Isotope and faunal abundance and TOC data from eastern Arabian sea during last 25 kiloyear by Majumder et al., 2022

We present multiproxy data spanning between ~25000 and 3500 calibrated years before the present (cal yr BP) from the eastern Arabian sea (EAS). This is possibly the first record of stable isotope record in pteropods from the EAS. Based on this dataset, we found that the Indian summer monsoon (ISM) was weak during the Last Glacial Maximum (LGM). Moreover, upwelling intensity was high during the early Holocene, which was followed by a significant weakening of ISM during the 4.2 ka event.我们报道了来自阿拉伯海东海域（EAS）的、时间跨度约为距今25000至3500校正年（cal yr BP）的多代用指标数据。该数据集可能是阿拉伯海东海域翼足类稳定同位素记录的首份相关记录。基于此数据集，我们发现末次冰盛期（LGM）期间印度夏季风（ISM）较弱。此外，早全新世时期上升流强度较高，随后在4.2千年事件期间印度夏季风出现显著减弱。
