2020 Okeanos Explorer EM304 SAT

CruiseID: 
EX2000

Summary

  1. The Okeanos Explorer received a Kongsberg EM304 multibeam echosounder topside upgrade over the 2019-20 winter maintenance period. No changes were made to the TX or RX arrays (installed in 2007 and 2018, respectively) or the Applanix POS MV positioning and attitude system.
  2. Sea acceptance testing (SAT) was conducted during EX2000 (March 3-8, 2020) with Kongsberg, NOAA, and OMAO personnel on board to complete the following procedures:
    • Review EM304 and POS MV system geometry

NOAA Ship Ruben Lasker ME70 Integration Testing

Executive Summary

The purpose of Coast Survey’s participation in this cruise was to verify the installation and configuration
of the ME70 and ancillary systems; validate the current Hypack implementation of the ME70 bottom
detection code; and provide operational guidance to the future operators of this system. The transit
from San Diego, CA to Neah Bay, WA offered an opportunity to test this system without interfering with
other planned science objectives. While we have used the Multibeam Sonar Acceptance Procedures as

NOAA Ship Fairweather Launch 2017 SAT

Executive Summary

We installed four Kongsberg EM2040 multibeam echo sounders, one on each of Fairweather’s
hydrographic survey launches during the spring of 2017 in Newport, OR. We accomplished the test and
qualification of these systems on Puget Sound from May 22 through May 26. Conditions were generally agreeable for testing with some wind driven chop potentially affecting a limited set of noise tests. All systems were successfully integrated and measured performance was in compliance with vendor specifications and suitable for conducting NOAA hydrographic surveys.

E/V Nautilus Spring 2017 Quality Assessment Report

Multibeam System: 
EM302
CruiseID: 
NA079
The E/V Nautilus undertook a multibeam echosounder quality assurance test from May 1 to May 5, 2017 during an engineering shakedown leg (NA079) in order to perform an assessment of the vessel’s Kongsberg EM302 multibeam echosounder. Data were collected near the Southern Channel Islands (Figure 1), offshore from San Pedro, California. Paul Johnson and Lindsay Gee provided logistical and technical support for mission planning, data collection, and analysis.
