60 Minutes on Coral Reefs and the challenge of depicting ocean acidification

This weekend's 60 Minutes featured this great segment on coral reefs, in which a well-protected "Gardens of the Queen" in Cuba are used a possible example of a resilient reef ecosystem.

The segment touches on coral bleaching, though perhaps not with the authority or depth that is warranted by science. What's most striking, however, is that the segment does not even mention ocean acidification.

I'm sure the media conspiracy theorists might claim this all as evidence a U.S. network shying away from discussing "controversial" subjects like climate change. But I suspect something else is at play, and it is something that science communicators everywhere need to consider. This is television - you need engaging, interesting video. Just how do you film ocean acidification? It's a slow, invisible process, nothing like the exciting action shots of the host and scientists diving among sharks and lionfish.

This is not a criticism - it is a challenge. What are the best ways for documentarians to capture the effect of changing ocean chemistry on coral reefs?
