Description:
Abstract:
Multibeam backscatter imagery extracted from gridded
bathymetry of Midway Atoll, Northwestern Hawaiian Islands, USA.
These data provide coverage between 0 and 200 meters. The
backscatter dataset includes data collected using the Reson 8101
multibeam sonar. The sonars frequency is 240 kHz. These metadata
are for the 1 m grid cell size Reson 8101 multibeam backscatter
data only.
Purpose:
The GeoTIFFs of backscatter imagery 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, 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,
Hawaii. The R/V AHI's survey sensors include a 240 kHz Reson
8101-ER sonar providing multibeam bathymetry and backscatter
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 AHI0306,
HI0503, and HI0609. These metadata can be accessed at:
