Geomorpic map of the Pacific

Abstract

Special points of the ocean floor geomorphological mapping are discussed. The map under consideration is drawn at the scale 1:15000000 using an original equal-area projection (by Verner-Murevskis) which facilitates areal measurements on the map. The map summarizes recent data on geomorphology, geology and geophysics. The map is based on the assumption of morphostructural control of the World Ocean floor topography, the classification of the Pacific floor relief being done in accordance with morphostructural principles. Morphostructures are subdivided into those of planetary and lower ranks. The legend consists of two large sections: morphostructures and morphosculptures. Main contents of the first section are four planetary morphostructures of the ocean floor and their main subdivisions. The second section of the legend includes various large and small landforms of the exogenous origin. The map's content is briefly discussed.
