Ocean fertilization refers to dumping iron (as powdered iron sulphate) or other nutrients (e.g. urea) into the ocean in areas with low biological productivity in order to stimulate phytoplankton growth. In theory, this would draw carbon dioxide out of the atmosphere as the phytoplankton grows, and then when it dies and falls to the ocean floor the carbon would be sequestered there for long periods of time.
