Ocean Fertilization for Sequestration of Carbon Dioxide from the Atmosphere

摘要: The ocean is a major sink for both preindustrial and anthropogenic carbon dioxide. Both physically biogeochemically driven pumps, termed the solubility biological pump, respectively Fig.5.1) are responsible majority of sequestration in ocean’s interior [1]. pump relies on circulation – specifically impact cooling upper at high latitudes enhances dioxide density waters which to great depth (the so-called deepwater formation) thereby sequester form dissolved inorganic (Fig.5.1). by availability preformed plant macronutrients such as nitrate or phosphate taken up phytoplankton during photosynthetic fixation. A small but significant proportion this fixed sinks into settling particles, order maintain equilibrium from atmosphere transferred across air–sea interface drawdown) decreasing atmospheric (Fig.5.1).Fig.5.1
