Description:
Abstract:
This is a high-resolution (1m) bathymetric grid with negative z values. The data were collected by the USF Center for Coastal Ocean Mapping with the Kongsberg Simrad EM 3000 multibeam system (Co-chief Scientists, David Naar and Brian Donahue). An Applanix POSMV 320 V3 system was used for real-time positions and vessel attitude (heading, pitch, roll, and heave). An AML (Applied Microsystems LTD.) SV plus was used to measure sound velocities in the water column. The data were collected on Taema Bank on November 9th, 2002 aboard a Motor Vessel Lady Ana.
Purpose:
This grid is a base layer for the purposes of visual overlay and comparison with other data sets around Tutuila and subsequent spatial analyses.

Data_Quality_Information:
Attribute_Accuracy:
Attribute_Accuracy_Report:
Soundings have been "cleaned" with a 2nd standard deviation filter to flag outliers (i.e., points beyond the 2nd standard deviation in Simrad bin stat post processing were flagged or removed). Tidal corrections: NOAA, verified, downloaded tide data, preliminary pressure water level data (N1) data are in meters above MLLW datum from station 1770000, Pago Pago, AS. Data have not yet been corrected with differential GPS.
Logical_Consistency_Report:
These data are believed to be logically consistent, though no tests were performed.
