My idea is to create a belt that attaches to a scuba suit that collects water samples to test the CO2 levels in the water before they are exposed to air, which may tamper with the results. This is to make sure that the water is a safe environment for all of the sea life down below!

The bottom of the vials collect the water sample, and the lids hold the solvent that test CO2 levels. Once a sample is collected, the cap is pressed down and the solvent is released into the water and the results can be revealed through the clear tubing.
