dates: 12 February 2002 to 20 February 2002 (20020212-20020220) location: N: -65.854 S: -74.120 W: 172.924 E: -172.315 project/cruise: SOFeX/USCGC Polar Star (WAGB-10) cruise: PS02 Methodology: data were collected with SeaBird 911 CTD profiler
Change history: YYMMDD 060110: original version prepared from Scripps standard CTD (SIO CTD) casts 060119: added to OCB database by Cyndy Chandler, OCB DMO, (cchandler@whoi.edu) 070327: dates and position information corrected to match Seabird header records. Methodology
10 January 2006: Prepared for OCB data system by Terry McKee (PO Dept, WHOI) and Cyndy Chandler, OCB DMO (WHOI).
Data were processed using the standard set of Seabird utilities,
to generate final 1-decibar pressure sorted downtrace files for all CTD casts.
All final processed *.asc CTD files were downloaded by the OCB DMO
in December 2005 from the SOFeX web site:
http://www.mbari.org/SOFeX/Revelle_Data/Revelle_Station_Data/Revelle_SIO_CTD_data.htm
The event number, date, time, latitude
and longitude position information were taken from the *.hdr CTD header files. Dates and positions as initially
entered in the database were incorrect. This information was corrected in the 27 March 2007 version of the database.
Final CTD station header record:
SIO-CTD station 2
Final CTD station configuration (con report) files were not provided with .asc files.
Also, note there is no data file for station 31.
PI note: the following SIO CTD casts from Revelle have bad oxygen data. Please consult this list to avoid using bad data.
