1) bottom sea waters
近底层海水
2) bottom water
底层海水
1.
In order to find degree and extent of environmental impact on bottom water from cage culture in Yaling Bay, a field investigation was done from Apr.
哑铃湾网箱养殖使底层海水中TO C、SS、有机污染物和溶解态氮磷营养盐都有不同程度的增加,春、夏、秋3季D O有不同程度的下降,SS、C O D M n、N H4+、D IN、D IP的增加相对更显著,而对pH值、盐度、水温和冬季D O的影响较小;在水质状况上,D O、B O D5受影响最大,其次是D IP;养殖期较长的网箱区底层海水在春、秋2季已达到富营养化水平。
2.
Based on field investigation in the cage culture area,Yaling Bay,from Apr 2002 to Jan 2003,the percentages of various forms of phosphorus in bottom water of cage culture area in total phosphorus(TP) and total dissolved phosphorus(DTP) were calculated.
根据2002年4月~2003年1月在哑铃湾网箱养殖区的水化学现场调查,分析了底层海水中P的形态构成以及各种形态P的时空分布特征,讨论了各种形态P之间的线性相关性以及影响溶解态P(DTP)和溶解无机P(DIP)的环境因素,比较了网箱区与附近海区溶解态P的含量差异。
3.
Based on the field investigation over bottom water at cage culture area, Yaling Bay from April 2002 to January 2003, the concentration difference and seasonal change in dissolved nitrogen and phosphorus of bottom water at cage culture area and reference station were analyzed.
根据2002年4月至2003年1月在哑铃湾网箱养殖区水化学的现场调查,分析了网箱区和对照点底层海水中溶解无机氮磷的含量差异和季节变化特征,讨论了溶解态无机氮磷与环境因子的线性相关性,并对哑铃湾网箱养殖区底层海水的富营养化水平进行评价。
3) benthic-pelagic coupling
海底-水层耦合
5) near surface
近海底
1.
Numerical simulation of flow around submarine operating close to the bottom or near surface;
潜艇近海底与近水面绕流数值模拟研究
6) Near-bottom current
近底层流
