 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. 
 The designations SOFeX-N and SOFeX-S are sometimes used to distinguish between 
 two iron enriched patches - one in low silicate waters north of the polar front 
 (SOFEX-N), and the other in high silicate waters south of the polar front 
 (SOFEX-S). All three ships, Melville (MV), Revelle (RR) and Polar Star (PS), 
 worked in SOFEX-S, but only the Revelle and Melville worked in the SOFeX N 
 patch and shuttled between the two patches.
 
 The R/V ROGER REVELLE from Scripps Institution of Oceanography sailed first. 
 The REVELLE team added iron to two areas referred to as 'the North and 
 South patches'. After the iron and an inert chemical tracer (SF6) were added, 
 the REVELLE's primary mission was to map the size and characteristics of 
 the South patch using a SeaSOAR fish towed behind the ship that pumped water 
 up to the ship for sampling and analysis. The REVELLE also collected samples 
 for initial biological shipboard mapping of iron concentrations, nutrients, 
 chlorophyll, and photosynthetic efficiency. A cruise logbook includes daily 
 entries filed by the Chief Scientist aboard each vessel.

Data Processing Description

 Change history: YYMMDD
    051206: original data downloaded from SOFeX data site at MBARI;
    060210: added to OCB database by Cyndy Chandler, OCB DMO, (cchandler@whoi.edu)
    070327: event 200202082228 SIO2 CTD cast changed from station 32 to 31
            per Susan Brown (UH Manoa)
    070328: SIO1 CTD event data replaced by information in CTD NMEA header records
    
 DMO notes: original version prepared by Zanna Chase (zanna@mbari.org) 
    based on activity log sheets and Chief Scientist's cruise notebook
