The average depth of the Arctic Ocean is 3,240 feet (987 meters).1

While this figure represents the average depth of the entire basin, the ocean's topography is complex and characterized by significant variations. It is divided into two principal deep basins—the Eurasia Basin and the Amerasia Basin—by the Lomonosov Ridge. These basins contain various subbasins with depths that differ substantially from the overall average; for example, the Fram Basin reaches a depth of 14,070 feet, while the Canada Basin has an average depth of 12,500 feet. The deepest sounding recorded in the Arctic is 18,050 feet (5,502 meters).21
