Pumps that blow air or circulate water around structures or boats to keep ice from forming are known as

• A. Bubblers
• B. Heaters
• C. Deflators
• D. Sprayers

Answer: (A)

Preventing ice buildup around structures or boats is done by creating movement in the water near the surface. When air is blown underwater or water is circulated continuously, bubbles and currents disrupt the formation of a solid ice layer and keep the surface from bonding to the structure. This bubbler system keeps a channel open or a sheltered area accessible by constantly stirring the water just below the ice, which is essential for operations in icy conditions. Heaters melt ice by adding heat but aren’t the same as a pump-based tactic that maintains open water; deflators and sprayers don’t provide the active circulation needed to prevent new ice from forming around the hull or pilings.
