ABSTRACT
This report outlines the research and subsequent software development to correct for beam pattern residuals in backscatter mosaics derived from the Kongsberg-Simrad EM300 multibeam system installed on the Canadian Coast Guard Ship Amundsen. Since 2003, the UNB Ocean Mapping Group (OMG) has been tasked with the acquisition, processing, management, and distribution of all hydrographic data from the ship as part of the Canadian Arctic Shelf Exchange Study and ArticNet projects organized and financed through the Natural Sciences and Engineering Research Council of Canada and the Canadian Foundation for Innovation. In addition to the typical bathymetric products available from multibeam sonar systems, backscatter mosaics are also needed to support other scientific objectives on board the vessel, particularly ongoing paleo-oceanographic research. This involves boxcore and piston-core samples taken from the surface and sub-surface of the seabed in the high Canadian arctic. Having accurate seafloor backscatter information is vital to choosing appropriate locations for these activities. It is therefore crucial to provide such backscatter products with all apparent changes in such products due to actual changes in seafloor geology and not due to beam pattern fluctuations from the sonar system. There is a great deal of calibration performed automatically by the Simrad system on raw backscatter data, and OMG beam correction software exists to further calibrate backscatter in several different ways. Even so, residual beam pattern effects still exist in the resulting mosaics from the Amundsen due to additional complications with the EM300. This report describes the ship and the ArcticNet program in general, discusses the technical details of the EM300 sonar system, and reviews some general and Simradspecific backscatter theory as well as current OMG beam pattern correction practices. Finally, it describes further research and software development created for this project to correct for residual beam pattern effects in the Amundsen EM300 data.
