NOAA Ocean Podcast

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.
