Any island which rises from the deep-sea floor rather than from shallow continental shelves.

Hence an oceanic island at first sight seems to have been highly favourable for the production of new species.
The volcanic nature of these oceanic islands is evidently an extension of that law, and the effect of those same causes, whether chemical or mechanical, from which it results that a vast majority of the volcanoes now in action stand either near sea-coasts or as islands in the midst of the sea.
The scientists have now #page-1:published their results,# under the title "Doubling diversity: a cautionary tale of previously unsuspected mammalian diversity on a tropical oceanic island.

Sipadan Island, the only oceanic island in Malaysia, forming a beautiful atoll secluding and protecting its sea animals and fish.
The authors incorporate immigration, extinction, speciation, and oceanic island senescence into one model that is testable by comparing biodiversity indices across an archipelago.
Sipadan is the only oceanic island in Malaysia; it is not attached to the continental shelf and stands on a limestone and coral stalk, rising 600 metres from the bed of the Celebes Sea.
Ophiolitic rocks and melanges occur along western margins of the Indo Pakistan block in Lasbela-Khuzdar, Muslim Bagh-Zhob and Waziristan while deep seated thrusts known as MKT and MBT are the suture zones between Eurasian Continental Plate, Kohistan Oceanic Island arc and Indo Pakistan Continental Plate.
Other topics of the 21 papers include the formation of Martian river valleys by impacts, oceanic island basalts and mantle plumes, frictional melting processes in planetary materials, spatial patterns in isotopic biogeochemistry, and glacial earthquakes in Greenland and Antarctica.
Many anecdotal accounts exist of large crocodiles being sighted far out to sea, but this is the first study to show - using underwater acoustic tags and satellite tracking - that estuarine crocodiles ride surface currents during long-distance travel, which would enable them to voyage from one oceanic island and another.
Thus, oceanic island basalts (OIBs) provide important chemical evidence regarding mantle composition, magma formation processes and magma evolution.
A third to a half of all oceanic island species were likely to be extinct or on the brink of extinction by 2100.
