The 3,000-float target set in 1998 was reached in November 2007, eight years after deployments began, after more than a hundred floats were put in the water during October alone. From this point the ocean's temperature and salinity — and therefore its density field, which is what drives the overturning — were measured globally and continuously for the first time.

A node is not a place. Drawing it on a map would assert something about the world that no stored fact supports.
