Fly-through from the south toward the north along the Lau basin. The blue squares signify proposed remotely operated vehicle dive sites during the SRoF’12 expedition. 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, much of which was compiled by Fernando Martinez, University of Hawaii. The satellite altimetry data are courtesy of Smith and Sandwell, 1997. Seafloor data are 2 times vertically exaggerated. Fly-through created by Susan Merle OSU / NOAA Vents Program.

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. Fly-through created by Susan Merle OSU / NOAA Vents Program.

Slideshow

3D images slideshow of the Submarine Ring of Fire 2012: Northeast Lau Basin proposed remotely operated vehicle dive sites. All images are two times vertically exaggerated. Most of the bathymetry data is higher resolution multibeam (EM300 and EM122), 35-meter grid-cell size.
