The Trench Biosphere at the Bottom of the Ocean: Progress and Challenges provides a comprehensive and critical analysis of the trench biosphere, examining the geological and physiochemical constraints on trench microorganisms (bacteria, archaea, fungi) and fauna, along with their molecular adaptation mechanisms to extreme conditions. Edited by experts in the field, the book addresses the presence of emerging and legacy environmental pollutants in trenches, state-of-the-art technologies and devices for sampling and analysis, and introduces a big-data platform for curating biological, genetic, and natural product resources in hadal trenches. A necessary guide for students and researchers in the field of Environmental Science, this book provides the latest information on biological processes and the biological and genetic resources found in the deep ocean.
