Noroit Seamount is a seamount in the Caribbean Sea, in the Anegada Passage.[1] It is also spelled Noroît Seamount[2][3] after the French survey and research vessel RV Le Noroît (IMO number: 7035717) which was operated by IFREMER.[4][5][6] It is also known as Noroit Knoll.[7][8] Several research projects are conducted in vicinity of Noroit Seamount.[9][10]

Geology[]

The seamount is a (relatively young) inactive submarine volcano, located on the boundary between the North American Plate and the Caribbean Plate.[2]

Flora and fauna[]

Noroît Seamount's marine habitats[11] are well researched.[3] Investigations by the research vessel EV Nautilus in 2014 found a variety of stony corals (scleractinians), octocorals, and sponges.[12] Corals created habitat for brittle stars, squat lobsters[12] and sea snails.[2] In the sea depth there are variety of fish — Acanthonus armatus,[13] Bathypterois phenax,[14] Bembrops,[15] Conger esculentus,[16] Coryphaenoides,[17][18] Hexanchus griseus,[19] Lepidion,[20] Luciobrotula corethromycter,[21] and Polymixia lowei.[22]
