| Research Abstract |
In this research program, we observed a concrete and detailed knowledge on wave-resistant structure of reefs from geomorphology and sedimentology. The firstly, we attempts to observe three-dimensional topography of outer reef slope such as spurs and grooves using high-resolution multibeam bathymetric sonar which was introduced by this research grant. This is the first 3D visualization of complex outer reef slope topography in the Ryukyu Islands. We also analyze the drilling cores that we drilled in the Ryukyu Islands and Maldives. The development of submarine cement is distributed significantly at the upper reef edges and contributed to form the rigid reef structure.
