Summary
Abstract: Antarctic Multibeam Bathymetry and Geophysical Data Synthesis (AMBS) delivers shaded relief maps, bathymetry grids, multibeam bathymetry field data and other geophysical data from the Southern Ocean, primarily collected with the R/V N. B. Palmer. This effort initiated in 2003 with support of the Office of Polar Programs at the National Science Foundation. To learn more view the R/V Palmer Data ... View entire text

Quality LOGICAL CONSISTENCY REPORT: These data have not been quantitatively compared to previous hydrographic data, although they generally agree with qualitative comparison of published NOAA charts.

HORIZONTAL POSITIONAL ACCURACY REPORT: All of the NOAA survey vessels were equipped with Trimble DSM212L Differential Global Positioning System (DGPS) receivers. Launch 1005, which collected all of the multibeam bathymetry, was also equipped with a TSS POS/MV Model 320 (Position and Orientation System for Marine Vessels). Standard bathymetric processing, including tide corrections, soundings accuracy, and quality control were done by the NOAA Office of Coast Survey.
