It's not QUITE so clear-cut. The ocean has a huge variability. For one thing, the solubility of oxygen in water varies depending on the temperature, pressure, and salinity of the water, so you'll see different amount of oxygenation at different depths and different locations. For another, there's lots of life in the ocean both using and replenishing the oxygen, so there are many zones of varying content.
A good example of this has been in the news recently - algal blooms have completely consumed all the oxygen in small regions of the ocean, creating 'dead zones' that kill all animal life that finds itself trapped within. Eventually the dead zones are filled in, but there can alway be more blooms, too!
Below is a link with very good charts showing a lot of these variations. Near the surface, there's typically about 6 mL of dissolved oxygen per L of water, but it can vary widely from there!

It's pretty low, with a minimum of only about .14%. That's .0014 liters of dissolved O2 per 1 liter of water.

It's very low
