Gridded bathymetry at 40m resolution surrounding Howland Island, within the Pacific Remote Island Areas - Central Pacific Ocean. Bottom coverage was achieved in depths between 8 and 3800 meters. The Arc ASCII grids and floating point geotifs include multibeam bathymetry data acquired over multiple surveys by the NOAA Ecosystem Sciences Division (as of April 2015). The data were acquired using the Simrad EM300, EM3002D, and Reson 8101 multibeam sonars, with sonar frequencies of 30, 300, and 240 kHz respectively.
These ASCII and floating point grids were created using data gathered from multibeam soundings for use as a planning and reference document. The data are also being used for benthic habitat mapping, for locating Essential Fish Habitat (as defined by NOAA Fisheries), and for studying geologic features of the area. Refer to supplemental information for description of instrument and survey.

Bathymetry collected in 2015 aboard the NOAA Ship Hi'ialakai | Currentness: Ground Condition
2015
Multibeam data were collected aboard the NOAA Ship Hi'ialakai, a 218' NOAA research ship. The NOAA Ship Hi'ialakai's survey sensors include a 30 kHz Simrad EM300 sonar and a 300 kHz Simrad EM3002d sonar, which provide bathymetry and imagery data, a TSS/Applanix POS/MV Model 320, which measures position, velocity, attitude and heading, and a Seabird SBE 9/11 plus CTD used to measure sound velocity profiles.
Multibeam data were also collected aboard the R/V AHI (Acoustic Habitat Investigator), a 25' survey launch owned and operated by the NOAA Pacific Islands Fisheries Science Center in Honolulu, HI. The R/V AHI's survey sensors include a 240 kHz RESON 8101-ER sonar providing bathymetry and imagery data, a TSS/Applanix POS/MV Model 320 which measures position, velocity, attitude and heading, and a Seabird SBE 19 CTD used to measure sound velocity profiles.
Specific equipment configurations are documented in metadata from cruises HI-06-01, AHI-06-01, and HA-15-01. These metadata can be accessed at: http://www.soest.hawaii.edu/pibhmc/cms/cruise-catalog/.

dataset
Accuracy
Relevant offset, sound velocity, and tidal corrections are applied to the data as part of the processing procedures.
Completeness Report
Data collected in 2015 were only used to gap fill the existing 40m bathymetry grid from data previously collected in 2006.
Conceptual Consistency
These data are believed to be logically consistent though no tests were performed
Process to produce bathymetry grid from source multibeam bathymetry data.
As multibeam bathymetry data contributing to grid were acquired over multiple surveys/years, there have been different methods employed to process the data. Generally speaking, data acquired prior to 2015 were treated according to protocol #1, whereas data acquired after 2015 were processed using protocol #2.
Protocol 1: Multibeam swath files are acquired in the Generic Sensor Format (GSF) and are edited on a swath by swath basis using SAIC's SABER editing software. The edited swath files are then combined into a Pure File Magic (PFM) format in SABER and area based editing is performed. The edited PFM is then exported as X,Y,Z. The resulting X,Y,Z data are then gridded using xyz2grd, a Generic Mapping Tools (GMT) algorithm that converts an ASCII or binary table to a netCDF grid file format. GMT is an open source collection of tools for manipulating geographic data sets. Grid nodes with more than one value are set to the average value and unconstrained nodes are set to NaN. Finally, the netCDF grid is clipped at a depth that minimizes data gaps for the specified grid cell size and then converted to an ArcGIS ASCII file format using LINUX/UNIX commands in combination with GMT.
Protocol 2: Multibeam bathymetry data were acquired in Kongsberg *.all format, and imported into SABER editing software as converted *gsf. Within SABER, relevant offset, sound velocity, and tidal corrections are made prior to exporting *gsf files to QPS Quimera for swath editing. Within Quimera *gsf files are combined to form 60m resolution 'Dynamic Surface'. A medium-tension spline filter is applied to the data, and the Dynamic Surface is progressively corrected as final 2D and 3D direct swath edits are made. The final cleaned surface is exported as a floating point geotif, where in ArcGIS it is merged with the pre-existing 60m resolution grid using the 'Mosaic to new Raster' function. This final combined grid is exported as both ArcGIS ASCII grid and a floating point raster grid.
Further information about the multibeam data processing is recorded in the cruise metadata.
