NOAA Ocean Podcast

Did you know many phrases that we use today have nautical origins? Lots of these terms derive from the Age of Sail — the period of time between the 16th and 19th centuries when masted ships ruled the seas.

In this episode, Kate Wheelock, Chief of NOAA’s Disaster Preparedness Program, explains how her team facilitates internal communication, coordination, and preparation for all types of unforeseen disasters.

Meteotsunamis occur all over the world — including the Great Lakes — but scientists are just beginning to better detect and understand them. In this episode, NOAA oceanographer Greg Dusek talks about new research that advances what we know about these little known, but surprisingly common, weather-driven events.

We interview a NOAA expert about ocean gliders — autonomous underwater vehicles used to collect valuable ocean data. In this episode, we uncover the technology behind gliders and dive in to what these vehicles can do to help prepare us for hurricanes.

In our latest podcast, Allison Wittrock, a cartographer with the Office of Coast Survey, tells us about NOAA’s new digital charts.

In this episode, Cindy Among-Serrao from Hawaiian Islands Humpback Whale National Marine Sanctuary talks about how citizen scientists help monitor and promote awareness about marine life — particularly humpback whales — during the annual Sanctuary Ocean Count.

In this episode, a NOAA ecologist discusses how invasive lionfish have become established across the Southeast U.S. and Caribbean. How did the fish get to the Atlantic? While the exact cause is unknown, it's likely that humans provided a helping hand. While NOAA researchers have concluded that invasive lionfish populations will continue to grow and cannot be eliminated using conventional methods, efforts continue to control populations.

This is the first half of a two-part interview with NOAA’s Hideyo Hattori. In this episode, we talk about the many ways that American Samoa is an amazing place, unlike anywhere else in the United States.

This is the second part of our interview with NOAA’s Hideyo Hattori about American Samoa. In this episode, we focus on Hideyo’s work with conserving the bountiful corals that surround the islands of this remote archipelago.

Harmful algal blooms (HABS) ... it's a term that many people became familiar with in 2018 due to a persistent "red tide" event along the Gulf Coast of Florida. In this podcast, we uncover what HABS are, what they aren’t, and how we can learn to minimize their effects on our daily lives.

With the use of unmanned systems, NOAA is reducing operational costs and manpower requirements, while increasing the type and quality of data that NOAA collects. In this episode, Rob Downs from NOAA’s Office of Coast Survey explains the past, present, and possible future of unmanned systems at NOAA.

Many marine organisms, including marine mammals, sea turtles, fish and invertebrates, rely on sound and hearing for their survival. Over the last century, increases in human activity within our ocean have led to increasing levels of noise. This increasing amount of noise from human sources is a rising concern for the health and well-being of marine organisms and ecosystems. In this episode, we talk with NOAA marine ecologist Dr. Leila Hatch about her work to better understand the ocean soundscape by developing programs that can establish baselines, detect changes in noise levels, and support the design of methods to reduce noise impacts.

Natural infrastructure provides effective solutions for minimizing coastal flooding, erosion, and runoff, but it has other benefits as well. In this episode, Kim Penn from NOAA’s Office for Coastal Management explains the environmental, economic, and recreational benefits of natural infrastructure.

June 1 is the start of the Atlantic hurricane season. Are you prepared? To help, learn the many ways the National Ocean Service responds to hurricanes, as well as easy steps you can take to be ready for whatever the season brings.

Understanding how the ocean moves is no easy task. In this episode, we hear from a NOAA oceanographer who studies the physics of how the ocean moves to better understand and predict how tides and currents shape our coastal environment.

How the gyres that circulate our ocean waters also accumulate plastics. Find out what a garbage patch is and isn't, and what we can do about this ocean-sized problem.

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.

Geodesy is a science that covers the Earth itself. It's the reason we know where we are, and how we can make maps of where we are and where we want to go. In this episode, learn how this science with an unfamiliar name shapes much of what we do every day.

In celebration of Native American Heritage Month, our latest podcast highlights NOAA efforts in partnership with native communities in Alaska to restore and protect precious ocean resources. In this episode, we learn just how challenging the issue of marine debris can be in the vast wilderness of Alaska, how the NOAA Marine Debris program is working to solve this problem, and how the key to beating this issue is in the innovation and ingenuity of the community working to address it.

It's time for a NOAA Ocean Podcast "Science Moment," where we sample the best segments from our past full-length podcasts. In this episode, hear about an effort called GPS on Bench Marks. A bench mark is a term used to describe any permanent mark or disk that's either in the ground or attached to a large structure. This permanent mark has a known elevation or height which makes it valuable to NOAA. There are over 400,000 bench marks in the United States, and in the GPS on Bench Marks project, anyone can visit the bench mark of their choice, record field notes, take digital photos, and collect GPS observations or coordinates and then use online tools to send the information to NOAA.

How NOAA scientists use marine biogeography—the study of marine species, the geographic distribution of their habitats, and the relationships between living organisms and the environment—to help locate the best sites to place potential future alternative energy sites in the ocean.

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.

What is ocean noise and what is NOAA doing to reduce this threat in our national marine sanctuaries? Many marine organisms, including marine mammals, sea turtles, fish and invertebrates, rely on sound and hearing for their survival. Over the last century, increases in human activity within our ocean have led to increasing levels of noise. This increasing amount of noise from human sources is a rising concern for the health and well-being of marine organisms and ecosystems. In this episode, we talk with NOAA marine ecologist Dr. Leila Hatch about her work to better understand the ocean soundscape by developing programs that can establish baselines, detect changes in noise levels, and support the design of methods to reduce noise impacts.

Listen in as we talk about coral reef health, specifically how reefs respond to stressful events like coral bleaching.

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. Tune in to this excerpt from a longer interview we posted back in March 2016 with NOAA social scientists Maria Dillard and Peter Edwards.

In this episode, we talk with a NOAA expert about how (and why) we forecast harmful algal blooms.

Money does not grow on trees, but it could be growing in our coastal salt marshes and sea grass beds. A team of researchers is working at Waquoit Bay Research Reserve on Cape Cod in Massachusetts on the "Bringing Wetlands to Market" project to study the connections between coastal wetlands, carbon dioxide uptake and storage, and the global carbon trading economy. Wetlands have the potential to serve as valuable assets in carbon trading markets – but only if we protect them, and don't dig up the treasure!

In this episode, we look back at a November 2014 archaeological expedition led by the Office of National Marine Sanctuaries Maritime Heritage Program. This mission brought back the first-ever 3-D images of the City of Rio de Janeiro, considered by many historians as the "Titanic of the Golden Gate." Listen in to this conversation with NOAA's Robert Schwemmer, co-leader of a two-year study to locate and document shipwrecks in California’s Gulf of the Farallones National Marine Sanctuary and the surrounding area.

Alaska—the largest and most remote state in the United States—is filled with wilderness and beauty, and unfortunately with marine debris. With a longer coastline than all the other U.S. states combined, Alaska finds itself with the greatest concentration of marine debris in our country. In this episode, we learn just how challenging the issue of marine debris can be in the vast wilderness of this state, how the NOAA Marine Debris program is working to solve this problem, and how the key to beating this issue is in the innovation and ingenuity of the community working to address it.
