Temporal and spatial variation of zooplankton in relation to environmental variables in the upper Santos estuary, São Paulo, Brazil

Zooplankton samples were collected through oblique trawls with a 200 µm net with a flow meter during low tide, at 4 sampling sites with different degrees of salinity in the upper Santos estuary, in 28 campaigns carried out between 2014 and 2023, to analyze the spatial and temporal variations in the structure and abundance of zooplankton in relation to environmental variables using data from a long-term monitoring, in this way, contributing to the update of knowledge about the zooplankton community of the Santos estuary.

本数据集的浮游动物(Zooplankton)样本采集工作于2014年至2023年间完成，累计开展28个采样航次：在桑托斯河口(Santos estuary)上游盐度各异的4个采样点位，于低潮期采用搭载流量计的200μm网目浮游生物网进行斜向拖网采集。本研究依托该长期监测数据，旨在分析浮游动物群落结构与丰度的时空变异特征及其与环境变量的关联，进而为更新学界对桑托斯河口浮游动物群落的相关认知提供支撑。
