Seasonal variations in the oxygen-18/oxygen-16 ratio of calcite shells of living planktonic foraminifera in the Sargasso Sea off Bermuda are a direct function of surface water temperature. Seasonal occurrence as well as depth habitat are determining factors in the oxygen isotopic composition of planktonic foraminifera. These relationships may be used to determine the seasonal temperature contrast of oceans in the past.
马尾藻海生活的浮游有孔虫碳酸钙壳的氧-18/氧-16 比值的季节性变化是表层海水温度的直接函数。季节性出现以及深度栖息地是浮游有孔虫氧同位素组成的决定因素。这些关系可用于确定过去海洋的季节性温度变化。
