Hi Melissa,  I am not sure how these values were included in the
submittal, but the oxygen values including File 5 and thereafter are all
erroneous and should have been excluded.  We were trying out a new O2
sensor on this cruise and it failed.  Those DO values should be removed
or replaced with an error flag.
