The Mesopelagic Mesozooplankton and Micronekton Database (MMMD) compiles quantitative data on the distribution and density of mesopelagic (200-1000 m) mesozooplankton and micronekton (0.2-20 mm and 20-200 mm) species, using 258 published and unpublished sources spanning from 1880 to 2016. This extensive dataset includes 266,611entries, covering a broad temporal, spatial range and diel changes with varying levels of completeness. The data were standardized to address inconsistencies in sampling methods, mesh sizes, and taxonomic classifications. Despite some limitations, including gaps in spatial and depth coverage, the database provides a valuable resource for the mesopelagic macro-ecological research, which is updatable. Comparisons with existing databases underscore its unique contributions to the study of mesopelagic ecosystems.
中层海洋中型浮游生物和小型洄游生物数据库（MMMD）汇编了关于中层海洋（200 - 1000米）中型浮游生物和小型洄游生物（0.2 - 20毫米和20 - 200毫米）物种分布和密度的定量数据，使用了1880年至2016年期间的258个已发表和未发表的资料来源。这个广泛的数据集包含266,611条记录，涵盖了广泛的时间、空间范围以及具有不同完整程度的昼夜变化。数据经过标准化处理，以解决采样方法、网目尺寸和分类学分类方面的不一致问题。尽管存在一些局限性，包括空间和深度覆盖方面的空白，但该数据库为中层海洋宏观生态研究提供了宝贵的资源，并且是可更新的。与现有数据库的比较突出了其对中层海洋生态系统研究的独特贡献。
