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.本全球数据集汇集了242种海藻在419个独立地点的NPP（初级生产力）记录，这些地点遍布所有大陆，从潮间带到55米深度。所有记录均已标准化为年地面碳产量（g C m-2 yr-1），并附有详细的分类学和方法论信息。该数据集为水下植被初级生产力的地区、区域及全球比较研究提供了基础，对于深入理解海藻在全球海岸碳循环中所扮演角色具有重要意义。
