ARTOA 4 user manual

Note: This version of ARTOA4 was developed under Matlab 2020a. It seems to work under 2020b. However, it does not work under 2021b (Temperature und Pressure windows show no data).

Known Issues

1. When having deleted all tracks in the trajectory window, renewed tracking throws an error message. Workaround: Close the trajectory window and retrack from the main window

Time Of Arrival window

Left hand information panels

• Soundsource colors
• TOA histogram
• Adjust colormap boundaries
• Duplicates

Central TOA display

• Scatterplot of TOAs. In grey scale (controlled by "Adjust colormap boundaries") for unassigned TOAs, in color (according to "soundsource colors" for TOAs assigned to a certain sound source.
• Message date = ......

Right hand control buttons

• Select

  • Polygon

    Allows defining a ploygon by consecutive left-clicks and its closure by a right cklick. Minimum number of corners is 4. All TOA points therein are selected.

  • Rectangle by date range

    Defines a rectangular selection box limited by Start and End dates in x, and full TOA range in y. All TOA points therein are selected. Start and End dates are entered via popup and are indicated by vertical gray lines.

  • Points

  • Drop

• SoundSource
  • Apply
  • Apply All Visible
  • Withdraw
  • Withdraw All Visible
  • Rempap
• Shift

  • Shift selected

    Shifts all selected TOAs (vertically) by the amount of seconds entered. Used, e.g., to correct for undocumented jumps in the floats clock, resulting in jumps in the TOA.

  • Reset selected

  • Reset all

ARTOA4 memory data format specification

The specification defines the structure of the MATLAB variables that are used by ARTOA3. The following formats are available:

1. RFB (.rfb) and SoundSource (.soso) files
2. Trajectory
3. artoaGui
4. artoaWorkspace
5. artoaDataInput
6. toaData

ARTOA4 Algorithms

The documentation of the algorithms can be found in the following documents:

1. Offset calculations
2. Satfix Toa Calculation
3. Soundspeed Selection

ARGO trajectory export

artoa4 provides an export to netCDF function. This function is available through the File -> Save -> Argo trajectory file menu entry.

This will generate a netCDF file based on the argo specification.
