表层水 [海洋] surface water
superficial water
- 而在土壤表层水盐变化规律这方面,仍存在研究空间。
However, there exists an amount of space on the study of soil surface variation. - 南极海域夏季表层水盐度的分布呈现不规则的空间分布,盐度值或高或低的块状分布。
The sea surface salinity shows an irregular spatial patch distribution with higher or lower value. - 通过表层水与底层水中有机氯农药的含量对比,可以发现,大部分采样点的底层水中有机氯农药的浓度要高于表层水,说明底层水中的有机氯农药主要来源于沉积物释放。
The concentrations of OCPs in bottom water in mostly sample sites were higher than in surface water, which indicated that OCPs in bottom water were mainly derived from the release of the sediments.
