very interesting! could someone explain why the hot water would lead to deep, cold water being brought to the surface? I thought hot water is less dense than cold water. Wouldn't it just sit on the surface for a long time?

Or is there just such a large amount of this extremely hot water that the mixing overtime generates movement across the board?

I think it's that, as the lava sinks to the ocean floor, it warms the colder, nutrient rich water at depth and causes it to rise.

Exactly this. Warm water is less dense than cold water and "floats" over it. The volcano has created a temporary nursery for fishes basically.

The lava is pouring into the deeper cold water and causing it to rise. At least that’s how I read it.

oh yeah that makes more sense i misread it as water but they meant lava. woops
