Description

IronExII Underway CO2 Data

Methods & Sampling

Dataset acquisition description

IronEx II CO2 data
Continuous underway sampling from JD 147 to JD 167

Calculated TCO2 data for every pCO2 point assuming a constant total alkalinity (+/- 5 umol kg-1).

The precision for pCO2 is +/- 12 ppm and the precision for TCO2 is about +/- 5 umol kg-1

BCO-DMO Processing Notes
Prepared by WHOI OCB-DMO from original file: FeX2 edited CO2.xls
Original file was downloaded on 16June2008 from http://www.mbari.org/sofex/IronEx_II.htm

Changes made to original file:
- Parameter headers edited to conform to BCO-DMO convention
- Date, time generated from yrday and hr_decmin
- Date formatted as YYYYMMDD
- Time formatted as HHMM
- Decimal places padded to 1,2 places as appropriate for consistency
- "nd" added for no data values and blank fields
