Title: EM300 Multibeam Sonar Data collected from May 7 to May 22 from NOAA Ship Hi'ialakai cruise HA-17-01 to the Commonwealth of Northern Mariana Islands (CNMI) and Guam in 2017
Short Name: Multibeam Data, Cruise HA-17-01
Status: Completed
Publication Date: 2018
Abstract:

Multibeam data were collected using a Simrad EM300 30-kHz sonar aboard NOAA Ship Hi'ialakai, a 68-m (218') NOAA research vessel, from May 7 to May 22, 2017 during cruise HA-17-01. Multibeam data were acquired at Guam and Aguijan in the Marianas. The multibeam data were collected using Kongsberg SIS software in the *.all format and processed using SABER and QPS Qimera editing software. Surface sound velocity values were supplied by Seabird SBE-45 MicroTSG and a SBE-38, and motion corrections from a TSS/Applanix POS MV (Model 320 Version 5) vertical reference were applied to the data in real time. WGS84 datum. The vessel is equipped with a sound velocity profiler and casts were acquired during mapping operations. However, because insufficient sound velocity profile data were collected at depth during surveys around Guam, sound velocity profile data were applied from an earlier survey (HI-07-02). At Aguijan, suitable sound velocity data were acquired; however, the surveyed areas were previously mapped and therefore the data for Aguijan was not processed. Depths mapped range from ~50 m to 1000 m. These data are not to be used for navigation.

Purpose:

The Pacific Islands Deep-Sea Coral and Sponge Initiative (PICSI) aimed to map and characterize deep-sea coral and sponge ecosystems of the Pacific Marine National Monuments in select areas of the U.S. Pacific Islands through systematic field surveys that utilize bathymetry and other seascape features to prioritize survey locations. Data collected by the NOAA Ecosystem Sciences Division (ESD) in 2017 was intended to gap-fill pre-existing bathymetry coverage around the U.S. Pacific Islands visited during ESD's Pacific Reef Assessment and Monitoring Program cruise to the Mariana Islands.

Supplemental Information:

The Hi'ialakai's survey sensors include a 30 kHz Simrad EM300 sonar and a 300 kHz Simrad EM3002d sonar, which measure bathymetry and acoustic backscatter imagery. However, due to instrument failure (faulty starboard transducer head on the EM3002d sonar) the data acquired with the EM3002d sonar will not be archived.

Resource Description: EM300 and EM3002D Multibeam Sonar Data from Cruise Hi'ialakai HA-17-01

Data Quality

Accuracy:

Horizontal_Positional_Accuracy_Value: 20 (no DGPS corrections applied)

Vertical_Positional_Accuracy_Value: Vertical accuracy is depth dependent (~0.5% of water depth).

Completeness Report:

Due to instrument failure (faulty starboard transducer head on the EM3002d sonar) the data acquired with the EM3002d sonar for the entire survey are not of use and will not be archived. All raw EM300 data were archived; however, EM300 data only covered new terrain around Guam, and therefore only the data for that area has been processed and incorporated into map products.

Conceptual Consistency:

These data are believed to be logically consistent though no tests were performed

Quality Control Procedures Employed:

- Surface sound velocity values were supplied by Seabird SBE-45 MicroTSG and a SBE-38, and motion corrections from a TSS/Applanix POS MV (Model 320 Version 5) vertical reference were applied to the data in real time.

- Vertical adjustments using sound-velocity corrections were applied from a prior survey (HI-07-02)

- Spurious data points were removed (automated and manual)

- Comparisons with previously acquired, overlapping data

Process Steps

Process Step 1

CC ID: 598321
Description:

-Raw data were acquired with Kongsberg SIS (*all)

-*all data were converted to *gsf within SABER processing software

-Vessel offset and sound velocity profile corrections were applied in SABER

-Corrected *gsf files were imported into QPS Qimera for editing and surface production

-Where data were of sufficient coverage and quality, a medium-tension spline filter was used to remove spurious data, and further manual editing was conducted to remove any remaining noise.

-Final surface grids were exported from Qimera to GeoTiff.

Docucomp UUID: 0571007e-297c-430c-a9d2-b56a3f225f99
Instrument / Gear: Instrument
Instrument Type: Multibeam Echosounder
Description:

The EM 300 multibeam echo sounder is designed to do mapping from 10 m depth to beyond the continental rises, including the shallower ocean basins. It operates down to more than 5000 m depth with swath widths up to about 5000 m. Small transducers and compact electronics make the installation easy, and the system accuracy is generally well within the IHO standards. The EM 300 is a complete system. All necessary sensor interfaces, data displays for quality control and sensor calibration, seabed visualization, and data logging are a standard part of the system, as is integrated seabed acoustical imaging capability (sidescan). The nominal sonar frequency is 30 kHz with an angular coverage sector of up to 150 degrees and 135 beams per ping as narrow as 1 degree. Achievable swath width on a flat bottom will normally be up to 5.5 times the water depth. The angular coverage sector and beam pointing angles may be set to vary automatically with depth according to achievable coverage. This maximizes the number of usable beams. The beam spacing is normally equidistant with equiangle available. The EM 300 multibeam system was in production from 1997 to 2007 and was replaced with the EM 302.

Platforms

Platform 1

CC ID: 715271
Identifier: NOAA Ship Hi‘ialakai
Description:

NOAA Ship Hi‘ialakai is a multipurpose oceanographic research vessel whose primary missions include coral reef ecosystem mapping, coral reef health and fish stock studies, and maritime heritage surveys in the Pacific Islands Region. A T-AGOS class vessel, Hi‘ialakai was built in 1984 for the U.S. Navy and served as the U.S. Naval Vessel Vindicator. The ship was then transferred to the U.S. Coast Guard, and finally to NOAA in 2002, when it was converted to conduct coral reef research. The ship was commissioned in the NOAA fleet in 2004.

The 224-ft. ship is renowned for its work since 2004 assessing the health of coral reefs throughout the Pacific Islands. Scuba diving operations play a major role in the ship’s mission, and Hi‘ialakai is equipped for both shallow- and deep-water dive projects. The ship carries three small workboats that transfer divers to the working grounds, a 15-person dive locker to store scientific gear and equipment, and an air compressor to fill tanks. As Hi‘ialakai frequently operates in remote areas, the ship also carries a three-person, double-lock decompression chamber. In the event of a diving accident, the diver can be treated onsite.

The ship supports a scientific crew of ~22 and is equipped with wet and dry labs, a computer/electronics room, and a scientific freezer. Data collection systems include an acoustic current Doppler profiler, CTDs and water samples, a thermosalinograph, and two Kongsberg multibeam echosounders (EM300 and EM3002d). The ship supported multibeam mapping operations across the Pacific Island Regions primarily between 2004 and 2008.

In addition to supporting NOAA projects, Hi‘ialakai works in partnership with the University of Hawaii, State of Hawaii, and the U.S. Fish and Wildlife Service. The ship is homeported at the NOAA Marine Operations Center-Pacific Islands in Honolulu.
