In Act 2, Scene 1. What is the significance of the speech in which Othello is reunited with Desdemona?

Othello arrives at last, and is very glad to see his wife arrived, much earlier than expected; he and Desdemona make public signs of their love, and then depart.

It gives me wonder great as my content To see you here before me. Oh, my soul’s joy! If after every tempest come such calms, May the winds blow till they have wakened death, And let the laboring bark climb hills of seas Olympus-high, and duck again as low As hell’s from heaven! If it were now to die, Twere now to be most happy, for I fear My soul hath her content so absolute That not another comfort like to this Succeeds in unknown fate.

Othello uses imagery from the sea.... the end of the storm and the calm (Desdemona) that comes with it.
