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.

RV Sikuliaq 2016 Calibration Report

CruiseID:

SKQ201602S

The R/V Sikuliaq is equipped with Kongsberg Maritime (KM) EM302 (30 kHz) and EM710 (70-100 kHz) multibeam echosounders and a Seapath 320 positioning and attitude system with C-NAV DGNSS auxiliary input. These systems were reviewed by the Multibeam Advisory Committee (MAC) and personnel from NOAA, the University of Alaska Fairbanks (UAF), and Kongsberg Maritime (KM) during sea acceptance trials (SAT) in August 2014.

RV Bat Galim 2016 System Review

From 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:
