(Table 1) Silicon concentration in Antarctic plankton

The paper is based on data collected during Cruise 11 of R/V Akademlk Kurchatov. Methods for primary treatment of marine plankton specimens and determination of silicon contents are described. Species composition of phytoplankton present in the specimens is given. Silicon concentration in marine plankton is found to vary from 0.1 to 3.1% of wet or from 7 to 13% of dry weight. Silicon concentration in mixed plankton depends on proportions of phyto- and zooplankton, on prevalence of particular diatom species in mixed plankton, and on daily variations in proportions of phyto- and zooplankton in mixed plankton. Average silicon concentration in diatoms from the Atlantic province of the Antarctic is 1.1% of wet or 10% of dry specimen weight.

本研究基于“库尔恰托夫院士号”（R/V Akademik Kurchatov）第11次科考航次采集的数据集。文中详述了海洋浮游生物标本的前处理方法与硅含量测定流程，并给出了标本中浮游植物的物种组成。研究发现，海洋浮游生物的硅含量占湿重的比例为0.1%至3.1%，占干重的比例则为7%至13%。混合浮游群落的硅浓度受多重因素影响：包括浮游植物与浮游动物的占比、混合群落中特定硅藻物种的优势度，以及浮游动、植物在混合群落中的日际占比变化。南极大西洋海域分区的硅藻平均硅含量占其湿重的1.1%，占干重标本的10%。
