Book Description
The BOREAS TE-1 team collected various data to characterize the soil-plant systems in the BOREAS SSA. Particular emphasis was placed on nutrient biochemistry, the stores and transfers of organic carbon, and how the characteristics were related to measured methane fluxes. The overall transect in the Prince Albert National Park (Saskatchewan, Canada) included the major plant communities and related soils that occurred in that section of the boreal forest. Soil physical, chemical, and biological measurements along the transect were used to characterize the static environment, which allowed them to be related to methane fluxes. Chamber techniques were used to provide a measure of methane production/uptake. Chamber measurements coupled with flask sampling were used to determine the seasonality of methane fluxes. This particular data set contains carbon dioxide and methane flux values from the SSA-OBS site. The data were collected from 09-Jun to 04-Sep-1994. The data are stored in tabular ASCII files. The data files are available on a CD-ROM (see document number 20010000884), or from the Oak Ridge National Laboratory (ORNL) Distributed Active Archive Center (DAAC).

Book Description
In a time when an unquestionable link between anthropogenic emissions of greenhouse gases and climatic changes has finally been acknowledged and * widely documented through IPCC reports, the need for precise estimates of greenhouse gas (GHG) production rates and emissions from natural as well as managed ecosystems has risen to a critical level. Future agreements between nations concerning the reduction of their GHG emissions will - pend upon precise estimates of the present level of these emissions in both natural and managed terrestrial and aquatic environments. From this viewpoint, the present volume should prove to a benchmark contribution because it provides very carefully assessed values for GHG emissions or exchanges between critical climatic zones in aquatic en- ronments and the atmosphere. It also provides unique information on the biases of different measurement methods that may account for some of the contradictory results that have been published recently in the literature on this subject. Not only has a large array of current measurement methods been tested concurrently here, but a few new approaches have also been developed, notably laser measurements of atmospheric CO concentration 2 gradients. Another highly useful feature of this book is the addition of - nitoring and process studies as well as modeling.

Book Description
Biometeorology in Integrated Pest Management is a resulting book from a conference with the same title held at the University of California in 1980. This book presents integrated pest management (IPM) in different viewpoints and perspectives. It serves as a helpful exchange of ideas to strengthen the research in integrated pest management. From a biometeorological viewpoint, the microclimate of agricultural systems is introduced in this book to describe the environment in which pests live. The first few chapters in this book discuss IPM in the perspective of biometeorology. Some of the topics include crop canopies (general heat exchange and wind movement), microclimate (instrumentation, techniques, and simulation), and microclimatic stress (remote sensing). The following section of the book focuses on plant pathology. The subject areas covered in this section include radiation quality and plant diseases; management of plant pathogens; and plant canopy modification and impact on plant disease. The last section focuses on weed science. The interaction of weeds to other pests, effects of light and temperature on weed growth, and weed seed germination are some of the topics discussed in this part. This book is a good source of reference to both students and professionals in the field of biometeorology, entomology, and agriculture. Other interested parties in the research of integrated pest management will also find this book helpful in their endeavors.

Book Description
Recent planetary missions by NASA, the European Space Agency, and other national agencies have reaffirmed that the geological processes which are familiar from our studies of Earth also operate on many solid planets and satellites. Common threads link the internal structure, thermal evolution, and surface character of both rocky and icy worlds. Volcanoes, impact craters, ice caps, dunes, rift valleys, rivers, and oceans are features of extra-terrestrial worlds as diverse as Mercury and Titan. The new data reveal that many of the supposedly inert planetary bodies were recently subject to earthquakes, landslides, and climate change and that some of them display active volcanism. Moreover, our understanding of the very origins of the solar system depends heavily on the composition of meteorites from Mars reaching the Earth and of rock fragments found on the Moon. Planetary Geology provides the student reader and enthusiastic amateur with comprehensive coverage of the solar system viewed through the eyes of Earth scientists. Combining extensive use of imagery, the results of laboratory experiments, and theoretical modeling, this comprehensively updated second edition (previously published in paperback and now available in hardback) presents fresh evidence that, to quote the first edition, planetary geology now embraces conventional geology and vice versa. *** " . . . a much improved version of what was already a good book. The new text is some 20 percent longer . . . color illustrations have been dispersed throughout . . . and the information presented is brought right up to the minute with numerous injections of new scientific results from the many space missions that have been conducted since the first edition appeared. Recommended." - Choice, Vol. 51, No. 07, March 2014~

Book Description
The BOREAS TF-4 team measured fluxes of CO2 and CH4 across the soil-air interface in four ages of jack pine forest at the BOREAS SSA during August 1993 to March 1995. Gross and net flux of CO2 and flux of CH4 between soil and air are presented for 24 chamber sites in mature jack pine forest, 20-year-old, 4-year-old, and clear cut areas. The data are stored in tabular ASCII files. Anderson, Dean and Striegl, Robert and Wickland, Kimberly and Hall, Forrest G.
