Probably. But, it won't be pleasant (or so i heard from people who almost drowned) and there's quite considerable chance of failure if your body has positive buoyancy or if you get spotted.

There are things you can do to improve your chances of success (like diving into the ocean in the middle of winter). But as stated above, it will be long and unpleasant and you could be spotted.
