In this episode, we hear about a NOAA-funded study that asked an interesting question: what if mussels could be used to learn more about microplastic pollution in our waterways? NOAA already runs a program that monitors chemical contaminants in our coastal waterways and Great Lakes by sampling mussels and oysters called the Mussel Watch program. So wouldn’t it be great to tap into Mussel Watch to also learn more about plastics in our environment? Spoiler alert: the study didn’t turn out quite as expected. This is part one of a two-part episode.

D-Day, codenamed Operation Neptune, was the largest amphibious landing not only in World War II, but in history. It marked the start of the liberation of German-occupied France (and later western Europe) and laid the foundations of the Allied victory on the Western Front. But what most people don't know is that ocean tides played a crucial role in the initial phase of this historic day. In this episode, hear the story of D-Day from the perspective of the science of tides and tide predictions. We interview Greg Dusek, a physical oceanographer and senior scientist at the Center for Operational Oceanographic Products and Services, or CO-OPS — the tides and currents office of the National Ocean Service.

The ocean is home to millions of different forms of life—yet we know surprisingly little about the creatures that live right along our shores, how they interact with each other, or how they're changing as the ocean environment they live in changes. Hear how the U.S. Marine Biodiversity Observation Network aims to change that. The goal is to ensure that scientists not only notice changes in biodiversity at locations around the nation, but also have the tools in place to better understand what these changes tell us about ocean health over time.
