System Overview

The JRSO Bathy-2010 system is installed in the Underway Geophysics Lab and consists of a 10kw LPT Transmitter (located at the bottom of the rack), a Sonar Processor, and Windows computer. It is designed to provide the user full ocean depth bathymetry and sub-bottom profiling with a 3.5 kHz transducer array consisting of 12 transducers and a single 12 kHz transducer located in the sonar dome.  The sonar dome is attached to the ship’s hull forward of the moon pool, approximately where the gym is.

Assumptions

This quick start guide assumes that the U/W Technician has set up the file folders, application, and supporting infrastructure so that the Bathy2010 system is ready to use.  If this is not the case, see the Bathy2010 JRSO User Guide and the Bathy2010 manuals.

Bathy 2010 Application

Start up the Bathy-2010 application by double clicking the icon on the computer desktop or open from the Start menu. During start up, view the Sensor Status window located on the left side of the screen about 1/3 from the bottom. Once the status window indicates a “Sensor:Idle” message, you are now ready to start pinging and operate the system.  The main sonar screen looks like this.

• Verify that GPS data and time is updating in the windows in the upper left corner.  If they are not then refer to the Bathy2010 JRSO User Guide.

Open the Edit drop down menu and select “Configure Acquisition Parameters…” to set the Power Levels for Channel 1 (3.5 kHz) and/or Channel 2 (12 kHz) if in use.  From the drop down menu, select a power of -24 dB for Channel 1 to begin with and “Apply”.  Note that 0 dB is the maximum power output and drops down from there as a “-“ number. 
Note: The transducer power is intentially set low to begin with so that the transducers don’t start pinging loudly and abruptly.  Once the sonar is pinging, the power can be brought up stepwise to get a good return signal.  Go down to the upper tween and lower tween accommodations to hear what the sonar sounds like down there.
