XBT (eXpendable BathyThermographs) transect AX04 is located nominally along 38oN extending from Straits of Gibraltar to the NE US coast. This latitude is ideal for monitoring heat flux variability in the Atlantic because it lies near the center of the subtropical gyre, which has been shown to be the latitude of the maximum poleward heat flux in the Atlantic Ocean.
