Files 001-073, 074-100 Readme
CTD casts 001-073 had Beckman/YSI sensor on V4, Seapoing fluorometer on V6
CTD casts 074-100 had Beckman/YSI sensor on V6, Seapoint fluorometer on V4

Merged Upcast & Downcast database csv should not be affected but the individual
CTD stations csv were merged with bottle data in two batches: 001-073, 074-100.
This only affected the fluorometer voltage vs bottle chl-a regression and estimate
calculation.
