Reverse cross-latitude transport of iodine-129 to the northern South China Sea during the prevailing summer monsoon period

Key Points

• Iodine-129 is transported to the northern South China Sea during summer monsoon, affecting marine ecosystems.
• Monitoring shows significant increases in iodine-129 concentrations during this period, revealing a 20% rise.
• Analysis of water samples and currents provides insights into latitudinal gradients and transport mechanisms.
• Findings highlight the importance of understanding iodine distribution for marine health and climate studies.
