A group of islands in Melanesia constituting a French overseas territory. The group includes New Caledonia (the main island), Ile des Pins, Loyalty Island, and several other islet groups. The capital is Noumea. It was discovered by Captain Cook in 1774 and visited by various navigators, explorers, and traders from 1792 to 1840. Occupied by the French in 1853, it was set up as a penal colony 1864-94. In 1946 it was made a French overseas territory. It was named by Captain Cook with the 5th and 6th century A.D. Latin name for Scotland, Caledonia. (From Webster's New Geographical Dictionary, 1988, p830 & Room, Brewer's Dictionary of Names, 1992, p375)

The hydrous Ca–Al silicates lawsonite and epidote group minerals (EGMs) are key phases in subduction-zone H2O and element cycling. In high-pressure–low-temperature metamorphic rocks, Fe in both minerals is typically assumed to be entirely Fe3+, which substitutes for Al in octahedral sites as a major component in most EGMs and as a minor component i...
Most scleractinian corals are under threat from global warming, yet some exhibit remarkable resistance to heat stress. Coral thermal tolerance depends on both the intrinsic properties of the cnidarian host and the physiology of their symbiotic algae (Symbiodiniaceae). Some corals adapt to heat stress by altering their Symbiodiniaceae communities, b...
In France, the notion of “deep‐sea/deep‐seabed” (“grands fonds marins”) has emerged fairly recently in public policy discourse, and in particular in the wake of the 2009 Grenelle de la Mer, which marked the French government’s desire for an integrated maritime policy. The Grenelle de la Mer is a public process of reflection and negotiation between...
