Synopses & Reviews
Published by the American Geophysical Union as part of the Antarctic Research Series, Volume 59.
The complex relationship between climate and lake level, the role of permanent ice covers in regulating lake ecology and sedimentation patterns, the character and function of microbial communities, the nature and distribution of dissolved organic matter, and the origin of brine composition are among the diverse range of topics addressed in this volume on the dry valley lakes of Antarctica. Readers will find that, far from being exotic limnological curiosities, these bodies of water are settings in which processes and problems of general scientific interest can be effectively investigated. Geochemists, hydrologists, biologists, oceanographers, limnologists, and students of these subjects will find much of interest in these pages. The papers included here move the discussion of the dry valley lakes well beyond the merely descriptive toward a richer exploration of physical and biogeochemical processes.
