Methane, a powerful greenhouse gas, may be removed from the atmosphere by photocatalytic means, such as iron salt aerosols (ISA) of ferric chloride, and from water and soil by adding nutrients missing for methanotrophs (methane eaters). In water columns, such as the oceans, swamps or rice paddies, the supplementary nutrients may best be applied using the Buoyant Flakes method.

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.
Floating Seatomiser masts use wind turbine energy to spray seawater droplets of specific size ranges into the lower troposphere. Commercial spray nozzles are modified to work at higher tri-phasic pressures and to produce droplets for different purposes: coarse and medium sized ones to humidify air at different wind speeds, and baffle-conditioned, fine ones from flat fan spray nozzles to generate evaporating droplets that nucleate marine cloud and/or create sea salt aerosols (SSA).
