Mark Variables
Mark Variables allows you set up SEASAVE to copy the most recent scan
of data to a mark (.mrk) file as desired during real-time data acquisition.
SEASAVE writes the sequential mark number, system time, and all
selected variables to a .mrk file each time Mark Scan is clicked during data
acquisition. If a plot display is set up to show mark lines, SEASAVE also
draws a horizontal line in the plot each time Mark Scan is clicked during
data acquisition.
The .mrk file can be used to manually note water sampler bottle firings,
compare CTD data with data acquired at the same time from a
Thermosalinograph, or mark significant events in the cast (winch problems,
large waves causing ship heave, etc.) for later review and analysis of the data.
To enable and set up Mark Variables, click Configure Outputs. In the
Configure Outputs dialog box, click the Mark Variables tab:
Make the desired selections. Click OK or click another tab in
Configure Outputs.
To set up a plot display to show mark lines (lines can be labeled with the
sequential mark number and/or pressure) - Right click in the desired plot
window. In the Plot Display dialog box, select Show Mark Lines. Change
other settings as desired, and click OK (see Plot Display in Section 7: Display
– Setting Up SEASAVE Displays).
See Marking Scans in Section 8: Real-Time Data and Real-Time Control -
Real-Time Data Acquisition to mark the scans during data acquisition.
Note:
The .mrk file has the same
path and file name as the data
file. For example, if the data
file is test1.hex, the .mrk file is
test1.mrk.
Selected variables and number of
decimal points to right of decimal place

list of variables appears; select desired
variables and number of decimal
places to right of decimal point for
each variable, and click OK.
Sequential mark number, system time,
and all selected variables are written to
.mrk file each time Mark Scan is
clicked during data acquisition.
