Researchers on an oceanographic voyage in the Arctic Ocean report, for the first time, baby walruses unaccompanied by mothers in areas far from shore and over deep water, where they likely could not survive. The phenomenon was coincident with movement of warm water into Arctic basins and subsequent melting of the sea ice that walruses normally utilize as resting platforms.

The Oceans Have Their Own Weather Systems

The Oceans Have Their Own Weather Systems

From June to September 2005, oceanographer Dennis McGillicuddy and a team of more than 20 scientists from WHOI and five other marine science labs tracked an eddy named A4. It was the oceanic equivalent of a hurricane?a huge mass of water, spinning like a whirlpool, moving through the ocean for months, stretching across tens to hundreds of kilometers, stirring up a vortex of water and material from the depths to the surface. But unlike destructive hurricanes, eddies are productive.

The Hunt for 18° Water

The Hunt for 18° Water

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.
