Patent ID: 8033879

Claim:
An apparatus for validating sequestration of fixed carbon in an ocean below the 100 year horizon, which comprises: a) a spar buoy with vertically elongate hollow body having a first end with superstructure and a second end with ballast mass, said hollow body having an upper fixed displacement volume V1 and a lower variable displacement volume V2; b) a horizontally disposed spaceframe suspended from said buoy at a depth at or below the 100 year horizon; c) an immersible instrument platform mounted on said spaceframe for measuring sedimentary deadfall as an index of carbon sequestration below the 100 year horizon of an ocean; d) a floating surface boom for enclosing around said buoy a surface area of said ocean; and e) a composition dispersed within said enclosed surface area, said composition comprising i) an inorganic nutrient formulation in an inorganic, sustained-release matrix, said composition having a net aggregate positive buoyancy.
