Description:
Abstract:
Gridded (40 m cell size) bathymetry of Two Percent Bank (also called Tulaga Seamount) that lies between southeast of Tutuila, American Samoa, South Pacific. Almost complete bottom coverage was achieved in depths between 78 and 2221 meters. The bathymetry dataset includes Simrad EM300 and EM3002 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 and a 300 kHZ EM3002 sonar both of 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.

Overview_Description:
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 per cent of water depth.
