The international GEOTRACES program (https://www.geotraces.org/) is a marine geochemical project involving scientists from more than 35 countries that aims to improve understanding of trace elements and their isotopes in the marine environment (Anderson, 2024, in this issue). However, terms such as trace elements and isotopes can be very challenging concepts to communicate to a non-scientific audience. GEOTRACES scientists face this difficulty when explaining their research to the general public. To overcome it, the GEOTRACES International Project Office launched a series of short (about three minutes) educational videos aimed at introducing and explaining the science of the GEOTRACES program to the general public. These videos explain marine geochemical science and concepts such as trace elements and isotopes in an easy and fun format while keeping the scientific message accurate. They also constitute a powerful teaching resource and offer an accessible and appealing method for students to learn about marine geochemistry.
