Eyes on Earth Episode 137 – Landsat Takes Yellowstone’s Temperature

The Yellowstone National Park area has more than 10,000 thermal features. And while Old Faithful is a pretty predictable geyser, some thermal features can change quite a bit. New ones can even pop up! Remote sensing provides a tool for monitoring them—especially the thermal infrared sensors (TIRS) on Landsat 8 and Landsat 9 satellites. In this episode of Eyes on Earth, R. Greg Vaughan, the remote sensing lead for the Yellowstone Volcano Observatory, describes what causes the thermal features and how he uses Landsat and other remote sensing data to track their locations and estimate their temperatures. Then Terry Sohl, the Integrated Science and Applications Branch chief at USGS EROS, describes a couple of other important uses of Landsat thermal data.

Steamboat Geyser — Sounds of Yellowstone (ASMR, Sleep, Concentration)

Need time to concentrate or relax? Then listen to the gurgling and bubbly sounds of Steamboat Geyser in Yellowstone National Park, Wyoming. "Steamboat Geyser is the world’s tallest active geyser. It showers watchers and drenches the walkway. Days, months, or years pass between the major eruptions of Steamboat Geyser. Steamboat Geyser’s major eruptions (more than 300 feet high) are unpredictable and often many years apart. Its frequent “minor phase” eruptions eject water 10 to 40 feet high." (-NPS.gov) If you're looking for the video, check out Steamboat Geyser on the USGS YouTube channel.

Eyes on Earth Episode 132 - Moving Forward with AI at EROS

Eyes on Earth tackles artificial intelligence (AI) in a 2-part episode. AI is quickly becoming a necessary part of geospatial work at EROS, helping us efficiently do science to better manage our world. In Part 1, we talked about AI’s current and upcoming impact on our work at EROS and clarified some of the AI jargon. The successful use of AI to make NLCD an annual product was a key example. In Part 2, we discuss another potential application of AI—keeping Landsat satellites safe and healthy in orbit. Additionally, guests comment on how readily staff are adapting to using this rapidly evolving technology. They discuss the biggest benefits and challenges we face in using AI. Among the benefits are making EROS data products more accurate and reliable and getting them to the public in a more timely fashion.

Eyes on Earth Episode 131 – Using AI in Geospatial Work

Eyes on Earth tackles artificial intelligence (AI) in a 2-part episode. AI is quickly becoming a necessary part of geospatial work at EROS, helping us efficiently do science to better manage our world. In Part 1, EROS Director Pete Doucette discusses AI and its current and upcoming impact on our work at EROS. To help clarify AI terminology such as machine learning, deep learning, neural networks, transformers, and foundation models, we also talk to scientists who are using AI. And we learn about how AI enabled the National Land Cover Database (NLCD) to become an annual product. Part 2 will discuss one more potential application of AI—keeping Landsat satellites safe and healthy in orbit. We also have all of our guests comment on AI’s challenges and benefits.

Beryl Spring — Sounds of Yellowstone (ASMR, Sleep, Concentration)

Need time to concentrate or relax? Then listen to the natural sounds of Beryl Spring in Yellowstone National Park, Wyoming. Beryl Spring, in the Gibbon River valley south of Artist's Paintpots, is a complex plumbing system in Yellowstone National Park with a strongly and constantly boiling hot spring pool, and a powerful fumarole just behind the pool. If you're looking for the video, check out Beryl Spring on the USGS YouTube channel.

Eyes on Earth Episode 134 – Data Accuracy: The Calibration and Validation of Landsat

Landsat is the longest-running, continuously operating record of Earth observations, and it’s the gold standard reference point that other civil and commercial satellite programs trust. If a researcher is studying multiple Landsat images of the same spot on Earth, and there is something in those images that suggests a change, that researcher needs to have the confidence that that change is a real change on the landscape and not because of something that changed or degraded in the sensor. Think of it this way. We are using a system to quantify changes on the Earth—we need to make sure the system itself is not changing.

Eyes on Earth Episode 135 – Exotic Annual Grasses and Sheep Grazing

Exotic annual grasses, or EAGs, are invasive species. They outcompete native grasses. They are extremely flammable. And they are expanding into higher elevations. Targeted sheep grazing is one way to combat these invasive grasses, manage fire risk, and help restore native sagebrush in western states. The EROS team releases weekly EAG maps during the peak green-up in late April to early June, along with annual phenology maps to show the seasonal timing of the green-up. Dr. Kelly Hopping at Boise State University is using these maps to see whether targeted sheep grazing can help manage EAGs. The maps help researchers work with sheep producers to know when is the best time to move the sheep into those areas so their grazing can do the most good. The sheep then, as a part of the team solving the problem of invasive grasses, get to eat in the field when they might not otherwise have grazing available. Learn more in this episode of Eyes on Earth.

Eyes on Earth Episode 44 – Landsat Water Atlas

Dr. Alan Belward has spent a lot of time thinking about the planet’s surface water. The former Landsat Science Team member uses satellite data to track changes to lakes, rivers, and streams, and recently published a book that uses Landsat data to tell some of those stories. In this episode of Eyes on Earth, we hear about some of the surprising things Belward and his team learned about how surface water has changed since the early 1980s and about the value and importance of remote sensing to the study of this critical resource.

Eyes on Earth Episode 89 - EROS Workers and Weather

When the snow gets deep and the wind blows, it can be challenging for workers to travel to the USGS EROS Center, located several miles north of Sioux Falls, SD, on what used to be farmland. Most can telecommute these days, but in this episode of Eyes on Earth, we discover how essential employees ensure there is in-person continuous monitoring of Landsat ground station operations during winter weather—sometimes even requiring an overnight stay.

Eyes on Earth Episode 81 - Tour of the EROS Radome

The Landsat satellites have been collecting Earth imagery for more than 50 years. A key piece of equipment that moves the data from the spacecraft to the archive so researchers can use it is the antenna at the EROS Center. The antenna and its radome have a fascinating history of their own that adds to the overall Landsat story. In this episode of Eyes on Earth, we go on location to learn about how the antenna works and how the ground station engineers at EROS make it possible to study land change with Landsat
