Adding nutrients to the ocean to promote the growth of phytoplankton, allows them to absorb more carbon dioxide through photosynthesis, thereby sequestering carbon, increasing albedo & oxygenation, and enhancing the marine food web.

Buoyant flakes made largely from waste materials ultra-slowly release nutrients in continently-remote surface waters to turn the dark blue seas turquoise with phytoplankton and increasing its albedo and that of marine cloud that cools the planet enough to offset current warming
Disseminating long-lived, ultra-slow-release, Buoyant Flakes carrying supplementary nutrients over the ocean surface mirrors what good farmers do on land. The flakes are made mainly from plentiful natural and waste materials using simple baking technology. They are designed to provide the iron, phosphate, silica and trace elements most needed by phytoplankton and seaweed to flourish.
