Fig. 4: La Scala Vent Field.
From: Active hydrothermal vents in the Woodlark Basin may act as dispersing centres for hydrothermal fauna
a, b Chimney cluster (‘Pandora Site’), SE of the vent field at 3380 m depth characterized by a few black smokers and predominant weakly diffusive vents. This site is surrounded by cirripeds to the West, North and East. c, d Second site (‘Corto Site’) located on the flank of a cliff controlled by a N55-60 fault. The South area at 3360 m depth is the most active of the hydrothermal field. e Massive prismatic lava. f Highly altered basalts due to past high temperature hydrothermal circulation. g Large colonies of Vulcanolepas sp. colonizing inactive chimneys. h A patch of Alviniconcha endosymbiotic gastropods surrounded by Ifremeria nautilei and Vulcanolepas sp.
