海底地下水排放现已成为全球关注的现象，因为研究表明，它不仅占海洋淡水输入的很大一部分，而且对许多物质的负荷也有重大贡献。目前，在爱尔兰的地下水监测很少在其进入海水的点进行，因此，淡水的体积，以及通过海底和潮间带地下水排放（SiGD）进入爱尔兰沿海沃茨的营养物和污染物的负荷是未知的。SiGD是进入Corrib和Shannon主要西海岸河口之间的爱尔兰沿海沃茨的主要淡水来源。对冬季输往高威湾南部的SiGD的流量进行了计算，结果表明，SiGD的流量相当于R. Corrib的营养负荷可能与R. Corrib该沿海岩溶区包括重要的商业贝类沃茨，可能会受到SiGD的强烈影响。(C)2011爱思唯尔有限公司版权所有。
Submarine Groundwater Discharge is now a phenomenon of global interest, as studies show that it represents both a significant proportion of the fresh water input to the ocean, and a significant contribution to the loads of many substances. At present, little monitoring of groundwater in Ireland is carried out at its point of entry to seawater, and consequently the volumes of fresh water, and the loads of nutrients and contaminants being carried into Irish coastal waters by submarine and intertidal groundwater discharge (SiGD), are unknown. SiGD is the principal source of fresh water entering Irish coastal waters between the major west coast estuaries of the Corrib and the Shannon. Calculations of the volume of submarine SiGD delivered to southern Galway bay in winter indicate it equals 10-25% of the discharge of the R. Corrib, and that its nutrient load may be of the same order of magnitude as that from the R. Corrib. This coastal karst area includes important commercial shellfish waters, which may be strongly impacted by SiGD. (C) 2011 Elsevier Ltd. All rights reserved.
