A wet suit loses buoyancy because the nitrogen gas used to make the bubbles in the foam neoprene compresses as depth and pressure increase. If you remember Boyl's law 50% of wet suit compression and buoyancy loss happens in the first 33 feet. The buoyancy loss becomes progressively less for every 33 feet beyond the first 33. Lets say a wet suit has 12 pounds on buoyancy on the surface, at 33 feet it would be about 6 pounds. At 66 feet it would be 3.9 pounds. At 99 feet it would be 3 pounds. At 132 feet it would be 2.4 pounds.
