Dataset description

IronExII Event Log

Acquisition description

Comments from original spreadsheet:
event: Any "over the side" activity

SF6 = SF6 concentration in surface waters
CTD_Flag = "X" means cast data is included in the CTD data file
Fe_Flag = "X" means cast data is included in the Fe data file
POC_Flag = "X" means cast data is included in the POC data file

orig_event_number:
* not on lab log
no# on lab log but no # with it
NOSL not on ship's log
NP no SF6 peak detected
no cast #s 235, 386, 387, 388 on lab log

Patch = Refers to sampling in ("I")or out ("O") of the established Iron enriched patch, based on SF6 measurements
Primary Fe "patch" infused on JD 149,150, reinfused on JD 152 and JD 156,157: nominal concentration of 2 nM Fe
Control "patch" (SF6 only) infused on JD 159,160 2nd Fe "patch" infused on JD 160; nominal concentration of 0.4 nM Fe
"I old" refers to sampling in the primary patch after JD 160
".4I" refers to sampling in the 0.4 patch after JD160

BCO-DMO Processing Notes
Generated from original spreadsheet: FeX2 Edited log.xls
Original file was downloaded on 08June2008 from http://www.mbari.org/sofex/IronEx_II.htm

Changes made to original file:
Parameter headers edited to conform to BCO-DMO convention
- Event generated from YearDayTime
- Original event preserved as orig_event_number
- Date reformatted to YYYYMMDD
- Time reformatted to HHMM
- Lat/Lon converted to decimal degrees
- In/Out changed to Patch (In/Out of Patch)
- nd added for no data values and blank fields
