At Cape Point - Looking Down at the Atlantic Meeting the Indian Ocean

I peered hard and long to spot the 'line' where the Atlantic washes into the Indian Ocean. I did not spot one, of course. I also wondered if the waters of the two were different. And they are!

As we drove down to beaches a few kilometers on either side of cape Point, we found the water of the Indian Ocean distinctly warmer (there being a perfectly geographical explanation) and cleaner. Maybe that was just our patriotism working up. Or maybe the beach was actually neater and cleaner for other reasons.
