Lines 52+ include the actual spectral measurements.  The first field on each line is the wavelength 
(in nanometers), and subsequent fields represent each individual measurement at that wavelength.

As described elsewhere (see link to "Brief description of spectroradiometry methods") a series of 
multiple spectra were measured both above and below the surface of the water, with calibration spectra 
acquired before and after each group.  The "Replication" field (line 04 in the above list) provides 
the definitive explanation of which type of observation a given spectrum represents.  However, the 
general pattern is as follows:
