Did you know October 10 is Electronic Records Day? We’re celebrating with a #ThrowbackThursday to this past July, when our Bird Banding Laboratory finished scanning 1.3 million bird banding sheets containing tens of million records collected from the 1960s-2000s. The paper records were loaded into the 365 file boxes seen in the video below and transported to the National Archives. The effort to digitize paper records from the Bird Banding Lab began in 2015, and was completed with the help of the Secondary Transition to Employment Program-USGS Partnership or STEP-UP program. STEP-UP provides 18 to 22-year-old students with differing abilities the skills needed to transition from an academic to a business setting. The students have become an integral part of the data archiving process. Learn more: https://ow.ly/XIlt50TJf2n

We’re accepting applications for Mendenhall Fellowships! Why apply to be a Mendenhall? Hear it from Dr. Lisa Zieman, a USGS Mendenhall Fellow who is currently studying the relationship between tectonics and the formation of critical mineral deposits. “I have really enjoyed collaborating with other USGS scientists and making connections with university and USGS labs within the U.S. and internationally. In addition to leading an independent research project as a Mendenhall fellow, I have had the opportunity to become involved in other interesting projects with my USGS mentors. This fellowship has also allowed me to continue doing field work in scenic places as well as lab work in-house regularly.” Learn more about the Mendenhall Fellowship: https://ow.ly/ml0b50TI54w Apply by November 1! 📸: Dr. Zieman takes notes while conducting fieldwork to study critical minerals.

Get the latest USGS resources on post-Helene landslides, including a map of current landslide observations and an event overview at: https://ow.ly/kf8V50TEGEc FEMA Image: a scientist looks out the window during an aerial reconnaissance flight to get a better understanding of the extent and severity of landslide impacts in the southern Appalachian region.

Get the latest locations of landslides associated with Hurricane Helene at our Landslide Observations Dashboard: https://ow.ly/IFbc50TEEO2 Landslides are an ongoing hazard in the aftermath of Hurricane Helene. USGS and a growing list of state and federal collaborators are at work locating landslides and adding them to the map, drawing on ongoing aerial surveys of the region via fixed-wing aircraft, satellite imagery, and on-the-ground information. The dashboard will be updated as new data come in. The landslide event team does due diligence in attempting to confirm the accuracy of each landslide report but the dashboard is a rapid emergency analysis of the data that’s currently available and provisional only in nature.

Exciting updates from the annual Principals’ Meeting of the Interagency Arctic Research Policy Committee (IARPC), held on September 18 at the Eisenhower Executive Office Building. USGS Director Dave Applegate had the privilege to engage with leaders from NOAA: National Oceanic & Atmospheric Administration, NASA - National Aeronautics and Space Administration, and the Smithsonian Institution during a panel discussion that focused on our collective achievements and established priorities for Arctic research. Together, they emphasized the importance of collaboration in navigating the unique challenges presented by the Arctic environment. Looking ahead, we are embarking on future visioning for the Arctic Research Plan, which will guide our efforts through 2027 and beyond. This is a crucial time to strategize and innovate as we seek to enhance our understanding of Arctic systems and address pressing environmental concerns. USGS continues to strengthen our leadership and commitment to Arctic research and stewardship.

Raise your hand if you currently use or have used supercomputers in the past. 🤚 Did you know they can protect lives, infrastructure, and environmental resources threatened by volcanoes? 🌋 For the USGS, we have 3 high-performance computing systems (i.e. supercomputers) that we use to process large datasets and quickly solve complex physics equations. These incredibly fast supercomputers allow scientists to tap into machine learning, data assimilation, and probabilistic hazard assessments (i.e. more sophisticated approaches) to better evaluate potential hazards like lahars. A lahar is an Indonesian term that describes a hot or cold mixture of water and rock fragments that flows down the slopes of a volcano. A moving lahar looks like a roiling slurry of wet concrete and can travel great distances downstream, threatening communities many miles away from the slopes of the volcano. By knowing how these hazards might play out, we can help keep people safe by having them be better prepared for the “what if?” To learn more about how supercomputers are empowering scientists to better model potential volcanic hazards, please visit: https://ow.ly/HKpJ50Txqfk 📹: Simulation of a landslide & lahar originating from Tahoma Glacier on Mt. Rainier, WA. Colors represent flow depth in meters, ranging from 0 to more than 100 meters (>300 feet). #BePrepared #NationalPreparednessMonth #PreparednessMonth #volcanoes #landslides

Do you study or manage mine lands? We are excited to share a new report that describes how satellite and other aerial imagery can be used to assess and restore mine lands. While remote sensing has been used to study all kinds of things, from carbon storage to wildfire severity, this approach hasn’t been used widely to study mine lands yet. But there’s a lot of potential in this approach for mine lands: it allows researchers and managers to understand how mine lands have changed over large geographic areas and decades-long time scales, for relatively little cost. For example, this series of satellite images shows a coal mine in the Appalachian Mountains of southern West Virginia, first in 1984 when the total disturbed area was relatively small, then in 1998 when the mine had grown westward, and then in 2015, when mining ended, some vegetation recovery was visible from Landsat imagery as light green.

After 132,000+ trips around Earth and 3.3+ million satellite images, the incredible journey of the Landsat 7 satellite comes to a close, making way for the next generation of Landsat satellites. 🛰️🌎 A joint mission between USGS and NASA - National Aeronautics and Space Administration, Landsat 7 was initially designed for a five-year mission but far exceeded expectations, observing our planet for a remarkable 25 years! Its invaluable data has benefited humanity and enhanced our understanding of Earth. “Landsat 7 data have been pivotal in documenting environmental changes such as natural disasters, deforestation, and urban growth over its 25 years,” said Dave Applegate, USGS Director. “Notably capturing significant events like Hurricane Katrina in 2005, the Haiti earthquake in 2010, the Australian bushfires in 2019 - 2020, the dramatic growth of cities worldwide and more through its long-standing mission.” “For more than fifty years now, Landsat satellites have helped us learn more about how Earth systems work, how human activities affect those systems, and how we can make better decisions for the future. Landsat 9, the latest joint effort by NASA and USGS, proudly carries on that remarkable record,” said Bill Nelson, NASA Administrator. While we await the Landsat Next mission, Landsats 8 and 9 continue to carry out the Landsat mission, working together to image the entire Earth’s surface every 8 days. This provides a continuous record of Earth imagery dating back to 1972.
