Interactive Map

Explore global distribution in a larger, map-first view.

This page is designed for interaction rather than summary alone. Filter the release by year or region, switch map scope, and open the map in fullscreen for easier browsing. You can inspect both conservative country-level coverage and sample-level coordinates when BioSample latitude and longitude are available.
