Notes on Vent Field Description:
Tamura et al. (2013): "HPD1533 explored the 2010 crater to search for hydrothermal activity and to image and sample the northern crater wall (404 - 238 mbsl). ... No hydrothermal venting was observed in the crater, except weak shimmering water at the top of the crater wall."; Embley et al. (2014): "on the crater’s rim, an extensive white filamentous microbial mat covered boulders and outcrops... probably sustained by a diffuse (barely discernible on the video) hydrothermal flow. There were no observations of vent-endemic macrofauna communities and no indicators of active high-temperature venting."
Year and How Discovered (if active, visual confirmation is listed first):
