Atlantic Meridional Heat Transport

North Atlantic Section: AX7

North Atlantic Section: AX7

High density XBT sections have been taken along tracklines from the Gibraltar Straits to the Straits of Florida (AX7) since 1995, with average spatial sampling of 30-40 km. These sections can be used to infer the heat transport in the subtropical North Atlantic. This page discusses quarterly estimates of meridional oceanic heat transport in the center of the North Atlantic Ocean subtropical gyre obtained from the data collected along this high-density line (AX7).
