Sediment characteristics in experimental seagrass meadows in Virginia, 2012

Using a large-scale restoration (>1700 ha) in the Virginia coastal bays as a model system, we evaluated the role of seagrass, Zostera   marina , restoration in carbon storage in sediments of shallow coastal ecosystems. Sediments of replicate seagrass meadows representing different age treatments (as time since seeding: 0, 4, and 10 years), were analyzed for % carbon, % nitrogen, bulk density, and organic matter content at 1-cm increments to a depth of 10 cm.

本研究以弗吉尼亚沿海海湾一处面积超1700公顷的大规模海草修复工程为模式系统，探究了大叶藻（Zostera marina）修复工程对浅海沿海生态系统沉积物碳储存的调控作用。针对不同修复时长梯度（即播种后时长：0年、4年与10年）的重复海草床样地沉积物，本研究以1厘米为间隔分层取样至10厘米深度，对其碳百分含量、氮百分含量、沉积物容重及有机质含量开展了分析测定。
