Subject: North Pacific Argo float data: An Important Notice


Dear "North Pacific Argo float data set" users,

In this March, I noticed you that some floats can have serious offset error.
Last month (Oct. 11), Argo Project Office (http://www-argo.ucsd.edu/)
made an additional announcement on this issue.  They announced that
part of the data that can be corrected exactly using automated procedures
restarted to be distributed after correction.

Therefore, from now on, the monthly data compiled by me can
contain data from the "problematic" floats, but they are all corrected
and can be used safely.

The website for the dataset:

regards,
Eitarou

> Dear "North Pacific Argo float data set" users,

> In mid-Feb, Argo Project Office (http://www-argo.ucsd.edu/) announced
> that pressure values measured by some floats can have serious offset error.
> The relevant floats are 287 SOLO-type floats (including those already stopped 
> their operation) that are equipped with FSI CTD sensor and owned by WHOI.
> Although most of these floats were deployed in the Atlantic, 16 of them were 
> deployed in the Pacific (WMO IDs of all 287 floats are listed in the attached
> file "bad_fsi_list.txt").  Argo Project Office advises not to use the data 
> from these floats until the problem is resolved.

> In response to this problem, I checked all the data from Jan. 2001 through
> Dec. 2006 that I have made, and found 17 profiles from 2 relevant floats
> (WMO 3900151 and 3900152) are included in my data (see attached
> "okadata_bad_fsi_list.txt" for details).
> 
> Since it's hard to delete all these bad profiles from the already released data 
> (for both me and the users), I'm not going to change the data in responce to

> from the 2 floats (WMO 3900151 and 3900152) when you analyze the data
> in 2004 and 2005.  The data made from now will not include profiles 
> from the relevant floats.
> 
> I apologize for the inconvenience and the late notice.
