D14C measurements were conducted at the NERC Radiocarbon Facility and at NOSAMS. An offset of +6.8 per mil was applied to the NERC data, calculated by the mean difference in measured D14C in 26 replicate samples measured at NOSAMS and at NERC. NOSAMS data are reported for these 26 replicate samples, NERC data are reported for all other samples. d13C data are reported for NOSAMS only. Support for the NERC measurements was provided by NERC grant NE/P019242/1 (TICTOC) with additional support from the NERC Radiocarbon Facility.

Red new version of bottle file from Yvonne Firing on 5/22/19. Minor re-formatting including removing empty CFC columns (data expected, but not included)
Submission note from R Key: I started with the file that Joana uploaded. That file included many "oddities" (such as being sorted by bottle number rather than station) and several parameter name issues. All of those issues have been corrected. Also, I've added the C14 and C13 data from Britain. At some point NOSAMS will have additional values for these 2 parameters. Consequently, I've listed the status as "incomplete" My flags on the carbon isotopes already OK'ed with Joanna Lester.

Changes
-------
* re-sorted the data so that CTDPRS was in increasing pressure order for each cast
* DELC13 flags changed from -999 to 9 for fill value
* NOTE: CTDTMP, CTDSAL, CTDOXY have fill value for flag 2 where the sample is flagged 4/bad

This version has final carbon values, C13/C14 values, a couple of flag fixes
Updated file with all samples
Data are public *except for CFC/SF6 data, which are proprietary to Marie-Jose Messias, Exeter*. A095_740H20180228_hy_no_cfc_values.csv has had CFC columns removed (flags kept to indicate where samples were collected), so that file could be public now. Update will be submitted with final DIC/TAlk and CFC/SF6 data when available.
