A global dataset of seaweed net primary productivity

This global dataset contains a compilation of NPP records for 242 seaweed species at 419 individual sites distributed on all continents from the intertidal to 55 m depth. All records are standardized to annual aerial carbon production (g C m-2 yr-1) and are accompanied by detailed taxonomical and methodological information. The dataset provides a basis for local, regional and global comparative studies of the NPP of underwater vegetation, and is pivotal for achieving a better understanding of the role seaweeds play in the global coastal carbon cycle.

本全球数据集整合了来自全球各大陆419个独立采样位点的242种海藻的净初级生产力（Net Primary Production，NPP）记录，采样深度覆盖潮间带至55米水深。所有记录均已统一标准化为年度空中碳生产量（g C m⁻² yr⁻¹），并附带详细的分类学与方法学信息。本数据集可为水下植被净初级生产力的本地、区域及全球比较研究提供基础，同时对于深入理解海藻在全球沿海碳循环中所发挥的作用至关重要。
