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.

Live From the Tropics, It’s an Ocean Network
With a click of his computer mouse, Scott Gallager was swimming with the fishes off the west coast of Panama. Virtual reality? Well, the fish, corals, and currents are real; […]

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.

Caught in the Middle of the Marine Mammal Protection Act
In the past few years, several research projects have been halted because of conflicting interpretations of the Marine Mammal Protection Act. Energy, shipping, and naval interests claim the MMPA hampers their ability to work in the sea. Environmentalists and animal rights want the act strictly enforced. In between are scientists.

One of the Greatest Volcanic Shows on Earth
About 50,000 years ago, a huge meteorite smacked into our planet, gouging a hole more than a mile wide and 790 feet deep in India. Of the roughly 150 known […]

What Brings the Food that Brings the Whales?
Watching the gray, pitching ocean from the beach in Barrow, Alaska, Carin Ashjian, a biologist at Woods Hole Oceanographic Institution (WHOI), wonders if the seas are too rough for the […]

Dust Busters for the Oceans
Like most living things, microscopic marine plants need iron and other minerals to live and grow. On land, soil provides a ubiquitous source of minerals, but how do essential nutrients […]

Analyzing Ancient Sediments at Warp Speed
Like a toy out of a science fiction story, the X-ray fluorescence core scanner reveals intimate details of the composition of ancient mud and sediment–which can contain a variety of clues about past climate and environmental conditions on Earth–without breaking the surface. In a matter of hours, the XRF simultaneously captures digital photographs and X-ray images of every millimeter of a core sample, while detecting the presence of any of 80 chemical elements.

Small Island. Big Ocean.
This week, more than 200 WHOI scientists and graduate students will brave the balmy trade winds, drooping palm trees, and misdirected laser pointers to present research in Honolulu. Reporters Hugh […]

An Ocean Warmer Than a Hot Tub
Scientists have found evidence that tropical Atlantic Ocean temperatures may have once reached 107°F (42°C)—about 25°F (14°C) higher than today. The surprisingly high ocean temperatures occurred millions of years ago […]

Float 312, Where Are You?
The ocean is so enormous, even a fleet of 2,338 ocean-monitoring instruments can sail into it and go largely unnoticed. That’s what floats 312 and 393 were doing until something […]

Under-ice Floats Offer a ‘Breakthrough’
The Arctic Ocean, home to fierce winds, punishing temperatures, and thick sea ice, is no place for wimpy people?or machines. So when WHOI physical oceanographers Peter Winsor and Breck Owens set out to explore the largely unknown currents beneath the polar sea ice, they had to design an instrument with true grit. (Fifth in a five-part series.)

The Flywheel of the Arctic Climate Engine
A key component of the Arctic climate clockworks is the Beaufort Gyre?a bowl of cold, icy, relatively fresh waters north of Alaska that is swept by prevailing winds into a circular swirl larger than the Gulf of Mexico.
