Environmental data and microorganism composition from the HAVOC sea ice ridge study during the MOSAiC expedition (PS122) in the Central Arctic Ocean 2019-2020@en

This dataset gives an overview of environmental data including temperature, salinity, brine volume fraction (for sea ice only), dissolved nutrients, particulate organic carbon and nitrogen, particulate elemental concentration, as well as chlorophyll a concentrations, bacterial production and the abundance of microorganisms either enumerated using light microscopy (organisms between 20 µm – 300 µm) or flow cytometry (FCM for organisms smaller than 20 µm) of HAVOC sea ice ridge specific samples, taken during the Multidisciplinary drifting observatory for the study of Arctic Climate (MOSAiC) during leg 2, 3 and 4 (December 2019 – August 2020). Additional expedition and sampling details can be found in the ECO-overview paper (Fong et al., 2024). We thank all persons involved in the expedition of the Research Vessel Polarstern during MOSAiC in 2019-2020 (AWI_PS122_00) as listed in Nixdorf et al. (2021). […]本数据集收录了HAVOC海冰脊专属采样样品的多类环境数据，涵盖仅针对海冰的温度、盐度、盐水体积分数，溶解态营养盐、颗粒态有机碳与氮、颗粒态元素浓度，以及叶绿素a浓度、细菌生产力；同时包含通过光学显微镜（light microscopy，计数20 µm~300 µm尺寸的生物）或流式细胞术（flow cytometry, FCM，用于计数小于20 µm尺寸的生物）统计得到的微生物丰度数据。所有样品采集于北极气候多学科漂移观测站（Multidisciplinary drifting observatory for the study of Arctic Climate, MOSAiC）2019年12月至2020年8月的第2、3、4航次。 更多航次与采样细节可参阅ECO综述论文（Fong等，2024）。 我们谨向2019-2020年MOSAiC航次中极星号（Research Vessel Polarstern）科考队的全体参与人员致以谢意，相关人员名单详见Nixdorf等（2021），本次航次编号为AWI_PS122_00。 [...]
