- Abstract:
-
Gridded bathymetry (10m) of Kahoolawe Island, Hawaii, USA.
The data include multibeam bathymetry from the EM120, EM122, EM710, EM1020, and EM1002 multibeam sonar collected
by the Hawai'i Undersea Research Laboratory of the University of Hawaii in depths between -30 and -1300 meters.
Data processing was done for distribution by the NOAA Coral Reef Ecosystem Division.
- Purpose:
-
These ASCII grids were created using data gathered from multibeam soundings for documentation
and for use as a planning and reference document. Further data were collected to fill gaps in the
existing bathymetry. Refer to supplemental information for description of instrument and survey.
- Supplemental_Information:
-
Data were collected aboard the R/V Kilo Moana, a 186' Waterplane Area Twin Hull (SWATH) vessel owned by the U.S. Navy and operated by the University
of Hawaii Marine Center. The R/V Kilo Moana's survey sensors include a Simrad EM710: 70-100 kHz swath mapping, 10-1800 m depth range
Multibeam and a Simrad EM122: 12 kHz swath mapping, 300-11,000 m depth range which measure bathymetry and
acoustic backscatter imagery, a TSS/POS/MV 320 Model which measures time, position, velocity, attitude and
heading, and a Seabird SBE 19plus CTD used to measure sound velocity profiles. Specific equipment configurations are documented:

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
with a defined grid cell size (10 m) in SABER and area based
editing is performed. The edited PFM is then exported as X,Y,Z
data with a value at each grid node. The X,Y,Z data are then
gridded using nearneighbor, a Generic Mapping Tools (GMT)
algorithm that converts an ASCII or binary table to a netCDF grid
file format. NetCDF grids are then converted to an ArcGIS ASCII
file format using LINUX/UNIX commands in combination with GMT.
GMT is an open source collection of tools for manipulating
geographic data sets. Additional information about GMT can be
found at: http://www.soest.hawaii.edu/gmt and additional
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. Therefore, the accuracy of depth
measurements should be considered to be within 1 meter.
