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.

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:
