Book Description
This report documents a Fortran version of a chemical thermodynamic model for aqueous electrolyte solutions at subzero temperatures, FREZCHEM2, which is a further development of the FREZCHEM model. The model uses thermodynamic data of Spencer-Moller- Weare that permit the calculation of chemical equilibria in the Na-K-Ca-Mg-Cl-S04-H2O system between -60 and 25 deg. C at atmospheric pressure. It applies the Gibbs energy minimization method for chemical equilibrium computation combined with Pitzer equations for activity coefficients and water activity calculation. phases.

Book Description
Written by two of the best US researchers in the field, this text investigates issues of astrobiological relevance in the context of cold aqueous planetary geochemistry. At the core of the technical chapters is the FREZCHEM model, initially developed over many years by one of the authors to quantify aqueous electrolyte properties and chemical thermodynamics at subzero temperatures. FREZCHEM is of huge relevance to scientists in a number of fields, including biogeochemists.

Book Description
Cryosols – permafrost – occupy a unique part of the earth and have properties greatly different from other soils. They also occur where the greatest impact of global warming is predicted. This is the first book bring together the leading researchers in the area of permafrost soils to produce a review of the geography, cryogenic soil forming processes, ecological processes, classification and use of soils that are affected by permafrost.

Book Description
The year 2003 was the 50th anniversary of the seminal experiment of Stanley Miller. This was a unique opportunity for highlighting the current interest in this most interdisciplinary subject. The leading space agencies: the European Space Agency (ESA) as well as NASA, the American Space Agency, have planned missions that will elucidate some of the still unknown questions underlying research in the origin of life. New results are surpassing our ability to keep well informed: the reviews that we were presented at the Trieste meeting will bring the readers of this well-documented and timely book up to date in this fast-moving area. An important component of the conference was the review of the Cassini-Huygens mission due to arrive in the Saturn system just one year after the conference convened in Trieste. There was particular interest in the status of the experiments that will take place inside the atmosphere of Titan, the large satellite, which is a testing ground for the theories and experiments in the field of chemical evolution. The Jovian system is currently under study with the view of investigating the possibility of life underneath the frozen surface of the Galilean moon Europa; the ESA mission "Mars Express" and Mars Odyssey received special attention. Some of the world leaders in the field gathered in Trieste in September 2003 - that was a most timely date for reviewing recent data and discussing the prospects of future research.

Book Description
Covering more than seven percent of the earth’s surface, sea ice is crucial to the functioning of the biosphere—and is a key component in our attempts to understand and combat climate change. With On Sea Ice, geophysicist W. F. Weeks delivers a natural history of sea ice, a fully comprehensive and up-to-date account of our knowledge of its creation, change, and function. The volume begins with the earliest recorded observations of sea ice, from 350 BC, but the majority of its information is drawn from the period after 1950, when detailed study of sea ice became widespread. Weeks delves into both micro-level characteristics—internal structure, component properties, and phase relations—and the macro-level nature of sea ice, such as salinity, growth, and decay. He also explains the mechanics of ice pack drift and the recently observed changes in ice extent and thickness. An unparalleled account of a natural phenomenon that will be of increasing importance as the earth’s temperature rises, On Sea Ice will unquestionably be the standard for years to come.

Book Description
Sheds new light on the microbial ecology and physiology of the Earth’s polar regions. • Examines the microbial investigations during the International Polar Year of 2008 focusing on the Arctic and Antarctic, along with earlier investigations on critical environmental issues such as climate change, ozone depletion, and elemental cycling. • Offers a survey of what is known and unknown about the microbial inhabitants of polar environments, addresses the adaptations and physiology of cold-adapted microorganisms, and explores the ecological role that polar microbial communities play in biogeochemical cycling. • Presents the challenges that polar and subpolar microorganisms face and describes the lowest temperatures in which microbial life can exist—and the prospects for life on other planets. Recommended for a general microbiology audience as well as for scientists and students in all areas of biology and geomicrobiology.
