Oxygen isotope ratio (δ18O) by mass spectrometry
1. Seawater samples were collected in 12L Niskin bottles mounted on the CTD-rosettesystem and then transferred into 20 ml glass vials for delta18O analysis.
2. Samples were stored in refrigerator (~5degC).
3. Samples were analyzed by Dr. Naoyuki Kurita at JAMSTEC.
4. Data were reported as a permil deviation of oxygen isotope ratio of the sample fromthat of international standard seawater (VSMOW):
delta18O = {(H218O/H216O)sample-(H218O/H216O)VSMOW}/(H218O/H216O)VSMOW * 1000 [permil].
