This Halloween season, we're remembering the federal datasets that have met an untimely end — the ones that were terminated or removed since January 20, 2025. Help us memorialize these Dearly Departed Datasets so we can all understand what was lost and why they matter. 🌕 Hosted by: EssentialData.US, Federation of American Scientists (FAS), Public Environmental Data Partners (PEDP), and The Impact Project 🐈‍⬛ Deadline: Wednesday, October 29, 2025, at 11:59 pm ET 🕯️ Submission Note: One submission per dataset, please.
