Studying Carbon Dioxide Absorption In Antarctic Seas Georgia Institute of Technology The seas around Antarctica can, at times, resemble a garden. Large-scale experiments where scientists spray iron into the waters, literally fertilizing phytoplankton, have created huge man-made algal blooms. Such geoengineering experiments produce diatoms , which pull carbon dioxide out of the air. Experts argue that this practice can help offset Earth’s rising ...

Carbon dioxide absorption in Antarctic seas Diatoms stuff more iron into their silica shells than they actually need. As a result, there’s not enough iron to go around, and the added iron during fertilization experiments may stimulate less productivity than expected. The study also says that the removal of iron through incorporation into diatom silica may be a profound factor controlling the Southern Ocean’s bioavailable pool of iron ...

Moving Iron in Antarctica Georgia Tech research published online Monday in Nature Communications indicates that diatoms stuff more iron into their silica shells than they actually need. As a result, there's not enough iron to go around, and the added iron during fertilization experiments may stimulate less productivity than expected. The study also says that the removal of iron through incorporation into diatom silica ...
