- Listen up: What you need to know about ocean noise. (Episode 138) What is ocean noise and what is NOAA doing to reduce this threat in our national marine sanctuaries? 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.

- Bringing Wetlands to Market: the Power of Blue Carbon in a Changing Climate (Episode 137) 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! Episode permanent link and show notes
- Charting New Waters: Video Boaters rely on NOAA's nautical charts for depth measurements so they don't accidentally ground on sandbars or other underwater obstructions.

- Alaska: Marine Debris in the Wilderness (Episode 134) 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.

- Data Makes a Difference (Episode 133) Take a virtual journey to Penobscot Bay, Maine, to see how harbor pilots use U.S. Integrated Ocean Observing System (IOOS®) data for real-time ocean and weather conditions. This information is critical for safe navigation as pilots carefully move tankers and other vessels often carrying dangerous cargo safely in and out of port. IOOS coastal and marine data (e.g., water temperature, water level, currents, winds, and waves) are collected by many different tools including satellites, buoys, tide gauges, radar stations, and underwater vehicles. Most of the data collected are streamed online and viewable on digital maps for easy access.Episode permanent link and show notes
- Vertical Mapping and Atomic Clocks (Episode 132) 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.

- Arctic Shield (Episode 127) As sea ice continues to shrink in the Arctic, we’re likely to see more shipping, more oil exploration, more tourism, and more fishing. And all of this activity means that in the future, we’ll probably going have to deal with an oil spill in this remote region. So how do we prepare for that? The Coast Guard cutter Healy, a 420-foot-long icebreaker, is now heading north in answer to this question. The mission: an annual exercise called Arctic Shield led by the U.S. Coast Guard’s Research and Development Center. Onboard the Healy, scientists are gearing up to deal with a simulated oil spill in the icy Arctic. To tell us all about Arctic Shield and NOAA’s role in this expedition, we talk to Zachary Winters-Staszak, a spatial data specialist on the mission from the National Ocean Service’s Response and Restoration office.

- Where is Four Corners? (Episode 102) Have you ever been to Four Corners? It’s the only place in the U.S. where four states meet at one point. A few years back, there was some confusion over the position of a monument at Four Corners that marks this spot. Some reports claimed that the position of this marker was off by two and a half miles. Today, we’re revisiting a 2009 interview with Dave Doyle, chief geodetic surveyor from NOS’s National Geodetic Survey. As you’ll hear, Four Corners is exactly where it’s supposed to be — and the reason for that is that surveying isn’t only about taking precise measurements with sophisticated equipment, it's also about history, technology, and law.

Finally, we head out into the Pacific to point out some new ocean observing tools now available in Hawaii.
- Hypoxia in U.S. Coastal Waters (Episode 60) Earlier this month, a new interagency report was delivered to Congress that warns of the growing threat of low oxygen "dead zones" in coastal waters around the U.S. This condition is known as hypoxia -- where oxygen levels drop so low that creatures in the water are stressed or killed.
