The temperature in the Arctic Ocean is a constant 28o Fahrenheit (at least the last time I was there). Since it is constantly in motion, only water near the ice actually freezes.
Though the water temperature is constant, it can be monitored by satellite, ice camp manual temperature monitoring, submarines, and the occasional ice breaker headed north.
The temperature of the ocean at the surface is not constant across all oceans. For example, the Arctic Ocean will have a much colder surface temperature than the Pacific.
Either Arctic or Southern Ocean, depending on the season since temperature can affect the extent of ice in those oceans.

Temperature and the water its self are considered aboitic factors
The Arctic Ocean lies to the north of Europe and Asia.
The Arctic Ocean, because the North Pole is a spot on a sheet of ice floating on the Arctic Ocean, the water actually keeps the temperature higher. That is why the South pole is always colder than the North Pole.
