Abstract

This multibeam backscatter sonar image of the sea floor (0-200 m water depths) was mosaiced from data collected fromvarious mapping efforts each October from 2001-2004. Reson 8101 (240 kHz) and Reson 8125 (455kHz) multibeam echosounders werehull mounted to survey launches and deployed from the NOAA ship Rainier. Either Trimble or CSI wireless DGPS were used forlaunch positioning. TSS or Applanix Pos/MV were used to compensate for vessel motion. A Seabird SVP 19 plus was used to correctfor sound velocity refraction. Navigation and line planning were accomplished with Hypack. Sonar packets, motion sensor, andnavigation data were logged in Isis Sonar as XTF files. Backscatter was normalized using propietary software developed by theUniversity of New Brunswick Ocean Mapping Group.

Description:	Microsoft Windows 2000 Version 5.0 (Build 2195) Service Pack 4; ESRI ArcCatalog 9.1.0.722

Horizontal Positional Accuracy:	Accuracy of the horizontal coordinates is on the order of 10-30m based on the uncertaintyin position of side scan sonar towfish relative to ships gps position. Horizontal layback is more accurate than lateral offsetssince any lateral offset in the towfish position (due to side currents) is unaccounted for in the layback calculations.
