Short summary
This study focuses on foraminiferal distribution in the Luck Strike vent field, one of the most studied hydrothermal vents. Our results demonstrate that diversity increased where vent-derived particles are mixed with pelagic sedimentation, as it's the case in seafloor massive sulfide targeted for deep-sea mining by the industry. This study also revealed the impact of microbial biofilms on carbon budget though carbonate dissolution.
