Fluid activated retrieval device

A fluid activated retrieval device for retrieving an object from a fluidic medium comprising:

• a hollow base having a first cavity formed therein, wherein the hollow base includes,
• at least one port disposed along an outer surface of the hollow base, the at least one port configured to provide passage of the fluidic medium to the first cavity,
• a diaphragm disposed along the first cavity and proximate to the at least one port, the diaphragm configured to selectively allow the fluidic medium to enter the first cavity, and
• an anchor disposed along the first cavity for securing a line;
• a deployable float housing removably attached with the hollow base, the deployable float housing having a second cavity formed therein, wherein the deployable float housing includes,
• a buoyant chamber disposed along a distal end of the second cavity,
• a spool for receiving the line, the spool disposed within the second cavity and attached with the deployable float housing wherein the spool further comprises, a sealing flange disposed along the spool, the sealing flange arranged to seal the buoyant chamber from the second cavity;
• a winding stop disposed along an end of the spool;
• and
• a reactant disposed in the first and second cavities, the reactant responsive to the fluidic medium such that when the reactant comes into contact with the fluidic medium a reactant gas is generated.
