Deep thoughts from the Deep Blue Sea

The sea is a deep blue, so clear that you might think it was devoid of life. We have seen only a few seabirds circling the ship and playing in the air currents we generate. We haven’t seen any whales or sharks, only an occasional flying fish taking to the air in front of our bow wake. In this apparent desert, microbial life is king.

Upsala Glacier, Argentina, where scientists collected glacial dust samples. When glaciers move across bedrock, they scrape against it (see glacial grooves in the foreground), and grind it into smaller particles, which may then get blown out to sea. The turquoise blue water of the lake in the background is caused by the milkiness of the fine glacial dust suspended in it.  (Elizabeth Shoenfelt)

Iron Chemistry Matters for Ocean Carbon Uptake

An interdisciplinary team of scientists has discovered that, contrary to general scientific belief, iron in nondissolved particle form can stimulate phytoplankton growth, and that the chemical form that particulate iron takes is critical to ocean photosynthesis.
