Fish swimming in waters around Antarctica -- which is liquid -- enjoy water temperatures that are above freezing. Cold water on earth is home to many fish which thrive in cooler water.
The freezing cannot be stopped; only the freezing temperature is lowered adding salts.
They did not have to. Walruses do not live in Antarctica.
The frozen water, the below freezing temperatures, and the hard time of getting in and out of there.
Petrol used in Antarctica is usually jet fuel which possesses the lowest freezing point of any petrol with an operating range of -100°F (-73°C). There are also periods during which there is no use of petrol because the jet fuel is frozen.
The greatest danger in Antarctica is freezing to death by hypothermia.
In the winter, when the temps go below freezing, there should not be any water in a car. It should be antifreeze, actual windshield wiper fluid, etc.... This will prevent any freezing.
