependent effects, and creep), and (4) plate characteristics. The paper includes a review of problems in sea ice investigations, relates the chemical, crystallographic, mechanical, and physical aspects involved, and concludes by showing how to utilize this knowledge to solve practical problems.

The Salinity Distribution in Young Sea Ice
Studies were conducted at North Star Bay (NW Greenland) during Oct-Nov 1956 to examine the lateral and vertical salinity variation in known types of natural sea ice. Sampling procedures and data analysis are described in detail. The data show that the standard deviation of the salinity values from closely spaced cored samples in sheet ice are always equal to or greater than!0.3%. In pancake ice, the standard deviation is usually!1.0%. This uncertainty will produce a standard deviation of approximately! 4 to 6% of the total brine volume in the sheet iceAND! ll to 19% in pancake ice. This accounts for a considerable portion of the scatter observed in studying the strength properties of sea ice. (Author).
Nights at the Circus
'Raunchy, raucous...a rich, turn of the 19th century world, which reeks of human and animal variety' The Times Is Sophie Fevvers, toast of Europe's capitals, part swan...or all fake? Courted by the Prince of Wales and painted by Toulouse-Lautrec, she is an aerialiste extraordinaire and star of Colonel Kearney's circus. She is also part woman, part swan. Jack Walser, an American journalist, is on a quest to discover the truth behind her identity. Dazzled by his love for her, and desperate for the scoop of a lifetime, Walser has no choice but to join the circus on its magical tour through turn-of-the-nineteenth-century London, St Petersburg and Siberia. **One of the BBC’s 100 Novels That Shaped Our World**
The Nordic Seas
" ... as soon as one has traversed the greater part of the wild sea, one comes upon such a huge quantity of ice that nowhere in the whole world has the like been known." "This ice is of a wonderful nature. It lies at times quite still, as one would expect, with openings or large fjords in it; but sometimes its movement is so strong and rapid as to equal that of a ship running before the wind, and it drifts against the wind as often as with it." Kongespeilet - 1250 A.D. ("The Mirror of Kings") Modern societies require increasing amounts influence on the water mass and on the resulting of scientific information about the environment total environment of the region; therefore, cer tain of its characteristics will necessarily be in whieh they live and work. For the seas this information must describe the air above the sea, included.
Geoheritage of Volcanic Harrats in Saudi Arabia
This book records the geoheritage values of globally significant, yet little-known, volcanic geosites in Saudi Arabia. It is the first of its kind to focus on the Middle East, clearly showing the hidden geoheritage value of the volcanic Arabian Peninsula’s harrats and demonstrating why the Saudi Arabian volcanic fields are unique. Along with the systematic geosite description, the book introduces scientifically founded geoeducational programs that can be used to develop our understanding of volcanic geoheritage values of volcanic fields. It offers a detailed and comprehensive research-based description of four of the most accessible volcanic harratts in Saudi Arabia and an additional summary of other more remote fields. Additionally, it discusses geoeducational programs that could be used to link these volcanic areas and use them in volcanic hazard education.
