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

Description

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.
