XBT (eXpendable BathyThermographs)
transect AX07 is located nominally along 30oN extending from the Straits of Gibraltar in the eastern Atlantic to the east coast of the
United States at Miami, Florida. 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.
