The Atlantic has a mid-Atlantic mountain ridge, so the parabola effect is split into 2 basins with weaker concentration of sounds.<BR/><BR/>When the bottlenecked currents, ice sheets, tidal erosion and parabolic echo effects are combined with normal geotectonic activity along the Pacific rim, the sum shows up as displayed in the maps.<BR/>Also consider the accumulation of sonar and whale song carried long distances through seawater at various depths?DDedenhttps://www.blogger.com/profile/10033851770461086341noreply@blogger.com
