Pre-52 I'm pretty sure he could withstand the impact. As for New-52, Aquaman shed blood from assault rifles and high caliber bullets before so not sure what a nuke would be able do. However, he did take a heavy blow from Dead King who has shown to have superhuman strength beyond any other living being in the ocean including Aquaman.
Lol, it had to be the creator of Aquaman's daughter who asks the question. That was great! These people speaking bad of Aquaman can't swim nor do they live near water. And that is why they don't like Aquaman.
