Description

SO-GasEx Final DIC and TA data from hydrocasts

Methods & Sampling

See: SO-GasEx cruise report, Section 5.7.3 ppgs 46-47

Data Processing Description

Comments from original text file - DIC_TA_hydrocast_readme.txt
Notes by BH, 18 June 2009

DIC, TA data provided by C. Sabine and colleagues at PMEL.

Data provided 29 April by Sabine supercedes all previous versions, and was current as of this writing.

Current data is included in file 'DIC_TA_final_to_BH2.xlsx'

Some earlier versions had improperly applied calibrations.
This was detected by R. Wanninkhof in April of 2009 and subsequently corrected by Sabine.

Wanninkhof has expressed concern over the trend of decreasing surface TA.
No analytical problem explaining this trend has been found.

BCO-DMO Processing Notes
- Generated from original file DIC_TA_final_to_BH2.xlsx

BCO-DMO Edits
- event, station, date, time, lon, lat inserted from CTD headers file
- '-999' (No data flag in original) changed to 'nd'
- decimal places padded to 1 or 2 places as appropriate for consistency
- parameter names modified to conform to BCO-DMO convention
