Noaa Ocean Podcast

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. Episode permanent link and show notes

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. Episode permanent link and show notes

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, learn about how coral reefs respond to stressful events like coral bleaching. Episode permanent link and show notes

Do you know the difference between a tide, a current, and a tidal current? Why (and how) do we study the motion of the ocean? Episode permanent link and show notes

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, learn about NOAA's historical map and chart collection of more than 35,000 scanned images. Episode permanent link and show notes

In our latest episode, we explore the history and work of NOAA's Commissioned Officer Corps--one of the seven uniformed services of the United States. NOAA Corps officers command NOAA's fleet of research and survey ships and also pilot NOAA's environmental data-gathering aircraft, including the agency's hurricane hunter planes. The NOAA Corps is celebrating a century of service to the nation this year, 2017. Episode permanent link and show notes

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, learn about marine animal telemetry, used to help scientist understand the ocean and marine life better. Episode permanent link and show notes

In today's NOAA Ocean Podcast, we talk about moving towards restoration at industrial waste sites. For more than a century, industrial activities have released hazardous chemicals and heavy metals into the environment. Both accidental spills and intentional discharges from chemical manufacturing, oil storage and transfer, ship building, and port operations have contaminated many of America's rivers and coastal resources. Join us as we talk with Reyhan Mehran from NOAA's Office of Response and Restoration about this topic. Episode permanent link and show notes

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 volunteering opportunities at one of our national marine sanctuary sites around the nation. Episode permanent link and show notes

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. Episode permanent link and show notes

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. Episode permanent link and show notes

In this episode, we talk with a NOAA economist about our ocean economy and how, no matter where you live in the United States, you are connected to our ocean economy. Episode permanent link and show notes

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! Episode permanent link and show notes
