Storm Surges Can be Stopped at Sea!
The difference between a rough sea day and a storm surge day is the frequency of the waves. In either case, each wave pushes a large amount of seawater forward into a crest. At that point the individual drops of seawater fall back to their original location but the wave energy travels on. Neither the rough sea or the surge moves water more than a few meters. The surge comes when the next wave arrives before the previous wave's water can fully return to its original spot. If each 200 liter wave can only return 98% of its water home before the next wave, each wave will effectively be traveling above an extra 4 liters of sea level. At the shore this extra water piles up and eventually floods the area. As you can see above, gas released in water doesn't move a significant amount of water, and they wave created is in a circle. Releasing 1 ton of liquid nitrogen into the ocean while a storm surge is building would lead to the movement of 600 tons of seawater being replaced by the movement of gas. This would create a large channel of unsynchronized wave motion where the remaining waves could release their energy. Air Products could provide the gas for an experiment at one of the country's wave tanks. If successful, the proposed New York Harbor barrier would not be necessary.
