Antarctica iceberg SHOCK: Why are icebergs turning GREEN across Antarctica?

Glaciologists studying the phenomenon suspect significant amounts of iron oxide in rock dust from Antarctica’s mainland are trapped in the ice.

Iron oxide is a key element in the diet of phytoplankton, a microscopic plant-based organism, which forms various forms of marine bacteria and green algae.

Now, according to the UW study, the icebergs act like a delivery service of sorts, carrying iron oxide into those parts of the ocean where the element is scarce.

When the surface ice melts away from the iceberg, it releases the iron oxide which phytoplankton can then feed on.
