    • CRED Simrad em300 multibeam backscatter data of Howland Island, Pacific Remote Island Areas, Central Pacific in GeoTIFF format

    Metadata Updated: March 22, 2025

    Multibeam backscatter imagery extracted from gridded bathymetry of the shelf and slope environments of Howland Atoll, Pacific Island Areas, Central Pacific. These data provide coverage between 8 and 3800 meters. The backscatter dataset includes data collected using Simrad EM300 and Reson 8101 multibeam sonars. The sonars frequencies are 30 kHz and 240 kHz respectively and the backscatter data from each sonar are processed and gridded separately. These metadata are for the 5 m grid cell size Simrad em300 multibeam backscatter data only.
