A swimmer wears a heavy belt to make her average density exactly equal to the density of water. Her mass, including the belt, is 60 kg. At a depth of 2 m below the surface of a pond, what buoyant force acts on the swimmer? What net force acts on her?

The total body of water. Think about it. Of you put oil in a glass of water, the oil will sink to the bottom. On the ocean, the oil will be pushed to the top. In a case like this, it's easier to think of the water as a solid being divided. If her average density were exactly equal to eh average density of the water, she would find herself in the middle... vertically speaking. Might take a while to get there though...

the oxygen in the swimmers lungs will effect buoyancy. This is how SCUBA divers control their buoyancy by breathing underwater.
