Excerpt from Studies in Coral ReefsAll atoll lagoons have some shoals, and these are more numerous near their encircling reefs. Where a small horn of a lagoon is nearly enclosed by reef, there may be a shallowing of its waters and many closely set shoals. This is often more noticeable still, as in the south horn of Funafuti, where the greater part of the reef is crowned with land. In such places shoals may be packed between with detritus and added to the encircling reef. In the central sixty or seventy square miles of Funafuti lagoon there are twenty shoals, nearly all of which reach the surface, many being mere peaks, their total area not more than two per cent of the whole. Nearly all these shoals in lagoons arise perpendicularly in their upper few fathoms, falling steeply below to the bottom plateau of the lagoon. There may be some screes, broken-off material from the same, but there is little or no indication of any proba bility of the upgrowth and outgrowth of such shoals at deep levels by living organisms.About the PublisherForgotten Books publishes hundreds of thousands of rare and classic books.
