The study presents the insights of the tectonic development and geological settings of the Atlantic Ocean supported by cartographic visualization in Generic Mapping Tools (GMT). The aim is to study geologic situation and trends in the tectonic development of the Mid-Atlantic Ridge and Atlantic Ocean seafloor. The objective is to find out impact of various factors (such as volcanic, tectonic, hydrothermal and sedimentary processes) that sculpt seafloor geomorphology, and correlation between early history of crust formation, geological processes and present submarine landforms. Other assignments in this work refer to mutual comparison of raster grids on sedimentation, topography, geology, seafloor fabric and highlighting similarities among the landforms and sediment thickness. Asymmetry in crustal accretion is explained by the tectonic history of the lithosphere formation. Correlation between plate subduction and development of the submarine landforms is explained by the Earth's crust extension resulting in formation of cracks, elongations, faults, rifts. Ocean seafloor geomorphology is shaped by a variety of factors that impact its form at different scales. These drivers (tectonic evolution, oceanic currents, hydrology, sedimentation) have effects on geomorphic landforms of the seafloor in context of historic geological development and during Quaternary. Technical part of this work was performed by GMT scripting toolset with all maps plotted in American polyconic projection. The results are received by overlay, cartographic analysis and synthesis of the multi-source geodata through mapping and interpreting grids (ETOPO1, EGM96, GlobSed, crustal age). This work contributes to expand the knowledge on geological and tectonic development of the Atlantic Ocean seabed in order to complete the view of its submarine geomorphology.

This university-level reference work covers a range of remote sensing techniques that are useful for mapping and visualizing benthic environments on continental shelves. Chapters focus on overviews of the history and future of seafloor mapping techniques, cartographical visualisation and communication of seafloor mapping, and practical applications of new technologies. Seabed mapping is referenced by high-resolution seismic methods, sidescan sonar, multibeam bathymetry, satellite imagery, LiDAR, acoustic backscatter techniques, and soundscape ecology monitoring, use of autonomous underwater vehicles, among other methods. The wide breadth of subjects in this volume provides diversified coverage of seafloor imaging. This collection of modern seafloor mapping techniques summarizes the state of the art methods for mapping continental shelves.

The explosion of interest, effort, and information about the ocean since about 1950 has produced many thousand scientific articles and many hun dred books. In fact, the outpouring has been so large that authors have been unable to read much of what has been published, so they have tended to concentrate their own work within smaller and smaller subfields of oceanog raphy. Summaries of information published in books have taken two main paths. One is the grouping of separately authored chapters into symposia type books, with their inevitable overlaps and gaps between chapters. The other is production of lightly researched books containing drawings and tables from previous pUblications, with due credit given but showing assem bly-line writing with little penetration of the unknown. Only a few books have combined new and previous data and thoughts into new maps and syntheses that relate the contributions of observed biological, chemical, geological, and physical processes to solve broad problems associated with the shape, composition, and history of the oceans. Such a broad synthesis is the objective of this book, in which we tried to bring together many of the pieces of research that were deemed to be of manageable size by their originators. The composite may form a sort of plateau above which later studies can rise, possibly benefited by our assem bly of data in the form of new maps and figures.

The study of the topography and structure of the ocean floor is one of the most important stages in ascertaining the geological structure and history of development of the Earth's oceanic crust. This, in its turn, provides a means for purposeful, scientifically-substantiated prospecting, exploration and development of the mineral resources of the ocean. The Atlantic Ocean has been geologically and geophysically studied to a great extent and many years of investigating its floor have revealed the laws governing the structure of the major forms of its submarine relief (e. g. , the continental shelf, the continental slope, the transition zones, the ocean bed, and the Mid-Oceanic Ridge). The basic features of the Earth's oceanic crust structure, anomalous geophysical fields, and the thickness and structure of its sedimentary cover have also been studied. Based on the investigations of the Atlantic Ocean floor and its surrounding continents, the presently prevalent concept of new global tectonics has appeared. A great number of works devoted to the results of geomorphological, geolog ical, and geophysical studies of the Atlantic Ocean floor have appeared. In the U. S. S. R. , such summarizing works as The Geomorphology of the Atlantic Ocean Floor [34], Types of Bottom Sediments of the Atlantic Ocean [24], The Geology of the Atlantic Ocean [38], and, somewhat earlier, Geophysical Studies of the Earth's Crust Structure in the Atlantic Ocean [13], have been published.

This book from the Peter Whitfield cartographic series traces the history of humankind's relation to the sea as revealed in ten centuries of maritime maps. Presenting sixty maps reproduced in color over double-page spreads, and commentary describing their special features and their significance in the history of navigation, the book explores ancient navigation; the Middle Ages and the Age of Discovery; the printed sea chart, 1600-1800; and the modern sea chart.
