About this book

This book compiles research on the largest ice-free expanse on the Antarctic continent, representing the coldest and driest desert on this planet. The lack of liquid water and the delicate balance between gains and losses of organic carbon makes the McMurdo Dry Valleys ecosystem one of the most sensitive indicators of environmental change on our planet. "Ecosystem Dynamics in a Polar Desert" presents information from the primary abiotic forces defining the system, and from the present hydrology, biogeochemistry and physics of major sites of organic carbon production of the McMurdo Dry Valleys. Additionally, research on the physical, chemical, and biological properties of the dry valley soils is included. The critical role of environmental management in long-term ecological studies is also addressed in this volume. The accompanying CDROM provides details and scale to engage the reader in visualizing the McMurdo Dry Valleys from an ecosystem perspective.
