Cocos Island off Costa Rica, the Galapagos Islands, Socorro in Mexico, Madivaru Corner in the Maldives, and the coast of Malaysian Borneo which
features oceanic islands and deep water atolls such as Layang Layang, are among the best dive locations for sightings.
Greater understanding of the ocean floor and the discoveries of
features like mid-
oceanic ridges, geomagnetic anomalies parallel to the mid-
oceanic ridges, and the association of
island arcs and
oceanic trenches occurring together and near the continental margins, suggested convection might indeed be at work.
