Study Finds Deep Ocean is Source of Dissolved Iron in Central Pacific

A new study led by scientists at the Woods Hole Oceanographic Institution (WHOI) points to the deep ocean as a major source of dissolved iron in the central Pacific Ocean.

Newly discovered ocean plume could be major source of iron

Scientists have discovered a vast plume of iron and other micronutrients more than 1,000 km wide billowing from hydrothermal vents in the South Atlantic Ocean. The finding, published in the journal Nature Geoscience, calls past estimates of iron abundances into question, and may challenge researchers’ assumptions about iron sources in the world’s seas.

Lost City pumps life-essential chemicals at rates unseen at typical black smokers

Hydrocarbons—molecules critical to life—are routinely generated by the simple interaction of seawater with the rocks under the Lost City hydrothermal vent field in the Atlantic Ocean. The production of such building blocks of life makes Lost City-like vents strong contenders as places where life might have originated on Earth, according to research led by the University of Washington and the Woods Hole Oceanographic Institution.
