Introduction


The Whole Round Multisensor Logger (WRMSL) and Special Track Multisensor Logger (STMSL) are two whole-round systems which allow simultaneous measurements of density, magnetic susceptibility and Pwave velocity. The WRMSL and STMSL are the only two systems, which allow continuous core sections measurements, one after another.
Note: Both tracks function the same way; however, WRMSL measures density, magnetic susceptibility and P wave velocity, whereas STMSL only measures density and magnetic susceptibility.


Procedures

  1. Double-click the MUT icon on the desktop (Figure 1a) and login using ship credentials. For more information see the "Uploading Data to LIMS" section below.
  2. Double-click the IMS icon (Figure 1b). IMS initialize's the instrument and checks the movement of the track. Once initialized, the logger is ready to measure the first section.

Note: For Calibration of the GRA and the Pwave, please see the WRMSL & STMSL User Guide.

  1. To set the measurement parameters for each instrument, select DAQ > Measurement Editor.

Note: Always set measurement intervals as whole number divisors of the distance between the sensors (30cm), or the movement routine will be highly inefficient. Standard intervals are 2.5 or 5 cm.

2. In the Measurement Editor window, select the Instrument you wish to configure and then click in the Parameters window (Figure 2).



Figure 2.- Instrument Parameters window.

3. In the intrument DAQ Parameters window the user may alter the settings for each instrument (Measurement Interval, Edge, Acquisition Time, Setting the Instrument Online or Offline and Setting the Control of the measurements On or Off). Select Accept Changes. The changes will be written to the configuration file.

4. Select Finished in the Measurement Editor window. Check that the System Status and DAQ Parameters displayed on the main interface window (left side of page) have updated to the values specified.


  1. Core sections measured on the WRMSL and STMSL can be run either immediately after "Core on Deck" or after they have reached temperature equilibrium. The only caveat, is that Pwave velocity, cannot be run "cold" and should only be measured at room temperature (~ 19°C). Temperature equilibrium takes approximately 4 hours.


Note: If you would like to change measurement parameters, please contact the PP technician

  1. Place section in core tray. Make sure sections are oriented with the blue endcap facing towards the instruments (Figure ).
  2. Click START. The Section Information screen is displayed
  3. Place the curson in the SCAN field and scan the section label. SAMPLE ID and LIMS ID automatically fills. These ID tags contain information on expedition, site, hole, core, section number and length (Figure 4).

Additional entry field options are the LIMS and MANUAL tags.

  1. Click MEASURE.
  2. Core sections will be measured in sequence from the first to last section, not including the core catcher. Each section will move through the instrument by a pusher.
  3. Once the core section has reached its furthest limit, the pusher will return to its home position and the Section information screen will be displayed.

Note: During a measurement, the Pwave parameter: stack can be adjusted. For more details, please see below.

  1. Place the next section on the track. Repeat steps 3 and 4. Continue until all sections are measured.

Note: It is HIGHLY recommended that sections be measured IN ORDER.

  1. After the last section is measured, place the Pusher End Sequence (water core standard) on the track (Figure ).
  2. Click Pusher End Sequence. The standard will push the final section through the sensors and two standard measurements are taken (each sensor).
  3. All instrument data (density, magnetic susceptibility, Pwave velocity) are stored in C:\DATA\IN.
  4. Data is automatically uploaed to the LIMS database, and is available to view on LORE and LIVE. If data is not instantly visible, please contact the PP technician.

  1. In the Measurement Editor window, select the instrument you wish to configure and then click in the Instrument Parameters window (Figure ).
  2. In the DAQ Parameters window the user may alter the settings for each instrument (Measurement Interval, Edge, Acquire Time, Setting the Instrument Online or Offline, Setting the Control of the measurements On or Off). Select OK. The changes will be written to the configuration file.

Note: If you hit return, it selects the CANCEL CHANGES button. You must click on the ACCEPT CHANGES button to apply changes.

  1. Select Finished in the Measurement Editor window. Check that the System Status and DAQ Parameters displayed on the main interface window (left side of page) have updated to the values specified.
