The primary goal of this study was to create a series of 1-cm resolution 3D models of vent groups found in Tongan waters, specifically on the Northeastern Lau Basin. These models then formed the reference for layered environmental maps at unprecedented resolution that can help define the nature of venting, fluid temperature/chemistry, and animal clusters in these unique environments. The final product was the first ever open-access, virtual model of an entire vent field, not just individual chimneys. This innovative survey approach can spark new strategies of deep ocean floor research and create an immersive tool for public engagement.
