SOFeX Polar Star Cruise sampling event log

Methods & Sampling

Dataset acquisition description

Methodology: none contributed with data

 Descriptions of SOFeX cruise sampling event types
 
 Brief cruise plan description: 
 The USCGC Polar Star was the third of the three vessels to occupy the SOFeX 
 study area in 2002.  The main focus of the scientific party aboard the Polar 
 Star was to assess how much carbon was removed from the iron fertilized patches.
 A more complete description of the Polar Star cruise is available and a 
 cruise logbook includes daily entries filed by the Chief Scientist aboard each vessel.
 
 A comment on the 'patch_loc' field:
 The SOFeX '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.  For the Polar Star cruise, it appears that only the relative 
 in/out information was recorded.  There were two fertilized patches, one north and  
 one south of the Antarctic Polar Front Zone (APFZ near 61° S) along 170° W.  All of the 
 sampling events for which patch_loc is recorded were conducted south of 61° S, implying 
 the south patch location.

Data Processing Description

Dataset Processing Description

Change history: YYMMDD
    070206: Excel file downloaded from MBARI Polar Star data site;
            original event log contributed by Ken Buesseler (WHOI)
    070208: added to OCB by Cyndy Chandler (cchandler@whoi.edu); 
            changes were made to original data and confirmed by PI
    070427: added some patch_loc data from LVP_pump data file
    070430: added Transect 1 cast events from Transect 1 CTD profile data
 
 Modifications made by OCB DMO to original version of data: 
    position data in event log was compared with ship's position log
    and any missing event log data were taken from ship's position log; 
    See OCB DMO notes file for details.
