摘要

河口洋面在调节陆地污染物向海洋的迁移方面发挥着关键作用。它还对沿岸和河口水域的生态环境产生重大影响。本研究对湛江湾水文和双水同位素进行了月度调查，时间跨度为2019年1月至12月，量化了该区域各种水团的贡献，并探索了锋面强度变化背后的机理。结果表明，盐度锋面在雨季初期开始增强，8 月达到峰值，而在旱季强度普遍较弱。这种季节性变化归因于雨季河水淡水输入量的增加，从旱季的不足 5%增加到雨季的约 15%。重要的是，海洋前沿的加强可能会导致陆上污染物（如营养物质）在海湾内积累，从而使水质恶化。

Driving mechanisms of monthly ocean front variations in a typical mariculture bay: insight from quantitative analysis of dual water isotopes

The ocean front in the estuary plays a key role in regulating the transport of terrestrial pollutants into the ocean. It also significantly impacts the eco-environment of coastal and estuary waters. This study conducted monthly investigations of hydrology and dual water isotopes in Zhanjiang Bay spanning from January to December 2019, quantifying the contributions of various water masses in the region and exploring the mechanisms behind changes in frontal intensity. The results showed that the salinity front began to strengthen in the early rainy season and peaked in August, while its intensity was generally weaker in the dry season. This seasonal variation is attributed to the increased contribution of riverine freshwater input during the rainy season, rising from less than 5 % in the dry season to approximately 15 % in the rainy season. Importantly, the strengthening of the ocean front may lead to the accumulation of land-based pollutants, such as nutrients, within the bay, thereby deteriorating water quality.

期刊介绍： Marine Environmental Research publishes original research papers on chemical, physical, and biological interactions in the oceans and coastal waters. The journal serves as a forum for new information on biology, chemistry, and toxicology and syntheses that advance understanding of marine environmental processes. Submission of multidisciplinary studies is encouraged. Studies that utilize experimental approaches to clarify the roles of anthropogenic and natural causes of changes in marine ecosystems are especially welcome, as are those studies that represent new developments of a theoretical or conceptual aspect of marine science. All papers published in this journal are reviewed by qualified peers prior to acceptance and publication. Examples of topics considered to be appropriate for the journal include, but are not limited to, the following: – The extent, persistence, and consequences of change and the recovery from such change in natural marine systems – The biochemical, physiological, and ecological consequences of contaminants to marine organisms and ecosystems – The biogeochemistry of naturally occurring and anthropogenic substances – Models that describe and predict the above processes – Monitoring studies, to the extent that their results provide new information on functional processes – Methodological papers describing improved quantitative techniques for the marine sciences.
