Zusammenfassung:Net primary productivity (NPP) plays a pivotal role in the global carbon balance but estimating the NPP of underwater habitats remains a challenging task. Seaweeds (marine macroalgae) form the largest and most productive underwater vegetated habitat on Earth. Yet, little is known about the distribution of their NPP at large spatial scales, despite more than 70 years of local-scale studies being scattered throughout the literature. We present a global dataset containing NPP records for 246 seaweed taxa at 429 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 taxonomic and methodological information. The dataset presented here 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. Measurement(s) Seaweed net primary productivity Technology Type(s) photorespirometry, biomass accumulation, eddy covariance Factor Type(s) Annual per-area net primary productivity Sample Characteristic - Organism Phaeophyceae • Rhodophyta • Chlorophyta Sample Characteristic - Environment marine biome Sample Characteristic - Location Global
