Cylinder of water 70 miles in radius and 25 feet deep. Cool from 90 F
to 70 F,

(pi)(112.65 km x 10^5)^2(7.62 meters x10^2)(11.11 C) -- 3.38x10^18

Ice covered lakes and rivers only have a relatively small layer of ice
on top. You only need to lower the temperature for a shallow upper
layer.

So how the heck are you going to cool a thin layer of water in seas being
churned by hurricane force winds mixing the water up? (Not to mention
the fact that unlike ice, the cooler water will be more dense and tend
to sink)
