Data from: Carbon burial in Cornell's experimental ponds

Ponds are globally abundant and important to the global carbon cycle. While ponds have large greenhouse gas emissions, they may also sequester large amounts of carbon in their sediments. Here, we studied carbon burial rates in 22 experimental ponds without watersheds, where carbon sequestration comes solely from autochthonous primary production. The ponds were built identically in 1964 at Cornell University, and have since experienced different management strategies. This dataset includes two files: (1) spreadsheets related to carbon burial calculations (e.g., measuring sediment thickness, estimates of loss-on-ignition, and carbon burial rates), and (2) spreadsheets of historical management practices for our study ponds. These datasets accompany a manuscript accepted at Limnology and Oceanography Letters.池塘在全球范围内分布广泛，且对全球碳循环具有关键作用。尽管池塘会产生大量温室气体排放，但其沉积物中可固存大量碳。本研究针对22个无集水区的实验池塘开展了碳埋藏速率研究，该类池塘的碳固存仅来源于内源初级生产。这些池塘于1964年在康奈尔大学（Cornell University）统一建成，此后各自采用了不同的管理策略。本数据集包含两类文件：(1) 与碳埋藏计算相关的电子表格（涵盖沉积物厚度测量、烧失量估算及碳埋藏速率计算等内容）；(2) 本研究涉及池塘的历史管理措施电子表格。本数据集配套一篇已被《Limnology and Oceanography Letters》（湖沼学与海洋学快报）录用的研究论文。
