Mean C (ug/L); This is the mean of Chl A and Chl B replicates 
	(Mean Chlorophyll A); the equation is in the spreadsheet
Mean P (ug/L): This is the mean of Phaeopigment A and 
	Phaeopigment B replicates (Mean Phaeopigment); the 
	equation is in the spreadsheet
Total (ug/L): This is the sum of Chl A and Phaeo A for Total A. 
	Total B is the sum of Chl B and Phaeo B. Total is the mean 
	of Total A and Total B; the equations are in the spreadsheet
Mean F: Fo/Fa A is the ratio of the F value for replicate A from 
	the fluorometer before acidification divided by the F value for 
	replicate A after acidification. Same for Replicate B (Fo/Fa B). 
	Mean F is the average of Fo/Fa A and Fo/Fa B. The equations 
	are in the spreadsheet

2017_YSI6820.xlsx:

SpC (mS/cm) This is specific conductance (or conductivity) of a 
	water sample. The units are micro Siemens per centimeter. 
	Used to calculate salinity. This is the "C" in "CTD."
ODOsat (%) This is the percent saturation of dissolved oxygen 
	in an aqueous solution at the given salinity and temperature.

The units for both come directly from the instrument.
