 lat               latitude (negative = south)                  decimal degrees

 fluor_CDOM        dissolved organic matter stimulated by UV
                     (355 nm) laser.  Emission is measured at
                     450 nm and normalized to the water Raman
                     emission at 404 nm.  This is a  relative
                     measurement. 
 fluor_PUB         phycoerythrin-phycouribilin complex stim-
                     ulated by green (532 nm) laser.  Emission
                     is measured at 570 nm and normalized to
                     the water Raman signal at 650 nm.  This
                     is a relative measurement.
 fluor_PEB         phycoerythrin fluorescence stimulated by
                     green (532 nm) laser.  Emission is measur-
                     ed at 585 nm and normalized to the water 
                     Raman signal at 650 nm.  This is a rela-
                     tive measurement.
 chl              chlorophyll concentration converted from      micrograms/liter
                     chlorophyll fluorescence.  The chloro-
                     phyll fluorescence was stimulated with a
                     532 nm laser and emission measured at
                     685 nm.  The emission was normalized to
                     the water Raman signal at 650 nm and the
                     relative measurement converted to chloro-
                     phyll concentration. This is a "good faith"
                     final calibration.
