    • EM300 Multibeam Sonar Data collected from May 7 to May 22 from NOAA Ship Hi'ialakai cruise HA-17-01 to the Commonwealth of Northern Mariana Islands (CNMI) and Guam in 2017

    Metadata Updated: March 16, 2024

    Multibeam data were collected using a Simrad EM300 30-kHz sonar aboard NOAA Ship Hi'ialakai, a 68-m (218') NOAA research vessel, from May 7 to May 22, 2017 during cruise HA-17-01. Multibeam data were acquired at Guam and Aguijan in the Marianas. The multibeam data were collected using Kongsberg SIS software in the *.all format and processed using SABER and QPS Qimera editing software. Surface sound velocity values were supplied by Seabird SBE-45 MicroTSG and a SBE-38, and motion corrections from a TSS/Applanix POS MV (Model 320 Version 5) vertical reference were applied to the data in real time. WGS84 datum. The vessel is equipped with a sound velocity profiler and casts were acquired during mapping operations. However, because insufficient sound velocity profile data were collected at depth during surveys around Guam, sound velocity profile data were applied from an earlier survey (HI-07-02). At Aguijan, suitable sound velocity data were acquired; however, the surveyed areas were previously mapped and therefore the data for Aguijan was not processed. Depths mapped range from ~50 m to 1000 m. These data are not to be used for navigation.
