Abstract
Abstract The paper presents spatial analysis of the geological settings and topographic structure of the Pacific Ocean by Generic Mapping Tools (GMT). Its tectonic and geomorphic features have complex character and include, among others, trenches, ridges, East Pacific Rise, basins, fracture zones, rifts, rises, fault systems. Such topographic complexity results in the variability of the seafloor fabric and sedimentation reflecting correlations between the tectonic geomorphic markers and bathymetry. The methodology of this paper is based on the advanced cartographic toolset GMT which utilizes a shell scripting approach using a variety of modules. The tectonics showed strong correlation with the seafloor topography, and weaker correlation with sedimentation, which is influenced by geomorphology, gravity anomalies and bathymetry. The paper contributes to the oceanographic and geologic studies of the Pacific Ocean and methodology of GMT.
