Since 2007, NOAA’s National Ocean Service has been working to update the National Spatial Reference System. This huge project will modernize the system for measuring the horizontal positions and vertical elevations of the United States and its territories. During the course of this work, NOAA scientists realized that the heights of Colorado’s famous “Fourteeners” — or mountains with peak elevations of at least 14,000 feet — had been overestimated. In this episode, we learn why this occurred, how this impacts the status of these mountains, and what benefits this project will have for the nation. Our featured expert is Derek van Westrum, physicist with NOAA’s National Geodetic Survey. NOAA Ocean Podcast: Episode 79 -Moving Mountains

Marine debris is a large and global problem. Plastics, metals, rubber, fishing gear, and other lost and discarded items enter our ocean, Great Lakes, waterways, and coastal areas every day. This challenging problem can cause negative impacts to wildlife, the environment, and the economy. In this episode, we chat with our expert, Sophie Maginnes, communication specialist with NOAA’s Marine Debris Program. NOAA Ocean Podcast: Episode 78 - Marine Debris - Talking Trash

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.

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

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.

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.

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.
