    • Depth soundings from a single beam echo sounder collected around the nearshore areas of Timor-Leste in 2012 and 2013

    Metadata Updated: December 13, 2025

    This dataset contains singlebeam bathymetry data acquired during small-boat surveys conducted from October 20-26, 2012 and June 4-27, 2013 in Timor-Leste by the NOAA Coral Reef Ecosystem Program (CREP). Data was acquired with a HydroLite-TM Echosounder Kit by Seafloor Systems, a small boat Hydro Survey System using Ohmex SonarMite echosounder and Trimble ProXT receiver. The singlebeam bathymetry was used to ground-truth bathymetry derived from WorldView-2 satellite imagery by CREP for the near-shore areas (0-20 m depths) around Timor-Leste.

    Lineage Singlebeam bathymetry data collected using HydroLite-TM Echosounder Kit by Seafloor Systems, a small boat Hydro Survey System using Ohmex SonarMite echo sounder and Trimble ProXT receiver. Data was collected following procedures established by Seafloor Systems, and the HydroLite-TM system was tested and calibrated in advance of the surveys. Soundings were recorded in meters. Data collected in 2012 were processed using a different method from that used in 2013 as described in the process steps.
