Horizontal accuracy is ~5m (differential GPS correctors applied), vertical accuracy is depth dependent (~1% of water depth), WGS84 datum. These data are not to be used for navigation. Depths mapped range from 10 - 200 m.
The equipment serial numbers, software versions and sensor configuration settings are as follows:
RESON 8101-ER multibeam echosounder Transducer serial #: 201004 Firmware, dry: 8101-2.09-2E34D Firmware, wet: 8101-1.08-C215
POS/MV Model 320, version 4.0000 (w/ TrueHeave but no RTK) PCS serial #: 2514 IMU serial #: 203 Controller software: v 220.127.116.11 PCS Firmware: 3.41
Seabird SBE19 CTD: Serial #: 3029 Last Callibration: 08/2009
Lever Arm Distances and Alignment Offsets: THe Reference Point (RP) is defined to be the center of pivot on the pole mounted transducer system directly in line with the transducer. RP is located between the 20'and 28' 10" deck on the Oscaer Elten Sette. Positive X means the point is forward of the RP, positive Y means the point is to starboard of the RP, positive Z means the point is below the RP.
