Notes on Vent Field Description: 
located on Segment 16, CIR; Tamaki (2010): "The black smoker fluids in the Dodo field exhibit unusually high concentrations of H2 in spite of the slightly brine-enriched feature of the fluids."; Miyazaki et al. (2010): "10 to 15 active chimneys"; Nakamura et al. (2012): "The most vigorous black smoker discharges were observed at the Tsukushi-2 chimney site, at which the highest temperature of hydrothermal fluid (356 C) was sampled."; Kitazato et al. (2014) mentioned the cruise led by M. Nishizawa (JAMSTEC) in 2013 had one dive with Shinkai 6500 in the DODO field: "We found no signs of presently active hydrothermal fluid discharge in the DODO field, indicating that hydrothermal activity in the DODO field had stopped during the period from 2009 to 2012."
Notes Relevant to Biology: 
Tamaki (2010): "Chemosynthetic faunal communities in the Dodo field are emaciated in size and composition."; Miyazaki et al. (2010): "We observed only crabs and shrimps but we did not found shells." Nakamura et al. (2012): "As far as we observed, no Alviniconcha gastropods, ‘scaly-foot’ gastropods or mussels were present".
Year and How Discovered (if active, visual confirmation is listed first): 
2009 submersible Shinkai 6500; 2006 plume only
