Notes on Vent Field Description:
Chen, Y.J. and Li, J. (2012): "Evidence for 5 new hydrothermal vent fields was collected at South Mid-Atlantic Ridge"; Devey (2014): "In segment 7... the tow-yo track crossed directly over the newly discovered Merian vent field... horizontal plume extent of ~1.5 km", "Next to one such high at 26 01'S 13 51'W the AUV imaged a series of hydrothermal chimneys and mounds (the ‘Merian Vent Field’). The tallest of these chimneys is around 18 m", AUV Abyss dive 128; In addition, Schmid et al. (2019) report elevated d3He on this ridge segment at 26.2 S;
Year and How Discovered (if active, visual confirmation is listed first):
2012 R/V Dayang Yihao; 2013 AUV Abyss plume and side-scan data
