摘　　要：大洋表层海水氧稳定同位素比率(δ^(18)O)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δ^(18)O研究取得了重要进展,其主要体现在δ^(18)O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δ^(18)O时空范围深入认知的不足。本文对大洋表层海水δ^(18)O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。Stable oxygen isotope ratio(δ^(18)O)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 onδ^(18)O in surface seawater has progressed markedly,yielding mainly improved knowledge of theδ^(18)O distribution and source attribution.However,because of constraints on the range of oceanographic surveys,the spatio-temporal variations of oceanicδ^(18)O remain incompletely characterized.In this study,the current research methods and recent progress pertaining toδ^(18)O in ocean surface seawater were summarized,providing a reference for further research on oxygen stable isotope ratios in ocean surface seawater.
