The high dissolved CO2 concentration at the ocean bottom is primarily caused by downwelling.

Here's a step-by-step explanation:

1. Downwelling is a process where surface water moves down into deeper parts of the ocean. This can be caused by changes in temperature or salinity, which increase the density of the water, causing it to sink.

2. The surface water contains CO2, which it has absorbed from the atmosphere.

3. As the water moves down into the ocean, it brings this CO2 with it.

4. Therefore, areas of the ocean where downwelling occurs can have high concentrations of dissolved CO2.

5. While bacteria, whales, and fish all contribute to the carbon cycle in the ocean, they are not the primary cause of high dissolved CO2 concentrations at the ocean bottom.

6. And mermaids, being mythical creatures, do not contribute to CO2 levels in the ocean.
