In this paper, we use planktic foraminifera and mixed-layer species from cores SK-240/327, SK-243/I- and ABP-25/03, northeastern Arabian Sea to investigate monsoon wind variability. Planktic foraminifera include Globigerina bulloides, a monsoon proxy and mixed-layer species Globigerinoides ruber, Gs. sacculifer, Gs. obliquus and Gs. extremus from cores SK-240/327, SK-243/I-1 and ABP-25/03 encompassing last ~11 calibrated kilo years before the Present (~11 cal kyr BP). The population abundances of Globigerina bulloides and mixed-layer species were compared with published Globigerina bulloides percentages from the western Arabian Sea Ocean Drilling Program Holes 723A, 724B and 727B, and eastern Arabian Sea core ABP-25, 02 to understand variations in Indian monsoon winds during the Holocene. In the eastern Arabian Sea, upwelling induced productivity was higher during 10–6.5 cal kyr BP which decreased during 6.5–3 cal kyr BP. In the northwestern Arabian Sea, we observe a similar scenario but not every site captured this change owing to spatial diverseness in monsoon wind stress. The productivity increased since 3 cal kyr BP due to intense summer monsoon winds in the northeastern Arabian Sea, whereas productivity began to increase at ~1.5 cal kyr BP in the northwestern Arabian Sea. The upwelling intensity shows large spatial and temporal variations in the eastern and western Arabian Sea, indicating varying monsoon wind strength across the Arabian Sea during the Holocene. The spectral analysis performed on Globigerina bulloides shows cyclicity which is associated with solar variability during the past 11 kyr record in the northeastern Arabian Sea.

在本文中，我们使用来自阿拉伯海东北部 SK-240/327、SK-243/I- 和 ABP-25/03 核心的浮游有孔虫和混合层物种来研究季风风变率。浮游有孔虫包括Globigerina bulloides、季风代理和混合层种Globigerinoides ruber、Gs。sacculifer，Gs。斜线和Gs。extremus从芯SK-240/327 SK-243 / I-1和ABP-25/03现状（〜11卡KYR BP）之前围绕最后〜11公斤校准年。Globigerina billoides和混合层种的种群丰度与已发表的Globigerina bulloides进行了比较来自阿拉伯海西部海洋钻探计划 723A、724B 和 727B 孔以及阿拉伯海东部核心 ABP-25, 02 的百分比，以了解全新世期间印度季风的变化。在阿拉伯海东部，上升流诱导的生产力在 10-6.5 cal kyr BP 期间较高，在 6.5-3 cal kyr BP 期间下降。在阿拉伯海西北部，我们观察到类似的情况，但由于季风风应力的空间多样性，并非每个站点都能捕捉到这种变化。由于阿拉伯海东北部强烈的夏季季风，生产力从 3 cal kyr BP 开始增加，而阿拉伯海西北部的生产力在 ~1.5 cal kyr BP 开始增加。上升流强度在阿拉伯海东部和西部表现出较大的时空变化，表明在全新世期间横跨阿拉伯海的不同季风风力强度。进行的光谱分析在阿拉伯海东北部过去的 11 kyr 记录中，Globigerina Bulloides显示出与太阳变化有关的周期性。
