Benthic fauna refers to all fauna that live in or on the seafloor, which researchers typically divide into size classes meiobenthos (32/64 µm-0.5/1 mm), macrobenthos (250 µm-1 cm), and megabenthos (>1 cm). Benthic fauna play important roles in bioturbation activity, mineralization of organic matter, and in marine food webs. Evaluating their role in these ecosystem functions requires knowledge of their global distribution and biomass. We therefore established the BenBioDen database, the largest open-access database for marine benthic biomass and density data compiled so far. In total, it includes 11,792 georeferenced benthic biomass and 51,559 benthic density records from 384 and 600 studies, respectively. We selected all references following the procedure for systematic reviews and meta-analyses, and report biomass records as grams of wet mass, dry mass, or ash-free dry mass, or carbon per m and as abundance records as individuals per m. This database provides a point of reference for future studies on the distribution and biomass of benthic fauna.
底栖动物是指生活在海底或海底的所有动物，研究人员通常将其分为小型底栖动物（32/64 μm-0.5/1 mm）、大型底栖动物（250 μm-1 cm）和巨型底栖动物（>1 cm）。底栖动物在生物扰动活动、有机质矿化和海洋食物网中发挥着重要作用。要评估它们在这些生态系统功能中的作用，需要了解它们的全球分布和生物量。因此，我们建立了 BenBioDen 数据库，这是迄今为止最大的海洋底栖生物量和密度数据开放获取数据库。该数据库共包含 11792 个地理参考的底栖生物量和 51559 个底栖密度记录，分别来自 384 项和 600 项研究。我们按照系统评价和荟萃分析的程序选择了所有参考文献，并以克湿重、干重或无灰干重、每平方米碳或个体数报告生物量记录，以每平方米个体数报告密度记录。该数据库为未来底栖动物分布和生物量的研究提供了参考点。
