Abstract

The data on chlorophyll content in the water and bottom sediments in freshwater Rybinsk Reservoir (Upper Volga) and Aniva Sea Bay (Sea of Okhotsk) are summarized. The average concentration of chlorophyll a in plankton of the reservoir is 23.0 ± 1.9 μg/L, in the bay 0.77 ± 0.06 μg/L, in the bottom sediments 144.2 ± 14.9, and 8.2 ± 0.7 μg/g in the dry sediment, respectively. Correlations between pigment concentrations in the euphotic zone, in the aphotic bottom layer, the whole column of water, and the upper layer of bottom sediments, as well as the relationship of pigments with depth (within 6–100 m) and transparency (from 1 to 18 m), were revealed. It is shown that the general relations for two waterbodies are approximated by nonlinear equations with determination coefficient values (R²) from 0.37 to 0.93. The patterns of the relationship between pigment indices are similar in both waterbodies.

淡水和海洋水体中叶绿素a含量的比较分析

摘要

总结了淡水雷宾斯克水库（上伏尔加河）和阿尼瓦海湾（鄂霍次克海）的水和底部沉积物中的叶绿素含量数据。水库浮游生物中叶绿素a的平均浓度分别为23.0±1.9μg/ L，海湾0.77±0.06μg/ L，底部沉积物144.2±14.9和干燥沉积物中的8.2±0.7μg/ g 。富营养区，无光底层，整个水柱和底部沉积物上层中颜料浓度之间的相关性，以及颜料与深度（6-100 m内）和透明度（从1开始）的关系至18 m）。结果表明，两个水体的一般关系由具有确定系数值（R²）从0.37到0.93。两种水体中色素指数之间关系的模式相似。
