外文摘要：Dual water isotopes were investigated to reveal the seasonal distribution of water masses and their impacts on nutrient supply in southern Beibu Gulf. In summer and winter, the South China Sea (SCS) water (61–69%) contributed the most to the seawater in the southern Beibu Gulf, followed by the diluted water (24–34%), and the west-Guangdong coastal current (WGCC) (5–7%) had the minimum contribution. However, the major nutrient source shifted from the diluted water in summer (39–73%) to the SCS water (57–90%) in winter. The WGCC's impact on nutrient loads was relatively small (2–10% in summer, 4–34% in winter). Our results highlight the control of nutrient supply was the SCS water (winter) and diluted water (summer), with limited influence from the WGCC, providing new insights into the impact of water mass transportation and its nutrient supply in the Beibu Gulf. ? 2023 Elsevier Ltd
