We present the longest available dataset (by 15 years) of estuarine zooplankton abundance worldwide. Zooplankton have been monitored throughout the upper San Francisco Estuary from 1972 -present due to its status as a central hub of California water delivery and home to commercially important and endangered fishes. We integrated data from five monitoring programs, including over 300 locations, three size-classes of zooplankton targeted with different gears, over 80,000 samples, and over two billion sampled organisms. Over the duration of this dataset, species invasions have driven community turnover, periodic droughts have occurred, and important fishes have declined, likely due in part to reduced food supply from zooplankton. Data from the individual surveys have been used in prior studies on issues related to species invasions, flows, fish diets and population dynamics, zooplankton population dynamics, and community ecology. Our integrated dataset offers unparalleled spatio-temporal scope to address these and other fundamental ecological questions.
我们提供了全球范围内现有最长的（长达 15 年）的河口浮游动物丰度数据集。由于旧金山河口是加利福尼亚州输水的中心枢纽，也是具有商业重要性和濒危鱼类的家园，因此自 1972 年以来一直在对其进行浮游动物监测。我们整合了五个监测项目的数据，其中包括 300 多个地点、三种不同渔具目标的浮游动物大小类别、超过 8 万份样本和超过 20 亿个采样生物。在这个数据集的持续时间内，物种入侵导致了群落更替，周期性的干旱发生了，重要的鱼类也减少了，这可能部分是由于浮游动物提供的食物减少。个体调查的数据曾被用于先前与物种入侵、水流、鱼类饮食和种群动态、浮游动物种群动态以及群落生态学相关的研究。我们的综合数据集提供了无与伦比的时空范围，可用于解决这些及其他基本生态问题。
