Because the surface of the ocean cools faster than the bottom, in addition the bottom has greater preassure so it freezes at a lower temperature, comething that doesnt happenin a glass of water where the preassure difference is minimal. Plus there are subsurface hot currents, so the two systems are not equivalent at all.

When the outside temperature falls below the freezing point of water, lakes and rivers get frozen. However, only the top layer of the lake or river freezes.
