We found no clear evidence of any present discharge at either of the SeaBeam anomalies. Hydrothermal activity here may be decreasing more slowly than at CoAxial. Rise height has not changed much since Feb. Sounds like a good place for a seafloor observatory. That's it for now. Greatest plume so far are over and around Sonne vent field.
Optical anomalies are greater than ever previously measured, but temperature anomalies small.
Visual inspection of filters suggests most plumes not composed of mineral precipitates, likely bacterial. H2S scent remarkably strong from bottles. Plume height over Sonne at 200m maximum with many individual layers. Particle anomalies at Sonne more intense than Wecoma response cruise immediately after event. After 6 months since event, hydrothermal discharge still robust.
