An Update on the Taywood West Surface Mine

After our discovery of what appeared to be a significant amount of mining taking place outside the permit boundaries provided by the West Virginia Department of Environmental Protection (WVDEP), we did a little digging to try and get a better idea of what exactly happened. With the help of colleagues at Appalachian Voices, we found […]

Planet Imagery sheds light on Mine Expansions outside of Permit Boundaries

We were recently reviewing imagery of mine sites which experienced growth in 2017. We overlaid the mine permit boundaries that show where the government has legally granted companies permission to mine. We used our Landsat-based surface mining data to identify a set of candidate sites to examine more closely with higher-resolution Planet imagery through Planet’s […]

Our Shrinking National Monuments

The President announced sizeable reductions of several National Monuments earlier this week.  To help people see and understand the significance of this action, we produced an interactive map showing two of the most highly impacted Monuments, Bears Ears and Grand Staircase – Escalante, both in Utah.  Users of the map can zoom in and explore the […]

Update on Our Efforts to Map Surface Mining in Appalachia

Some time has passed since we’ve written about our work mapping surface mining in central Appalachia, but rest assured, we’re still actively monitoring this devastating practice. Our mining work to date has focused on mapping the locations of these operations. Researchers, some of whom are using our data, are beginning to draw troubling connections between […]

Harvey’s Environmental Impact, a Look at Flooded Petrochemical Sites

Since Hurricane Harvey made landfall last month, we continued to analyze satellite imagery along the middle of the Texas Gulf Coast for environmental impacts. The first in a series of catastrophic storms, Harvey struck the heart of the U.S. petrochemical industry, leading to widespread flooding of oil and gas infrastructure, toxic chemical spills and adverse short […]

Summer Research Focus

It’s an exciting time around the office. We finalized our summer research program and added a couple of new faces—interns Brian Wong from Duke University and Flynn Robinson from West Virginia University—to help us expand our skill set and cover more ground. Brian is helping us improve our mountaintop removal (MTR) mining work. We’ve already […]
