- Perspectives on Coastal Decision Making Our ocean and coasts affect us — and we affect them. Almost 40 percent of the country’s population lives in coastal shoreline counties. And these counties contribute more than 9 trillion dollars to the U.S. economy. But there are many challenges facing our coasts, like climate change, sea level rise, more intense storms, and population growth. So we need to make good decisions today to help our coasts continue to thrive tomorrow. This is the third podcast in a three-part series from the U.S. Global Change Research Program that explores how we make these decisions. In this episode, a panel of government experts share their unique perspectives and experiences regarding the science of coastal decision making, and how the future could look if effective decision making is adopted.

- Water Level Stations and their Role in Tsunami Detection Tsunamis pose a threat to our nation’s coastal communities and can have devastating impacts to lives and property. These powerful forces of nature can be caused by events like earthquakes, landslides, and even volcanic activity like the January 2022 eruption in the Tonga Islands region. Although they can’t be stopped, detecting and monitoring these waves when they occur can help warn the public of possible danger. In this episode, we speak with Paul Fanelli, Lead Oceanographer for NOAA’s National Ocean Service, Center for Operational Oceanographic Products and Services to learn how water level stations provide critical data to help issue alerts, and about the unique wave caused by the Tonga eruption.

- The Microplastic-Mussel Connection: Part Two In this episode, we continue our conversation with two NOAA scientists about a study that looked at using mussels as "biomonitors" to measure microplastic pollution in the Great Lakes. Here, they discuss how their study was set up and how the scientific method works. Amy and Ed also discuss how unexpected results are often part of the scientific process, and how conducting a study in the field with living organisms ist so challenging. This is part two of a two-part episode. Episode permanent link and show notes
- The Microplastic-Mussel Connection: Part One 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. Episode permanent link and show notes
- From Diving to Data: Close-up with Coral Research Coral reefs are among the most valuable ecosystems on Earth. Unfortunately, they are declining due to manmade and natural threats. NOAA’s National Coral Reef Monitoring Program (NCRMP) is a massive, collaborative effort that was developed to collect scientifically sound, geographically comprehensive biological, climate, and socioeconomic data in U.S. coral reef areas. In this episode, we speak with Shay Viehman, a Research Ecologist with NOAA’s National Ocean Service in the National Centers for Coastal Ocean Science, and a contributor to the NCRMP, to learn how NOAA divers turn the data they collect from underwater missions into usable summaries that help scientists study and protect U.S. coral reef ecosystems.

- Turning the Tide: D-Day from an Oceanographer's Perspective 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.

- Dealing with Dead Zones: Hypoxia in the Ocean When water runs off of farmland and urban centers and flows into our streams and rivers, it is often chock-full of fertilizers and other nutrients. These massive loads of nutrients eventually end up in our coastal ocean, fueling a chain of events that can lead to hypoxic "dead zones" — areas along the sea floor where oxygen is so low it can no longer sustain marine life. In this episode, we're joined by NOAA scientist Alan Lewitus to explore why dead zones form, how the problem of hypoxia is growing worse, and what we're doing about it.

- Arctic Shield As sea ice continues to shrink in the Arctic, we’re likely to see more shipping, more oil exploration, more tourism, and more fishing. And all of this activity means that in the future, we’ll probably going have to deal with an oil spill in this remote region. So how do we prepare for that? The Coast Guard cutter Healy, a 420-foot-long icebreaker, is now heading north in answer to this question. The mission: an annual exercise called Arctic Shield led by the U.S. Coast Guard’s Research and Development Center. Onboard the Healy, scientists are gearing up to deal with a simulated oil spill in the icy Arctic. To tell us all about Arctic Shield and NOAA’s role in this expedition, we talk to Zachary Winters-Staszak, a spatial data specialist on the mission from the National Ocean Service’s Response and Restoration office.

- Great Pacific Garbage Patch The Great Pacific Garbage Patch is one of many areas in the ocean where marine debris naturally concentrates because of ocean currents. In this episode, an expert from the NOAA Marine Debris Program explains what a garbage patch is and isn't, what we know and don't know, and what we can do about this ocean-sized problem.

- The Exxon Valdez, 25 Years Later Prior to the Deepwater Horizon spill in the Gulf of Mexico, the Exxon Valdez was the largest spill to ever occur in U.S. coastal waters. In this episode, we talk with NOAA marine biologist Gary Shigenaka to find out how marine life is faring today in Prince William Sound, Alaska. We also look at lessons we might learn from this environmental disaster in light of growing oil exploration and shipping traffic in the Arctic. Episode permanent link and show notes
- Connecting the Dots: Corals and Humans Coral reefs are under intense pressure from climate change, pollution, and unsustainable use. So what can we do about it? To answer that question, we need to better understand the main threat to our reefs. Humans.
