Long-term Environmental Change in Arctic and Antarctic Lakes

About this book

Concerns about the effects of global climate change have focused attention on the vulnerability of circumpolar regions. Long-term historical data are needed to better understand the magnitude and direction of environmental change related to both natural and anthropogenic causes, as well as to assess patterns of natural variability. The paucity of instrumental data requires that proxy methods be used. The abundance of lakes throughout the Arctic and Antarctic makes paleolimnological approaches especially powerful tools to assist interpretations of environmental change.

This book provides a synthesis of the broad spectrum of techniques available for generating long-term environmental records from circumpolar lakes. It also provides overviews of the geographic extent of paleolimnological work completed thus far in these regions. It explores the diverse ways in which paleolimnology is used to address the pressing and emerging environmental issues of high-latitude regions. By providing both an introduction and in-depth reviews, this volume is of interest to students and advanced researchers alike who are studying earth, atmospheric and environmental sciences.
