Notes on Vent Field Description:
Lupton et al. (2011): "Of the seven bottles sampled, only a single bottle had a clear excess in 3He, and this was a fairly weak signal about 3% above the V07B-12 background in δ3He units (Figure 11). However, the along-axis tow over Sisifo (T07B-13) did detect a weak particle anomaly over the southeastern section of the seamount, where no discrete samples were collected (Figure 11a). Thus it is possible that some hydrothermal activity may have gone undetected in this portion of the seamount."
