Notes: DSAG/MBG-B = Deep-Sea Archaeal Group, synonymous with Marine Benthic Group B (Vetriani et al., 1999) and Deep-Sea Hydrothermal Vent Crenarchaeotic Group (Takai and Horikoshi, 1999), MG-I = Marine Group I (DeLong, 1992, 1998), MBG-A = Marine Benthic Group A (Vetriani et al., 1999), MBG-D = Marine Benthic Group D (Vetriani et al., 1999), MCG = Miscellaneous Crenarchaeotal Group (Takai et al., 2001), SAGMEG = South African Goldmine Euryarchaeotal Groups 1 and 2 (Takai et al., 2001), TMEG = Terrestrial Miscellaneous Euryarchaeotal Group (Takai et al., 2001), UC-IIb = Uncultured Chimney Group II (Schrenk et al., 2003). * = average of all depths. † = alternate layers of pelagic clay and volcanic ash, ‡ = alternate sediment and sapropel layers; see supplementary information in Coolen et al. (2002).
