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
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
Planktonic foraminiferal area density as a proxy for carbonate ion concentration: a calibration study using the Cariaco Basin Ocean Time Series
Biweekly sediment trap samples and concurrent hydrographic measurements collected between March 2005 and October 2008 from the Cariaco Basin, Venezuela are used to assess the relationship between [CO32-] and the area densities (?A) ... Read Post
International consortium formed to study fertilizing oceans with iron
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
