中文摘要：

近海海底第四纪淡水资源主要赋存在相对比较封闭的古河道砂体地层环境中,埋藏古河道分布是海底淡水资源的研究重点。介绍了我国舟山北部海域海底淡水资源初步研究成果,在综合前人研究成果的基础上,指出了海底淡水资源调查研究中存在的问题,对未来工作提出了展望。

英文摘要：

Submarine freshwater, as a kind of potential water resources, are mainly preserved in the relatively closed ancient sandy channel fillings. Therefore, paleochannel is regarded as the main target for submarine freshwater exploration. In this paper,we provided an overview of the distribution pattern of paleochannels and the conditions for submarine freshwater accumulation in the offshore area to the north of the Zhoushan Islands. Technical problems and future exploration strategies were also discussed.
