Figure 2: Characteristics of the VDVF water column.
From: Hydrothermal vent fields and chemosynthetic biota on the world's deepest seafloor spreading centre
(a) Profiles of temperature and salinity above the MCSC from a CTD instrument, showing a deep isothermal water column; (b) Profiles of LSS and redox potential (Eh) signals indicating the hydrothermal plume above the VDVF (c) Autosub6000 survey of Eh anomalies at 60-m altitude above the VDVF. Eh values in these diagrams are the raw values of the platinum (Pt) electrode voltage against the silver–silver chloride (AgCl) reference electrode in a saturated potassium chloride (KCl) solution.
