    User’s Manual Innomar SES Parametric Sub-bottom Profilers 6 How To ... 6.1 How to avoid the engine’s noise / proper transducer mounting General hints about transducer mounting are given in section 2.2 on page 14. The ship’s engines often cause mechanical vibrations of the entire hull of the ship. These vibrations can go to the transducer via its support and the hull can emit sound that causes noise in the SBP receiver, too.
  • Page 86 User’s Manual Innomar SES Parametric Sub-bottom Profilers To avoid the impact of noise by vibrations onto the transducer it should be mechanically decou- pled from the vessel. Especially the steel-to-steel connections on the flange and on the pipe should be decoupled using elastic material like rubber, plastics or wood. This is illustrated in the figures below.

    User’s Manual Innomar SES Parametric Sub-bottom Profilers A.12 Innomar SBP Data Acquisition and File Formats Innomar Data Acquisition Most I SBPs digitise the received signal of the LF channel at a sample rate of 96 kHz. NNOMAR The received HF signal is shifted into the LF band and data is then sampled similar to the LF data.
  • Page 184 How to convert 24-bit SES3 data files to SEG-Y format For using third-party post processing software, convert the SES3 files to SEG-Y format using Innomar’s “SESConvert” software, see chapter 9 on page 129. Make sure to enable “Interpolate Coordinates” and “Remove Coordinate Duplicates”.

  • Page 193 User’s Manual Innomar SES Parametric Sub-bottom Profilers Checklist Data Acquisition Settings In advance of any data collection the main question should be “What do I want to achieve?”, because different applications require different software settings. Most emphasis should be put on the hardware installation and on system settings that cannot be altered during post processing: frequency, signal length (pulses), range and gain.
  • Page 194 User’s Manual Innomar SES Parametric Sub-bottom Profilers Checklist Data Processing ISE Data Cleaning This should be done immediately after the survey, even if the data will be later converted into SEG-Y data format and processed using third-party software:  Check GNSS position data for outliers and clean if necessary.
