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

Tracers may be used by biologists studying plants, engineers surveying flaws in metal, and doctors detecting medical problems.
The best known application is called carbon dating. Because of the influx of cosmic rays, the atmosphere contains a continually replenished supply of carbon 14. This isotope radioactively decays over a period of thousands of years. It is therefore possible to measure the carbon 14 content of objects and determine their age, up to a certain point, when the carbon 14 content has fallen to zero.
Radioactive tracers are useful in various fields such as medicine, industry, and environmental science. They help track the movement of substances in biological systems, monitor industrial processes, and study environmental pollution. By following the path of the tracer, researchers can gain valuable insights into different processes and make informed decisions.
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.
Ray Tracers happened in 1997.
The light-independent stage of photosynthesis, also known as the Calvin cycle, is where carbon dioxide is converted into glucose using the energy collected during the light-dependent stage. Radioactive tracers can be used to track the movement of carbon atoms through this process by marking them with a radioactive isotope like carbon-14. This helps scientists understand the flow of carbon and the rates of different biochemical reactions in the Calvin cycle.
Tracers like technetium-99m are used in medical imaging to diagnose conditions like cancer and heart disease. In environmental science, isotopes like carbon-14 are used to trace the movement of pollutants in ecosystems. Radioactive isotopes work as tracers because they can be easily detected using specialized equipment, allowing scientists to track their movement and behavior with high sensitivity and accuracy.
Ray Tracers was created on 1997-01-17.

Tracers - 2015 was released on: USA: 21 March 2015
Yes, tracers were in use during that time. The first tracers were developed by the British in 1915.
The cast of Tracers - 2010 includes: Nadia Nazir as Angela
The cast of Tracers - 2012 includes: George Justice as Large Man

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