Important notice (March 1, 2017)

Data delivery system in GDAC (IFREMER) was troubled from Feb. 13 to 28, 2017.
The trouble was that a part of distributed data on B-file (file for biogeochemical parameters) could not get from GDAC.
Please check your downloaded data if you had got B-files during the period from IFREMER GDAC or our ftp site (ftp://ftp2.jamstec.go.jp/pub/argo/ifremer/)and re-download new data if necessary.
The trouble has been fixed on March 1, 2017 and now in normal operation
