is it possible to form ice in seas(deep areas) and oceans by reasons that high pressure and low temperature?

Question

you know taht the termodynamic condition to form ice at standard conditioin is 1atm and -4 c but at deep water areas such as oceans or very deep areas in seas what ever we go down pressure increased and whatever pressure be high the tempreture to form ice so go high know i have a question in sea or oceans beds is there any ice ?

Answer 1

No. It is absolutely impossible, because ice crystals expand, and the high pressure of the ocean bottom would prevent this expansion, even at the north pole.

Answer 2

First, your premise is incorrect. Ice forms at 1 atm and 0 deg C. Moreover, water has an unique property that the freezing point DECREASES as the pressure increases. This is why we can ice skate (the pressure of the skate melts ice to form a pocket of slick water). As for the 4 deg C bit, this is the temperature at which the density of LIQUID water is at a maximum, which means that there is a tendency for this water to sink (in lakes that are not totally frozen, bottom water is at 4 deg C, while water at the surface of the ice is at 0 deg.). Of course, salt content may change the numbers somewhat, but the bottom temperature of the ocean tends towards 4 deg C, and at that temperature, the pressure will not compress the water into ice.

Answer 3

Ice melts when pressure is applied (as in ice skating) and the circulation of the ocean is going to guarantee that the water at the bottom never gets near freezing. Besides ice floats. If ice sank, what you are saying might happen, but then we could never iceskate.

Answer 4

If you could freeze High Density Water I think what you are saying is possible. It would not float and would remain on the bottom of the ocean. The problem is I don't think that type of water can freeze under normal enviormental conditions.
