Why do they put flight data recorders in water?


Why do they put flight data recorders in water? FDR's are water resistant, but they are not necessarily waterproof (particularly after a crash, which may puncture their casings or damage seals). If recovered from a crash in water, they are submerged in fresh, clean water to prevent deposits such as salt or minerals from drying out within the device.
