Manila Bay shelters almost 2,000 km² of water behind the mountains of the
Bataan Peninsula. Guarding its narrow mouth sits Corregidor, "the Rock",
the tadpole-shaped fortress island where the last defence of the Philippines was fought in
1942. On the eastern shore sprawls Metro Manila, and to the north the
Pampanga delta dissolves into a lacework of fishponds and mangrove channels.

Dive below the surface. Orbit the camera down through the water. No open
bathymetric tile service covers the bay, so the underwater relief is modeled from
distance-to-shore, scaled toward the ~60 m depths off the bay's mouth. The real bay
averages a shallow ~17 m, one reason it makes such a fine anchorage.
