2020 Sikuliaq EM302/EM710 Calibration Report

Multibeam System:





SKQ202008S Planning Overview

  • The University of Alaska’s UNOLS vessel R/V Sikuliaq(SKQ) is equipped with Kongsberg Maritime EM302 and EM710 multibeam echosounders and a Seapath320 positioning / attitude system
  • The Multibeam Advisory Committee (MAC) was asked to assist with Quality Assurance Testing (QAT) of the ship’s EM302 and EM710 ahead of the 2020 field season; due to widespread travel restrictions, MAC personnel provided remote support for line planning and data analysis from shore
  • MAC communication with SKQ personnel (Steven Hartz) commenced in spring 2020 with planning for calibrations (‘patch tests’) for both systems near Seward, Alaska
  • The calibration test plan was developed using suitable seafloor features in depth ranges appropriate for simultaneous data collection with both systems; shallow and deep roll sites were added for verification
  • This report describes the calibration results and implementation in SIS
