NOAA Ship Fairweather Launch 2017 SAT

Executive Summary

We installed four Kongsberg EM2040 multibeam echo sounders, one on each of Fairweather’s

Rainier

NOAA Ship Rainier 2013 Multibeam System Review

Sensor geometry reconfiguration was successfully completed and tested on Rainier and a 14 ms orientation time delay was applied in SIS to accommodate an observed latency in the transmission of motion data from the POSMV to SIS. We feel that these two modifications will improve the data quality with the geometry reconfiguration allowing for successful application of TrueHeave in postcprocessing and the time-delay configuration improving the data quality of soundings as corrected in real-time by SIS.

Falkor Fall 2014 Quality Assessment Report

The EM302 and EM710 multibeams were successfully calibrated and verified for use with both the loaner Seapath MRU and the new POS MV. Angular offsets were small except for the roll bias for both the EM710 and EM302. As both multibeam systems have the same large roll bias, it is likely the result of a shift in the mounting angle of the MRU. Both SIS acquisition systems have been updated with the new calibration results.

Falkor Spring 2014 Quality Assessment Report

The transducer impedances are similar to baseline measurements in 2012 and with those taken in 2013. Transducer conditions, based on these tests, are acceptable and there is no sign of degradation of the transducer arrays.

Noise levels for the EM710 remain unchanged and very low. Noise levels for the EM302 have increased at higher speeds though they remain low when the ship is stationary in the water, suggesting that the increase is associated with flow noise and/or the propulsion system.

NOAA Ship Rainier 2013 Multibeam System Review

Sensor geometry reconfiguration was successfully completed and tested on Rainier and a 14 ms orientation time delay was applied in SIS to accommodate an observed latency in the transmission of motion data from the POSMV to SIS. We feel that these two modifications will improve the data quality with the geometry reconfiguration allowing for successful application of TrueHeave in postcprocessing and the time-delay configuration improving the data quality of soundings as corrected in real-time by SIS.

2019 Armstrong EM122 and EM710 Calibration

Multibeam System:

EM122

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.

  • 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

2019 R/V Armstrong EM710 Calibration

Multibeam System:

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.

2014 QAT Review of R2R MBQA Tests

Overview

The Rolling Deck to Repository (R2R) Program has developed programmatic quality assessment (QA) routines intended to identify suspicious data that may indicate sensor and/or operational problems. In order to assess the results of these QA tests and seek fleet-wide patterns in system performance and operation, this page provides an initial summary the results of R2R Multibeam QA tests for all sonar systems.
