Such sites are generally surveyed using remotely operated vehicles, with their camera system providing only limited field of view, limiting productivity compared to on-land studies. We briefly report advances of interlinked projects to improve on this situation: (a) The Schmidt Ocean Institute funded cruise FK160320 visited the Niua South volcanic field in Tongan waters, photogrammetrically mapping an area 500m x 500m x 80m at \u201cindustrial\u201d scales. We comment on the challenges of photogrammetrically processing and visualizing a data set of 220.000 images resulting in billions of 3D points, including the lessons learned regarding survey design. The consequence of this expedition was the LIGHTHOUSE technology validation project, in which a highly integrated suite of acoustic sensors, cameras and laser scanners are fused to create a real-time 360\u00b0 model of the seafloor surroundings. This project sported the development of the world\u2019s first commercially available native underwater, deep-ocean capable survey lens in cooperation with Carl Zeiss Jena. Lastly, we will touch on our efforts to visualize the seafloor in the spatially immersive <a href=\"https:\/\/www.geomar.de\/en\/arena\" data-type=\"URL\" data-id=\"https:\/\/www.geomar.de\/en\/arena\" target=\"_blank\" rel=\"noreferrer noopener\">ARENA2 visualization dome<\/a> at GEOMAR, facilitating quantitative visualization and virtual field work.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>On August 25th, 13:00 UTC, CoSV hosted the webinar entitled &#8220;Virtual Fieldwork on the Seafloor with the help of Robotics and 3D Visualization\u201d.
