Jeff Kanney (left) and Derek van Westrum prepare to calibrate gravity meters in the high altitudes west of Boulder. Gravity and height are critical to mapping where water will flow.
Understanding Gravity

The National Geodetic Survey has been measuring land to determine points on the ground and the angles, distances, and heights between them since the 1800s. To do this accurately, you have to understand the force of gravity. We talk with a NOAA geodesist to understand what gravity is, why and how it changes, and what it means for NOAA.

A graduate student at the Waquoit Bay National Estuarine Research Reserve documents information gathered from a chamber set up to measure carbon dioxide and methane exchange within the marsh.
Bringing Wetlands to Market

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!

The Nurdle Patrol: Citizen Scientists Fight Pollution, One Pellet at a Time

Nurdles are small plastic pellets that are causing a big problem. But citizen scientists are fighting back. In this episode, learn how the Nurdle Patrol is taking on these problematic pellets, and how you can get involved.

NOAA aerial imagery from Youngstown, Florida, showing a “help” sign made out of trees. A Florida family awaiting assistance after Hurricane Michael was discovered after the sign was photographed by a National Geodetic Survey aerial team and then viewed by a family member.
After a Hurricane Hits: NOAA’s Emergency Response Aerial Imagery

Since the early 1900’s the National Geodetic Survey has been taking photographs from airplanes to capture the Earth below. We talk with two NOAA experts about their role in emergency response imagery collection after hurricanes, and what it provides for the public.

Print shows congestion of horse-drawn carts and wagons overburdened with merchandise on Dock Street, also handcarts, teamsters and longshoremen, and railroad locomotives and cars for hauling goods from ships to markets, includes many wholesale buildings and a transportation terminal, and the masts of many ships docked along the waterfront.
Ahoy! Top 10 Nautical Phrases Explained

Did you know many phrases that we use today have nautical origins? Many phrases that we use today derive from the Age of Sail — the period of time between the 16th and 19th centuries when masted ships ruled the seas. In this episode, podcast host Abby Reid shares the origins of 10 commonly used phrases.
