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

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.

本数据集收录了在东北太平洋海域使用 Juday 网收集的浮游动物出现数据。这些数据作为国际鲑鱼年（IYS）公海考察项目的一部分，于2020年3月至4月期间收集，旨在进一步增进对底层食物网结构和影响鲑鱼早期海洋越冬存活的因素的认知。2020年在37个站位处，将 Juday 网以0.1平方米的网口面积和160微米的网目尺寸投放到200米深的水层。样品在实验室进行处理。物种分类被确定为最低的税阶。在可能的情况下，确定了性别和生命阶段。若需获取计数、丰度和生物量测量数据，请与列出的联系人联系。
