Pacific Islands Benthic Habitat Mapping Center (PIBHMC), Coral Reef Ecosystem Division (CRED), Pacific Islands Fisheries Science Center (PIFSC), National Marine Fisheries Service (NMFS), National Oceanic and Atmospheric Administration (NOAA) 20060907 Generic Sensor Format (GSF) digital data http://www.soest.hawaii.edu/pibhmc/ EM300 and EM3002D multibeam Data were collected in 10-13 Feb. and 18 Feb-13 Mar 2006 aboard NOAA Ship Hi'ialakai in American Samoa at Swains Island, Tutuila, the Manu'a Group, Muli Seamount (also known as East Bank), Tulaga Seamount (also known as Southwest Bank), Vailulu'u Seamount and Rose Atoll during cruise HI-06-02 These multibeam data were collected using SAIC ISS-2000 software in the Generic Sensor Format and processed using SABER editing software. Surface sound velocity values were supplied by a Seabird SBE-45 MicroTSG and a SBE-38 remote temperature probe. Sound velocity corrections from a Seabird 911 CTD sensor and motion corrections from a POS-MV vertical reference were applied to the data in real time. Predicted tides were applied to the data in real time: at Tutuila, Muli, Tulago, Vailulu'u and the Manu'a Islands, Pago Pago (170000) predicted tides were used with no corrections; at Rose Atoll, Pago Pago tides were used with +0.1 hr time correction and a range ratio of 0.92; and at Swains Island, Pago Pago predicted tides were used with a -0.5 hr time correction and a 1.12 range ratio. Horizontal accuracy is 20m (no differential GPS correctors applied), vertical accuracy is depth dependent (~1% of water depth). WGS84 datum. These data are not to be used for navigation. Depths mapped range from 20 - 4800 m. Concurrent mapping was done by the R/V AHI in water depths ranging from 10-250 m with the data set being AHI-06-02; metadata for AHI-06-02 are submitted separately. The data were collected in support of Coral Reef Conservation Program goals to map all shallow (0-30 m) coral reefs in US Pacific waters and priority moderate (> 30 m) depth areas by 2009. The data are being used to provide bathymetric and backscatter data for previously unmapped areas; in support of ecosystem management requirements for benthic habitat mapping and location of Essential Fish Habitat; and to study the geologic features of the area. Data were collected aboard the NOAA Ship Hi'ialakai, a 68 m (218') United States National Oceanographic and Atmospheric Agency (NOAA) research ship. The NOAA Ship Hiialakai's survey sensors include a 30 kHz Simrad EM300 sonar and a 300 kHz Simrad EM3002d sonar, which measures bathymetry and acoustic backscatter imagery, a TSS/Applanix POS/MV Model 320, which measures time, position, velocity, attitude and heading, and a Seabird SBE 9/11 plus CTD used to measure sound velocity profiles. The Hi'ialakai's equipment serial numbers, software versions and sensor configuration settings are as follows: SIMRAD EM300 multibeam echosounder Serial #: 303 PU Software Versions: 1.1.3 040427,2.0.0 040614,2.3.2 040615,2.0.1 040629 SIS Software Version: 1.0, build 117, July 2, 2004 SIMRAD EM3002D multibeam echosounders Serial #: 357 and 353 PU Software Versions: HCT: 2.0.7 040906 BSP67 Master: 1.2.7 040830 BSP67 Slave: 1.2.7 040830 PU: 1.6.8 050118 DDS: 3.17 2004/06/11 SIS Software Version: 2.5, build 47, April 1, 2005 HI'IALAKAI POS/MV Model 320, version 3 PCS serial #: 817, 474 and 295* IMU serial #: 1333 PCS Firmware: 2.16, Sep 15, 2004 and 2.21, Feb 02, 2006* Controller software: v 2.1 Seabird SBE 9/11 plus CTD: Serial #: 09P35130-0737 *Two problems were encountered with the POS/MV during this cruise. On the evening of Feb 17th (local time) the ship's POS/MV started continually rebooting. With assistance from Applanix we determined that the problem was isolated to the PCS, the rack-mounted controller box. The failed PCS has serial number 817. We moved the PCS(SN 474) from the R/V AHI to the ship after replacing the amplifier that provides power to the IMU (normally the PCS is equipped with a 24VDC supply by the ship's PCS has a 28VDC supply to drive the 50 m cable to the IMU) and were able to continue to survey. Because the IMU was not moved no recalibration was required. The PCS was moved between the ship and the AHI daily, allowing the ship to survey at night and the AHI to survey during the day. The settings for each configuration were saved to disk and reloaded at the beginning of each session. This continued until Feb 24th when a replacement unit arrived; this is SN 295. A second problem was that at some times the POS/MV would provide two different date stamps for the data, one time would be reported out the serial data stream and a different one reported out the Ethernet data stream. When this occurred the sonar data would have different time tags than the data recorded by the ISS2000 and data logging would fail. If the POS/MV was powered off and restarted the erroneous date stamp would usually disappear. Appalanix provided new firmware (v 2.21) to fix this problem, which was caused by GPS and UTC times diverging from each other by an additional second. This new firmware was installed on Feb 25th. Hi'ialakai Lever Arm Distances and Alignment Offsets: The Hi'ialakai's Reference Point (RP) is a granite block situated 1.222 m starboard of the ship's centerline, 1.23 m above the ship's baseline/datum on the keel. The RP is located under the forward deck, in the ship's laundry room. The ship's sensors, the sonar systems and permanent benchmarks are measured with respect to the RP. Positive X means the point is forward of the RP, positive Y means the point is to starboard of the RP, positive Z means the point is below the RP. The survey waterline is defined to be at the 15' draft mark on the vessel's starboard side.
