   dates:           January 08, 1995 to January 31, 1995
   location:        N: 22.4835  S: 9.9986  W: 57.299  E: 68.7499

 Notes
      1. Iron (Fe) and Aluminum (Al) concentrations are in nmoles/liter
      2. The filter column denotes whether or not the sample was filtered,
         and the filter size used (0 = not filtered; 0.2 = sample passed
         through 0.2 micron filter and 5 = sample passed through a 5 micron
         filter).
