Book Description
The Quaternary has been a period of major climatic and environmental oscillations, and our knowledge of these past variations is important for our understanding of the possible impact of human activity on the present-day environment. First published in 1999, Quaternary Climates, Environments and Magnetism presents an account of the rich variety of uses of magnetic measurements in the environmental geosciences. Ten chapters by leading world authorities describe the highlights of environmental magnetic work during the last decade and identify directions for future research. Emphasis is placed on a multidisciplinary approach to achieve a more thorough understanding of the environmental processes involved. This volume will be of interest to research scientists from a wide range of disciplines working on Quaternary environments, including earth and environmental sciences, physical geology, geography and palaeoclimatology. It will also be valuable as a supplementary text for graduates and advanced undergraduates.

Book Description
The Third International Symposium on Paleolimnology was held at the beginning of September 1981 in Finland. After registration at the University of 10ensuu and the opening session and welcome reception in the Town Hall, the participants moved to a hotel at Koli, a hill famed as a landmark and for its panoramic view. Here the lecture session, lasting four days, took place. Momentarily, the mosaic of the lakeland became visible between the clouds showing the hill slopes covered by mature spruce forest and scattered old birch trees, a reminder of the last slash-and-burn phase some 130 years ago. Altogether 120 paleolimnologists participated in the meetings and most also attended one of the two post-symposium excursions to the Arctic Circle and to South Finland. The lectures covered a wide range of paleolimnological subjects. The main topics, however, included current aspects in the dating of sediments and the history of eutrophication. The symposium was advised by the international organizing committee under the presidency of Professor Edward S. Deevey. Other members present at Koli were Dr. Maj-Britt Florin, Dr. Heikki Ignatius, Prof. Heinz Lamer, Prof. Gerbert Martinson and Dr. Magdalena Ralska-lasiewiczowa. They also gave direction to a discussion on future plans for international activity in paleolimnology. Later in the autumn, after the end of the symposium, the partici pants sent special thanks to the secretaries, Mrs. Eija Merilainen, Mrs. Tuula Nylander and Mrs. Anita Toukomaa, for solving individual problems during the symposium with smooth and rapid efficiency.

Book Description
The magnitude and causes of decadal to century-scale changes in climate are major issues of global concern. The separation of anthropogenically driven change from natural 'baseline' variability within the atmosphere/ocean system is a prerequisite to identifying human impact on global climate. An understanding of past climate variability is therefore a key to predicting future climate change. The sedimentary record of the oceans, seas and lakes is produced by a series of depositional events that occur on seasonal timescales but can rarely be resolved due to mixing of the sediment by bottomdwelling organisms. Where they are preserved, laminated sediments act like tree rings to record these seasonal-scale processes, such as plankton blooms and floods, and provide a uniquely high-resolution record of environmental change. In addition, annually laminated or 'varved' sediment sequences act as geochronometers against which other timescales can be tested. Laminated sediments may therefore be used to develop records of interannual and decadal-scale variability which serve to test models of climate change. The authors cover a range of topics that include strategies for study and techniques of analysis. A series of case studies, dealing with a variety of lacustrine and marine records, illustrates the wide potential of laminated sediments as palaeoclimatic and palaeoceanographic indicators.

Book Description
This handbook reviews the key palaeoecological methods applied to primarily organic lake and mire deposits. Particular attention is paid to Holocene environmental changes in the temperate zone, but most methods can be applied to older Quaternary deposits and to areas outside the temperate zone. The need for uniform methods of correlating stratigraphical data on a continental scale is emphasized.

Book Description
Methods in Paleomagnetism covers the proceedings of the NATO Advanced Study Institute on Paleomagnetic Methods, held in the Physics Department of the University of Newcastle upon Tyne on April 1-10, 1964. The book focuses on apparatus and techniques used in paleomagnetism and rock magnetism. The selection first offers information on sampling techniques in the field and measurement of natural remanent magnetization. Discussions focus on ballistic and spinner magnetometers; paleomagnetic sampling with a portable coring drill; portable apparatus for collecting small oriented cores; and portable field-sampling equipment. The book also takes a look at procedures to test the stability of magnetization, as well as physical properties of demagnetization; thermal demagnetization by the continuous method; and apparatus for thermal demagnetization by the progressive method. The text ponders on measurement of isotropic and anisotropic susceptibility and magnetic measurements in applied fields. Topics include preliminary account of a refined technique for magnetic susceptibility anisotropy measurement of rocks; errors in anisotropy measurements with the torsion balance; and measurement of the anisotropy of the susceptibility with an astatic magnetometer. The selection is a valuable reference for readers interested in paleomagnetism.

Book Description
This text, written by a leading researcher in the field, describes the origin and formation of lakes in order to give context to the question of how lacustrine deposits form. It explains the process of sedimentation in lakes and the chemistry of those deposits and describes how the age of lake deposits are determined. Additionally, this book shows how different groups of fossils are used in interpreting the paleontological record of lakes. In order to illustrate the more synthetic approaches to interpreting the history of lakes, the author also discusses such special topics as lake-level history, lake evolution, and the impact of environmental change on lakes.
