Topography of the Aleutian Trench south-east off Bowers Ridge, Bering Sea, in the context of the geological development of North Pacific Ocean

The research is focused on the topographic modelling and mapping of Aleutian Trench. study area situated in Bering Sea, a marginal sea located northernmost Pacific Ocean, between Alaska Kamchatka Peninsula. geological setting region characterized by subduction oceanic Plate below continental North American Plate. Other features include high seismic activity along island arcs bordering seafloor. objective this paper to explore interaction geophysical affecting relief seafloor using geoinformation techniques analysis. In hypothesis study, variations fields as independent variables are reflected morphology seafloor, which can be observed data visualization advanced cartographic scripting solutions. open source high-resolution map (ETOPO1), marine free-air gravity Bouguer anomaly were used integrated investigate potential correlation geophysical, geological, tectonic settings Sea. Our main method includes bathymetric with publicly available GMT. Materials data: ETOPO1 raster grid 1 arc-minute resolution, EGM96 vector contour layers included complex thematic region, including topographic, contour, geodetic mapping, 3D geomorphological plotting 30 cross-section segments trench SE off Bowers Ridge. According processed dataset, minimal depth -8480 m mean -3089.154 m. geoid undulations model shows that majority values lie interval -10 20 lowest trench. statistical histogram most common value segment Trench -4800 m, occurring 1722 times. profile linear trend was done four different approaches regression (y = f(x) + e) weighted least squares (WLS) arguments: 1) m2t bt (polynomial degree one); 2) m3t ct2 two); 3) m4t dcos2?*t esin2?*t Fourier series 4) additional residuals. Surface performed xyz from ASCII enlarging fragment towards tested functionality modules GMT presented an effective toolset enabling precise modelling. contributes more detailed understanding Ocean bathymetry, specifically selected near Ridge area.
