Comment:
# 91 CTD stations with 24 place Rosette. Region: tropical ocean of the SE-American oxygen minimum zone.
# Chief Scientist - L. Stramma
# O2 (F. Malien). Status - final.
# Nutrients (F. Malien). Status-final measured on-board. Adjusted to RMNS (batch AZ Aoyama MRI Japan)‚Ä NO3 - 1.0066: PO4 - 0.9937: Si - 1.0065
# Final QC by T. Tanhua 2010.06.10.
# 2nd QC (i.e. comparion to GLODAP data base essentially P19 from 1993 and P21 from 1994):
# Oxygen no significant offset Phosphate: M77/4 4% high Nitrate: No offset" Silicate: no offset
# N2O (A.Kock). Status-final. Mean value of triplicates.
# Delta 15N values for nitrate nitrite and the sum of the two (in permille). Zhenya Ryabenko
