“…Despite of the anthropogenic effects in the Weizhou Island, W. Jiang et al. (2022) also established a robust correlation between sea surface winds and the temporal variability of Porites coral V/Ca ratios, indicating significant potential for capturing historical shifts in tropical cyclones (TC). However, previous research has focused on estuarine areas (e.g., Chen et al., 2015; Guzman & Jarvis, 1996; Nguyen et al., 2013; Saha, Webb, Christy, & Zhao, 2019; Tanaka et al., 2013) or over a short period (e.g., W. Jiang et al., 2022), thus potentially limiting the interpretation of this proxy.…”

“…In offshore environments free from anthropogenic influences, coral V may serve as an indicator of variations in the runoff associated with rainfall and the upwelling controlled by East Asian Summer Monsoon, based on the decadal variations of V from a 159 years coral record (1853-2011) (Chen et al, 2015).

In recent decades, vanadium (V) levels in the environment have dramatically increased and will continue to rise alarmingly in the future. Conventional methods for assessing oceanic V typically only involved the collection of seawater and sediments, which significantly limited our understanding of the dynamics of oceanic V and its relationship to environment and climate. Here, the interannual temporal variations in surface seawater V levels in the northern South China Sea, were reconstructed utilizing a 137‐year record of V/Ca ratios from Porites lutea coral from Xiaodonghai Bay off Sanya. We observed that anthropogenic activities had a limited impact on the V levels of surface seawater in the study area, whereas V variability exhibited significant disparities across different time periods. Precipitation‐related submarine groundwater discharge (SGD) recharge was the primary driver of V variation prior to 1990, with tropical cyclones (TCs) playing a detectable role in total precipitation during this period. Conversely, changes in surface seawater V levels after 1990 were predominantly linked to increasingly intense upwelling driven by summer winds. The recharge processes in unconfined groundwater systems within the study area might generate favorable oxic and alkaline conditions, which facilitated mineral dissolution and/or desorption reactions that elevated V concentrations along the groundwater flow path, which were recorded in coral skeletal V/Ca ratios. This study confirmed the seawater V was dominated by SGD and upwelling near Sanya, providing essential evidence for comprehending the geochemical behavior of V and the impact of ocean‐atmospheric climate interactions on long‐term variations in seawater V levels.
