    3D surface analysis of coral microatolls by Gautam, Rohan

    Published 2022
    “…Studying microatolls is typically done by slabbing, an invasive process where a radial slice is obtained in order to study its annual growth bands. This is an invasive method. In this paper, we aim to lay a foundation for non-invasive analysis of coral properties by studying the 3d surface of the corals collected through LIDAR and photogrammetry techniques. …”
