RV Bat Galim 2016 System Review
06/24/2016 — adminFrom January 31st to February 4th, 2016 a Shipboard Acceptance Testing (SAT) was conducted on the R/V Bat Galim, owned by the Ministry of National Infrastructures, Energy and Water Resource of Israel and operated by Israel Oceanographic and Limnological Research, on the newly installed Kongsberg Maritime (KM) EM302 (30 kHz) and EM2040 (200 kHz, 300 kHz, and 400 kHz) multibeam echosounders. These systems were thoroughly reviewed for system geometry, calibration, configuration, and performance during this acceptance period. Documented in this report are:
Nathaniel B. Palmer 2015 Sea Acceptance Report
11/04/2015 — adminExecutive Summary
The research vessel icebreaker (RVIB) Nathaniel B. Palmer (NBP) undertook cruise NBP1505 in the vicinity of the continental shelf break between Talcahuano and Puerto Montt, Chile, from June 10-15, 2015 (Fig. 1) in order to assess performance of the vessel’s 12-kHz multibeam echosounder (MBES). The MBES consists of a Kongsberg Maritime (KM) EM122 transceiver installed in June 2014 and transmit (TX) and receive (RX) arrays installed in June 2015, prior to NBP1505.

NOAA Ship Fairweather 2015 SAT
05/15/2015 — adminExecutive Summary
A Kongsberg EM710 multibeam echosounder was installed on the NOAA Ship Fairweather by Bay Ship and Yacht Co. of Alameda, CA in December, 2014. This mapping sonar replaced a Reson 8160 and a Reson 7111.
The performance of the EM710 was evaluated during sea‐trials from 9 February to 13 February, 2015. The performance of this system as installed and integrated meets the manufacturer specification and is adequate to meet the intended charting mission. All modes of operation were tested between 50 and 500 meters.
Sikuliaq 2014 Sea Acceptance Report
11/19/2014 — adminThe multibeam systems and attendant sensors on R/V Sikuliaq were successfully evaluated. The installation and integration of the systems is compliant with current best-practices and there are no major deficiencies that should hinder anticipated missions. Installation parameters and configurations of the systems have been verified and all patch-tests have been completed and loaded to the systems. As configured at the end of the SAT cruise and as detailed in this report, the systems are ready for generalized mapping activities including bathymetry, seafloor backscatter, and water-column work.
Nathaniel B. Palmer 2014 Sea Acceptance Report
11/19/2014 — adminThe Kongsberg Maritime (KM) EM120 multibeam echosounder (MBES) aboard the RVIB Nathaniel B. Palmer (NBP), installed in 2002, recently received two upgrades through the installation of a KM Seapath 330 position and attitude sensor (November, 2013) and replacement of the original EM120 transceiver with an EM122 transceiver (June, 2014).
Hugh R. Sharp 2012 Sea Acceptance Report
01/31/2013 — adminThe Reson 7125 system is correctly installed and integrated with the POSMV and Hypack acquisition system and there is no indication of errors in the integration of the systems. There remains uncertainty in the absolute accuracy of the depths due to the inadequately documented sonar z-offset calculation. High quality surveys were collected during the cruise immediately following Hurricane Sandy (Nov. 10, 2012) and attest to the quality of the installation and the integration of the survey system components.
Kilo Moana 2012 Sea Acceptance Report
07/13/2012 — adminThe EM122 and EM710 systems both appear to be configured correctly and, for the most part, adequately calibrated. Small MRU roll alignment residuals do exist and it is recommended that these be confirmed as soon as possible through acquisition of a pair of reciprocal survey lines over a flat and featureless seafloor. Verification lines should have been run for calibration tests for both systems, however, time constraints on the cruise schedule precluded this. It is standard practice to run verification lines.
Thompson 2010 Sea Acceptance Report
06/04/2012 — adminA sea acceptance trial (SAT) was conducted to evaluate the performance of the EM302 multibeam echosounder (MBES) onboard the R/V Thomas G. Thompson in October 2010 off the coast of Washington state. Excellent sea conditions permitted continuous acquisition with all planned survey sites being successfully mapped. It is the intent of this report to document the results of the SAT and to provide recommendations on further improvements that can be made to maximize the performance and accuracy of the system for both bathymetric and acoustic backscatter measurements.
