Short-term variation of triple oxygen isotopes and gross oxygen production in the Sagami Bay, central Japan
Short-term variation triple oxygen isotopes gross oxygen production Sagami Bay central Japan
2006/5/4
We studied diurnal and daily variations in triple oxygen isotopes in the euphotic zone of the Sagami Bay during summer 2003 and 2004. There were sharp changes in physical processes, driven by changes ...
