CSIRO Micronekton Database: 1992 to 2018

Micronekton are small (~2-20 cm) free-swimming pelagic organisms. Ecologically, they are the mediators between primary production to higher trophic orders, by providing the trophic link between the mesozooplankton and apex predators. Here we describe CSIRO’s micronekton data holdings collected from 1992 to 2018 from 13 surveys within six areas around southeastern Australia and the Southern and Indian Oceans. Surveys include depth stratified sampling, integrated sampling and some diurnal and seasonal replication. Comparisons between surveys were made by standardising data using a consistent method for volume filtered estimates.小型游泳生物（micronekton）指体长约2至20厘米的自由游动大洋性生物。从生态学角度而言，它们是初级生产与更高营养级之间的中介，承担了中型浮游动物（mesozooplankton）与顶级捕食者之间的营养纽带功能。本研究详述了澳大利亚联邦科学与工业研究组织（CSIRO）的小型游泳生物数据集馆藏：该数据集采集于1992年至2018年间，涵盖澳大利亚东南部海域、南大洋及印度洋周边6个区域内开展的13次科考调查。本次科考采用分层深度采样、集成采样方案，并开展了部分昼夜与季节重复采样工作。为实现不同科考调查间的横向可比，研究团队采用统一方法对数据进行标准化处理，以获取标准化的滤水体积估算值。
