“…The northern SCS is influenced by monsoons, particularly the EAWM, which plays an important role in ocean and climate variability on seasonal to interannual time scales (e.g., Jiang et al., 2023; Murty et al., 2017; Ramos et al., 2020). During weak EAWM periods, warmer and wetter conditions occur, leading to relatively low SSS in the SCS.…”

The Kuroshio intrusion (KI) is a northwestward‐flowing branch of the Kuroshio Current, which enters the South China Sea (SCS) and regulates its temperature, salinity, and water mass exchanges. However, limited direct observations hinder our understanding of KI's mechanisms and responses to climate change. Here, we present a 60‐year bi‐monthly resolved coral oxygen isotope (δ18Oc) record from Dongsha Atoll, the northern SCS. The dry‐season (December–March) δ18Oc record reveals interannual to decadal variabilities of the KI. The impact of the East Asian winter monsoon (EAWM) on Dongsha δ18Oc was more pronounced during the 1970s and 1980s and after the early 2000s, while the influence of the El Niño‐Southern Oscillation (ENSO) on Dongsha δ18Oc was higher between the 1980s and 1990s. The Pacific Decadal Oscillation (PDO) may have a relatively minor effect on KI strength or may indirectly modulate KI strength through its influence on ENSO activities. Our Dongsha δ18Oc record highlight the importance of the EAWM, ENSO, and PDO in predicting future KI changes.

“…Li et al, 2020;Linsley et al, 2019;Yu, 2012;Yu et al, 2012). Although previous studies have indicated that SST can affect the change of coral δ 13 C by influencing the photosynthetic intensity of zooxanthellae, no correlation was found between SST and skeleton δ 13 C values in a temperature-controlled tank experiment conducted over 142 days at five temperature settings between 21°C and 29°C (Suzuki et al, 2005;Wang et al, 2021;Xu et al, 2018). The seasonal variation patterns of coral-derived Sr/Ca-SST during 5.6-3.6 ka BP and modern instrumental SST in the eastern Hainan Island were the highest in July and the lowest in January, thus, lagging the seasonal variation patterns of carbon isotopes (Figure 2d).…”

Coral skeleton δ13C is a routinely measured indicator in modern insolation change research, but the knowledge of environmental and climatic signals recorded in its seasonality during geological time is sparse. In this study, we present eight Porites coral δ13C records from the mid‐late Holocene to the present from the northern South China Sea (NSCS). Compared with the main control factors for modern δ13C changes, coral δ13C seasonality in the NSCS since the mid‐Holocene shows a long‐term decreasing trend, which is consistent with the change trend as orbital‐induced (precession) insolation seasonal amplitude. By excluding other influencing factors, we speculate that the stronger coral δ13C seasonality (18.8%) over the mid‐Holocene than modern period is attributable to the metabolic effect, which predicts the stronger coral δ13C seasonality under stronger insolation seasonality. Our study has implications for coral δ13C seasonality as a potential indicator to record past insolation information under different climatic backgrounds.
