In this episode of Simply Science, we delve deep into the fascinating world of acoustic thermometry research in the Arctic Ocean. With its rapidly changing environment, the Arctic serves as a crucial focal point for understanding climate change and ocean dynamics. We explore how scientists are using sound to measure ocean temperature and track changes in water mass structure and sound speed profiles in response to thinning ice, warmer waters, and human activities.

We’ll also discuss the challenges researchers face, from harsh ice conditions to logistical hurdles, as well as the technological advancements that are making this critical work possible. From impacts on climate models and ocean circulation to the broader ecological consequences, join us as we uncover why the Arctic is more than just a frozen frontier—it's a key to our understanding of Earth's future climate.
