2007 EM300 and EM3002D Multibeam Sonar Data from Cruise Hi'ialakai HI0703 - Commonwealth of the Northern Mariana Islands

Metadata Updated: February 27, 2019

EM300 and EM3002D multibeam Data were collected from May 25-June 9, 2007, aboard NOAA Ship Hi'ialakai at Saipan Island, Tinian Island, Sarigan Island, Zealandia Bank, Anatahan Island, Guguan Island, Alamagan Island, Agrihan Island, Asuncion Island, Maug Islands, Supply Reef, Uracus Island, and Pagan Island during cruise HI0703. These multibeam data were collected using SAIC ISS-2000 software in the Generic Sensor Format and processed using SABER editing software. Surface sound velocity values were supplied by a Seabird SBE-45 MicroTSG and a SBE-38 remote temperature probe. Sound velocity corrections from a Seabird 911 CTD sensor and motion corrections from a POS-MV vertical reference were applied to the data in real time. Predicted tides were applied to the data in real time. Horizontal accuracy is 20 m (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 ~20-3000 m. Concurrent mapping at Saipan Island, Tinian Island, Sarigan Island, Zealandia Bank, Anatahan Island, Guguan Island, Alamagan Island, Agrihan Island, Asuncion Island, Maug Islands, Supply Reef, Uracus Island, and Pagan Island was done by the R/V AHI in water depths ranging from ~10-350 m with The data set being AHI0703; (metadata for AHI0703 are submitted separately.)
