Benthic prokaryotes include Bacteria and Archaea and dominate densities of marine benthos. They play major roles in element cycles and heterotrophic, chemoautotrophic, and phototrophic carbon production. To understand how anthropogenic disturbances and climate change might affect these processes, better estimates of prokaryotic biomasses and densities are required. Hence, I developed the ProkaBioDen database, the largest open-access database of benthic prokaryotic biomasses and densities in marine surface sediments. In total, the database comprises 1,089 georeferenced benthic prokaryotic biomass and 1,875 density records extracted from 85 and 112 studies, respectively. I identified all references applying the procedures for systematic reviews and meta analyses and report prokaryotic biomasses as g C cm sediment, g C g sediment, and g C m. Density records are presented as cell cm sediment, cell g sediment/ sulfide/ vent precipitate, and cell m. This database should serve as reference to close sampling gaps in the future.
底栖原核生物包括细菌和古菌，它们在海洋底栖生物的密度中占主导地位。它们在元素循环以及异养、化能自养和光养碳生产中发挥主要作用。为了了解人为干扰和气候变化可能如何影响这些过程，需要更好地估计原核生物的生物量和密度。因此，我开发了 ProkaBioDen 数据库，这是海洋表层沉积物中底栖原核生物生物量和密度的最大开放获取数据库。该数据库总共包含 1,089 个具有地理参考的底栖原核生物生物量记录和 1,875 个密度记录，分别从 85 项和 112 项研究中提取。我应用系统评价和荟萃分析的程序确定了所有参考文献，并报告了以 g C cm 沉积物、g C g 沉积物和 g C m 表示的原核生物生物量。密度记录以细胞 cm 沉积物、细胞 g 沉积物/硫化物/通风沉淀和细胞 m 表示。该数据库应作为未来填补采样空白的参考。
