I read that page through, and didn't find it particularly compelling. Do you have anything that isn't 5 years old, and that doesn't try to talk around the issue by redefining terms?

What I mean is that when I think of when I would say "the ocean is dying," I'm referring to things like declining fish populations, coral reefs dying off, and the oceans themselves getting warmer and more acidic.

These things are undoubtedly happening. We have measured them, and we are causing it. Your link seems to say something like "the ocean isn't dying, because we still can do something about it." I'm not particularly concerned with this "ocean health index" they mention. I am not concerned with what we "can" do; I'm only concerned with what we are and will be doing. And, at this rate, what we are doing is not enough.

If you don't find the OHI (https://www.conservation.org/projects/ocean-health-index) credible, I'm not sure there's much more I could write that would convince you. Sorry :/

The point is that the oceans are large, there are different concerns, and conditions vary across location and species.

If you want to answer a question like "how healthy are our oceans?" you need to first work out what that might mean, and then measure that systematically like the project I linked you to.

Why do we need to attach a number to it for it to be a valid concern? The ocean is undoubtedly changing in ways that, if allowed to continue, will cause massive ecosystem damage, leading to secondary effects on land, such as increased warming and higher CO2 levels. Why is that not enough to convince anyone who matters to do anything?

There are lots of things being done, but much more could be done - and for that we need to convince governments, which takes data.

In particular we need to convince governing bodies that action is in their direct and immediate economic interest, which again takes data.

There is plenty of data. We've known this day was coming since the 1970's. Economic interests be damned, we need to do something now to avoid the collapse of civilization.
