Pressure (decibar)
This field displays the most recent data from the optional Argonaut pressure sensor, in decibars
(will be blank if the pressure sensor is not installed).
External CTD: Temp, Cond, Press, Sal
These fields display the most recent data from the optional integrated CTD sensor. Temperature
is displayed in °C, conductivity is displayed in Siemens per meter, pressure is displayed in
decibars, and salinity is displayed in ppt. All fields are blank if the sensor is not installed.
Waves: Hsig, Tsig
These fields display the most recent significant wave height (Hsig in cm) and wave peak period
(Tsig in s). All fields are blank if the sensor is not installed.
Graphical display
The graphical display shows a time series plot of the three velocity components. Components are
plotted in white (V1 / Vx / Veast), yellow (V2, Vy, Vnorth), and green (V3, Vz, Vup). The
horizontal and vertical scales of the plot can be changed using the active keys described below.
Active keys
Three active keys may be used during data collection. The first two keys (F3 and F5) affect only
the graphical display and do not alter or interrupt data collection. The third key (Alt+F10) stops
data collection. Pressing the Esc key removes the pop up window if any key is pressed
unintentionally.
F3 - Change time scale: (Multiple-choice)
Pressing the F3 key lets you select the time scale of the velocity sample plot. Time scale options
are: 10, 30, 100, 300, 1000, 3000, and 10000 seconds.
F5 - Change Vel Scale: (Multiple-choice)
Pressing the F5 key lets you select the full scale of the time series plot. Velocity scale options
are: ±10 cm/s, ±20 cm/s, ±50 cm/s, ±100 cm/s, ±200 cm/s, ±300 cm/s, and ±500 cm/s. Note that
this setting does not affect recorded data.
[ALT] F10 - Stop Program: (Yes/No)
To stop data acquisition, you must press the Alt and F10 keys simultaneously. After this is done,
you are presented with a prompt (a Yes/No multiple-choice window) to confirm the intention to
stop the program. Data collection/recording proceeds normally until the confirmation is given.
Upon selecting Yes, the program returns to the setup screen. If the program was run with the
automatic start option (ARGONAUT -g), confirmation after Alt+F10 returns to the DOS prompt.
5.5. Data Recording
Argonaut data are recorded in a standard binary file format; the same format is used whether data
are recorded using the real-time data collection software or on the internal recorder. Within the
standard data file format, there are two options for the format of individual samples: LONG or
SHORT data format. The choice of data format is set using the DataFormat command from the
direct command interface (see the Argonaut Operation Manual). The SHORT format is provided
for autonomous deployments to conserve internal data storage for long deployments. The realtime
data collection always uses the LONG data format.
When data collection is started, the hardware configuration and user operating parameters are
stored in a file header structure. With each sample (using the LONG format), the system stores a
