Title:
Reson 8101ER Multibeam Sonar Data from Cruise SE1002 Commonwealth of the Northern Mariana Islands and Guam
Abstract:
Reson 8101ER multibeam Data were collected in February 11 - March 14, 2010 aboard NOAA Ship Oscar Elton Sette in the Commonwealth of the Northern Mariana Islands and Guam on cruise SE1002. These multibeam data were collected using SAIC ISS-2000 v 4.0.0.3.0 software in the Generic Sensor Format and processed using SABER editing software. Sound velocity corrections from a Seabird SBE19 CTD sensor and motion corrections from a POS-MV vertical reference were applied to the data in real time. Predicted tides were applied to the data in real time and observed tides were applied during post-processing.

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.

Supplemental_Information:
Data were collected aboard the NOAA vessel Oscar Elton Sette, a 68 m (224') United States National Oceanographic and Atmospheric Agency (NOAA) research ship. The Oscar Elton Sette deployed an over the side pole mounted survey sensors system including a 240 kHz RESON 8101-ER sonar which measures bathymetry and acoustic backscatter imagery, a TSS/Applanix POS/MV Model 320 which measures time, position, velocity, attitude and heading, and a Seabird SBE 19 CTD used to measure sound velocity profiles.

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 3.4.0.0 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.
