NCCOS Mapping: Bathymetric Lidar Waveform Metrics for Saipan, The Commonwealth of the Northern Mariana Islands (CNMI), 2019-07-11 to 2019-07-31 (NCEI Accession 0294340)
This data package contains bathymetric light detection and ranging (lidar) Hawkeye-4X waveforms metrics (LWFM) for 0 to 50 meter depths around the island of Saipan, Commonwealth of the Northern Mariana Islands (CNMI). Bathymetric lidar waveforms depict the amount of laser light returned from the seafloor recorded during each laser pulse. Typically, only the leading edge of the seafloor return is used to calculate bottom depth. However, the shape of the seafloor return also contains novel information about the physical structure and biological cover on the seafloor (Collin et al. 2011, Wilson et al. 2019). To extract this information, the National Oceanic and Atmospheric Administration (NOAA) National Centers for Coastal Ocean Science (NCCOS) partnered with Oregon State University (OSU), NOAA Office for Coastal Management (OCM), Woolpert and Hexagon Leica to develop software to export, process, normalize and rasterize 16 LWFM describing the shape of the seafloor return (Jung et al. 2024; Collin et al. 2011; Parrish et al. 2014; Kashani et al. 2015; Kogut et al. 2022). The resulting LWFM rasters were used to predict the distribution of key coral reef taxa and habitats west of Saipan (Costa et al. 2024). This effort marks one of the few studies that have used LWFM to predict tropical coral reef habitats to date. These processing workflows and associated software will also make LWFM creation easier and more routine for future Hawkeye-4X lidar collections by NOAA and its partners. This project was funded by NOAA’s Coral Reef Conservation Program (CRCP), and leverages significant investments made by NOAA NCCOS, NOAA National Geodetic Survey, NOAA Office for Coastal Management, and the U.S. Geological Survey in the region.

Purpose | The purpose of this effort was to develop standardized processes and software to extract, normalize and rasterize bathymetric lidar waveform metrics (LWFM). LWFM have shown promise to enhance NOAA’s ability to predict and map the location of benthic habitats (Collin et al. 2011), including coral reefs (Wilson et al. 2019). The study site for this research was 0 to 50 meter depths around the island of Saipan in the Commonwealth of the Northern Mariana Islands (CNMI). This area was selected because its shallow-water coral reefs include ecologically and economically valuable coral taxa, which have been stressed by multiple typhoons and warm-water bleaching events over the last decade. In response to these disasters, NOAA and USGS contracted Woolpert to acquire Hawkeye-4X topographic-bathymetric lidar data around coastal areas of CNMI, including Saipan (Woolpert 2019; NOAA and USGS 2019). These data were used to understand impacts from these disasters in the region, including the damage done to the surrounding coral reefs. The LWFM were used by NOAA NCCOS to create updated coral reef maps for local resource managers on Saipan (Costa et al. 2024). |
