Summary:

- La Jolla scientist, Celeste Labedz, is using seismic data to investigate a mysterious signal that has been detected around the world, known as the "Upsweep" signal.
- Labedz is analyzing seismic data from various sources, including ocean-bottom sensors and land-based seismic stations, to try to pinpoint the source and nature of the Upsweep signal, which has been detected for decades but remains a mystery.
- The study of this signal could provide valuable insights into Earth's structure and processes, as well as potentially leading to the discovery of new natural phenomena or even human-made sources of the signal.
