In regards to a couple of errors in station locations in the sum file
for AR24, expocode 316N147_2, Matthew and I made the following changes
on Friday, 8/22/08.
Station: 66
Cast: 1
Time: 09:32
Error: Longitude read: 63 33.92 W
Change: The "63" was changed to "36"
Station: 139
Cast: 1
Time: 20:44
Error: Lattitude read: 55 21.33 N
Change: The "55" was changed to "53"
The CTD oxygen of station No.1 should be changed all to -9.00, as we do not have flags for it anymore, otherwise they would make no sense. Could you change all ALKALI and TCARBN flags were no data was measured from "1" to "9". In the following instances the flag "4" should be changed to "5": sta-cast-sample
11-1-18 ALKALI
16-1-23 TCARBN
16-1-4 TCARBN
16-1-3 TCARBN
28-1-3 TCARBN
30-1-1 TCARBN
47-1-18 ALKALI
47-1-12 ALKALI
49-1-16 TCARBN
51-1-8 ALKALI
51-1-1 TCARBN
71-1-7 TCARBN
74-1-6 TCARBN
97-1-21 ALKALI - also look at the nutrients values, they all should be -9.00
97-1-20 ALKALI
107-1-4 TCARBN
118-1-18 TCARBN
118-1-3 ALKALI
120-1-24 TCARBN
120-1-21 ALKALI
123-1-7 ALKALI
After recommendation from A. Kozyr to edit specific flags for alkalinity and carbon parameters, a new file was sent by Kozyr containing these corrected flags. This new bottle file was checked then used to generate new exchange and netcdf files.
New files were tested with JOA and placed online. Old files were renamed and moved to the original directory.
As per Alex Kozyr and Jim Swift, I have removed the Q1 flags associated with CTD salinity and oxygen. Previously, these bytes were set to "1&" with no DQE information available or pending. Asterisks were also removed from the appropriate headers. All files were regenerated, format tested and placed online.
As per Alex Kozyr's inquiry regarding the the Q1 flags for CTD salinity and oxygen (they were both set to "1" in the bottle file), I have reformatted the bottle file at Jim Swift's request.
-Removed the Q1 bytes for CTD salinity and oxygen. Removed the asterisks under the headers corresponding to these values.
-Reran wocecvt with no errors
-Added name/date stamp.
-Regenerated exchange, netCDF and inventory files with no errors produced.
-loaded files into JOA with no errors.
-replaced all current files, moved old files to original directory.
-RCS'd this action.
Bottle file contains all nutrients in UMOL/L and O2 in ML/L. We've never heard from Mike McCartney on any questions regarding the files and Ruth Curry was the one who offered help on reformatting although it wasn't her cruise.
I recall just using a piece of code from Sarilee for converting CTD oxygens, but is there something for converting bottle oxygens too? and what should I do about the nutrient units? It converted to exchange with the current precision and units, should I put up what we have right now?
I have concatenated and formatted the bottle file for this cruise. File was format checked, units for oxygen and nutrients were converted and exchange, inventory and netcdf files were created.
files were checked with JOA and placed online. Web page files were updated. Notes on formatting were sent to Jerry Kappa. NOTE no documentation file has yet been received for this cruise.
After consultation with ODF (Kristin Sanborn) the units of the bottle file were converted using cvuwoce, a program from Sarilee Anderson. All units were converted to WOCE standard input file was ar24_ahy.txt output file was named ar24_ahy_newunits.txt.
-Ran wocecvt on new file with no errors.
-Added new name/date stamp and copied file to parent directory renamed as ar24_ahy.txt.
-This file was used to regenerate all exchange and netCDF files.
-Checked files with JOA.
-All online files were replaced.
-Sent notes to Jerry and RCS'd the action.
This is an internal report and should not be published.

It was brought to our attention that the bottle file for this cruise was never completely reformatted. This was because we never heard from McCartney the Chief Scientist. However we did recieve directions on reformatting from Ruth Curry for this bottle file. McCartney was supposed to follow up. This has not happened and neither Curry nor McCartney have sent a doc file as of this date. I have reformatted the bottle file according to Curry's instructions.
**NOTE** All values for oxygen are in ML/L and all values for nutrients are in UMOL/L at this time. No conversions have been performed during reformatting.
-Concatenated all 3 ".sea" files together. (s1t60.sea, s61t131.sea, s131t190.sea) new file called ar24_allstns.sea which was copied to ar24_ahy.txt.
-Added WHF to bottle file numbers for stations 1-60 to match all other stations' bottle file numbers.
-Realigned the SILCAT data column.
-Changed all parameter units to uppercase.
-Changed expocode from 31KN47 to 316N147_2 to match sumfile.
-Added name/date stamp.
-Ran wocecvt with no errors.
-Created exchange and netCDF files and checked files in JOA. No apparent errors were produced.
-Created bottle file inventory file with no apparent errors.
-placed all new files on line and regenerated web pages.
As per email from Raymond Pollard an error in the summary file longitude for the BE code of station 141 has been corrected. Minutes were changed from 19 to 15. This error was also corrected in CTD exchange file for station 141.
The NetCDF file for the CTD has not been remade at this time.
Current online index.htm page has also been updated to reflect recent changes in all files.
BOT in multple files. CTD exchg made. Still no DOC from Curry. WOCE frmt all files. Create BOT exchg. Write Curry for DOC.
CTD has been converted to exchange using the new code and put online.
Sumfile was missing WOCE SECT names. It was filled in with AR24. Extra space in header was removed. Sumfile now passes whpo format checks.
I asked Mke Mccartney what, if any data were taken on AR24 other than CTDO data. He said that no tracer data were collected on either of these repeat cruises, and that nutrients were collected only on the first of them.
Yes. We consider these to be in the public domain now.
Take the data from the subpolar ACCE site.
I have added Mike McCartney's Knorr cruise to the AR24's.
Expocode is 316N147_2. Dates are (from the sum file) Nov 2 - Dec 3, 1996.
Chi Sci was Mike McCartney of WHOI. Currently we just have a
sumfile that is being passed off to Sarilee for reformatting. I have
requested the bottle and ctd data from Ruth Curry as per Lynne's request.
