EX1105: Field Trials of EM302 Multibeam Sonar Water Column Backscatter on NOAA Ship Okeanos Explorer

During this OER project in partnership with NOAA's National Marine Fisheries Service and the Bureau of Ocean Energy Management, Regulation, and Enforcement (BOEMRE), two ships will work collaboratively in the Gulf of Mexico to map known targets of man-made or natural seeps to test the use of their sensors to detect these seeps. The NOAA Ship Pisces will utilize its ME70 multibeam sonar sensor and the Okeanos Explorer will use its state-of-the-art Kongsberg EM302 multibeam sonar system and its newly acquired EK60 echosounder. Of special interest to the objectives of this mission is the water column backscatter data component of the EM302 multibeam survey system. These data will be analyzed as they are collected over known natural and man-made seeps in the Gulf of Mexico and, along with the data from the newly acquired EK60 echosounder, will be compared to those data collected by the Pisces ME70 and single beam sonar sensors.

Search Data
Distribution Formats
  • Kongsberg/Simrad instrument files (.raw or .wcd) (Version: 1)
    • File Specification: Kongsberg/Simrad .raw files are generated by ME70, EK60 or ES60 instruments. They contain power and optionally angular position data with each beam/frequency identified by an independent channel. See the Simrad interface specification manual for further information. The .wcd files are generated by Kongsberg EM302 or EM122 instruments. See Kongsberg documentation for more information.

Purpose By collecting and analyzing sonar data over known natural and man-made seeps in the Gulf of Mexico, a primary objective will be to determine the efficacy of the Okeanos Explorer's Kongsberg EM302 multibeam sonar system and its water column backscatter data for detecting seeps during exploration.
