A A Balkema Publishers The Morphodynamics of the Wadden Sea
The Wadden Sea area of the North Sea is one which undergoes rapid morphological changes. Under natural conditions, the barrier islands would adjust them¬selves to a rising sea level. However, be¬cause the islands are densely populated and have an important role as holiday resorts, morphological changes are un¬desirable. Coastal engineering counter-measures have been undertaken to pre¬vent beach erosion, shifting of tidal in¬lets, breaching of dune ridges and land¬ward-directed washover. The natural processes and the results of human inter¬ference including the negative conse¬quences of many of the measures are discussed in detail. The author presents the current state of research, together with the results of his own investigations. In addition, a comprehensive description of the geomorphological development and recent problems of the barrier is¬lands from Texel to Fanø is given forthe first time. The book includes 40 colour photographs and 393 figures, almost all previously unpublished. Sat¬ellite and radar imagery as well as many aerial photographs are also included. The book is intended for geomorphologists, sedimentologists, environmentalists and all those with a scientific interest in tidal flats and barrier islands.

Springer-Verlag Berlin and Heidelberg GmbH & Co. KG The Ice Age
Nothing new from the Ice Age? Far from it! Barely ten years have passed since the first edition of this book was published, but in that time researchers around the world have developed new methods and published their findings in scientific journals. Consequently, ideas about the course of the Ice Age have changed dramatically. The sequence of the individual ice advances, the direction of ice movement and the direction of meltwater drainage are only partially known, but they can be reconstructed. This book offers in-depth information about the state of the investigations.Ice ages are the periods of the earth's history in which at least one polar region is glaciated or covered by sea ice. Thus, we are currently living in an Ice Age. The present Ice Age is also the period in which humans started to intervene in the shaping of the earth. The results are obvious. Aerial and satellite images can be used to trace the melting of glaciers, but also the decay of the Arctic permafrost, and the clearing of the Brazilian rainforest. This book is a translation of the original German 2nd edition Das Eiszeitalter by Juergen Ehlers, published by Springer-Verlag GmbH Germany, part of Springer Nature, in 2020. The translation was done with the help of artificial intelligence (machine translation by DeepL.com). A subsequent human revision was done primarily in terms of content, so that the book will read stylistically differently from a conventional translation. Springer Nature works continuously to further the development of tools for the production of books and promotes technologies to support the authors.

John Wiley and Sons Ltd The Ice Age
This book provides a new look at the climatic history of the last 2.6 million years during the ice age, a time of extreme climatic fluctuations that have not yet ended. This period also coincides with important phases of human development from Neanderthals to modern humans, both of whom existed side by side during the last cold stage of the ice age. The ice age has seen dramatic expansions of glaciers and ice sheets, although this has been interspersed with relatively short warmer intervals like the one we live in today. The book focuses on the changing state of these glaciers and the effects of associated climate changes on a wide variety of environments (including mountains, rivers, deserts, oceans and seas) and also plants and animals. For example, at times the Sahara was green and colonized by humans, and Lake Chad covered 350,000 km2 – larger than the United Kingdom. What happened during the ice age can only be reconstructed from the traces that are left in the ground. The work of the geoscientist is similar to that of a detective who has to reconstruct the sequence of events from circumstantial evidence. The book draws on the specialisms and experience of the authors who are experts on the glacial history of the Earth. Readership: Undergraduate and postgraduate students studying the Quaternary, researchers, and anyone interested in climate change, environmental change and geology. The book provides a rich collection of illustrations and photographs to help the readers at all levels visualise the dramatic consequences of glacier expansions during the Ice Age.
