Later in the cruise a SBE911 was used. Oxygen:Dissolved, Conductivity and Fluorescence:URU:Wetlabs data are nominal and unedited except that some records were removed in editing temperature and salinity. No salinity and dissolved oxygen sampling was done while SBE0334 was in use. Extracted chlorophyll was sampled at the surface and fluorescence compared reasonably well with ratio FL/CHL ranging from 0.8 to 2.2. In a typical pattern for these fluorometers, the higher ratios come from cases where CHL<1.5ug/L.
