50856 Entity Published / External 25307 Depth soundings from a single beam echo sounder collected around the nearshore areas of Timor-Leste in 2012 and 2013 Data Set Completed Singlebeam bathymetry for Timor-Leste Data Table Yes Singlebeam bathymetry for Timor-Leste DATETIME DATETIME No No Active 2013: the date and time (GMT) in mm/dd/yyyy hh:mm:ss format Z NUMERIC No No Active 2013: Unknown FixType NUMERIC No No Active 2012: Type of position fix (0 = No fix, 1 = GPS fix, 2 = DGPS fix) GMTime DATETIME No No Active 2012: Greenwich Mean Time (mm/dd/yyyy hh:mm) HDOP NUMERIC No No Active 2012: horizontal dilution of precision, or the relative accuracy of the horizontal position. 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. Island TEXT No No Active 2012: The island location in the pacific where surveys were conducted (Timor-leste) Latitude NUMERIC No No Active 2012: Y-coordinate in decimal degrees LocalTime DATETIME No No Active 2012: GMT (Greenwich Mean Time) +9 for local time in Timor-leste (mm/dd/yyyy hh:mm) Longitude NUMERIC No No Active 2012: X-coordinate in decimal degrees NumSatellites NUMERIC No No Active 2012: number of satellites in use (tracked by the GPS at the time of the position was fixed/recorded) QA INTEGER No No Active 2013: Records with a type = L indicate the depth record includes the GPS location and has a QA = 1 (NMEA tag for GPS fix). 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). Region TEXT No No Active 2012: The region location in the pacific where surveys were conducted (Coral Triangle) SEC NUMERIC No No Active 2013: sub-seconds (ss.0) SeafloorDepth NUMERIC No No Active 2012: Depth in meters, 0 to -30m TIDE NUMERIC No No Active 2013: Not used TYPE TEXT No No Active 2013: Type of record, D = Depth only, L= Depth and Location (depth is linked to GPS fix). There are two 'type = D' records for every 'type = L' record, because the sonar pings every half second, which is more frequent than the GPS. X NUMERIC No No Active 2013: Longitude in decimal degrees Y NUMERIC No No Active 2013: Latitude in decimal degrees DEPTH NUMERIC No No Active 2013: corrected depth in meters (20 cm or 30 cm correction applied, distance from instrument to surface of water) gov.noaa.nmfs.inport:50856 Annette DesRochers 2017-12-21T22:19:53 SysAdmin InPortAdmin 2022-08-09T17:11:38 2018-04-27 Pacific Islands Fisheries Science Center PIFSC 1845 Wasp Blvd. Honolulu HI 96818 USA 808-725-5300 https://www.pifsc.noaa.gov 8:00 a.m. - 4:30 p.m. 1001 Public No 2018-04-27 1 Year 2019-04-27
