Diatom concentrations and fluxes from marine sediment core AMD14-204_CASQ

Relative contribution of the “marginal ice zone”, “drift-ice/pack-ice” and “summer subsurface” diatom indicator groups, diatom valve and Chaetoceros resting spore concentrations (valves or spores/g), diatom valve and Chaetoceros resting spore fluxes (valves or spores/unit surface area/yr), and total diatom fluxes (valves and spores/unit surface area/yr) from the marine sediment core AMD14-204 that was retrieved from the West Greenland shelf, offshore Upernavik, and which spans the last ca. 9,000 years.

本数据集涵盖取自西格陵兰陆架乌佩纳维克近海的海洋沉积岩芯（marine sediment core）AMD14-204的相关指标数据，具体包括：边缘冰区（marginal ice zone）、流冰/密集浮冰（drift-ice/pack-ice）及夏季次表层硅藻指示类群的相对贡献占比；硅藻（diatom）壳体与角毛藻休眠孢子（Chaetoceros resting spore）的浓度（单位：壳体/孢子每克）；硅藻壳体与角毛藻休眠孢子的通量（单位：壳体/孢子每单位表面积·年）；以及总硅藻通量（壳体与孢子合计，单位：每单位表面积·年）。该岩芯的沉积序列覆盖过去约9000年。
