How does the ocean biome collapse?

I have a very broad question about the expected collapse of the ocean biome, and a bunch of related detail questions.

So first, the general question. I am kind of assuming that based on climate change, collapse of the coral reefs, overfishing, etc etc., that some time soonish the ocean biome is going to collapse. Where can I find resources online that outline how scientists / biologists project that this will play out?
If you are someone with specialized knowledge in this area - marine biologist, climatologist, ecologist, etc. - I'd like to hear your own prognosis and opinion for how this will play out, as well. Specifically:
Once it starts, does it snowball very rapidly? What is very rapidly? Does it go from plenty of fish to empty desert in a couple years? A couple decades?
What comes after? Does the ocean change chemically or temperature wise in such a way that fish life is completely wiped out? Or is it just that the carrying capacity is much reduced, and there are fewer / hardier species of fish?
Are there dramatic waves of change? Like for example, a few years of massive algae blooms that choke the oceans of O2, or some other species like jellyfish completely take over?
Do sea plants / seaweed survive in any numbers?
Does it eventually reach some new equilibrium, with a new ecosystem establishing itself? Or is the more likely case complete dieout?
Do you project anything else strange / interesting happening that I have failed to consider above?
