- Abstract:
-
Gridded (40 m cell size) bathymetry of
of Vailulu Seamount, an active volcano that lies between Ta'u Island and
Rose Atoll, American Samoa, South Pacific. Almost complete bottom coverage was
achieved in depths between 583 and 3017 meters. The bathymetry dataset
includes Simrad EM300 data collected during Feb. to March of 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
which provides 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.

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 per cent of water depth.
