Abstract:
Gridded bathymetry (40 m cell size) of the slope environment of
Swains Island, American Samoa. Almost complete bottom coverage was achieved
in depths between 7 and 4800 m. The multibeam data are from the Simrad EM300
system aboard the NOAA Ship Hi'ialakai, and the Reson 8101ER system aboard the
R/V AHI and were collected from 10th - 13th February 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 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. Sensor configuration for the Hi'ialakai for
cruise HI-06-02 is documented in the cruise/multibeam metadata file
HI0602_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-06-02
is documented in the cruise/multibeam metadata file AHI0602_MB_Metadata.txt.
