Macroalgal habitats are believed to be the most extensive and productive of all coastal vegetated ecosystems. In stark contrast to the growing attention on their contribution to carbon export and sequestration, understanding of their global extent and production is limited and these have remained poorly assessed for decades. Here we report a first data-driven assessment of the global extent and production of macroalgal habitats based on modelled and observed distributions and net primary production (NPP) across habitat types.

对大型藻类森林范围和产量的全球估计

大型藻类栖息地被认为是所有沿海植被生态系统中最广泛和最具生产力的。与日益关注它们对碳出口和碳封存的贡献形成鲜明对比的是，对它们的全球范围和产量的了解是有限的，而且几十年来这些评估仍然很差。在这里，我们报告了基于建模和观察到的分布以及栖息地类型的净初级生产 (NPP) 对全球范围和大型藻类栖息地产量的第一次数据驱动评估。
