Yes. I mean, that's happening. Some of the CO2 automatically ends up in the ocean, which reduces the burden for the atmosphere. But what you probably meant is if we can artificially increase the CO2 dissolved in sea water. The answer is no. The CO2 in seawater is relative to the concentration in the atmosphere. If you add more to the atmosphere, you add more to the ocean. If you remove it from the atmosphere, you reduce the amount in the ocean.
