Notes on Vent Field Description: 
oceanic rift (early opening); note: Tadjoura Rift is western extension of Aden Ridge; R/V Hakuho-maru CTD and GAMOS; Gamo et al. (2001): "We searched for hydrothermal plumes along spreading axes in the Gulf of Aden, between 45\deg36'E and 52\deg42'E, using a CTD multi-water sampling system, mapping water column distributions of light transmission and chemical tracers (Mn, Fe, CH4 etc.) in December 2000 and January 2001."; Tamaki et al. (2001): "In the easternmost part of Tadjoura Rift at 45 deg 35 min E we observed shallow peaked twin mountains (Aden New Century Mountains) along the central axis of the rift with the summit depth of 500m. "
