Further important discoveries in submarine volcanic settings have
recently been made using other deep-water AUVs. For example,
Marcon et al. (2013) used the MARUM Seal 5000 AUV to map the
Menez Gwen hydrothermal vents, which, at 800 m WD, are the
shallowest known vents on theMAR that host chemosynthetic communities.
Kumagai et al. (2010) used the JAMSTEC Urashima AUV to map
the Iheya–North hydrothermal vent field off Okinawa. In addition to high-resolution bathymetric and backscatter mapping of the seafloor,
novel application of AUV SSS imagery enabled detection of active hydrothermal
plumes in the water column with upwelling speeds of ~1 m/s.
The presence of active plumes was confirmed by CTD and pH sensor
data derived fromthe AUV.
