Fertilizing the Oceans with Iron Sinks Carbon, But is it a Good Idea?

It’s a controversial idea that has been around for decades. Stimulate the growth of phytoplankton (plant plankton) in remote reaches of the oceans by fertilizing the oceans with iron. Previous studies concluded that such an approach would not be effective. However, the recent analysis of a 2004 ocean fertilization experiment in the Southern Ocean — [...]

Increased carbon dioxide availability alters phytoplankton stoichiometry and affects carbon cycling and growth of a marine planktonic herbivore

Biology / Marine Biology : Ocean Acidification (2 years ago)

Rising levels of CO2 in the atmosphere have led to increased CO2 concentrations in the oceans. This enhanced carbon availability to the marine primary producers has the potential to change their nutrient stoichiometry, and higher ca... Read Post

Iron fertilization less efficient for deep-sea carbon dioxide storage than previously thought?

Academics / General Science : Science Daily (4 months ago)

Scientists have discovered that iron fertilization promotes the growth of shelled organisms. In a naturally iron-fertilized system in the Southern Ocean the growth and sinking of these phytoplankton grazers reduces CO2 deep-ocean st... Read Post

International consortium formed to study fertilizing oceans with iron

Biology / Marine Biology : Fish & Aquatic News (4 years ago)

An international consortium has been formed to study the potential effects of adding iron to the ocean to promote the growth of phytoplankton. Read Post
