 Descriptions of SOFeX cruise sampling event types
 
 Brief cruise plan description:
 Three ships were involved in the SOFeX experiment. Each ship operated in 
 the study area at a different time to afford the longest observation time.  
 A  cruise logbook includes daily entries filed by the Chief Scientist 
 aboard each vessel.
 
 A comment on the 'patch_loc' field:
 The 'patch_loc' field is usually one of four abbreviation codes indicating the 
 sampling location relative to the 'iron fertilized patches'; N indicates North Patch, 
 S = South Patch, and whether the location is within or outside the patch area or on
 the edge of the patch.

Processing description

Change history: YYMMDD
    070323: original Excel file downloaded from SOFeX data site at MBARI;
            original version (v1.0) prepared by Michael Hiscock (hiscock@duke.edu)
    070329: added to OCB database by Cyndy Chandler, OCB DMO (cchandler@whoi.edu)
            some minor modifications to event type (ev_type) to ensure database
            consistency; only significant change to data during posting was:
            UID_SFX=109 SOFEX02R 026 event_SFX=20020311045 TMR1
            original position was:  lon 171.918 E  and lat 66.322 N (OCB DMO changed 
            both to be negative to reflect West and South); Also note that Polar
            Star event 20020430523, CTD01 test cast, is reported at -172.917 -74.117
            but the CTD data were reported with an Eastern longitude of 172.924.
 
 DMO note:  events are grouped by cruise (e.g. not sorted by time); note that 
    event number comprises a simple Day of Year and not Julian Day (as documented 
    in the original PI note contributed with the data), and that event_SFX
    numbers are not unique, so caution must be used when using event_SFX to
    combine data sets.  There are 40 pairs of duplicate event numbers.
 
 PI notes:  Version 1.0   September 7, 2002
    Event logs for the three ships are compiled in the Melville-format.  
    Event number is YYYYJJJUUUU   Y=year  J=Julian Day, U=UTC.  The event numbers 
    for Jodi Brewster's SCUFAs and the Melville SF6 data have been included.   
    A notable addition is the "Time since Fertilization" column for the South 
    patch and North Patch.  I used the midpoint of the first fertilzation of 
    each patch as time zero.  North patch 20020131415.  South patch 20020250430.
    I would like to keep this event log as complete and accurate as possible.  
    Please email Michael Hiscock (hiscock@duke.edu) with any additions or corrections.
