BCO-DMO Processing Notes
Prepared by WHOI OCB-DMO from original file: FeX2 edited CTD,TM ROS,nuts and C.XLS
Original file was downloaded on 16June2008 from http://www.mbari.org/sofex/IronEx_II.htm

Changes made to original file:
- Extensive editing to remove blank lines, organize data (stations, etc) into rows/columns
- Multiple occurrences of parameter header lines throughout file removed
- Single parameter header line at top retained after reformatting
- Misc comments replicated in cast log removed from file

- Parameter names edited to conform to BCO-DMO convention
- Discrepancy in units for parameters Total_PP and Total_HP
- Units reported as µgC/l in some cases, µM C in others
- This discrepancy still needs to be resolved (BCO-DMO, 22July2009)
- Duplicate parameter names Phaeo changed to Phaeo_a and Phaeo_b

- Station changed to Station_Id as parameter name
- Station_ids using multiple rows combined into one station id
- Spaces replaced with underscores in station_ids
- "#305" is sample number for Transect_thru_hull_#305 in these stations

- date, time, event, cast, lat, lon manually inserted from Cast Log using event in Cast Log
- Original lat/lons, dates, times checked against same data in Cast Log before using
- Found SLIGHT differences between original and cast log
- Used cast log values throughout (appeared to be more reliable/consistent)
- Original event replaced with event from Cast_Log for consistency

- "nd" inserted as no data value in blank cells

Issues/Notes:
TM-Rosette-test: "note NO3 rinse" comment removed

Cochlan (in original event column) - What does Cochlan mean/signify??

Event: 19951473510 - obvious incorrect time but no correction found
Station_Id: TM-Rosette_259 Original Time is 1440, Cast Log time is 1727 (Used Cast Log)
Station_Id: TM-Rosette_314 Original Time is 1402, Cast Log time is 0000
(Used Cast Log - 1402 is closer to on deck time)
