1. A method for increasing a depth of acidity in a body of seawater, comprising:
directing a flow of seawater from a first depth of the body of seawater through an electrolyzer configured to establish an electrical potential between a cathode and an anode, the flow of seawater passing through an anodic chamber and then a cathodic chamber;
transmitting electrical energy to the electrolyzer;
capturing hydrogen gas produced within the electrolyzer at the cathode;
capturing chlorine gas produced within the electrolyzer at the anode;
mixing the hydrogen gas and chlorine gas;
reacting the hydrogen gas and chlorine gas to produce a hydrogen chloride gas;
transferring the hydrogen chloride gas to a free surface of a water reservoir contained within an acid resistant chamber to produce a hydrochloric acid solution; and,
transferring the hydrochloric acid solution to a second depth of the body of seawater below said first depth.
