Though a second exploratory ROV dive on Site 2A provided the Team with a better understanding of the complex geology on the seafloor, we have yet to locate the source of the intense hydrothermal plume in the water column. We conducted a slower and higher resolution tow-yo overnight in hopes of better localizing the plume source and improve our understanding of mid-water anomalies to the east. Immediately after the CTD was back on deck, Senior Survey Tech Colleen Peters sent the data to Sharon Walker in Seattle. We owe Sharon a big thanks for working well into the early morning to process the data in time to select today's ROV dive target.
