In 1959, oceanographer Valentine Worthington gave a name and an identity to a long-observed but poorly understood phenomenon of the North Atlantic. Valentine described how the interior of the Sargasso Sea contained distinct parcels of water with remarkably constant salinity, density, and temperature?roughly 18? Celsius. Decades later, his successors from Woods Hole Oceanographic Institution and eight other institutions have launched a far-reaching program to examine the formation and evolution of Worthington?s famous water and how it might influence North Atlantic climate.
