Substance floats on the surface a fluid when density of the substance is less than that of the fluid. When someone drowns and dies, the body starts to sink because the air in its lungs is replaced slowly with water thus increasing density. Once the body is submerged, its decomposition starts.
It remain submerged for some days until the bacteria in the gut and chest cavity produce enough gas(i.e,methane, hydrogen sulfide, and carbon dioxide). As the gas is light the body float back to surface of water.
