The outer coastline of Fongafale Island faces the Pacific Ocean.  There’s a reef for a few metres, then a huge drop off to the deep ocean.  Somewhere on Fonagafale Island (I didn’t find the location) is the location of geological experiments carried out in the 1890s, drilling down into the bedrock, which successfully proved Charles Darwin’s theory that atolls were formed on subsiding volcanic rocks which carried dead coral down to greater depths as the volcanic foundation sank, but meanwhile new coral was forming on the surface to keep pace.
