Seagrasses are plants that grow in semi salty water to full seawater in the intertidal and subtidal zones of the ocean. As one of the most productive ecosystems in the world, seagrasses offer myriad benefits to both humans and the organisms that call them home. In this episode, we explore some of the ecosystem services they offer.

Our ocean and coasts affect us — and we affect them. Almost 40 percent of the country’s population lives in coastal shoreline counties. And these counties contribute more than 9 trillion dollars to the U.S. economy. But there are many challenges facing our coasts, like climate change, sea level rise, more intense storms, and population growth. So we need to make good decisions today to help our coasts continue to thrive tomorrow. This is the third podcast in a three-part series from the U.S. Global Change Research Program that explores how we make these decisions. In this episode, a panel of government experts share their unique perspectives and experiences regarding the science of coastal decision making, and how the future could look if effective decision making is adopted.

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 economist about our ocean economy and how, no matter where you live in the United States, you are connected to our ocean economy.

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!

One hundred and four years ago this month, the RMS Titanic sank after striking an iceberg on her maiden voyage from the United Kingdom to New York City. In recognition of this tragedy, we present an interview with Jim Delgado, Director of Maritime Heritage with NOS's Office of National Marine Sanctuaries. This podcast is an excerpt from a special two-part podcast published in 2012.

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.

An effort to restore eelgrass beds along Virginia's eastern shore began with people painstakingly planting 200 acres of eelgrass seeds by hand. Today, these eelgrass meadows have grown to 6,195 acres — providing a home for an estimated 240,000 bay scallops!

Scientists at the National Institute of Standards and Technology, or NIST, are developing atomic clocks that are so accurate that the effects of the general theory of relativity come into play. That means if two of these clocks are at slightly different elevations—even a few centimeters—the higher clock runs noticeably faster. In this episode, find out why this is a problem for NIST, how the National Geodetic Survey helped to solve this problem, and how these amazing atomic clocks may someday play an important role in the science of geodesy. atomic-clocks.html">Episode permanent link and show notes
