Size, sinking rate, and flux of fecal pellet and Gyrodinium cell sampled in the austral summer of 2017, 2019, 2020 in the Indian sector of the Southern Ocean.

Drifter sediment trap was deployed in the Indian sector of the Southern Ocean from December 2016 to January 2017, and in January 2018, and from December 2019 to January 2020. Fecal pellet and Gyrodinium cells were sampled using a drifter sediment trap. Size, sinking rate, and flux of fecal pellets and Gyrodinium cells were calculated using microscopic observation and an isotope-ratio mass spectrometer. The summary of the fecal pellets and Gyrodinium cells data is listed in the Excel file.2016年12月至2017年1月、2018年1月，以及2019年12月至2020年1月期间，漂流式沉积物捕集器（drifter sediment trap）在南大洋印度洋扇区完成布放。本研究采用该捕集器采集粪球粒（fecal pellet）与裸甲藻（Gyrodinium）细胞样品。借助显微观测与同位素质谱仪（isotope-ratio mass spectrometer），研究人员计算得到粪球粒及裸甲藻细胞的粒径、沉降速率与通量。粪球粒与裸甲藻细胞相关数据的汇总信息已整理至Excel文件中。
