NSRWA Watershed Ecologist and MassBays South Shore Coordinator , Sara Grady, has started recording podcasts through Marshfield Community Television that will cover multiple topics related to the estuaries of the South Shore and beyond.

Sara will also be accepting ideas for future topics. Just email your ideas to

Episode 6 – Blue Mussels and Shore Birds: In this episode we explore the role of blue mussels in the ecology of the coast, particularly as a food source for shorebirds migrating south. Blue mussels have been declining for decades, possibly due to invasive crab predation. Sara speaks to Callie Bianchi, a local resident who helped the NSRWA test the effect of mussel size on green crab predation efficiency, and Gina Purtell, who works with shorebirds at with shorebirds at MassAudubon.

  • Episode 5 – Salty Roads and Salty Streams: In this episode of our watershed ecologist’s podcast, The Estuarine Gradient, Sara discusses the impact of road salt on the environment. She talks to Scituate DPW Director Kevin Cafferty and Norwell DPW Director Glenn Ferguson about how road salt application has changed over the years to save money and reduce impacts to the environment while still keeping our roads safe.

  • Episode 3 – Bringing the Fish Back to Town Brook: Episode three discusses the restoration of Town Brook. Over the past 16 years the Town of Plymouth has worked with local, state, and federal partners to systematically remove dams and improve fish passage in Town Brook, which runs through the center of town. The final dam on Town Brook, Holmes Dam, is in the process of being removed, which will open up passage for river herring and eels from Cape Cod Bay to Billington Sea. In this episode, Sara talks to David Gould, Director of Plymouth’s Department of Marine and Environmental Affairs and Nick Wildman, Ecological Restoration Specialist from the Massachusetts Division of Ecological Restoration, about the Holmes Dam removal and the restoration of Town Brook as a whole.

  • Episode 2 – Sea Monsters: In the second Halloween-themed podcast “Sea Monsters” Sara and special guest Niels-Viggo Hobbs discuss mythological creatures, marine animals that are stranger than fiction, and the role of the ocean and it’s inhabitants in fueling fear in horror and sci-fi!

  • Episode 1 – Water Cycles: The introductory episode of “The Estuarine Gradient” covers basic estuarine vocabulary, the water cycle, drought and streamflow, stormwater pollution, and answers the question “What is up with those algal blooms in Florida?” Come for the review of some basic knowledge, stay for the “limiting nutrient” chocolate chip cookies.
