Iron fertilization is a Carbon Dioxide Removal (CDR) technique that would mimic this natural system, artificially adding iron to the ocean’s surface to stimulate growth of phytoplankton. The oceans are often naturally fertilized by dust storms like this one in 2003, which covered a vast swath of the Atlantic Ocean with a plume of iron-rich ...
Jan 3, 2020 · January 3, 2020. Iron-rich dust launched into the air by winds swirls around the Southern Ocean. Understanding how iron’s chemistry shifts during its journey from earth to air to sea will be ...
Iron fertilization is the intentional introduction of iron -containing compounds (like iron sulfate) to iron-poor areas of the ocean surface to stimulate phytoplankton production. This is intended to enhance biological productivity and/or accelerate carbon dioxide (CO 2) sequestration from the atmosphere. Iron is a trace element necessary for ...

Nov 13, 2007 · Laboratory experiments suggested that every ton of iron added to the ocean could remove 30,000 to 110,000 tons of carbon from the air. Early climate models hinted that intentional iron fertilization across the entire Southern Ocean could erase 1 to 2 billion tons of carbon emissions each year—10 to 25 percent of the world’s annual total.
Dec 19, 2019 · The iron ocean. Through dust, not rust, the metal plays a complex, controversial role in Earth’s climate. One brisk day in April 2013, as he drove with colleagues along the southern coast of Patagonia, Mike Kaplan spotted a geologist’s treasure trove — an active gravel pit with freshly exposed walls. He pulled over, grabbed the backpack ...
Feb 17, 2020 · The researchers studied the interactions between phytoplankton, iron, and other nutrients in the ocean that help phytoplankton grow. Their simulations suggest that on a global scale, marine life has tuned ocean chemistry through these interactions, evolving to maintain a level of ocean iron that supports a delicate balance of nutrients in ...
