Dataset: Carbon stocks and environmental driver data for blue carbon ecosystems along the Pacific coast of North America

This data release contains carbon stocks data and down-core profiles of bulk density and organic matter or carbon content for 1284 sediment cores from blue carbon ecosystems along the Pacific coast of North America compiled from 69 data sources. Ecosystem types are tideflats, seagrass meadows, emergent marsh, mangroves, and tidal swamps. In addition to carbon data, the data release includes metadata on each of the 69 data sources, the geographic positions and standardized tidal elevation (z*) of sediment cores, and core-level environmental data such as ecoregion, Köppen-Geiger climate zone, sediment grain size data, and vegetation type. These data form the basis for the publication: Janousek et al. (2025), “Blue carbon stocks along the Pacific coast of North America are mainly driven by local rather than regional factors”.

本数据发布包含汇编自69个数据源的、北美太平洋沿岸蓝碳生态系统（blue carbon ecosystems）中1284个沉积物岩心的碳储量数据，以及岩心深度剖面的体积密度、有机质或碳含量数据。生态系统类型包括潮滩、海草草甸、挺水沼泽、红树林和潮汐沼泽。除碳数据外，本数据发布还包含69个数据源各自的元数据（metadata）、沉积物岩心的地理位置与标准化潮汐高程（z*），以及岩心尺度的环境数据（如生态区、柯本-盖格气候带、沉积物粒度数据和植被类型）。这些数据构成了Janousek等人（2025）发表的《北美太平洋沿岸蓝碳储量主要受局地因素而非区域因素驱动》一文的基础。
