Zooplankton abundance from Multinet samples at selected stations in the LTER Hausgarten in Fram Strait during the Polarstern expedition PS85 (ARK-XXVIII/2)@en

Depth-stratified mesozooplankton samples were collected in Fram Strait at selected stations of the LTER Hausgarten with a multinet midi (Hydrobios, 150 µm mesh, opening 0.25 m2) during the RV Polarstern expedition PS85 (ARK-XXVIII/2). We conducted vertical tows that were standardized to the five depth intervals 0 – 50 m, 50 – 200 m, 200 – 500 m, 500 – 1000 m and 1000 – 1500 m (or bottom depth). The volume of filtered water was recorded with a digital flowmeter. All net samples were preserved in a 4% formaldehyde seawater solution buffered with Borax onboard. The samples were analyzed with the imaging system ZooScan using the methodology described in Cornils et al. (2022). The images taken with the ZooScan system can be viewed in the EcoTaxa image datasets (see below).*ps85在极星号（RV Polarstern）第PS85航次（ARK-XXVIII/2）考察期间，研究团队于弗拉姆海峡内选定的长期生态研究（Long-Term Ecological Research, LTER）豪斯加滕站位，采用Midi型分层浮游生物网（Hydrobios公司生产，网目孔径150 μm，有效开口面积0.25 m²）采集深度分层的中型浮游动物（mesozooplankton）样本。本次采样采用标准化垂直拖网方式，预设5个深度分层区间：0–50 m、50–200 m、200–500 m、500–1000 m及1000–1500 m（或至实际海底深度）。过滤水体的体积通过数字流量计进行记录。所有网采样本均在船上采用硼砂缓冲的4%甲醛海水溶液完成固定保存。本数据集样本借助ZooScan成像系统，并依照Cornils等人2022年发表的方法开展分析。通过ZooScan系统获取的浮游动物图像可在EcoTaxa图像数据集（详见下文）中查看。*ps85
