Dataset: Carbon stocks in seagrass meadows, emergent marshes, and forested tidal swamps of the Pacific Northwest

We determined soil carbon stocks in least-disturbed tidal marshes, seagrass meadows, and tidal forested wetlands comprising 28 sites in nine estuaries from Humboldt Bay, California to northern Washington. The dataset of 168 cores includes down-core bulk density and carbon content in subsamples from the top meter (or more) of the soil column. For each cored location, the data set also includes information on wetland surface elevation, pore water salinity, pore water pH, and dominant vegetation. This dataset accompanies the published paper Kauffman et al. (2020) in the journal Global Change Biology.

本研究测定了从加利福尼亚州洪堡湾至华盛顿州北部9个河口的28个样点内，受干扰程度最低的潮汐盐沼、海草床及潮汐森林湿地的土壤碳储量（soil carbon stocks）。本数据集包含168根土壤岩芯（cores）的相关数据，涵盖土壤柱（soil column）表层1米（或更深层）子样品的垂向剖面容重与碳含量。针对每个钻探采样点位，数据集还收录了湿地地表高程、孔隙水盐度、孔隙水pH值及优势植被的相关信息。本数据集对应发表于《Global Change Biology》期刊的Kauffman等（2020）研究论文。
