Following the intriguing exploration of scorching vent and chilly seep ecosystems, the rediscovery of cold-water coral ecosystems with high-technology instrumentation is at present one other sizzling subject in multidisciplinary marine study. Conventionally, coral reefs are considered as limited to hot and well-illuminated tropical seas, now not linked to chilly and darkish waters of upper latitudes. even if, ongoing clinical missions have make clear the worldwide importance of this neglected environment. Cold-water coral ecosystems are fascinated with the formation of enormous seabed constructions similar to reefs and big carbonate mounds, and so they characterize unexploited paleo-environmental files of earth historical past. Like their tropical cousins, cold-water coral ecosystems harbour wealthy species range. regardless of the good water depths, advertisement pursuits overlap a growing number of with the coral occurrences. Human actions already impinge at once on cold-water coral reefs inflicting critical harm to this susceptible environment. during this quantity, the present key associations occupied with cold-water coral examine have contributed sixty two state of the art articles from geology and oceanography to biology and conservation.
