Abstract:
Gridded bathymetry of the submarine volcanos between Olosega and Ta'u Islands of the Manu'a Island group, American Samoa This survey provides almost complete coverage between 20 and 350 meters. The multibeam data are from Reson 8101ER system aboard the R/V AHI and were collected during Jan. to March of 2004.
Purpose:
This grid was created using data gathered from multibeam soundings for use as a planning and reference document. Refer to supplemental information for description of instrument and survey.
Supplemental_Information:
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, 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 AHI0402 is documented in the cruise/multibeam metadata file AHI0402_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. 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 meter.
