Multibeam System: 
EM710
CruiseID: 
KM2008B

KM 2020 QAT Planning Overview

  • The University of Hawaii’s UNOLS vessel R/V Kilo Moana(KM) is equipped with Kongsberg Maritime EM122 and EM710 multibeam echosounders and an ApplanixPOS MV-320 v5 Ocean Master positioning / attitude system
  • The Multibeam Advisory Committee (MAC) was asked to assist with Quality Assurance Testing (QAT) of the ship’s multibeam echosoundersahead of the 2020 field season; due to widespread travel restrictions, MAC personnel provided remote support for line planning and data analysis from shore

2019 Armstrong EM122 and EM710 Calibration

Multibeam System: 
EM122
Multibeam System: 
EM710
CruiseID: 
AR42

Executive Summary

  1. Calibrations (‘patch tests’) were planned for the EM122 and EM710 multibeam echosounders on R/V Neil Armstrong during AR42-02 following the winter 2019-20 maintenance period. Calibration sites were developed opportunistically along a transit route in the vicinity of the western Florida escarpment.
  2. The EM710 was most recently calibrated during AR41 in November 2019; due to elevated sea state, the scope of AR41 was narrowed and the EM122 calibration planned for that cruise was removed from the schedule.

Atlantis Seapath Test 2019

Multibeam System: 
EM122
CruiseID: 
AT42-10

Executive Summary:

  1. R/V Atlantis EM122 multibeam data includes intermittent depth artifacts across the swath that do not appear to be correlated with roll, pitch, sound speed, latency, or other sensor integration errors. These were first brought to the attention of the Multibeam Advisory Committee (MAC) in late 2016, beginning a process of investigation to better define the problem and rule out a variety of potential causes.

2019 Okeanos Explorer EM302 Shakedown

Multibeam System: 
EM302
CruiseID: 
EX1902

Summary
The primary shakedown activities included:

  • 2019-05-12: depart Pascagoula, MS
  • EM302 and POS MV geometry / config. review
  • EM302 dockside BISTs (incl. TX channels)
  • Geometric calibration (‘patch test’)
  • Backscatter calibration (for Kongsberg processing)
  • Roll verification
  • Swath extinction data collection during transits
  • EM302 RX noise vs. speed testing
  • Acoustic interference testing across all systems
  • K-Sync SAT and testing with Kongsberg support

2019 R/V Armstrong EM710 Calibration

Multibeam System: 
EM710
CruiseID: 
AR41

Executive Summary

  1. Calibrations (‘patch tests’) were planned for the EM710 and EM122 multibeam echosounders on R/V Neil Armstrong in the vicinity of the continental shelf break south of WHOI for opportunistic testing in 2019. These tests were scheduled for AR41 in November; due to elevated sea state, AR41 was shortened and the EM122 calibration was removed from the schedule. After review of the system geometry and POS MV GAMS antenna calibration, the EM710 patch test was performed amid other science goals in the condensed schedule.
