Pacific Islands Fisheries Science Center, PIFSC Special Publication, SP-17-002, 234 p. https://doi.org/10.7289/V5/SP-PIFSC-17-002. 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. In 2011, NOAA and the United States Agency for International Development (USAID) Timor-Leste Mission formed a 5-year bi-lateral partnership agreement from 2012 to 2016, in support of the Government of Timor-Leste—particularly the Ministry of Agriculture and Fisheries (MAF)—by addressing significant information gaps in their nearshore marine ecosystems. Specifically, MAF asked NOAA to address the following questions: 1. Where are the nearshore marine resources? 2. What are the nearshore marine resources? 3. How are they changing over time and what threats are potentially causing these changes? 4. What approaches are needed to manage and conserve the nearshore marine resources? With financial support from USAID and in-kind support from the NOAA Coral Reef Conservation Program (CRCP), the NOAA Coral Reef Ecosystem Program (NOAA-CREP) conducted baseline ecosystem assessment surveys to inform ecosystem-based management planning in Timor-Leste. The primary activities conducted by NOAA to answer these questions included: 1. satellite mapping of nearshore habitats, 2. conducting coral reef ecosystem assessments, 3. establishing ecological baselines for climate change, and 4. building management capacity by developing a spatial data framework The singlebeam bathymetry data described herein resulted from the first activity to conduct satellite mapping for the nearshore waters around Timor-Leste.

HDOP is a measure of the geometric quality of a GPS satellite configuration in the sky. HDOP is a factor in determining the relative accuracy of a horizontal position. The smaller the DOP number, the better the geometry. 2013: The type and QA is provided in the dataset. Records with a type = L indicate the depth record includes the GPS location and has a QA = 1 (NMEA tag for GPS fix). There are two 'type = D' records for every 'type = L' record (D=Depth), because the sonar pings every half second, which is more frequent than the GPS. For the 'type=D' records, the higher the QA, the better the return signal strength. QA=70 is low signal strength (not as good), QA = 130 is high return signal strength (better). Quantitation Limits The HydroLite-TM Echosounder Kit, Sonarmite Echosounder has a depth range of 0.3 m – 75 m. Completeness Report Obviously erroneous data based on the coordinates were cleaned from the dataset (coordinates outside the expected range for Timor-Leste; 0,0 pairs, etc). Conceptual Consistency As the survey was not conducted to meet IHO standards, all users should independently analyze the dataset according to their own needs and standards to determine data usability. 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. GPS track data (NMEA) and depths were downloaded and processed/parsed in ArcGIS using a customized track processing script written in Python. A time offset was applied to capture local time in Timor-Leste in addition to Greenwich Mean Time (GMT). The processed/parsed data were exported to an Esri geodatabase and erroneous data were cleaned in ArcGIS. The cleaned data were exported to CSV to be archived. Ehses, Julia (808)725-5447 julia.ehses@noaa.gov processor During 2013 surveys, the system was calibrated for sound velocity. A log was kept during the surveys, including the offset from the instrument to the water surface (20 or 30 cm, depending on the vessel) and the sound velocity calibration status. The SonarMite data (.SOM) was downloaded from the instrument and imported into SonarVista, offsets and calibration were applied, obviously erroneous data based on the coordinates were removed, and the processed data were exported to CSV format. The exported data are considered 'lightly processed' and should be further inspected and cleaned before use.
