[What a weird question...] Why are you asking? Planning something? [SUSPICIOUS.]
But, eh... We are more durable than humans. I can stay in water that is -3 degrees. Eh, what is the word? It starts with a C. That temperature. Where I lived, was only little warmer.
If water were to freeze over... I do not know. Mermaids live all over, some even in coldest areas, where ice is. Suppose they have layer of blubber or something, like whales? For me, I do not know. Probably survive better in first form, than half-form or this human form.
