Description:
Abstract:
EM1002 and EM120 multibeam Data were collected in October/November 2002 aboard R/V Kilo Moana between Kauai Island and Lisianski Island in the Northwestern Hawaiian Islands (NWHI). Multibeam data were collected using Simrad Neptune software, converted to the Generic Sensor Format, and processed using SABER editing software. Sound velocity corrections from CTD's and motion corrections from a POS-MV vertical reference were applied to the data in real time. No tidal correctors were applied in real-time or in post-processing. The EM1002 has heave artifacts (~0.6m) in shallow bank-top data.

Horizontal accuracy is 20m (no differential GPS correctors applied), vertical accuracy is depth dependent (~1% of water depth), WGS84 datum. These data are not to be used for navigation. Depths mapped range from 30-5200 meters below sea level.

Purpose:
The data were collected to provide information on the 25, 50, and 100 fm contours in the NWHI, which are important for establishing management boundaries for the NWHI Coral Reef Ecosystem Reserve. The data are being used to provide bathymetric and backscatter data for previously unmapped areas. The data support ecosystem management requirements for benthic habitat mapping and location of Essential Fish Habitat. The data are also used to study the geologic features of the area.
Supplemental_Information:
Data were collected aboard the R/V Kilo Moana, a 57 m (186') oceanographic research vessel operated by the University of Hawaii, School of Ocean and Earth Science and Technology undera a charter agreement with the Office of Naval Research. The R/V Kilo Moana survey sensors include a 12 kHz Simrad EM120 sonar and a 95 kHz Simrad EM1002 sonar, used to acquire bathymetry and acoustic backscatter imager, a TSS/Applanix POS/MV Model 320, which measures time, position, velocity, attitude and heading, and expendable bathymetry thermographs (XBT) to acquire sound velocity profiles.
