A16_2003_2005_undecimated_CTD.jos If your copy of JOA cannot read the binary version of this file because it is too large, if you start JOA and use the "Open" command in the JOA File menu to open the A16_2003_2005_undecimated_CTD.jos text data file, and just click "OK" (i.e. use the defaults) in the Spreadsheet import dialog box, JOA should open the data file (if your computer has sufficient RAM).
