The Gakkel Ridge in the Arctic Ocean is the slowest spreading portion of the global midocean ridge system. Total spreading rates vary from 12.8 mm yr−1 near Greenland to 6.5 mm yr−1 at the Siberian margin. Melting models predict a dramatic decrease in magma production and resulting crustal thickness...
