Fly-through from the north to the south along the Northeast Lau basin. The blue squares signify proposed remotely operated vehicle dive sites during the SRoF’12 expedition. This flight starts at the Tonga trench, passes over the North Matas, West and East Mata, Niua, and ends at Volcano O. Colors vary from cool (blues) to warm (red/pink), representing deep and shallow respectively. Islands are black. Satellite altimetry data (coarser bottom layer) is overlaid with higher resolution multibeam bathymetry data collected on recent expeditions to the area. The satellite altimetry data are courtesy of Smith and Sandwell, 1997. Seafloor data are 2 times vertically exaggerated.
