Explore the latest, uncharted realms of ocean science and conservation that you won't find anywhere else. Andrew takes you on an inspiring journey to uncover the hidden gems of oceanic discovery and initiatives. Tune in to discover how you can transform your life for a better ocean, one episode at a time. The How To Protect The Ocean is your resource to keep you informed on the latest ocean news; teach you how to speak up for the ocean; and, how you can take action to live for a better ocean. There is so much information on the ocean and the issues that are affecting it that it can be difficult to find optimism in the future of the ocean. Climate change, overfishing, plastic pollution, water pollution, and coastal development have altered the ocean in ways that have negatively changed the way we use it. The repercussions of climate change, including the ominous specter of rising sea levels, the relentless march of warming ocean temperatures, and the ominous shadow of ocean acidification, have not only altered the very fabric of our coastlines but have also conjured fie…","last_synced_at":"2026-09-26T08:23:21.814007+00:00","page_url":"https://stenobird.com/podcast/how-to-protect-the-ocean-2010"},"episode":{"title":"Blue Nitrogen: The Nutrient Story Coastal Wetlands Have Been Hiding","slug":"blue-nitrogen-the-nutrient-story-coastal-wetlands-have-been-hiding","published_at":"2026-09-14T07:00:00+00:00","page_url":"https://stenobird.com/podcast/how-to-protect-the-ocean-2010/blue-nitrogen-the-nutrient-story-coastal-wetlands-have-been-hiding","show_page_url":"https://stenobird.com/podcast/how-to-protect-the-ocean-2010","url":"https://www.speakupforblue.com/podcast","audio_url":"https://traffic.libsyn.com/secure/scicon/HTPTO_E2023_Adam_Langley_-_Wetland_Global_Nutrient_Change.mp3?dest-id=228444","summary":"Every time this podcast talks about coastal wetlands, the conversation goes straight to carbon. Marshes, mangroves, and seagrasses pull carbon dioxide out of the atmosphere and lock it in soil for centuries, and that story has earned coastal ecosystems a real seat at the climate table. Dr. Adam Langley, a global change ecologist and professor of biology at Villanova University and a research associate at the Smithsonian Environmental Research Center, thinks there's a second story hiding in that same soil that could matter just as much, or more: nitrogen. Langley and 37 co-authors just published the first global estimate of how much nitrogen the world's marshes and mangroves actually bury, and the number is staggering. Pulling from over 8,000 soil measurements across 255 tidal wetland sites worldwide, Langley's team calculated that coastal wetlands sequester roughly 3.2 teragrams of nitrogen every year, a figure Langley makes tangible by comparing it, loosely, to the mass of 700,000 African elephants or to the fertilizer applied to every cornfield in the United States. That's equal to somewhere between 13 and 15 percent of all the nitrogen buried in the world's oceans, a share nobody had managed to calculate on a global scale before this study. Nitrogen doesn't get the same climate spotlight as carbon, but its damage is intensely local: too much of it running off farmland and into estuaries fuels the algal blooms, oxygen dead zones, and red tides that can sicken and kill fish, manatees, and people. Coastal wetlands act, in Langley's words, like nature's kidneys, filtering that nitrogen out of the water and locking it away in oxygen-starved soil where it stays inert, as long as the wetland itself survives. And that's the catch. These wetlands have kept pace with sea leve…","meta_description":"Every time this podcast talks about coastal wetlands, the conversation goes straight to carbon.
