Louisa Reef, Brunei

We identified a reef 224 km north by northwest of the southern coastal border between Brunei and Malaysia. It is 2.0 km long, and is shaped like a triangle with the 90 degree angle in the northwest corner. We see a tiny bit of reclamation (we estimate 40 meters) in the southwest corner. Location: Lat: 6.3307787, Lng: 113.2431233, Copernicus Browser, Sentinel-2, L2A, True Color satellite imagery as of 7/31/2024.

This is an underwater atoll without reef channels.
