Multibeam data were collected in 2007 aboard the NOAA Ship Hi'ialakai, a 218' United States National Oceanographic and Atmospheric Administration research ship. The NOAA Ship Hi'ialakai's survey sensors include a 30 kHz Simrad EM300 sonar and a 300 kHz Simrad EM3002d sonar, which provide bathymetry and imagery data, a TSS/Applanix POS/MV Model 320, which measures position, velocity, attitude and heading, and a Seabird SBE 9/11 plus CTD used to measure sound velocity profiles.
Multibeam data were also collected aboard the NOAA Ship Oscar Elton Sette in 2010, a 224' (68 m) United States National Oceanographic and Atmospheric Administration research ship. The NOAA Ship Sette's survey sensors included a 240-kHz pole-mounted Reson 8101ER sonar, which provides bathymetry and imagery data, a TSS/Applanix POS/MV Model 320, which measures position,velocity, attitude and heading, and a Seabird SBE19 CTD used to measure sound velocity profiles.
