方解石吸收稳定同位素和微量金属 四种古生态重要生物的贝壳 将对浮游有孔虫进行研究。 具体目标 包括量化共生体光合作用的影响, 有孔虫呼吸作用对壳内同位素组成的影响, 并确定微量金属的掺入是否 与海水浓度成正比, 温度可影响这种结合。
英文摘要
The uptake of stable isotopes and trace metals into the calcite shells of four paleo-ecologically important species of living planktonic foraminifera will be studied. Specific objectives include quantifying the effects of symbiont photosynthesis and foraminifera respiration on isotopic composition within the shell, and determining whether incorporation of trace metals is proportional to seawater concentrations and to what extent temperature may affect this incorporation.
