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.

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.

Not all reefs in the ocean are naturally occurring. Artificial reefs are human-made structures that come in a variety of shapes and sizes. In this episode, we learn about what they are, the benefits they provide, and how the first study was conducted to calculate how much of the seafloor is covered by these reefs.

Rip currents pose a threat to those that spend time in the ocean or Great Lakes. In this episode, Dr. Gregory Dusek, senior scientist with NOAA’s National Ocean Service, talks with us about rip currents, NOAA’s national rip current forecast model, and ways to protect yourself and others from this public safety risk.

Gliders are autonomous, uncrewed, underwater vehicles that collect data — providing scientists with a more complete picture of what is happening in the ocean and the Great Lakes. In this episode, we dive deep with Kathleen Bailey, glider program manager with NOAA’s U.S. Integrated Ocean Observing System, to learn more about these versatile vehicles. less

In this episode, we present a podcast from the U.S. Army Corps of Engineers (USACE) called Engineering with Nature®. The show features a panel of experts discussing their research on how blue carbon is helping to address climate change. less

Seagrasses are plants that grow in semi salty water to full seawater in the intertidal and subtidal zones of the ocean. As one of the most productive ecosystems in the world, seagrasses offer myriad benefits to both humans and the organisms that call them home. In this episode, we explore some of the ecosystem services they offer.

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.

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.
