中文摘要
这项SGER奖将支持对从赤道太平洋和百慕大近海的沉积物陷阱中收集的浮游有孔虫个体标本的稳定同位素分析。其目的是确定同位素比率是否取决于在受控实验室实验中观察到的环境水的碱度。如果碱度效应存在并且可以量化,发表的基于有孔虫同位素数据的海洋生产、环流和二氧化碳变化的解释将需要修订。
英文摘要
This SGER award will support analysis of stable isotopes in individual specimens of planktic foraminifera collected in sediment traps from the equatorial Pacific and off Bermuda. The objective is to determine whether isotopic ratios are dependent upon ambient-water alkalinity as observed in controlled laboratory experiments. If an alkalinity effect exists and can be quantified, published interpretations of changes in ocean production, circulation, and pCO2 based upon foraminiferal isotope data will require revision.
