Great shots, I only wish we had blue sky and sun here at the moment :o)
The technique I use is while the lens/lens port is dry cover it with plenty of saliva, this helps form a thin water membrane over the lens once you take the camera/camera housing out of the water to take the shot.
For best results keep the camera/camera housing immersed in the water until the very last few seconds before you take your shot, the lens/lens port should then have a nice clear water membrane form over it which will get rid of those water droplets from your photos.
There are other methods like rubbing sliced potatoe and rainx on the lens, I have had no joy with either of these, all the best.
Cheers

The first decent photo I took using the saliva on lens method - Fiji 2008
