    • CRED 2005 Reson 8101 Backscatter imagery of the western and central banktop and bank edge environments at French Frigate Shoals, Hawaii, USA

    Metadata Updated: March 22, 2025

    Backscatter imagery extracted from gridded bathymetry of the western and central banktop and bank edge environments at French Frigate Shoals, Northwestern Hawaiian Islands, USA. These data provide almost complete coverage between 20 and 100 meters. The backscatter dataset includes Simrad EM3002d and Reson 8101 data. The sonars frequencies are 300 kHz and 240 kHz respectively and are processed and gridded separately. Because of the similar sonar frequencies the data can be mosaicked nearly seamlessly using GIS software. This metadata is for the Reson 8101 backscatter data only.
