Juday Net Zooplankton Data from the 2020 Gulf of Alaska International Year of the Salmon Expedition@en

This dataset contains zooplankton occurrence data collected in the Northeast Pacific Ocean with a Juday net. These data were collected as part of the International Year of the Salmon (IYS) High Seas Expeditions conducted in March and April 2020, to further improve the understanding of the underlying food web structure and factors impacting salmon early marine winter survival. A Juday net (0.1 m2 mouth area, 160 um mesh size) was deployed to a depth of 200m at 37 stations in 2020. Samples were processed in the lab. Taxa were determined to lowest taxonomic rank possible. Where possible, sex and lifestage are determined. For count, abundance and biomass measurements, please reach out to the point of contact(s) listed.

本数据集包含使用Juday网（Juday net）在东北太平洋海域采集的浮游动物出现记录数据。该数据为2020年3至4月开展的国际鲑鱼年（International Year of the Salmon, IYS）公海科考航次的采集成果，旨在进一步深化对底层食物网结构以及影响鲑鱼海洋早期越冬存活率的各类因素的认知。2020年，研究人员在37个采样站位部署了口部面积0.1平方米、网孔尺寸160微米的Juday网，下放深度达200米。所有样品均在实验室完成处理，所有浮游动物类群均被鉴定至尽可能低的分类阶元；若条件允许，还会对个体的性别与生活史阶段进行鉴定。如需获取计数、丰度及生物量相关测量数据，请联系文中所列联系人。
