@Albright Not off hand, it is a well known fact I've heard repeated from many reliable sources. I've also been around chlorine enough to recognize it is a different smell.
With that said a quick google search produces several good sources confirming what I said.
Here is a good video on it by mark rover where he does the experiment to show that pee causes the smell (keep in mind you can find plenty of other sources if you want something more scholarly):
@Albright Skip to 4:11 if you want to see the part where they discuss how urine causes the pool smell, proper PhD making the claim too who is pretty much an expert on the topic.
