Eddies Found to be Deep, Powerful Modes of Ocean Transport

*Study Finds Connection between Atmospheric Events and the Deep Ocean*

Researchers from Woods Hole Oceanographic Institution (WHOI) and their colleagues have discovered that massive, swirling ocean eddies–known to be up to 500 kilometers across at the surface–can reach all the way to the ocean bottom at mid-ocean ridges, some 2,500 meters deep, transporting tiny sea creatures, chemicals, and heat from hydrothermal vents over large distances.

The previously unknown deep-sea phenomenon, reported in the April 28 issue of the journal Science, helps explain how some larvae travel huge distances from one vent area to another, said Diane K. Adams, lead author at WHOI and now at the National Institutes of Health. (more…)

Expedition to Mid-Cayman Rise Identifies Unusual Variety of Deep Sea Vents

*Method included first use of Nereus hybrid vehicle in ‘autonomous’ mode*

The first expedition to search for deep-sea hydrothermal vents along the Mid-Cayman Rise has turned up three distinct types of hydrothermal venting, reports an interdisciplinary team led by Woods Hole Oceanographic Institution (WHOI) in this week’s Proceedings of the National Academy of Sciences.
