They are the tracers that are used for measuring ocean circulation.

detecting leakages in pipes
Tracers may be used by biologists studying plants, engineers surveying flaws in metal, and doctors detecting medical problems.
tracer
Isotopes are used as tracers in many medical settings. Radioactive isotopes are used to identify abnormal bodily processes. The isotopes can also be used in plants to measure the amount of radioactivity in the leaves.
Carbon is an element, but not carbon dioxide. Carbon dioxide is a compound of carbon and oxygen.

Yes, tracers were in use during that time. The first tracers were developed by the British in 1915.

Isotopes as tracers can be easy to follow even if you are in low concentration and also by non-invasive(distructive) methods.

Tracer: A radioactive isotope that can be followed through the steps of a chemical reaction or industrial process.Two example of Tracers:1. tracers are used in finding weak spots in metal pipes and especially in oil pipes.2. Tracers injected into the body travel to organs and other structures where the chemical is normally used. this detects radiation.
