This book presents the geological evolution of the Baltic Sea area since its inception, i.e., from the Late Glacial to the present day. The geological history of all evolutionary stages of the Baltic Sea is discussed in detail, from the Baltic Ice Lake, through the Yoldia Sea, Ancylus Lake, Littorina Sea and Lymnaea Sea, to the Mya Sea as the modern stage of the Baltic Sea development. The author presents palaeoecological and palaeosedimentological analyses of various evolutionary stages of the Baltic Sea. Detailed paleogeographic maps of the development of the Littorina Sea, Lymnaea Sea and Mya Sea are displayed, with particular focus on the Polish Baltic Sea area. Moreover, characteristic geological cross-sections and synthetic stratigraphic profiles representing individual areas of the Polish Baltic Sea coast are also shown. Each transgressive cycle of the various developmental stages of the Baltic Sea is characterized in terms of the average rate of marine transgression, the fluctuation of Baltic levels and the average rate of marine abrasion of the then cliff and spit shores, as well as the evolutionary changes of the area. In addition, the lithostratigraphic characteristics of the various marine sediment complexes and dune sediments (brown dune spits, yellow dune spits, light yellow-grey dune spits and grey dune spits) are also presented. Individual chapters address key aspects of:

• Litho-stratigraphical analysis of the Baltic Ice Lake deposits.
• Litho-stratigraphical analysis of the Yoldia Sea deposits.
• Litho-stratigraphical analysis of the Ancylus Lake deposits.
• Paleogeography, litho-stratigraphy and transgressive cycles of the Littorina
Sea.
• Paleogeography, litho-stratigraphy and transgressive cycles of the Lymnaea
Sea.
• Paleogeography, litho-stratigraphy and transgressive cycles of the Mya Sea.
• New stratigraphic division of the southern Baltic deposits along the Polish
coast.

The book will be useful for students and scientists of marine geology, oceanography, geography and environmental engineering. It will also be of practical use for all specialists dealing with marine basins and coastal zones, including marine geologists, coastal geologists and geomorphologists, geographers, as well as engineering geologists, geotechnicians and civil engineers. The book is generally related to the discipline of marine geology, and deals directly with the Baltic Sea basin.

Leszek J. Kaszubowski is a scientist in section of Engineering Geology and Hydrogeology from the Department of Geotechnical Engineering, West Pomeranian University of Technology in Szczecin, Poland. He graduated from Gdańsk University in 1979 achieving the title master of science, specializing in geomorphology and marine geology. The final examination of the doctor’s thesis took place in March 1988 at the Maria Curie-Skłodowska University in Lublin. Since 1985, he has been an academic teacher and researcher in Department of Geotechnical Engineering in Technical University of Szczecin and since 2009 in West Pomeranian University of Technology in Szczecin. He is working in engineering geology and also in coastal and marine geology. Since 1995, he has been a leader of the Polish Working Group of the International Research Program (IGCP-Project 367- Late Quaternary coastal records of rapid change). In the Commission on Genesis and Lithology of the Quaternary Deposits, Quaternary Research Committee, Polish Academy of Sciences, He is also an active member. In the Polish Society of Friends of Earth Sciences in Szczecin, he is the President of this organization, and also belongs to the Polish Geological Society, Szczecin Division. In the international scientific activity, he is an active member of Coastal Education and Research Foundation, in Coconut Creec, FL, USA. His scientific interests are connected with several research areas, including the geological studies of the coastal zone and seabed of the Baltic Sea, where he uses the high resolution seismic and seismoacoustic techniques, and in applied sciences an engineering-geological and hydrogeological studies for building constructions and environmental engineering. He recently published two scientific chapters (2016, 2018) in the books of Springer International Publishing as a part of the Coastal Research Library series.
