NOAA Ocean Podcast

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 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.

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.
