    • Depth soundings from a single beam echo sounder collected around the nearshore areas of the U.S. Pacific Islands since March 2012

    Metadata Updated: October 19, 2024

    This dataset contains singlebeam bathymetry data collected from NOAA small boats by the NOAA Coral Reef Ecosystem Program since March 2, 2012 in the U.S. Pacific Islands Region, including the Hawaiian and Mariana Archipelagos, American Samoa, and the Pacific Remote Island Areas. Data was acquired with a transom-mounted AirMar P66 (prior to 2016) or an AirMar TM258 1 KW (2016 to present) single beam echosounder. The 2012-2015 data was processed using a custom NMEA python script, and the current data (since 2016) is processed using GPS Utility. Error analysis on the data from 2012-2017 was performed by comparing the singlebeam data to existing multibeam data where the two datasets overlapped.

    Lineage Data was acquired with a transom-mounted AirMar P66 (prior to 2016) or an AirMar TM258 1 KW (2016 to present) single beam echosounder. The 2012-2015 data was processed using a custom NMEA parsing script written by Jeff Anderson. The current data (since 2016) is converted from Furono GPS track points (PNT/TRK files) to comma-separated TXT using GPS Utility. The exported TXT files are parsed to separate the track header content from the data. Redundant data, if applicable, are removed (this occurs if the instrument is not cleared between data downloads). Values in the coordinates fields are edited to convert the alpha characters (N, S, E, W) to numeric representations (negative is applied for S and W). Data are then evaluated in GIS to set the descriptive locations (REGION and ISLAND). Once manual processing is complete, the data are migrated to the Oracle database. Data that are distributed are filtered to remove NULL depth and speed values and records in which TRACK = 1, and depth values are converted to negative.
