    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.

1b:T742,Before he passed away in 1993, John Martin suggested that an increase in the flow of iron-rich dust to the ocean causes phytoplankton (single celled algae) to grow. The increased photosynthesis removes carbon dioxide from surface waters as the algae create biomass. This carbon dioxide is replaced by carbon dioxide gas that flows into the sea from the atmosphere. Reduced carbon dioxide in the atmosphere cools the planet (CO2 is a greenhouse gas that warms the earth). The results of this work, funded by the National Science Foundation, the Department of Energy, and the US Coast Guard, will be a much better understanding of how biological processes may regulate climate. (see Related Info: Fe cycle) A direct test of the 'Martin Hypothesis' that trace concentrations of Fe are responsible for phytoplankton's ability to grow by direct experimental addition of Fe to the surface waters. Consequently the distribution of bioavailable Fe in the surface waters determines large geographical areas primary production and the following flux of fixed organic matter to the deep sea. The aim of the SOFeX project is to investigate the effects of iron fertilization on the productivity of the Southern Ocean. The results of this work will contribute significantly to our understanding of important biogeochemical processes which bear directly on the global carbon cycle, atmospheric carbon dioxide concentration, and climate control. The SOFeX-N and SOFeX-S designations 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.6:["$","$L19",null,{"dataset":{"_id":"2820","description":"
