摘要：

大洋表层海水氧稳定同位素比率(δ18O)能够准确指示多种海洋循环过程, 也可以用来重建古气候变化。随着近几十年采样范围的扩大和分析技术的提高, 大洋表层海水δ18O研究取得了重要进展, 其主要体现在δ18O的时空分布特征及归因等研究方向。但是, 受到海洋调查范围的限制, 现在仍存在对δ18O时空范围深入认知的不足。本文对大洋表层海水δ18O的相关研究方法和研究进展进行了梳理和归纳, 以期为未来的深入研究提供参考。

Abstract:

Stable oxygen isotope ratio (δ18O) in ocean surface seawater is an accurate indicator of oceanic circulations. It can also be used to reconstruct paleoclimates. With the recent expansion of the sampling range and improvement in analytical techniques, research on δ18O in surface seawater has progressed markedly, yielding mainly improved knowledge of the δ18O distribution and source attribution. However, because of constraints on the range of oceanographic surveys, the spatio-temporal variations of oceanic δ18O remain incompletely characterized. In this study, the current research methods and recent progress pertaining to δ18O in ocean surface seawater were summarized, providing a reference for further research on oxygen stable isotope ratios in ocean surface seawater.

Key words: stable oxygen isotope ratio, salinity, ocean surface seawater
