2019 Sikuliaq Calibration Report

Multibeam System: 
EM302
Multibeam System: 
EM710
CruiseID: 
SKQ201907T

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

  1. The Multibeam Advisory Committee (MAC) was asked to assist with Quality Assurance Testing (QAT) of the ship’s EM302 and EM710 ahead of the 2019 field season; due to scheduling constraints, MAC personnel (Kevin Jerram and TomerKetter) provided remote support for line planning and data analysis from shore
  2. MAC communication with SKQ personnel (Steven Roberts and Steven Hartz) commenced in spring 2019 with planning for calibrations (‘patch tests’) and accuracy testing for both systems during a transit from Newport to Astoria, OR
  3. The calibration and accuracy test plans were developed at sites successfully used for previous EM302 and EM710 testing aboard R/V Falkor(FK170602; not funded by NSF)
  4. This report describes the calibration results and implementation in SIS; additional swath accuracy and swath coverage processing using the full SKQ201907T dataset are ongoing, and this report will be updated as results become available 2
