Gravity-derived crustal thickness models were calculated for the North Atlantic Ocean between 76 degrees N and the Chain Fracture Zone and calibrated using seismically determined crustal thickness. About 7% of the ocean crust is < 4 km thick (designated as thin crust), and 58% is 4-7 km thick (no...
