Ocean World Update: Deep-sea Discovery Shines Light On Life In The Twilight Zone

by Keith Cowing

The ocean’s twilight zone is deep, dark, and — according to new research — iron deficient. No sunlight reaches this region 200 to 1,000 meters below the sea surface, where […]

Life In The Atlantic Ocean Thrives Due To Windblown Saharan Dust

by Keith Cowing

Iron is a micronutrient indispensable for life, enabling processes such as respiration, photosynthesis, and DNA synthesis. Iron availability is often a limiting resource in today’s oceans, which means that increasing […]

Oxygen Produced In The Deep Sea Raises Questions About Extraterrestrial Life

by Keith Cowing

Over 12,000 feet below the surface of the sea, in a region of the Pacific Ocean known as the Clarion-Clipperton Zone (CCZ), million-year-old rocks cover the seafloor. These rocks may […]
