 Change history: YYMMDD
   060110: original version prepared from an Excel file of merged CTD, nutrient 
           and SF6 data file, by Terry McKee (PO Dept, WHOI);
           all units information taken from original .xls file;
   060206: added to OCB database by Cyndy Chandler, OCB DMO, (cchandler@whoi.edu)
   070328: dates and position information corrected to match Seabird header records

06 February 2006: Prepared for OCB data system by Terry McKee (PO Dept, WHOI) and Cyndy Chandler, OCB DMO (WHOI).

The SIO_bottle data object was prepared from an Excel file of
merged CTD, nutrient and SF6 data file for the SIO-CTD Rosette on Revelle.
Contact Zanna Chase (zanna@mbari.org) with questions the about the original data.
The Excel file was downloaded in December 2005 from the SOFeX data web site:

merged_SIO_CTD_nut_sf6.xls

Nutrients were run at MBARI on an Alpkem RFA.
Some vials thawed during transit and produced bad numbers; these have been excluded.

Note: Temp is T90 (ITS-90 scale confirmed from .btl file headers);
PO4, Si, NO3 and NO2 are all µM, micromolar

The event number, date, time, latitude
and longitude position information were taken from the *.hdr CTD header (NMEA) records.

SF6 data

SF6 data are from SF6_Revelle_final.xls posted by Kevin Sullivan in October, 2002

SF6_Revelle_final.xls

Questions concerning the SF6 data (October, 2002 revision) should go to Rik Wanninkhof or Kevin Sullivan (kevin.sullivan@noaa.gov).

Additional comments are available in the cruise report by Kevin Sullivan (SOFEX_report-kfsullivan.pdf; converted from the original Word .doc file)

These comments pertain to the original Excel workbook file:

For profile data (in "casts, purge&trap" worksheet):
These analyses, except on station #8, were done via purge and trap with a ~240 ml stripping chamber.
The samples for cast #8 were drawn into glass syringes and the water was equilibrated with added UHP nitrogen. The SF6 in the headspace was measured.

The station, cast, and niskin numbers were recorded by the SF6 analysts along with the SF6 results, which are reported in femtomoles per liter seawater. The hydro files were the source of the rest of the data.

When replicate sample bottles were drawn from the same niskin, the analyses are listed in the order of drawing.
A single open line separates individual casts; double open lines separate the visitations to the two enriched patches.
