- Abstract:
-
4-m grid of bathymetric data of Kaneohe Bay, Windward Side Oahu, Main Hawaiian Islands, USA.
These netCDF and ASCII grids include multibeam bathymetry from the Reson 8101 multibeam sonar collected by the
National Oceanic and Atmospheric Administration (NOAA) survey launch Acoustic Habitat Investigator (AHI) in 2009
and 2010 in Kaneohe Bay, Oahu by the NOAA Coral Reef Ecosystem Division in depths between 5 and 50 meters.
The 4-m grid also contains bathymetric Light Detecting and Ranging (LiDAR) data collected by the US Army Corps
of Engineers (ACOE) in 2000 and 2007.
- Purpose:
-
These netCDF and ASCII grids were created using data gathered from
multibeam and LiDAR depth measurements for use as a planning and reference document. The data
are also being used for benthic habitat mapping, for locating Essential Fish
Habitat, and for studying geologic features of the area. Refer to supplemental information for description of instrument and survey.
- Supplemental_Information:
-
Multibeam data were 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. These metadata can be accessed at:
http://www.soest.hawaii.edu/pibhmc/cms/cruise-catalog/
The 4m gridded bathymetric LiDAR data were collected by the ACOE and metadata for these can be found at
http://shoals.sam.usace.army.mil/hawaii/pages/Oahu.htm and at

- Attribute_Accuracy_Report:
-
Data are collected for resource management
and research purposes and are tested for internal consistency; however,
no effort is made to compare these data to external references or to
other published data.
- Logical_Consistency_Report:
-
These data are believed to be logically consistent
though no tests were performed, with the following exception. 2009 multibeam
data were collected during transits in and out of Kaneohe Bay at varying surveys speeds and
were not compensated for settlement and squat. Thus some depth discrepancies occur between
the 2009 and 2010 data sets, which were not completely resolved during processing.

- Process_Description:
-
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 2-m Pure File Magic (PFM) format
in SABER and area based editing is performed. The edited PFM 2-m was then exported
as X,Y,Z. The XYZ files were read into Global Mapper, a commercial application,
combined with the 4-m ACOE LiDAR data, and exported as an ArcASCII file and imported
into ArcGIS . aAdditional information about the multibeam data
processing is recorded in the cruise metadata.

- Entity_and_Attribute_Overview:
-
Depth values are real values based on the average of the
soundings that fell within the extracted grid cells. The number of
soundings per grid cell range from >1000 soundings in shallow depths
to as few as 20 soundings in deeper areas. A total error budget for
this survey has not been developed, but there are known inconsistencies between the
2009 and 20010 multibeam data. Therefore, the accuracy of depth
measurements should be considered to be within 2 meters.

These data can be downloaded as either a 2-D binary netCDF raster
grid or an ArcGIS ASCII text file. The netCDF grid
is the default grid file format used by GMT (Generic Mapping
Tools), which created this file. More information can be located
at http://www.soest.hawaii.edu/gmt/and
http://www.unidata.ucar.edu/software/netcdf/. The Arc ASCII file,
for use in ESRI's (http://www.esri.com) GIS software, can be
