Underway measurement of Iron (Fe (III))

Methods & Sampling

Dataset acquisition description

 dates:           11 January 2002 to 8 February 2002  (20020111-20020208) 
 location:        N: -54.02746  S: -66.66375  W: -172.2364  E: -169.1244 
 project/cruise:  SOFeX/RR

Contact: Ken Johnson or Zanna Chase, Monterey Bay Aquarium Research Institute (MBARI)

Methodology:

Near-surface (~3-5 m) seawater was collected through an all-teflon pumping system deployed off the back (starboard side).
Flowing seawater was acidified briefly to pH 3.3 before being analyzed for Fe(III) by chemiluminescence flow injection analysis using
preconcentration on an 8-HQ column.

Data Processing Description

Dataset Processing Description

 Change history:
    070607: downloaded original data (Revelle_Fe_underway.xls) from SOFeX project data web site.
            dataset prepared for OCB database by Dave DuBois (OCB DMO, WHOI) 
    080819: added to OCB database by Cyndy Chandler, OCB DMO, (cchandler@whoi.edu)

19 August 2008: Prepared for OCB data system by Cyndy Chandler, OCB DMO (WHOI) from notes contributed by Ken Johnson.

Original Excel file downloaded from MBARI:
copy of original Excel file

The investigator contributed an Excel file
with standard survey times to be used for plotting underway data. The original Excel file is also available as a PDF format file.

OCB DMO and PI notes:

There were two comments embedded in the Excel data file:

 Date       Time	Longitude	Latitude	Iron Fe (III) 
 20020203	053203	-172.0517	-66.12574	0.251420	
 NOTE: UW SAMPLES FROM 47 ON WERE COLLECTED IN REUSED (RINSED) SAMPLE BOTTLES
 
 20020122	221801	-170.1094	-66.40685	0.206346	
 NOTE: discrete#21b-filtered

Plots of selected North Patch data (Iron, SF6, oxygen and fluorometric chlorophyll) showing surface underway
data from the return trip to the North patch Feb 7-8, 2002. These plots were contributed
as a PPT file, and have been converted to a single PDF format file.
