The Raw ADCP data files contain the data as the ADCP sent it out to TRANSECT This means the data is in the ADCP data format The description of this data format is found in the Ocean Surveyor Technical Manual Appendix D The Raw Navigation data files contain the data as the navigation device sent it out to TRANSECT Additionally there is a header in front of each block of navigation data that contains an ADCP ensemble number and PC time The PC time is not useful for most cases The ADCP raw ensemble number indicates that all data after this number was sent from the navigation de vice to TRANSECT during that particular ADCP ensemble This allows you to link the raw Navigation data to the raw ADCP data The format of the navigation data in this file is the same as what the navigation device sent out The Processed data or average data is the ADCP raw ensembles converted to earth coordinates and averaged over the time period set by you in the Planning Menu of TRANSECT This data also can contain navigation data when TRANSECT is used with NAVSOFT If NAVSOFT is not used there will be no navigation data in the file The format for the Processed data file is found in the TRANSECT manual Sometimes you may wish to average your data over a different time period than when you origi nally collected the data The only way to do this is to re average the Raw ADCP data over a dif ferent time period in the Playback Menu This data can then be stored in

5. THIS REGION WHICH INCLUDES A 15 DEGREE CONE AROUND THE BEAM Figure 15 Beam Clearance Zone 5 2 Vessel Mount Special Considerations Use the following suggestions when mounting the ADCP to a moving platform It is desirable to rigidly mount the ADCP to the vessel You want to avoid the free spin ning of the ADCP in this application The ADCP must stay in the water at all times The ADCP must be mounted deep enough so that turbulence caused by its movement through the water does not allow air bubbles to be attached to the transducer faces Avoid mounting the ADCP near motors and thrusters They cause air bubbles and will cause bias to the internal compass Avoid mountings that will cause the ADCP to see severe accelerations 22 RD Instruments 5 3 Test the ADCP This section explains how to test the ADCP with RDI s BBTALK program These tests thor oughly check the ADCP in a laboratory environment but are no substitute for a practice deploy ment These tests do not calibrate the ADCP You should test the ADCP When the ADCP is first received Before each deployment or every six months When instrument problems are suspected After each deployment These test procedures assume all equipment is working The tests can help you isolate problems to a major functional area of the ADCP For troubleshooting information see Chapter 6 of the Ocean Surveyor Technical Manual For help on using BBTALK see Chapter 5 of
