Vent assemblage and substratum of the Eiffel Tower hydrothermal edifice from 1994 to 2008
The Eiffel Tower hydrothermal edifice is a large structure of ~450 m2 located 1700 m deep at the Lucky Strike hydrothermal vent field. Since its discovery in 1992, the edifice has been repeatedly visited at pluriannuel time scales. Photomosaics of different sides of the edifice were assembled based on videosequences acquired from 1994 to 2008. Surface of substrata and vent megafaunal assemblages were delimited and their total cover were extracted to investigate their dynamics over time.
