Abstract:
Gridded (5 m cell size) bathymetry of the shelf and slope environments
of Howland Island, Pacific Remote Island Areas, Central Pacific.
Almost complete bottom coverage was achieved in depths between 8 and
3800 meters (5 m grid includes depths to 300 m). The bathymetry dataset
includes Simrad EM300, EM3002D, and Reson 8101ER multibeam data collected
between Jan. 28-29, 2006.
Purpose:
The data were collected in support of Coral Reef Conservation Program
goals to map all shallow (0-30 m) coral reefs in US Pacific waters and
priority moderate (> 30 m) depth areas by 2009. The data are being used to
provide bathymetric and backscatter data for previously unmapped areas;
in support of ecosystem management requirements for benthic habitat mapping
and location of Essential Fish Habitat; and to study the geologic features
of the area.
Supplemental_Information:
Data were collected aboard the NOAA Ship Hiialakai, a 218' United States
National Oceanographic and Atmospheric Administration research ship. The NOAA
Ship Hiialakai's survey sensors include a 300 kHz Simrad EM300 sonar
and a 3000 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. Sensor configuration for the Hi'ialakai
for cruise HI-06-01 is documented in the cruise/multibeam metadata file
HI0601_MB_Metadata.txt.
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. Sensor configuration for the AHI for cruise
AHI-06-01 is documented in the cruise/multibeam metadata file
AHI0601_MB_Metadata.txt.
