Book Description
The plasma background light in Thomson scattering measurements is often far higher than expected for a pure hydrogen plasma. The spectral distribution of light from three plasmas (duration: 1 ms to steady state; electron density: below 1012 to over 1014 cm−3; temperature: below 20 to over 1000 eV) and signal-to-noise and intensity data from the Thomson scattering systems used on them are compared with analytic estimates to show that in two of these plasmas molecular light dominates the spectrum, while in the other, molecular light is present, but bremsstrahlung is usually more intense. Knowledge of the mechanism for background light can aid in designing detection systems for Thomson scattering and provide information on the neutral species composition and effective charge of the plasma.

Book Description
The development of the laser and the subsequent expansion of research in the field of molecular scattering of light tend to ob scure the vast literature that accumulated on this subject during th'e last fifty years. The appearance of the Russian edition of Dr. Fabelinskii's book, just as this laser-induced explosion in light-scattering research took place, served to put the earlier work in its proper perspective. However, the book lacked any appreci able coverage of the laser work. Fortunately, Dr. Fabelinskii has taken advantage of the time between the appearance of the Russian text and its translation into English to expand greatly the sections devoted to areas in which laser research has made such interesting and vital additions, At the same time, revisions and insertions have been made throughout the text, so that the English translation is virtually a second edition of this useful work. The translator wishes to express his thanks here to Dr. Fa belinskii for making the revisions, corrections, and additions availahle for the English language work. He is also grateful to his graduate student, Mark B. Moffett, who prepared the index and who, during the course of its preparation, made a large number of crit ical comments and corrections that have enhanced the quality of the final product.

Book Description
Investigating Seafloors and Oceans: From Mud Volcanoes to Giant Squid offers a bottom-to-top tour of the world’s oceans, exposing the secrets hidden therein from a variety of scientific perspectives. Opening with a discussion of the earth’s formation, hot spots, ridges, plate tectonics, submarine trenches, and cold seeps, the text goes on to address such topics as the role of oceans in the origin of life, tidal bore, thermal effects, ecosystem services, marine creatures, and nutraceutical and pharmaceutical resources. This unique reference provides insight into a wide array of questions that researchers continue to ask about the vast study of oceans and the seafloor. It is a one-of-a-kind examination of oceans that offers important perspectives for researchers, practitioners, and academics in all marine-related fields. Includes chapters addressing various scientific disciplines, offering the opportunity for readers to gain insights on diverse topics in the study of oceans Provides scientific discussion on thermo-tolerant microbial life in sub-seafloor hot sediments and vent fields, as well as the origin of life debates and the puzzles revolving around how life originated Includes detailed information on the origin of dreaded episodes, such as volcanic eruptions, earthquakes, tsunamis, internal waves and tidal bores Contains information on the contribution of the oceans in terms of providing useful nutraceutical and pharmaceutical products
