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.

我们对分布于从加利福尼亚州洪堡湾至华盛顿州北部的9个河口内的28个受干扰程度最低的潮间带沼泽、海草床与潮林湿地样点，开展了土壤碳储量测定工作。本数据集包含168个土壤柱芯样品，涵盖沿柱芯深度的容重数据，以及土壤柱表层1米（或更深层）的子样品碳含量。针对每个采样位点，数据集还收录了湿地地表高程、孔隙水盐度、孔隙水pH值以及优势植被类型等相关信息。本数据集配套发表于《Global Change Biology》期刊的Kauffman等人（2020）的研究论文。
