Hi Nancy,
Thank you for this information. Your clarification will make the data abundantly 
clear for end users from all backgrounds. I will add this information to 
your accession's documentation.

Best,
Lauren

Hi Lauren,
This is from Nancy. I would just as soon not bother Leslie right now. 
I can answer the questions, but not upgrade the final data files 
submitted, which Leslie has.

2017_Pigments.xlsx file:
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 Phaeopigmen tA 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.
All of the terms you asked for are common in oceanography, and are 
  described in our metadata.
Let me know if you need more.
Nancy

Dear Leslie and Nancy,
My name is Lauren Jackson from NCEI, and I am reviewing your data submission 
titled "Physical (Hydrography), chemical (CTD), and biological (Water Quality) 
processes of the Texas-Louisiana continental shelf, 2017".
I have a quick question about two of your files 2017_Pigments.xlsx and 
2017_YSI6820.xlsx. Can you please provide further clarification on your column 
headings for the list below (for example, will you please spell out the 
abbreviations and clarify what total means). I want to ensure all end users 
of this data will completely understand all of your parameters.

2017_Pigments.xlsx file:
Mean C (ug/L)
Mean P (ug/L)
Total (ug/L)
Mean F
2017_YSI6820.xlsx:
SpC (mS/cm)
ODOsat (%)

You can either provide a listing that explains the above headings or you can 
update the files with more descriptive headings and send them to me via email. 
I will then update your data package with the information you provide. 
Please feel free to let me know if you have any questions.

Best regards,
Lauren
