A Marine Mystery

This past weekend, I noticed the water had turned a rusty reddish color in the False Creek inlet near English Bay. The color change is difficult to see even with the naked eye, but it's definitely there. I've enhanced the reddish color in the following photograph so you can see. It seems I was the only one who noticed or cared about this unusual event while I was there. I was beside myself trying to come up with a logical explanation. My conclusion was that that the second angel of the apocalypse had blown his trumpet, and the end was nigh. 😅
