[1] HAWAII MR1 is short for HIGP (Hawaiʻi Institute of Geophysics and Planetology) Acoustic Wide Angle Imaging Instrument, Mapping Researcher 1.
[2] It has been used in the discovery of several objects and locations of note, examples being the USS Yorktown[3] and the HMRG Deep.
Because it is not hull-mounted, this data collection system has the ability to withstand rough conditions.
[5] The HAWAII MR1 was chosen to be used on an expedition headed by Robert Ballard, the person who discovered the RMS Titanic.
"[3] Bruce Appelgate, at the time director of field operations at HMRG, noted that they were fortunate in finding the ship, as it was at the very edge of the MR1's resolution.
