Generated from original file: FeX 1 CTD,Nuts,SF6.xls
Original file was downloaded on 16June2008 from http://www.mbari.org/sofex/IronEx_I.htm

Changes made to original file:
- Extensive editing to remove blank lines, organize data (stations, etc) into rows/columns
- date, time, event, lat, lon, depth manually inserted from Station list using event
- “nd” inserted as no data value in blank cells
- Parameter names edited to conform to BCO-DMO convention
