Mulibeam data were collected aboard the NOAA Ship Hi'ialakai, a 218' United States National
Oceanographic and Atmospheric Administration research ship. The NOAA Ship Hiialakai'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.
Specific equipment configurations are documented in cruise metadata from the following cruises:
