Deep-sea study reveals iron limitations in ocean's twilight zone

Los Angeles CA (SPX) Sep 26, 2024

New research has shed light on the ocean's twilight zone, a region between 200 to 1,000 meters below the surface where iron deficiency limits the growth of bacteria. These microorganisms compensate by producing siderophores - molecules that help them scavenge trace amounts of iron from seawater. "Understanding the organisms that facilitate carbon uptake in the ocean is important for unders
