[LOTR] Is there any reason why the ring could not have been dumped in the ocean?

I feel it would be quite far from Sauron's grasp at the bottom of the sea.

"Then", said Glorfindel, "let us cast it into the deeps, and so make the lies of Saruman come true. For it is clear now that even at the Council his feet were already on a crooked path. He knew that the Ring was not lost for ever, but wished us to think so; for he began to lust for it for himself. Yet oft in lies truth is hidden: in the Sea it would be safe."

"Not safe for ever, " said Gandalf. "There are many things in the deep waters; and seas and lands may change. And it is not our part here to take thought only for a season, or for a few lives of Men, or for a passing age of the world. We should seek a final end of this menace, even if we do not hope to make one."

Sure dropping it in the ocean would prevent Sauron from getting the ring, for a time. But the ring wants to be found and it would eventually find its way back to Sauron's hand. Besides, the way things stood, Sauron's army would soon destroy Gondor, after that it wouldn't be long before the rest of Middle-earth was under his sway, then Sauron would have litterally all the time in the world to wait for the ring to get back to him or for him to find some way to retrieve it.
