This book presents the study of limnogeomorphology, in which past
proxy data such as lacustrine sediments with information on
landform development can be linked to modern observed data acquired
by instruments, including hydro-geomorphological and sedimentary
data. Traditionally, in the field of earth sciences, it has been
thought that geophysical studies dealing mainly with the present
process were not smoothly linked to geological studies that
originated from historical studies. Although such earth-surface
process studies are closely related to those on historical landform
development in the field of geomorphology, they have been studied
separately. Those two geomorphology studies correspond to process
geomorphology (dynamic geomorphology) and historical geomorphology.
There have been some attempts to combine them; however, they lacked
past quantitative records available for further analyses. In the
study of limnogeomorphology, proxy data can be converted to
quantitative information to be utilized in future environmental
discussions. This book also covers information not only on large
lake-catchment systems, but on small systems. Those include
long-term and short-term and large-scale and small-scale
environmental changes in east Eurasia such as Lake Baikal, Lake
Khuvsgul, Lake Biwa, and small lakes in Japan, Mongolia, China, and
Korea.

This book examines relationships between climate-hydrological
changes and other phenomena including land use and natural
disasters during the Holocene and recent past. In particular,
periods of rapid climatic shifts such as global warming and global
cooling are examined through paleohydrological and other studies of
various lake-catchment systems in East Asia, from Mongolia in the
north to Taiwan in the south. A number of different research
techniques are used in the work presented here, including sediment
analysis and optically stimulated luminescence dating and the
reader learns how the lake-catchment system functions as a "proxy
observatory" for past and present environmental monitoring. The
lake catchments studied by the authors of this volume are under
similar climatic conditions, i.e., under the East Asia monsoon,
with some systematic difference in climatic factors. Both proxy and
observation data are available for the surrounding countries'
provisions against natural disasters that are related to
climate-hydrological events and readers will see how present
instrumental observation data can be connected to past proxy data
(sediment information) in the system.
Lake Baikal in eastern Siberia is a crucial site for detecting
long-term global changes, owing to its high sensitivity to climatic
oscillation and its extraordinarily long history. Because
lacustrine sediments have an advantage in providing high-resolution
information, the sediments in Lake Baikal contain excellent
continuous records of past conditions including paleoclimates,
evolution, and specification of organisms. Based on the study by
the Baikal Drilling Project, this book provides information on
global climatic and environmental changes for as much as 12 million
years. The book also includes discussions of comparatively
short-term changes such as glacial and interglacial transitions
that directly link to the present and future environment. Long
Continental Records from Lake Baikal summarizes the latest
knowledge on the paleoenvironment and provides a foundation for
further studies in global environmental changes.
